How Much Does Home Insulation Cost?

Are you wondering how much does home insulation cost? A fundamental part of keeping the home temperature comfortable with low electric bills is having your home winterized with insulation. It is crucial to keep the home safe and comfortable, whether it is warm or cold outside. But how much will home insulation cost? 

Average Home Insulation Costs

When you want home insulation done, the price varies depending on different factors and the type of insulation material you choose. It also depends on the location of your home. Furthermore, it depends if it is a new or old building, considering the region’s labor charges. 

So, to find out the estimated costs, you need the square feet to help reflect different price points. The cost can be lower or higher depending on the area you want to insulate. Here we have calculated it at a rate of $2 per sq. ft.

  • The Average Cost is Between $3,000 to $10,000
  • The Highest Cost Can Come to $24,0000
  • While the Lowest Cost Can Be $2,000

These costs are calculated for a 2,000 sq. ft. home.   

New Versus Existing Construction

When you start a new building project, it is the best time to add your insulation, as all the walls and ceilings are still open for adding insulation. Once homes are completed, you can add blown-in insulation to the open spaces like your attics, and for a new home compared to an existing one, it can cost you, on average, $1.00 less per sq. ft. 

Removing or Replacing Old Insulation

If the existing insulation degrades or does not work effectively, it might need replacing. While some insulation can last for years, some only last for 20 years. If the insulation is very old, it needs replacing. 

Removing the existing insulation can expose different toxic chemicals and requires a professional to complete the job safely. Insulation removal can range between $1 to $3 per sq. ft. 

When combined with the installation costs in an existing home, it means removal and replacement ranging between $2 to $8 per sq. ft. 

Different Home Insulations

You can find four types of home insulation methods used, each with different costs. 

Blanket Batts or Rolls

It is the most inexpensive home insulation and easy to install. The insulation fits into standard with wall studs, joists, and rafters. You can install it on ceilings and floors with a new home-building project. 

The insulation material comprises fiberglass and needs handling with care. You can find it made of cotton, plastic, or mineral wool. The average cost is between $0.65 to $2 per sq. ft.


Home insulation contractors use a machine to blow the insulation into gaps made of recycled cellulose like cardboard or newspaper. The fabric conforms to the space and works well in an existing home for hard-to-reach areas. The average cost is between $1.60 to $3.80 per sq. ft.

Foam Board 

It is a rigid form of insulation made for exterior insulation of the home below a siding. You can use it in basement insulation on the floor or unfinished walls. It is thin compared to blanket insulation but very efficient, costing between $2.45 to $3.70 per sq. ft.

Spray Foam

The spray foam you also blow in works well in hard-to-reach spaces. It has a liquid form of polyurethane that you spray into cavities. You have two types, open and closed-cell, with the last mentioned more expensive. It’s denser and more durable to trap heat. The average costs are $3.10 to $7.55.

Cost by Location for Home Insulation

Another factor determining the home insulation cost is where you plan to install it, as your home needs insulation from top to bottom to make it energy-efficient. 

Garage Insulation

While you rarely insulate the garage when building, it does not prevent you from doing this afterward. It helps when you want to create a living space above it. There are minimum charges implied by insulation companies, with an average cost between $0.25 to $1.30 per sq. ft. for a double garage, including the garage door.

The Basement

It is a place that typically does not need insulation but helps keep the area cool in the surrounding area in summer while warm in winter. On average, you can expect to pay $1.50 to $2.55 per sq. ft. 

The Attic

The most important part of insulating the home is your attic. As heat rises from below, you need more insulation in this section than in the walls. It helps to prevent the loss of warm air that rises. Here spray insulation is best to use, followed by batts or blow-in insulation. The cost varies between $1,500 to $6,500.

The Roof and Walls

 If you have problems retaining heat in the living space or want to convert your attic into a living space, roof insulation helps. For new construction, it helps to use foam board to lay beneath the shingles. Using batting or spray foam is easily done along the rafters for an existing roof. Average cost between $1,500 to $5,000.

While wall insulation is typical insulation done using mineral wool to fiberglass. You may find in your newly constructed home that they use spray foam. These insulations can range between $1 up to $5 per sq. ft. 

Final Thoughts

These are a few estimated costs for home insulation, and the labor can vary between $0.24 and $2.50 per sq. ft. It all depends on the installation method, equipment, and material used. So, if you want home insulation done, contact Universal Insulation Doctor for a free estimate today. 

What Attic Insulation is Best?

Looking to see which attic insulation is best? No matter how big your home is, it needs proper insulation to help regulate temperature and save on the utility bill. So, if you live in a freezing area with snowy winters, you need to have your attic insulated for better energy efficiency. 

Still, what attic insulation is best? The truth is you can find different types of insulation, and not one size fits all. But we here at Universal Insulation Doctor can help determine what will work best for your attic.  

It All Comes Down to The R-Value

For proper attic insulation, you need to understand the R-Value of a unit that attic insulation contractors use to determine the strength of the insulation. The R-Value is the capacity of the material and how it resists or transfers heat to heat loss. 

Hence, the R-Value gets affected by the type of material, the thickness, density, and where you plan to install it. So the higher the R-Value can trap heat flow better to prevent your home from turning into a freezer during winter or a sauna in the scorching heat. 

The recommended R-Value levels for the attic, according to the US Department of Energy, are as follows:

  • In warm climates, it is R30
  • For temperate climate, it is R38
  • And for a freezing environment, it is R49

Type of Insulation Material Used for Attics 

While having a higher R-Value used in the insulation material, it doesn’t mean it is the best insulation choice for the attic in your home. You can find different insulation materials with outstanding strengths and weaknesses. Furthermore, some attics might work best with a specific fabric. So, you can find the following attic insulation materials used often:


The material is not your highest quality option but remains popular to use. The R-Value ranges from 2.2 up to 4.3 when using high-density fiberglass. So, attic insulation performs at its worst even when used in insulation construction with home renovations. 

The main advantage of fiberglass is that it is affordable and helps expert moisture that helps in high humidity areas. Neither does the fabric shrink; it is fire-resistant, while bugs avoid chewing on it.


You find cellulose attic insulation in the form of recycled paper or wood, claiming it is a green product, yet most of the time, it does not pass the green assessment. Furthermore, there are concerns as it is a natural flammable product even if treated with anti-flammable chemicals.

So, it is a fire hazard compared to using fiberglass, but it is inexpensive and 25% cheaper than fiberglass. Hence, it has more negatives than benefits:

  • First, it does not do well with moisture and is rendered useless when wet as it collects and holds water. Thus, you can find it develops mildew and mold with time. 
  • Cellulose also sags with time and works better with wall insulation than in the attic. 
  • Lastly, it creates a lot of dust when installed.

Mineral Wool 

The fabric is a melted-down stone from steel mills and is mainly used throughout Canada and Europe. The attic insulation material is costly but has loads of advantages. First, it creates a fire barrier as it only starts to burn at 1,8000°, and every home is safe.

It is a water warrior as it is water-resistant even with the worst leak. Furthermore, it creates a sound barrier to block outside noise. But it does have one drawback, and that is inhaling it during the insulation is cancerous. 

Hence, you must proceed with extra caution when present with the insulation. 

Cotton/Denim Insulation  

Cellulose Attic Insulation

Yes, this form of attic insulation comes from recycled blue jeans. It is also viable insulation as it has high performance with an R-Value of 3.7 and above. In addition, it can trap heat and is safe compared to other materials. But it is expensive. 

Open and Closed Foam Insulation 

You can find two types of foam used: open and closed. Open cell foam presents you with an R-Value of 3.5 while the closed cell is a whopping R7. Yet, this form of insulation is not recommended in residential buildings and is more for commercial to industrial use. 

You get exceptional air leakage to prevent and help to expand your building envelope at the attic roofline and help if your HVAC systems are found at floor level. Furthermore, it works well with water and is impenetrable to it. 

Hence, you will have less mold and mildew building, which is durable as it never loses efficiency to last decades. The foam also serves a dual purpose as you can apply it to rooflines to fortify the structure and block sound. 

But it can hit your wallet hard. In addition, it can shrink and requires a professional installer to do it for you. Still, that is not all, as you can find different types of attic insulation methods as well. 

Popular Insulation Methods Used in The Attic 

Attic insulation you can do in four ways to achieve the best results.

Batt Insulation Method

You get the batts in rolled-up sheets with interweaving fibers held in place with adhesive binders. You find it available in fiberglass, mineral wool, or denim. These types of insulation work well in attics as it covers an extensive range. 

It works well with little to no obstruction on the floor with enough headroom to work. There should not be prior insulation, and it needs to have horizontal wooden rods to run the fabric between. 

Blown-In Insulation

It is also known as loose-fill insulation packaged as tiny chunks in huge bags with a blowing machine. The fabric comprises fiberglass or mineral wool and is perfect for filling those tight voids in the attic. 

Spray Foam Attic Insulation 

The spray foam is typically paired with blanket insulation to help seal gaps. It is an effective way for attic insulation. The foam you spray into cracks creates a solid foam, while blanket insulation is inexpensive to use on floors and walls. The thick blanket pieces fit between gaps in the wooden frames or around pipes, and more. 

Final Thoughts 

These are some of the best attic insulation you can find and how much you need to the price depends on where you live and how old your home is. We recommend you contact us here at Universal Insulation Doctor to provide a free estimate to have your attic insulation done. Together we will look at different options to suit your budget. 


Insulation Checklist: Know What to Insulate and Why

Insulation is a crucial structural feature in any house nowadays. It brings several benefits, including a decrease in your energy bill and your carbon footprint, maintaining the house cooler during summer and warmer during winter without using the air conditioner or heather, helping you to maintain good health, and many other positive things. However, finding the right insulation is quite difficult.

There are many different types of insulation, and many areas in your house can get insulation, like your windows or attic, for example. So, how can you determine which area is the best to get insulated? And which type of insulation is ideal? Let’s see what to insulate and why through this checklist.

Check Your Walls

Whether you’re building a new home or renovating your current one, your exterior walls must have enough insulation to prevent any excessive draftiness in your home, or else the insulation may not work properly. The best way to check if your exterior walls have enough insulation is by turning off the power to the outlet and unscrewing its cover. If there’s insulation inside the walls, you’ll probably see it with a flashlight. A professional company can do a more thorough inspection, if necessary.

best insulation for crawl spaceBesides that, insulating your walls helps reduce sound transmission, protect against moisture damage and air leaks, and improve energy efficiency.

Since you are checking your walls, take this opportunity to check your windows and floors for the same reasons. Both can help improve heating and cooling control, moisture prevention, and reduce sound transmission.

Overall, if you want your house to be fully protected, you’ll probably need to insulate all walls, windows, and floors. Luckily, most professional insulation companies offer those services as a full insulation package for you, so it’ll be cheaper than insulating each area separately.

Check Your Attic

Probably the commonest type of insulation is attic insulation. Almost every house has an insulated attic. But why does this happen?

Insulating your attic is crucial since it is the highest place in the house, so it is most likely that the air escapes through any existing gap in the attic. Therefore, good attic insulation can help reduce attic temperatures and keep your home more comfortable. The “stack effect” happens when indoor air escapes from the top of the building, usually the attic, and outdoor air is sucked in from the bottom. As you can imagine, often poor attic insulation leads to it.

A visual inspection is the first step to properly inspecting your attic’s insulation. Check the insulation material, if there’s already insulation there, and see if the material is covering or is at level with the floor joists. After that, measure the R-Value of the attic insulation, if possible.

Check your basement as well; most heat loss in basements comes from under-insulating, so ensure to insulate thoroughly enough to seal off from the living spaces below. Insulate your basement walls, floors, and doors, specifically on sealing off from the living spaces below. Proper insulation also improves humidity levels in basements, making for a more enjoyable living area.

Check Your Garage

Insulating your garage door is a quick, easy process that will protect your home from inclement weather, make your garage door more durable and prevent external noise. The thought of insulating your garage may seem a bit strange at first, but don’t worry. It helps a lot since most garages are integrated with the houses, so the air that passes through them will also pass through the house. It also helps to protect your family’s privacy and keep pests away.

Understand Which Type of Insulation is Better for You

Overall, three types of insulation are between the most used and loved by homeowners. Of course, each has an area they work best in, as well as they have different prices and strengths. They are:

Spray Foam

Foam insulation is often wrapped around the pipes and wires in your home. It’s highly effective in reducing heat loss, improving air quality, and increasing energy efficiency. The most common form of foam insulation is acrylic foam, which is generally lighter than other types of foam boards. However, spray foam is the most efficient one. Anyway, foam insulation comes in many different formats and densities, so you can find the product that best fits your needs.

It can be applied to almost any part of your home, making it an ideal choice for anyone looking for a reliable and safe way to make their home temperature-efficient and energy-efficient. This type of insulation has three variants: polyisocyanurate, extruded polystyrene, and expanded polystyrene. The first two are similar because they both provide excellent R-values (thermal resistance values). At the same time, the third has the highest R-values among all types of insulations available today.

Blow-in Insulation

Also known as loose-fill insulation, it is one of the commonest types. It is very useful because you can use it in walls, ceilings, crawl spaces, and attics without disturbing the structures. This makes it ideal for areas where normal insulation would not be suitable. It can be installed without disrupting existing systems, and because it’s made of fiberglass, cellulose, or mineral wool; it’s great for walls, ceilings, and attics.

Batt Insulation

Batts and rolls are commonly used, as they are not as expensive as other forms of insulation, and they give you a lot of bang for your buck. You can DIY them yourself, which makes this type of insulation very popular with homeowners. It is also one of the cheapest types of insulation, and it can be made of natural fibers, fiberglass, plastic fibers, or mineral wool.

Hire a Professional Insulation Company

A professional insulation company can help you with installation and inspection, including choosing the right type and material for your house, since they are experts that work with insulation all day, every day.

If you live in the United States, Universal Insulation Doctor is the best fit for you since they offer several services, including those stated earlier, and even air duct cleaning. Check our website out to request a free inspection easily.

How to Choose the Right Home Insulation Company for Your Needs

Although it was always famous and very useful, nowadays more and more people are enjoying the benefits of insulation. Unfortunately, not all houses come with it, and even those with insulation may need to change it or renovate it. A homeowner needs to have the number of a good insulation company at hand. But how can one discover which company is the best? It may seem a hard task, but it isn’t. Let me show you some tips on choosing the right home insulation company for your needs.

  • What is Insulation?

Before choosing the right insulation company, you must know what insulation is and its benefits to understand why certain companies are better than others.

Overall, any insulation’s purpose is to reduce heat transfer through an enclosure. The most common means of achieving this is using appropriate materials designed or adapted to slow heat transfer in a particular manner. Reducing the heat transfer commonly involves increasing the resistance (or “R-value”) of insulating materials such as wood fiber, mineral wool, polystyrene, polyurethane foam, rock wool, and others. Asbestos was once a popular insulation material but has been banned in many countries because of health concerns. Insulation can be applied on each side of a building – the exterior wall (building enclosing) and interior wall (the enclosure within the building).

floor insulationThe exterior insulation requires outer cladding material over the support structure of the building. The material must be excellent since it has to provide security while being aesthetically appealing. Generally, the exterior insulation is weather-resistant, especially in places where the weather is extremely unpredictable or violent.

  • What are the Benefits of Insulation?

The benefits of insulation depend on what type of insulation you have and the material used. Usually, when choosing which insulation to install in your house, you select the kind that will bring you the most needed benefits. Let’s see the commonest benefits that most insulations bring.

Think about insulation as a barrier between your home and mother nature. Heat naturally flows from a warm to a cool place. As a result, many poorly insulated homes end up heating attics or even losing heat to the outside during the cold months of the year. The contrary happens in the summer, which means the house gets hotter since the heat is flowing into it because the outside is hotter and needs to cool down. Insulation helps hinder this natural process, thereby keeping a home warm in winter and cool in summer while lowering energy bills.

Yes, it helps you to save money. After all, you won’t need to spend so much on an air conditioner during summer or heathers during winter because your home won’t get as hot or cold as it was before. Besides, poor insulation can cause your HVAC system to work overtime, costing you more money in energy bills. Well-insulated homes always stay naturally warm or cool, which means you’re saving money on energy waste.

And the benefits don’t stop there. Insulation helps you to be healthier because of less touch with the outside air and weather. According to The Harvard School of Public Health, through an estimation, if every family in the United States properly insulated their houses, there would be a decrease in many cases, including 110,000 fewer sick days every year, 6,500 fewer asthma attacks every year, and even 240 less premature deaths every year.

Since 12% of your carbon footprint is a result of your use of electricity, 15% of it consists of your use of coal, gas, and oil, and 50 to 70% of the energy that your house uses consists of cooling and heating, insulation helps to protect the environment. According to the same Harvard study, we would see a great reduction of carbon dioxide in the atmosphere if every house in the world became insulated in ten years.

Summing up, the main benefits of insulation are:

  1. Insulation saves energy and, therefore, money;
  2. Insulation helps you to protect the environment by decreasing your carbon dioxide footprint;
  3. Insulation is great for your help;
  4. Insulation keeps your house cool during summer and warm during winter;
  • How to Choose the Right Home Insulation Company?

Now that we’ve cleared what insulation is and what good it can bring you, we can understand why choosing the right home insulation company is crucial. There are some details that, if you pay attention to, you can find a great company easily. They are:

  • Solid Reputation

Finding the right company for your insulation project is an important decision. The last thing you want to do is hire a company with a bad reputation. Therefore, it’s important to do some research before making your final decision.

Make sure the company you choose for your insulation project has a stellar reputation. Ask friends and family about recommendations, check with organizations like the Better Business Bureau and Angie’s List, and read online reviews. Most of the time, only highly rated companies will have the best workers and equipment that you need to insulate your home effectively.

  • Great Customer Service

Reading the customer’s reviews also helps you to see how the company treats its customers. Only hire a company with great customer service since they’ll be able to help you if some accident helps with the insulation or materials. Besides, no one likes to hire rude or incompetent people, right?

  • Experience

Hiring a company that has several years of experience in the insulation business is essential. The installation is not that simple, and every house has a different architecture and design, which makes it even harder to install insulation correctly. Therefore, only highly-skilled professionals can work with any building.

  • Insured and Licensed

Always hire contractors that are licensed and insured. Ask them to show their insurance or license before starting the service so you can be sure that you are secured and safe.

Finding the right home insulation company is not easy, but we hope this task gets simpler for you with these tips. If you live in the United States, Universal Insulation Doctor is the right fit for you.

Insulation Companies Near Me

Insulating your home is a big and important job. Chances are you are reading this article because you are looking for insulating services. However, improper insulation can be costly and it is essential to choose the best company for the job. Therefore, taking the time to educate yourself on what a quality insulation company looks like will far outweigh the benefits long-term.

What Makes a Good Insulation Company?

Overall, a reputable insulation company will save you time and money. To ensure safety and efficiency, consider the key factors below before choosing your ideal insulation company.

They Are Insured and Licensed

Insulating your home can be a dangerous job. Doing it yourself or hiring a handyman is typically not recommended. The material itself is loaded with chemicals and the job requires special equipment to be installed correctly. You do not want to risk becoming liable should the unthinkable happen. That’s why it is important to check if the company has proper credentials.

They Can Provide References

You can easily look up reviews and testimonials on Google and Facebook, but it’s also a good idea to ask your insulation company of choice if they have references in writing. References can give you peace of mind because they are usually provided by trustworthy individuals that have agreed to vouch for the company. The more references a company can provide, the better.

They Go Above and Beyond in Customer Service

As stated in the beginning, insulation is a big job and can be a relatively lengthy process. Old insulation removal may have to take place, or walls may have to be opened before installing anything new. For a project so invasive yet necessary, you want a company that will hold your hand through the process.

Constant communication, respect for your property, and a friendly and professional attitude will go a long way in reassuring you that your home is in the right hands.

They Offer a Wide Range of Services

Some projects require a little more than just insulation removal and installation. Services such as sanitization treatments, air duct cleaning, and even insulating different spaces in your home provide a one time solution for the entirety of the project. This way, you won’t have to worry about keeping track of multiple different companies, and it could even save you extra money.

They Are Reputable and Experienced

This goes without saying, but for many home projects (including insulation), experience is better. We’ve all heard the saying, “practice makes perfect” and that applies to the insulation company you choose. The more time they have spent perfecting their craft and professionalism, the more reassured you will be.

That is not to say newer companies are a bad choice. Ultimately, experience shows and the right company will not have a problem showing how trustworthy they are. Ask a lot of questions, look at reviews, and check for the appropriate credentials. If all checks out, all there is left to do is make the decision that is right for you.

How to Find the Right Insulation Company

Every homeowner’s idea of the right insulation company will vary slightly based on their needs. Regardless, there are a few commonalities when it comes to finding the right one for the job.

Conduct Research

Before taking to the internet, it doesn’t hurt to do a general evaluation of the problem area in your home, to assess what type of services you may require. Don’t worry about doing a full inspection, as the professional will do that for you in the last step. Simply estimating what sort of project you have on your hands will help you narrow down your search.

The first step after determining your insulation needs is to begin looking up companies near you that offer the right corresponding services. Evaluate at least three different companies by checking reviews, their websites, and what services they offer.


Next is the comparison phase. Does one company have a higher rating than the others? Does the lower rated one offer more of what you’re looking for? Are you impressed by another’s transparency by listing their certifications on their website? These are important questions to ask yourself when choosing the right insulation company for your specific needs.

Get Estimates

Lastly, call up the top contenders of your choice and invite them over to give you an estimate on the project. This is the last line of assessment when determining which company fits your needs the best. Further, this is also your time to ask all the questions you need, including references and proof of insurance and licensure. From there, simply choose the company you like the best!

Types of Insulation and Which Works Best

Not all insulation is created equal, and no two homeowner’s insulation needs are the same. From awkward crawl spaces and places with hard to reach corners, to simply needing a replacement project done, it can be a daunting task in trying to find the best option for you. Climate, r-value, your budget, and preferences all factor into choosing the right insulation.

In an effort to make the process simpler, here are the pros and cons of some popular insulation materials, as well as what they are used best for.

Attic Insulation

Your attic is a hotspot for affecting the temperature of your home and is the first line of defense when it comes to protecting from cold drafts and heat waves. This also means that it is the first to deteriorate and need replacing, so choosing a durable insulation material is key to keeping your home energy efficient. The most ideal example is spray foam insulation.

Spray foam provides a sturdy, airtight seal that extends to gaps and corners, making it a perfect choice for attics. The best part is that this type of insulation does not degrade over time like other options, and it can be applied in an open or closed-celled fashion. Let’s take a look at the pros and cons of this material.


  • Seals off all gaps and corners that other forms of insulation can’t reach.
  • Reduces heating and cooling costs by 50%.
  • Durable and impermeable to water, effectively abolishing mold and mildew growth.
  • Essentially lasts forever, as it does not lose its R-value over time.
  • Appropriately labeled as a “top of the line airtight seal.”


  • Requires a high level of expertise for proper installation.
  • Though it does not lose its r-value, it may start to shrink as it ages.
  • The process is more time consuming and invasive.
  • Spray foam does not meet building code requirements in some areas.

Another option for attics is loose fill fiberglass. Unlike their “batt” like counterparts, this colored fluff is applied with more flexibility to also fill in gaps and cracks. This is an ideal choice for homeowners looking for a more accessible and cost effective option. Here are the pros and cons for this material.


  • R-value can be built up without reducing the space in the attic.
  • Great for filling gaps and hard to reach corners.
  • Can be designed to be fire, mold, and pest resistant.
  • Not as expensive as other options.


  • Installation is a messy process.
  • Decreases in R-value over time.
  • Often requires additional factors such as installing a vapor barrier, venting, and air seals.
  • Must be installed by a professional.

Sub-Floor Insulation

Also known as underfloor or a crawl space, sub-floor insulation keeps temperatures regulated inside your home by preventing hot or cold air from escaping to the ground and vice versa. Just like you need insulation in your attic and throughout the rest of your home, sub-floor could be the missing puzzle piece to a more energy efficient home.

When it comes to which type of insulation you should choose for your crawl space, the most popular is fiberglass batts or rolls. Let’s take a look at the pros and cons of this material.


  • Can last for up to 50+ years.
  • Treated with fire retardant chemicals.
  • Most cost effective option.
  • Relatively easy installation due to being precut.
  • Can be made with recycled materials.
  • Double as sound proofing.


  • Poses some hefty health risks including eye and sinus irritation due to dust particles.
  • Does not provide a 100% seal and the R-value degrades over time.
  • Must be installed by a professional to ensure proper sealant and ventilation techniques.

Blown-in Insulation

Blown-in insulation is the process of using a machine to apply insulation rather than installing using man power. This is due to the material not being compact, but instead is loosely blown into the wall cavity. There are two types of blown-in insulation: loose fill fiberglass and cellulose. Since we’ve already discussed fiberglass, let’s take a look at what cellulose has to offer.

Cellulose is the most eco-friendly option as it uses shredded newspaper to be blown into the walls of your home. Here are the pros and cons of this material.


  • More airtight than fiberglass.
  • Contributes to the environment by cutting down on waste and reusing materials.
  • Easy installation in that there is no need for cutting and measuring.
  • It has a high R-value.
  • It is one of the more affordable options.
  • Can be treated to be fire, pest, and mold resistant.


  • Though it contains Boron, an insect repellant, there is a limited supply of the material.
  • It is not the cleanest process when installing and removing.
  • Its fire retardant properties lose strength over time, making it highly combustible.
  • It’s better for the environment, but not much better for your health when compared to fiberglass.

When Should I Replace My Insulation?

Your insulation is a vital part of your home’s protection system and is the main factor that helps regulate the temperature within your house.  Without it, it would be almost impossible to keep the temperatures at comfortable levels throughout the various seasons.

It doesn’t matter what kind of insulation you have in your home or the type of guarantee it has on it – over time, your insulation is going to lose its reliability and need to be replaced.

What are the signs that you need to get your insulation replaced? As an expert in the insulation industry, we have gathered together some simple indicators that let homeowners know their insulation is ready for replacement.

Things That Can Compromise Your Insulation Lifespan

There are several factors that can greatly reduce your insulation’s ability to properly insulate your home and may indicate that you need to consider replacing it in the near future.

Your roof has been harmed by water

This can occur from leaks in a roof or areas that are now exposed to the outside elements from shingles being blown off.

The insulation has mold developing on it

It is possible for mold to grow on your insulation without realizing it and it can come when the insulation is exposed to moisture for a prolonged period of time.

The insulation has holes in it

Insulation can become punctured by a variety of things including animals, extreme weather like storms, or even when the insulation was moved before it was installed.

The insulation is dirty

After years of use, insulation can get a build-up of dirt or dust that makes it less effective.

Your home experienced an extreme event such as a fire or weather

Anytime your home’s exterior is damaged and outside elements can get access to the inside of your home you should inspect all parts of your home for damage including the insulation.

Your home is older or you doubt the construction quality

Older homes can mean that the insulation that was used in the construction may either be past its lifespan or not up to current energy standards.  This can also be the case for homes that may have been built using cheap materials.

Your insulation is either batt insulation or loose-fill insulation

These types of insulation have their own issues.  Batt insulation will begin falling out after about 15 to 20 years of use.  Loose fill insulation has the issue of settling over time which can lead to air leaks.

Signs Your Insulation Needs Replaced

Even if you can’t see your insulation, there are a number of things that will happen inside your home, indicating your insulation needs replacing.

The temperature changes unevenly in your home

One of the clearest signs that your insulation is not functioning correctly is the variation in temperature throughout your home.  Your home should rise and fall in temperature relatively evenly throughout.  Homes that have insulation issues will see some rooms hot while others are cold.

You struggle to get your home to the right temperature and then keep it there

If you have noticed that it takes all day to get the temperature right in your home because it never stays at a constant temperature long-term it might be your insulation.

Your whole home feels drafty

Have you noticed drafts in your home during certain times? This is a clear indication that the insulation in your home is not working properly to block airflow from the outside.

Specific rooms in your home have drafts

Sometimes not all the insulation in your home might need replacing only certain areas.  Noticing a draft in some rooms and not others can indicate either the insulation in that area needs replacing or possibly that crawl spaces that were never insulated need insulation added.

Your energy bill is way too high

Did you get an energy bill that made your heart drop? Insulation that is not working properly means that your HVAC system will have to work harder to keep your home cool.

Occupants in your home get frequent allergies or sickness

Insulation that is older can be a spot for mold, allergens, and other types of bacteria to form and grow.  Sensitive members of your household or those that are directly exposed to old insulation can experience sicknesses related to it.

You have noticed leaks or other moisture issues

Any type of leak or moisture issues in your home should be a concern regarding not only your interior but also your insulation which is usually hidden behind your walls and floors.  When insulation is exposed to moisture over time it will deteriorate and not perform as intended.

You are having pest problems

Noticing an increase in pests within your home such as rats, mice, squirrels or insects can be a clear indicator that your insulation is compromised.  Pests usually make their way through your roof and down into your attic. If you have noticed small rodents or insects inside your home it can be a sign that somewhere, your insulation has a hole in it that they are making use of to access your home.

You have seen the insulation falling down or appearing wet

The most obvious sign that your insulation needs to be replaced is if you have physically seen it falling down or appearing wet.  Insulation should not be falling down, dripping, or breaking in any way.


New insulation can dramatically improve the energy efficiency of your home and reduce your energy bills.  It also decreases the stress on your HVAC unit and will improve the quality of air inside your home. Don’t wait until you are miserable to get your home’s insulation repaired.

10 Tips For Choosing The Right Insulation Company To Fit Your Needs

Choosing the right insulation company can really be challenging particularly if you don’t have a clear idea of what it is that you need out of your insulation. What may make things even worse is the fact that you won’t necessarily know if the installation was done right until something comes up. Especially if you don’t necessarily visit the areas that were insulated all that often. All these things make it imperative that you choose the right insulation company for the task at hand. How do you know though that you’ve picked a good option without having to wait for something bad to happen to realize that you’ve made a mistake? Here are a couple of tips to help you out.

Get A Company That Wants To Provide An Inspection Before Discussing Prices Further

Whenever you’re buying any service and the company that you’re talking to wants to spit out prices without really providing accurate inspections or accounting for the particular situation you may want to take a few steps back. Installing insulation is a process that is going to be unique to each situation, and a proper inspection before getting any work done is a great place to start. When a company just wants to see how much they can make off of you, you might be in the wrong spot.

Can They Layout The Challenges That Your Home Faces?

Is your crawl space particularly damp? Do you want to keep certain things in the attic that maybe shouldn’t necessarily go there? Different homes are going to feature a unique set of challenges for insulation installers. A good insulation company is going to be able to list all or most of these challenges before they begin working on a project. As a homeowner, this can be a great thing to help you realize where you’re standing and what can truly help you make things better.

The Options That You’re Given Should Make Sense

You don’t want to pay a premium price for fireproof insulation when your main issue is going to be humidity and moisture. There are times out there when companies in all industries will want to offer a premium product, knowing full well that getting that particular product may not make much of a difference to the final customer. It’s important to be smart about these types of things to avoid getting scammed.

They Know About The Different Options That Are On The Table

Here you may be forced to essentially walk a fine line. On one end you don’t want to be paying extra for a product that gives you the same benefits as the one that you can get at a regular price. Yet, you want to make sure that the company you’re working with understands the challenges that lie ahead for your property and therefore is truly providing solutions that fit your particular needs. If you really can’t see that clearly that could be one of those deal breakers where the best thing to do may be to look elsewhere.

There’s Enough Staff On Their End To Handle The Size Of The Project

You could be working with a great group of professionals, but if they just have the right amount of staff on hand to handle the project it’s going to slow things up. This can be a real problem particularly when the insulation installation is just part of a larger renovation project. What’s going to happen is that you’re going to be slowing everything up, that’s just not what you want. Be sure that the company you hire is capable of handling the sheer size of the project that you’re hiring them to help with.

Pointing You In The Right Direction For Extra Repairs

When you’re removing and reinstalling insulation there’s a good chance that more issues around the house are going to come up. In fact, there’s a chance that these issues are what caused your insulation to go bad. If the company you’re working with can provide a full repair service that’s a positive if they can help point you in the right direction to get someone who can help you with some of the other issues that came up that’s also a plus.

They Can Provide A Detailed Budget For The Project

Being clear about how much the tools and elements that they are going to use to complete the project is always going to be a positive sign for any company. This is going to allow you to evaluate any quotes that you get better since you can literally go out and check the price tags on different products to make sure that you’re getting a fair deal.

Not Shady About Where They Obtain Their Work Materials

This is kind of along the same lines as the last point. It goes back to this peace of mind that you probably want with regards to the type of materials that are being used in the project. You don’t want to feel like you’re being overcharged, and you want to know that what is being used are quality products that are going to last long. If the company wants to keep their cards too close to their chest about where they get products that could be a sign that something’s up. They could still get discounts from the manufacturer and pay less than you would if you try to buy from them so they’re not necessarily protecting their business by buying secrets about this.

A Warranty May Not Hurt

You want the company that you hire to get things right the first time around, that’s pretty much a given. That being said, if something does come up it’s not the worst thing in the world to know that you can fall back on the warranty for help.

If They Have A Decent Local Reputation That’s Not Harmful Either

We saved this to the end because we don’t feel that this is necessarily the end all be all. However, getting recommendations from friends and family about certain companies does carry weight. At least make sure that they don’t have a bad reputation.

Read This Before You Insulate Your Home

Insulating your home shouldn’t just be something that you check the boxes and complete the task. Obviously, there’s a purpose to insulation, and potentially more damming there are negative things that can happen when the process is not done properly. Picking the wrong type of insulation for specific parts of your home, for example, can’t put the integrity of the entire place at risk. There are types of insulation, spray foam in this case that is known for being highly flammable. This is something that has been addressed and some of the more recent versions of the material promise to be less so. Even though that seems to be the case, cheap spray foam insulation set up in a very hot attic could put your home at risk.

We don’t want to just sound the alarm and make it seem like setting up insulation properly is a matter of life or death. It very can be, that improper insulation setup has led to fires in homes with disastrous consequences, but these issues tend to be outliers. Luckily with very basic knowledge of insulation materials and the options that are out there on the market, you book a proper service from an insulation company in Virginia Beach and be sure that you’re not putting the integrity of your home at risk. There are a couple of things though that you may want to keep in mind.

Different Spots Around The House Maybe Better Suited For Different Types of Insulation   

We spoke about how flammable certain types of insulation are, now it’s time to talk about the other end of the spectrum. Fiberglass insulation is known for not being great at dealing with moisture issues. As is the case with spray foam insulation’s weakness there are a couple of ways to be able to tackle this. For example, with crawl spaces and areas that tend to get quite damp, maybe the answer is to do proper waterproofing work before insulating the area. That’s going to give you a bit more freedom when it comes to the type of insulation that you want to have installed. Although, we’d still recommend that you choose a particular type that can stack up well against the challenges that it’s going to face.

Going back to spray foam being flammable, the last thing that you want to do is put it in an attic with a really hot furnace, or store different types of chemicals in that attic that could spell disaster. What we are trying to get at is that there are different things that you can look into to protect your home. When you choose the right type of insulation for a specific area what you end up with is one less worry if you will. That peace of mind is certainly something that is worth having.    

How Long Is Insulation Typically Going To Last?

Under the ideal conditions, quality insulation could potentially last decades upon decades. As a homeowner, you potentially wouldn’t need to remove or redo your insulation in any way. The key to all of this though is that part about ideal conditions. We’ve already mentioned two of the main enemies of insulation, and we may want to add a third which are pests. Pests can go together with moisture issues and really tear into not only the insulation but the entire framework or foundation of a house even. What we would recommend that you do is to have the area inspected rather regularly to make sure that conditions have not changed, and therefore you may need to start thinking about your insulation once again.

Another thing that we would certainly recommend is that you prep areas accordingly before you think about setting up your insulation. There are home insulation companies out there for example that do waterproofing on crawl spaces before setting up the insulation. Whether you can kill two birds with one stone by hiring the same company to take care of the entire project or not it’s certainly important to make sure that you take care of the issues that may be plaguing the home first before you just come in and install the insulation. Even if moisture or pest issues are not necessarily evident you probably want to at least schedule an inspection. Once you get that green light you can go ahead with the insulation. 

Is There A Warranty With The Company That You’re Working With?

There are a couple of things to unpack here, for one you’re going to want to make sure that you’re getting quality materials installed in your home. It’s a good idea to ask any company that you want to get a budget from where they get their insulation and what that process looks like. There’s a chance that you’ll get a warranty from both the installer and the manufacturer if things go south. If you don’t know who the manufacturer is though that’s something that you could potentially be missing out on. Even a company that knows that they are selling short with the type of insulation that they are putting into your home doesn’t want it to fall apart quickly. If everyone is on the same page about what’s being put into your home and if that has a warranty it’s a better idea overall.   

Regular Inspections Are What’s Going To Make Insulation Last

This is something that we kind of alluded to in previous paragraphs, yet we just wanted to close out by saying that if you want your insulation to last, getting inspected regularly is the best way to go about things. Twice a year is probably ideal, once a year can be ok in certain parts. As we mentioned, what you’re really looking into is the integrity of the insulation itself, as well as the specific conditions within the home. A change in the conditions can quickly turn the tide and ruin perfectly good insulation. Things like leaks and major pest issues come to mind as things that can turn the tide. Hence the importance of those regular inspections.

What are the Benefits of Cleaning Air Ducts?

Air ducts are an essential part of your home. Thanks to the work of air ducts, the air in your home are constantly circulated from the cooling and heating systems. 

The circulated air fills your living environment, including the air you and your family breathe. As a result, dirty air ducts can lead to a host of issues. Here are five benefits of getting your air ducts cleaned professionally.

Here are some of the benefits of cleaning your air ducts.

Improved Air Flow Efficiency

As time goes by, your air ducts and registers will experience a build-up of things like dust and grime. This is entirely normal. However, this restricts the flow of air over time and progressively becomes worse. 

Your systems will have to work harder to meet your air circulation needs, but they won’t be as efficient. Having a clean air duct means your HVAC can do its job effectively and efficiently while being cost-effective all at the same time.

Nearly Eliminates all Unpleasant Odors

Homes house people, pets, and a lot of different smells. When you’re cleaning and using various cleaning products, painting, smoking, preparing food all contribute to stale odors in your air ducts.

Cleaning your air ducts means you’re eliminating stale odors and allowing your home to have a more fresh aroma. This is because the circulation of air would no longer contain lingering smells stuck in the HVAC. 

Breathing is Made Easier

So many people these days suffer from chronic allergies, breathing problems like asthma, or other respiratory issues. For them, HVAC systems not working correctly or efficiently enough can be life-threatening. 

On the other hand, even healthy people stand to lose in a situation where your air is not well circulated and clean. Everyone benefits from clean air ducts and HVAC systems overall. 

Dirty air being circulated can cause irritations, causing you to cough or sneeze uncontrollably and frequently. In the more serious of situations, it can cause bronchial and sinus congestion.

Reduction in Allergens and Irritants

Air ducts can become breeding grounds for microorganisms and harmful contaminants. People with allergies will suffer the most due to the mildew, pollen, bacteria, pet dander, mold spores, and various other toxins that live and grow in your dirty air ducts. 

If you are suffering from allergies, you’ll find that there will not be a single place in your home where you aren’t suffering because of the build-up in your air ducts. This can become a very uncomfortable and rather annoying situation to have to experience daily.

It’s advisable to regularly check and clean your air ducts to ensure that they’re not dirty to avoid making a bad situation worse in the case of someone with allergies or breathing difficulties.

Reduction in Toxins, Dirt, and Debris

Through no fault of your own, dirt, debris, and other toxins will find their way into your HVAC system. It’s going to happen and is nearly impossible to prevent. However, you can do something about it once it’s there. 

Leaving dirt, debris, toxins, etc., to exist and circulate through your air ducts can attract rodents or other creatures, just adding more problems that you’re going to hate discovering.

Prolonged HVAC Lifespan

When your HVAC works harder under the strain of dirty air ducts, it uses more resources, which can be catastrophic for your HVAC system as a whole. In addition, you may find, down the line, that some parts of your HVAC have been compromised. As a result, part of the system needs to be replaced, which can be expensive. 

At this point, you’re already added to your electricity bill and now need to replace pieces of your HVAC system. So, all in all, it adds up.

Properly cleaning and maintaining your HVAC system can prolong its lifespan. In addition, it is a much cheaper alternative than having to constantly replace air ducts. Beyond that, it’s better for your health, and that is something you shouldn’t be putting a price on. 

Saving Money on Electricity

As mentioned a few times already, when your HVAC system has to work twice as hard, if not harder, to effectively circulate air, then your energy bill will see an increase. This is only worsened in extreme weather situations. 

With the heavy build-up constraining the ducts, your HVAC is pushing air through tighter spaces. It was even estimated by Energy Star that 20% of air moved through duct systems is lost because of leaks and issues within the ducts. 

How Duct Cleaning Works

A lot of work goes into cleaning air ducts, and it is crucial to have at least a basic idea of what the process entails. Professionals know what they’re doing, and they usually do a better job than the average person would. In addition, having someone trained in cleaning ducts means you’re going to have peace of mind knowing someone is doing it right.

Professional duct cleaners will come and inspect your home and assess the following;

  • Air Ducts
  • Air Registers
  • Drain Pans
  • Fan (Which includes the housing and motor)
  • Diffusers
  • Grillers
  • Heating and Cooling Coils
  • Heat Exchangers
  • HVAC 

So much goes into a thorough inspection and cleaning that having someone who knows what they’re doing means nothing gets missed or skipped. This all leads to a better home environment overall. 

Now you know why cleaning your air ducts, and overall HVAC system is so important. There are so many negatives that come with poor upkeep of an HVAC system that can negatively affect your home, and more importantly, your health.
