If you live in a classic home in Hilton Village or a newer development near City Center, your attic is likely the biggest “money leak” in your house.
In 2026, building standards for the Peninsula have reached a new peak: R-60 is the new R-38. If you haven’t updated your attic in the last five years, you are likely under-insulated for the Virginia heat. Here is everything you need to know about 2026 pricing, the new standards, and how to get your attic working for you.
Why the “R-60” Standard Matters in Newport News
Newport News sits in a high-humidity coastal zone. Old standards suggested 10–12 inches of insulation, but 2026 efficiency goals for Virginia homes now recommend 18 to 20 inches of blown-in fiberglass (R-60).
At this depth, your attic acts as a true shield, keeping that heavy Tidewater humidity out of your living space and allowing your HVAC to run 15–20% less during the peak of summer.
Blown-In Fiberglass: The Seamless Shield
We focus on blown-in fiberglass because it is the most effective way to eliminate “thermal bridging.” Unlike fiberglass batts (rolls) that leave gaps around wires, pipes, and joists, blown-in material is applied pneumatically to create a solid, gap-free blanket that covers every square inch of your attic floor.
2026 Pricing Guide for Newport News
Pricing depends on whether you are simply adding to your current insulation or starting from scratch with a clean slate.
1. The “Top-Off” (Adding to existing dry insulation)
- Best for: Attics with clean, dry insulation that is simply too thin.
- Cost: $1.60 – $2.80 per square foot.
- Project Average (1,000 sq. ft.): $1,600 – $2,800.
2. Full Removal + “PestGuard” Fiberglass Installation
In many local homes, insulation has become a nesting ground for pests or has been flattened by old roof leaks. In these cases, we recommend a total system reset. We remove the old material and install PestGuard Fiberglass Insulation.
PestGuard is a premium, loose-fill fiberglass treated with specialized minerals. It is lethal to insects like cockroaches, silverfish, and earwigs, and it prevents the growth of wood-destroying fungi, all while being perfectly safe for your family and pets.
- Insulation Removal & HEPA Vacuuming: $1.50 – $2.50 per sq. ft.
- PestGuard Fiberglass Install (to R-60): $3.00 – $4.50 per sq. ft.
- TOTAL SYSTEM COST: $4.50 – $7.00 per square foot.
- Total Project Average (1,000 sq. ft.): $4,500 – $7,000.
FAQ: Newport News Home Insulation
1. Does fiberglass work well with the high humidity on the Peninsula?
Yes. Unlike cellulose, modern blown-in fiberglass is non-absorbent. It doesn’t hold onto moisture from the air, which prevents it from becoming heavy, “settling,” or losing its R-value over time.
2. Can I just put new insulation over my old insulation?
Only if the old stuff is dry and clean. If there are signs of rodent droppings or previous mold, “capping” it with new insulation actually traps those contaminants and can degrade your indoor air quality. A clean removal is always the best long-term move for your health.
3. Will PestGuard insulation kill mice or squirrels?
No. PestGuard is designed to control invertebrates (insects) and fungi. While it makes the attic far less attractive for nesting, it is not a rodenticide. For active rodent issues, we recommend a full removal and sanitization of the attic before the new PestGuard is installed.
4. How do I qualify for the $1,200 Federal Tax Credit?
The 2026 Federal 25C credit allows you to claim 30% of the material costs for insulation and air sealing, capped at $1,200 per year. We provide the specific “Manufacturer’s Certification Statement” you need for your tax filing.
5. Are there local rebates specifically for Newport News?
Yes. Newport News residents served by Dominion Energy can often access state-level rebates of up to $1,600 for weatherization. These are usually based on the total energy savings achieved by your upgrade, making the move to R-60 even more profitable.
