Crawl Space Insulation

Insulate the Walls, Not Just the Floor

For decades, builders stapled fiberglass batts between floor joists — and in a humid climate like Clarksville's, those batts absorb moisture, sag, fall down, and become a home for pests. The modern, far more effective approach is to insulate the foundation walls of a sealed crawl space instead. This keeps the entire space closer to your home's temperature and eliminates the cold, drafty floors that fiberglass never really solved.

Our Insulation Options

We recommend and install the insulation that fits your home and budget:

• Closed-cell spray foam — the premium choice, adding an air seal and vapor barrier in one application with excellent R-value.
• Rigid foam board — a cost-effective, moisture-resistant option for insulating foundation walls.
• Removal of old, wet fiberglass that's no longer doing its job and may be holding moisture.

Comfort and Savings You Can Feel

Insulating a sealed crawl space typically pays off in two ways Clarksville homeowners notice right away: warmer floors during our cold snaps and a smaller, steadier heating and cooling bill. Because your HVAC no longer has to fight temperature swings coming from below, it runs less and lasts longer. Insulation works best as part of a sealed, encapsulated crawl space — we'll tell you honestly whether your space is ready for it.

Done Right, Backed for Years

We install crawl space insulation with the same care as our encapsulation work — clean, complete, and warranted. Your free inspection includes a straightforward recommendation on whether spray foam or rigid board makes more sense for your home.
