Crawl Space Insulation
Cold floors and musty air usually start under the house. We seal and encapsulate crawl spaces with closed-cell foam, blocking ground moisture, rim-joist drafts, and the damp air that works its way up into the living space, on homes and commercial buildings alike.
Why homeowners choose it
- Closed-cell foam stands up to ground moisture
- Warmer floors and steadier temperatures above
- Shuts down mold, pests, and musty air at the source

Questions homeowners ask
What does crawl space encapsulation involve?
We seal the crawl space walls and rim joists with closed-cell spray foam, blocking ground moisture, rim-joist drafts and the damp air that works its way up into the living space. The result is warmer floors, steadier temperatures above and no musty smell.
Why are the floors above my crawl space cold?
A vented crawl space fills with outside air, and in winter that air sits directly under the floor. Sealing the vents, the walls and the rim joist stops it. Cold floors and musty air usually start under the house, and that is where we fix them.
Can a dirt-floor crawl space be sealed?
Yes. Dirt-floor and vented crawl spaces are where encapsulation does the most good. Closed-cell foam stands up to the ground moisture that makes other insulation fail there.
Where we do this
Based on Federal Road in Brookfield, working across western Connecticut and the New York border.
