Photo Album: Cold Floors Over a Crawl Space in Falls Church, VA

Homeowners in Falls Church, VA had cold floors over their crawl space. This crawl space was not sealed off from the outside and was way under insulated. The existing crawl space insulation under the floor wasn't enough to prevent the floor above from cooling down, and the colder temperatures were forcing the heating system to work harder. The Comfenergy experts had a solution to this. Crawl space insulation and encapsulation did the trick. Once the system was in place, these homeowners noticed dramatically warmer floors above the crawl space. Now they won't lose heat through ducts or pipes in the crawl space either, which will save money on their heating costs.

First Steps in Crawl Space Encapsulation

To repair and insulate this crawlspace, we first removed the old insulation. To keep moisture from entering the space, we installed drainage matting beneath TerraBlock foam insulation on the floors, and the CleanSpace vapor barrier above it.

Spray Foam Installed on the Walls

On the walls, we used closed cell spray foam. It's perfect for a crawlspace environment! Closed cell foam cures dense and hard, and it forms an effective barrier against both moisture and air.

EverLast Crawl Space Door

Properly sealing your crawl space entryway is a crucial step to keeping cold air and drafts out of your home. Typical crawl space doors rust, rot, and fall apart. The EverLast Crawl Space Door does none of these things. The crawl space door creates an airtight, waterproof seal, and because it is inorganic, it does not support mold growth.
