We have the proven solutions you need for a dry, healthy crawl space

At TerraFirma, we use proven crawl space sealing solutions to transform your damp, nasty crawl space into a dry, clean, efficient, useable space.

Why seal your crawl space?

As warm air rises, cool air from the crawl space is drawn into your home's living areas. This process is called the stack effect, and is similar to the way a chimney works. Because of this and other factors, a lot of the air you breathe in your home actually comes from your crawl space. By installing a crawl space encapsulation system, we can reduce moisture that may be causing musty smells, mold, and structural damage in your crawl space.

Problems with an open, unsealed crawl space

Traditionally crawl spaces were built with vents that were believed to relieve excess moisture form the air and keep the crawl space dry. Experts now know that vents instead allow more variation in humidity, which creates more moisture. The pictured graph is from a Crawl Space Research project conducted by Advanced Energy, and shows how a closed crawl space can drastically improve moisture control in your crawl space.
