Crawl Space Insulation in Henrico, VA

This Henrico, VA client contacted us because they wanted to address the insulation in their crawl space. Moisture had caused damage to the fiberglass insulation and it was sagging and falling to the ground. The unsealed, vented crawl space was allowing moisture to flood in and cause damage to the insulation as well as mold and mildew growth. 

The homeowner wanted to not only reinsulate the crawl space, but they also didn't want to do it again in a few years. After reviewing their options, they opted to encapsulate the space. The crawl space was cleaned out and treated with an antimicrobial. Then, a new vapor barrier is installed sealing the crawl space off from the earth's moisture. Our team then air seals the space by blocking and sealing all vents and sealing any penetrations through the foundation wall to the outside. 

Next closed-cell spray foam is applied to the foundation walls and rim band. A SaniDry Sedona dehumidifier is installed to control the relative humidity and help prevent future microbial growth. Finally, an interior friction-fit door is installed to air seal and insulate behind the exterior door, and an Everlast exterior crawl space door is installed on the outside.
