Crawl Space Moisture in Richmond, VA

This Richmond, VA homeowner contacted us because they noticed moisture issues in their crawl space that they wanted to be addressed. At our inspection, we found microbial growth on the floor joists, no vapor barrier covering the ground, and falling, damaged insulation. 

Once the homeowner's belongings were removed, we cleaned all of the debris out of the crawl space and treated the microbial growth. We then sealed all the vents and air sealed the sill plate and all penetrations through the foundation walls to the outside. Next, our team rolled out a heavy-duty vapor barrier called CleanSpace, it was attached to the foundation walls, wrapped and sealed around all piers, and overlapped and sealed at all seams to seal the crawl space off from the earth's moisture. Now, the space is ready to be insulated with closed-cell spray foam on the foundation walls and in the rim band. Then a dehumidifier will be installed to control the relative humidity. 

Keeping air carrying moisture out and controlling the relative humidity in the space will help to prevent future moisture damage in the crawl space. It also creates a clean dry storage space for the homeowners and will help to keep their floors warmer in the winter and can even reduce energy bills.
