Insulating and Protecting a Crawl Space in Sutherland, VA

This homeowner in Sutherland, Virginia, was concerned about a variety of issues within their crawl space. Their insulation batts were damp with moisture and hanging down from the floor joists, while the porous foundation walls and open vents lining them were allowing the outside air and moisture to infiltrate the crawl space and affect the environment. We removed the fiberglass batts and installed a 20-mil vapor barrier over the dirt floor of the crawl space. We also blocked the open vents and used closed-cell spray foam to cover the foundation walls. This will help to seal off the crawl space from any outside influence.
