Sealing the Crawl Space
Recently, the U.S. Department of Energy funded a study to determine
the relative performance of sealed crawl spaces versus vented crawl
spaces. The study found that a sealed and conditioned crawl space has
many advantages over a vented crawl space, including lower energy
consumption, lower moisture content in the home’s wood, lower humidity,
and reduced fungus growth. Crawl space sealing work is typically
performed by waterproofing companies.
