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.
