Approximately 50% of the air you breathe in your home comes from your crawl space. Unsealed, vented crawl spaces create the perfect conditions for mold/mildew to grow and pests and rodents to live. It also results in cold floors in the winter and energy loss. Encapsulating your crawl space with the CleanSpace Encapsulation System allows you to control the relative humidity in your crawl space and help prevent mold from growing and makes your home more comfortable.
