If you are closing crawlspaces, it’s important to know that insulating or encapsulating a crawlspace usually won’t be truly effective until the area is properly dehumidified. Homes with basements or crawlspaces in particular need dehumidification to prevent mold from growing in the floor joists and subfloors. Crawlspace Depot offers dehumidifiers that are small enough to fit in crawlspaces easily, but with the power and high capacity to remove as much as 90 pints of water per day from areas as big as 3,000 square feet. Because these dehumidifiers are designed for use in crawlspaces, they operate well at low temperatures. Some models even offer smartphone Wi-Fi controls, making daily monitoring and operation simple.
