This crawl space had falling insulation, mold/mildew, efflorescence from moisture and condensation, and a failing vapor barrier. We installed the CleanSpace Encapsulation System with closed cell spray foam insulation on the crawl space walls, sealed the rim and band and sill plate, and installed a SantaFe Dehumidifier, sealing the home off from the earth and controlling the relative humidity to help make this Williamsburg home more comfortable and energy-efficient.
