Seal off your house from the moist damp earth with drainage matting, insulation and a vapor barrier. Breath better and improve life quality! Vapor barriers and insulation are a proven method for reducing moisture in a house. We also recommend sealing off any crawl space vents and installing a dehumidifier or Ez-Breathe Crawl Space Conditioner ventilation unit. The project manager will determine which suits the needs of the house appropriately.
