Our team removed the less effective liner which was ripped and partially covering the crawlspace, this liner still allowed moisture and energy to escape into the space under the house and to the heating and cooling system and duct work. They then replaced it with our treated liner that prevent and protects against mold and other moisture caused issues. The sprayfoam division then insulated the crawl space, creating an air tight seal throughout the space, preventing the escape of heat/cool air.
