The crawlspace is the area in your home that is located between the floor and the ground. Crawlspace encapsulation is the process of sealing up this area using insulation. It is one of the best things you can do to improve the quality of air inside your home.  At WNY Spray Foam, we take concrete steps in getting your crawlspace sealed depending on the construction of your home. Our team uses a heavy-duty liner that is sealed to the foundation, foam any crack above the foundation wall, seal all outside ventilation vents, build air-sealed custom access doors and use waterproof tape on all liner seams.
