Expert Crawlspace Encapsulation in Franklin, TN

Crawlspace encapsulation seals your crawlspace from ground moisture. We install a thick vapor barrier over the dirt floor, seal the foundation vents, and add a dehumidifier to control humidity year-round. Franklin sits in a humid climate where moisture rises up through the ground constantly. An open crawlspace lets that moisture into your home — into your insulation, your floor joists, your HVAC ducts. Over time, that creates mold growth, rots wood, and makes your floors feel damp or smell musty.

The encapsulation process starts with cleaning out everything that's already damaged. We pull out wet insulation, remove old plastic sheeting that isn't doing anything, and clear out debris. Then we install a heavy-duty vapor barrier, usually 12-20 mil thick, that covers the entire floor and goes partway up the walls. We seal the seams, close off the vents, and install a commercial dehumidifier that keeps the space dry.

Most homes in Williamson County weren't built with encapsulated crawlspaces. Older homes in downtown Franklin or the historic neighborhoods have open dirt crawlspaces that let moisture come right up. Once the space is sealed, your floor joists stay dry, mold can't grow, and the air that moves up into your living space is cleaner. Your HVAC system works better because it's not fighting moisture from below.
