Crawl Space Encapsulation
Encapsulation turns a vented, damp crawl space into a clean, closed one. A heavy-duty vapor barrier covers the floor and climbs the walls, vents and gaps are sealed, seams are taped and the space is dried and monitored. The result is a drier home, fewer odors and a cleaner place to store things.

Common questions
Does encapsulation stop all moisture?
It blocks ground vapor and outside air. Liquid water needs drainage and a pump, which we add where needed.
Will it help the smell?
Often yes. Musty odors usually come from damp soil and mold, and sealing and drying address both.
How long does it take?
Many are done in a few days, depending on size and prep. We tell you before we start.
