Crawl Space Encapsulation in Greensboro

Turn a damp, vented crawl space into a dry, closed one

Encapsulation seals the crawl space from outside air and ground moisture, then controls humidity so the space stays dry year-round.

What a full encapsulation includes

• Moisture fixes first: gutters, grading, plumbing leaks, and interior drainage where water enters
• Reinforced liner (often 10 to 20 mil) over the floor and up the foundation walls, with sealed, taped seams
• Sealed vents and access door
• Rim joist sealing or insulation, often with closed-cell foam or rigid board
• Humidity control: a dedicated crawl space dehumidifier or conditioned supply air
• Termite inspection gap at the top of the wall liner, per common practice

What to watch for in quotes

1. Is the liner thickness and brand specified?
2. Is the dehumidifier sized for your space, and who services it?
3. Are drainage and structural repairs itemized separately?
4. What's the warranty on the liner and equipment?

Order matters

Fix water entry, then repairs to framing, then encapsulation. Sealing up a crawl space with an active leak or rotted joists just hides the problem.
