Common Questions

Why is crawlspace work especially important in Charleston?

Charleston's high water table, humidity, and termite pressure make crawlspaces one of the most vulnerable parts of any home in the Lowcountry. Moisture in the crawlspace leads to rot, mold, and structural damage — and termites love warm, damp wood. Encapsulation and regular inspection are essential.

What is crawlspace encapsulation?

Encapsulation seals the crawlspace from ground moisture using heavy-duty vapor barriers on the floor and walls, turning it into a semi-conditioned space. This dramatically reduces humidity, prevents mold, and keeps wood dry and structurally sound.

Can you fix termite or water damage in my crawlspace?

Yes — this is one of our most common jobs. We remove and replace damaged joists, beams, and subfloor material, treat the area, and encapsulate to prevent future moisture problems.
