Crawlspace Encapsulation - Upstate SC
A damp crawlspace shows up in the rest of the house: musty smells, sticky floors, sagging insulation and wood that starts to rot. I seal the crawlspace off from the ground and the humid outside air, keep it dry with a dehumidifier, deal with any water coming in, and repair the insulation and framing the moisture has already damaged, all under one contract, licensed and personally overseen.

What is crawlspace encapsulation?
Encapsulation closes the crawlspace off from the ground and the outside air. A heavy vapor barrier covers the ground and runs up the foundation walls with the seams taped and the piers wrapped, the foundation vents and access door are sealed, and a dehumidifier keeps the air dry. The result is a crawlspace that stays dry instead of pulling in damp Upstate SC air all summer.
How do I know if my crawlspace needs to be encapsulated?
Common signs are a musty smell in the house, floors that feel soft or bouncy, insulation hanging down or lying on the ground, condensation or mold on the joists, standing water after rain, and high humidity indoors. We inspect the crawlspace and tell you what we find before recommending anything.
How much does crawlspace encapsulation cost?
Every crawlspace is priced to its own inspection, so we quote each job individually rather than publishing a range. The size of the crawlspace, its height, whether water is getting in, and how much insulation and wood has to be replaced all change the price. The consultation and estimate are free.
Do you fix water problems and rotted wood before encapsulating?
Yes, and they come first. Where water gets in we install interior drainage and a sump pump, and as a licensed general contractor we repair rotted joists and sills and treat mold. Encapsulating over an active leak or damaged framing only hides the problem.

Crawlspace Inspection
We go under the house and check for standing water, moisture in the framing, insulation condition, mold and any rot, then price the work to what we actually find, not a one-size package.

Repair and Encapsulate
Water problems and damaged wood are fixed first, then the crawlspace is sealed, insulated and dried out with a dehumidifier, so the encapsulation is not covering up a problem.

Why does an encapsulated crawlspace need a dehumidifier?
Sealing the vents stops humid outside air from coming in, but some moisture still enters from the house, the foundation and the ground. A dehumidifier drained to a sump or to the outside removes it and keeps the crawlspace dry year-round, which protects the framing and the insulation.
