Crawl Space Repair and Encapsulation

Encapsulation seals the crawl space from the ground and outside air so it behaves like part of the conditioned house instead of a vented outdoor space. Liner runs across the soil, up the piers, and up the foundation walls, and every seam is sealed.

Done correctly, encapsulation lowers humidity under the house, stops condensation on ductwork, and makes the floors above noticeably less drafty in winter.

A vapor barrier is the lighter-duty option: liner laid over the soil to slow ground moisture, without the full air-sealing of an encapsulation system.

It is a real improvement over bare dirt, and it is the right call for some budgets and some crawl spaces. It is not equivalent to encapsulation, and we will tell you plainly which one your crawl space actually needs.

Sealing the crawl space removes the biggest moisture source, but the space still needs a way to shed residual humidity — especially in a wet spring.

We install crawl-space-rated dehumidifiers with a condensate line routed to daylight or a sump, sized to the cubic footage rather than to a generic default.

When a floor dips toward the middle of the house, the support system under it has usually settled, rotted, or was under-built to begin with.

We measure the floor, find the low points, and add or replace support so the load path reaches solid bearing again — then lift gradually where lifting is appropriate.
