What a vapor barrier does

A vapor barrier is a thick, durable liner laid across the crawl space floor, and run up the walls in a full system, that blocks moisture from wicking up out of the soil. In Kansas City's clay soil, that ground moisture is the single biggest source of crawl space humidity, so stopping it at the floor is the foundation of any dry crawl space.

More than just plastic

Effective moisture control is a system. Along with the barrier we seal the vents that let humid outside air in, address any drainage or standing water, and add a dehumidifier where needed to manage the remaining humidity. A liner alone, without sealing and conditioning, only does part of the job.

The first step or the full fix

A vapor barrier is the heart of full encapsulation, and for some homes a barrier with vent sealing is enough to turn the corner. We assess your crawl space and recommend the level of moisture control that actually solves your problem, not more than you need.

Frequently Asked Questions

Is a vapor barrier the same as encapsulation?
A vapor barrier is the core component of encapsulation. Full encapsulation adds sealing the vents, running the barrier up the walls, and conditioning the space with a dehumidifier. We help you decide how far to take it.
How thick should a crawl space vapor barrier be?
A durable encapsulation-grade liner is far thicker and tougher than the thin plastic sometimes found in crawl spaces. A proper barrier resists tears and lasts, which is why we use heavy-duty material.
Can a vapor barrier alone fix my moisture problem?
Sometimes. For a mildly damp space, a quality barrier plus sealing the vents can be enough. For persistent humidity or mold, a dehumidifier and full encapsulation are usually needed. We assess and tell you honestly.
