What Is Crawl Space Encapsulation?

Crawl space encapsulation is a phrase you’ll see a lot on the JES website because it’s an important concept for a healthy crawl space. When you have an encapsulated crawl space, that means your crawl space doesn’t allow anything inside. The crawl space stays encapsulated, which means the outside world has no impact on it.

Typically, crawl space encapsulation requires that you close the crawl space with well-fitting crawl space doors, water vapor barriers, and crawl space vent covers if you have an open crawl space. This process gives you access to a healthier crawl space.
