Sealed Crawl Space

Ignoring crawl space conditions and the effects they may have on indoor air quality seems to be a thing of the past. People are more educated about how moisture enters their homes and the negative impact excess moisture can have on living conditions.

Since up to 50% of household air can flow up from your crawl space, it’s important to keep this typically unsightly space as clean and dry as possible. Since water vapor enters the crawl space from the ground (even through cement), many people are encapsulating their crawl space to keep the moisture out. Adding a crawl space vapor barrier and dehumidifier is widely accepted as the best way to improve indoor air quality and make energy improvements inside your home.

In this article, we’ll take a look at these solutions, provide tips for DIY crawl space encapsulation, and explain how to maintain a healthy humidity in your crawl space.

This water vapor barrier is most effective when it completely covers your crawl space, and sealing tape is used to connect the barrier pieces throughout your area.

Once your space is completely sealed, the final piece of the encapsulation puzzle is conditioning the air to maintain a healthy humidity level. The most common way to do this is by adding a dehumidifier to regulate your crawl space’s moisture level.

This barrier and dehumidifier combination protects the crawl space from excess moisture and all the problems that come along with it.
