Crawl Space Vapor Barrier – Why?
A damp crawl space is a breeding ground for mold, mildew, wood-rotting fungus, insects, and rodents, which is why it’s vital to encapsulate your crawl space using a proper vapor barrier. This picture shows a thin, plastic vapor barrier, which was easily torn. The goal and objective of encapsulation is to protect or isolate your home from the water or moisture vapors that come from the earth. This, in essence, also protects the floor joists in your crawl space from mold and the air quality in your home.

Crawl Space Vapor Barrier FAQs
A crawl space vapor barrier is highly encouraged if you have a dirt crawl space. Here's everything you need to know about your crawl space vapor barrier.
A vapor barrier doesn’t by its nature prevent mold; that’s something you have to pursue with a number of different tactics. However, because a vapor barrier helps to reduce humidity in your crawl space by blocking off moisture from the earth, it can help you reduce the possibility for mold in the future. Some vapor barrier materials, like CrawlSeal™, have been treated to resist mold, however.
People have a variety of opinions on the preferred thickness of a vapor barrier for the crawl space. The IRC mandates at least a 6–mil vapor barrier, but you certainly shouldn’t settle for the bare minimum. If you want the maximum coverage that makes sense for a crawl space, consider something like the CrawlSeal™ 20–mil vapor barrier.
When you consult with a crawl space repair expert, the expert will give you all the information you need to know about how they’ll install the vapor barrier. Typically, the vapor barrier goes across the entire floor, then also goes up the walls. It also can be wrapped around columns and concrete block supports.
Finding the best vapor barrier for a crawl space isn’t necessarily a super direct process. There are many potential answers to this very difficult question. A JES crawl space repair expert will be able to assess your crawl space through an inspection and give you a recommendation for your crawl space vapor barrier needs.
