Did you know that your home’s crawl space vapor barrier is designed to block out moisture? It’s so important because when moisture is present in your crawl space, mold, dust mites and insects thrive. Let’s take a closer look at what your crawl space’s vapor barrier does:


1. Keeps moisture out

A good vapor barrier will seal your crawl space and keep moisture out. Why does this matter? When excess moisture enters your crawl space, it becomes a breeding ground for things you don’t want in your home — mold, dust mites, insects and other pests. And, because the crawl space tends to be “out of sight, out of mind,” you might not even know that all of this is occurring underneath your house.

2. Controls air quality

It’s estimated that almost half of the air on the first floor of a house comes from its crawl space. If your crawl space lacks a quality vapor barrier, then mold spores, pest droppings and more could be entering the air you and your family breathe.

3. Conditions your crawl space

With a properly functioning vapor barrier, your crawl space becomes a somewhat conditioned area. That’s because the vapor barrier prevents air from passing through. It can help keep your crawl space at a temperature near that of the rest of your home. This, in turn, can keep energy costs down.
