Crawl Space Vapor Barrier


Tens of millions of homes have crawl spaces under them instead of a traditional basement. These crawl spaces are just as important as a basement, and they can be a source of problems if not maintained properly. You often have HVAC ducts there, wiring perhaps, as well as other things, and crawl spaces can even be used as storage areas. The downside to crawl spaces is that they can be dank, musty places that you don't want to go unless absolutely necessary. This is where the team at comes in, as they can help you with a crawl space vapor barrier for your home.

Crawl Space Vapor Barriers Keep Moisture Out

Any place that has moisture has the possibility for mold and/or mildew. A moist place can also attract pests. Either of these can be problematic if located in a crawl space. Additionally, moisture can affect the air quality in your home, especially on the first floor directly above the crawl space. The air can feel more humid and maybe unhealthy from the possible mold and mildew.

Adding a crawl space vapor barrier to reduce or eliminate the moisture issue. A vapor barrier, by its nature, resists the passage of air. By stopping air movement from the ground, it can also turn your crawlspace into a self-conditioned space - one that is close to the temperature of the living spaces above. A vapor/air barrier can also slow or block most of the movement of harmful gases, such as radon, from the soil.
