How a Vapor Barrier Can Prevent Moisture in Your Crawl Space
If you have a crawl space in your home and you don’t have vapor barrier installed in it, you have probably noticed that moisture will build up in it from time to time. Crawl spaces are supposed to be vented properly to eliminate this, but you will still sense moisture after a hard rain or even just if you have simply had your home closed up for a few days. Insulation contractors can install vapor barrier to prevent moisture in your crawl space, and installing crawl space insulation near Seattle and Tacoma, WA, is a relatively quick job. Here’s how it works.
Check the Drainage Surrounding Your Home First
The first thing insulation contractors will do to prevent moisture from building up in your crawl space is take a look at your drainage situation outside. In order to keep moisture from getting under your home, your gutters and downspouts need to be in good working order. By directing water away from your home, you can stop it from getting under your house and causing issues in your crawlspace. At the very least, it will reduce the moisture you see and feel in your crawl space.
Cover the Dirt in the Crawl Space With Vapor Barrier
Once your insulation contractors have inspected your drainage, it’s time to get to work on installing the vapor barrier. For it to be effective, the plastic vapor barrier should be applied directly over the dirt in your crawl space and should run up each wall at least six inches. The vapor barrier should be fastened securely so that it doesn’t open up and allow any moisture to get through and affect your crawl space.
