Best Dehumidifers

For those of you that are encapsulating a crawl space, wanting to improve air flow in the crawl space or considering putting something in place, the long list of possibilities can be a daunting task. Face it, there’s a lot to worry about, such a job can get expensive and then there’s the actual products itself you have to worry about. No matter what stage you’re at, we’re going to help you through the process right now, start to finish.

Crawl Space Encapsulation

 First, if you truly want to protect your crawl space, encapsulating the crawl space is the way to go. Ask me once, ask me a thousand times and it will be the same. If you’re going to encapsulate your crawl space, make sure it’s done right the first time. Then you don’t have to worry about it again. Go cheap or do it wrong, it can become a headache. Period.

Depending on the crawl space itself, you will likely be using a 20 mil vapor barrier or a 12 mil vapor barrier for the crawl space floor. That’s probably the safest bet, although you can go 12 mil, 8 mil or 6 mil on the foundation walls. The more traffic in the crawl space and storage, the larger crawl space liner you’ll need. Vapor barrier and liner referring to the same thing.
