Moisture: Your Crawl Space’s Greatest Enemy

The reason vapor barriers are such an important part of a closed crawl space is that moisture is basically your crawl space’s greatest enemy. Moisture is great at finding its way into places it doesn’t belong, and you need to be sure it can’t get into your crawl space.

How can you keep moisture out of your crawl space? These methods will help the most. 

An Entirely Closed Crawl Space

When you say, “closed crawl space,” you should mean closed crawl space. The most important things to check here are a vapor barrier, crawl space vents, and the door to the crawl space.

Your vapor barrier should be a 20-mil CrawlSeal vapor barrier because it’ll provide you the most protection. You should seal any open crawl space vents and make sure the door to the crawl space has an ultra-tight seal that doesn’t allow moisture or water in.

When you take these tips, you’ll end up with a crawl space that doesn’t allow moisture inside. That’s the first step to a dry crawl space. 

Sump Pump Installation

Even if you’re not allowing moisture in from the ground, there are still instances in which you may experience flooding. For example, if there’s a plumbing leak in the crawl space or if your home has a hard time with water drainage, you may discover more water even after encapsulation.

This is where a sump pump comes in. This pump can help you keep your crawl space dry even if there are drainage problems because it uses a motor to pump the water out of the area.

You shouldn’t install a sump pump until you’ve gotten rid of as much water as possible on your own. This should be an ongoing benefit, not your only focus. A JES expert can let you know whether you need a sump pump or some other kind of fix. 

Add a Dehumidifier

Even if you’ve done all this right, there’s still a chance that the general moisture levels in your area may be too high for a healthy crawl space. That’s where a dehumidifier comes in.

Depending on your area, you may need a dehumidifier in your crawl space occasionally, regularly, or all the time. This dehumidifier can keep it nice and dry in your crawl space. It’s a great option if you’ve fixed water leaks and other water issues, but you’re still seeing high levels of humidity.

Especially if you’re going to run it all the time, you need to make sure you’re using an energy-efficient dehumidifier so you don’t run your energy bill up. This is a decision that a JES expert can help you make.
