How to Fix Crawl Space Humidity Problems

The best way to fix your humidity problems is to make sure you’re at the right crawl space humidity level. The thing is, many people don’t actually know what the best humidity level is, which can lead to a lot of concerns. What can you do to craft a humidity level that’s right for you? 

Take Care of Standing Water  

The first step to fixing crawl space humidity is to take care of any standing water that might be in your crawl space. Unfortunately, standing water is a problem that some crawl spaces have. If you have standing water in your crawl space, it can evaporate and turn into crawl space moisture.

This is why you need to handle standing water first. Standing water can come from condensation, from plumbing leaks, from open crawl space vents, and a variety of other reasons. Once you isolate the cause of the problem, you can stop the initial problem, then pump out any standing water that’s still left in the crawl space.

Close Crawl Space Vents and Doors  

Next, you need to make sure crawl space vents and doors don’t allow in any air or water. Crawl space vents tend to be the biggest problem here because builders intend for them to allow in air, but if you have an ill-fitting crawl space door that opens to the outside, that can also allow in air, water, pests, and anything else you don’t want.

There are easy ways to close crawl space vents that don’t require you to do anything extremely significant. A JES crawl space repair expert can give you more information on sealing crawl space vents. If you’re having an issue with your crawl space door or you’ve never thought about your crawl space door before, you may also want to put some time and money into fixing it.

Put Down a Vapor Barrier  

Your next step should be to put down a vapor barrier. A vapor barrier does exactly what it sounds like: It separates your crawl space from anything that could cause water vapor to accumulate in the crawl space. An expert can install a vapor barrier in a dirt crawl space to make sure the moisture from the dirt doesn’t go into the air, causing extremely high levels of humidity.

However, this isn’t the only thing a vapor barrier does. It also forms a simple, clean barrier for any experts who need to inspect your crawl space for any reason. Make sure you invest in a high-quality vapor barrier instead of just opting for the cheapest one. JES only uses the 20-mil CrawlSeal™ vapor barrier because it ensures the highest levels of safety and security.

Install a Dehumidifier  

Even after you’ve encapsulated your crawl space, you might still have some humidity problems. For example, you may live in a high-humidity area, which can lead to a crawl space that’s more humid than you might like. An energy-efficient dehumidifier may be the right answer to these problems. When you use a JES dehumidifier, you can keep your crawl space at the right humidity level no matter what the humidity level is right now.

Dehumidifiers should never be your first step because you should always try to tackle the cause of the humidity concerns at their root. However, that doesn’t mean dehumidifiers are useless. The truth is exactly the opposite. It’s much better for you to choose a dehumidifier if you’ve already handled the cause of many of your humidity concerns, but there are certain issues you aren’t able to handle that only a dehumidifier can really help with.
