How Can I Fix High Indoor Humidity?

The good news is that there are plenty of ways you can fix your high indoor humidity. When you contact a crawl space repair expert, these are the typical steps the expert will go through to help you fix the crawl space humidity problems.  

Remove Standing Water 

The first step to fixing your high indoor humidity levels is to make sure you’ve removed any and all standing water in the crawl space. If you have standing water, the water will just continue to evaporate into the air, causing high levels of crawl space and indoor humidity no matter what other steps you take to avoid the creation of humidity in the area. 

There are a number of ways to remove standing water from the crawl space. An interior drainage system and a sump pump may be a need, especially if you have recurring issues with standing water that may need a recurring fix. Standing water is a problem you shouldn’t try to fix by yourself. Instead, you should consult a crawl space repair expert to handle the water itself and any secondary problems arising from it. 

Close Crawl Space Vents  

Does your crawl space have open crawl space vents? Most homes with a crawl space have crawl space vents because of the widespread belief that these were necessary. Even today, as more crawl space experts are realizing their mistake and starting to recommend against crawl space vents, many residential codes consider vented crawl spaces the default. 

The good news is that it’s actually relatively easy to close your crawl space vents. JES offers crawl space vent covers that you can use to close the crawl space off entirely. This is one of the best ways for you to make sure you’re not letting in excess crawl space moisture, because crawl space vents are responsible for all sorts of issues in your crawl space.  

Install Vapor Barrier System 

A vapor barrier system is an incredibly important part of your crawl space. This is what many people think of when they think of “crawl space encapsulation.” You need to have a crawl space vapor barrier because it’s the piece of the puzzle that ensures moisture doesn’t come up through your dirt crawl space into the rest of your home. 

However, although you do need a crawl space vapor barrier of some kind, it’s important that you install a high-quality crawl space vapor barrier rather than just springing for the cheapest vapor barrier available. JES uses the CrawlSeal™ 20-mil crawl space vapor barrier. This is over three times thicker than the minimum requirement that many crawl space residential codes mandate. 

Add Dehumidifier  

In some cases, it may be important to add a dehumidifier into your crawl space. Although it’s true that this might be an important part of your crawl space encapsulation process, there’s a reason this step goes at the very end. You should never begin your quest to remove your crawl space moisture by installing a dehumidifier because it won’t work if you just put in a dehumidifier. 

You need to go through the process of crawl space encapsulation before you can add a dehumidifier. Once you’ve covered the crawl space vents, added a crawl space vapor barrier, and ensured standing water is no longer a problem, then you can use a dehumidifier to make sure the humidity levels stay stable and healthy. However, if you haven’t done all of these steps, don’t bother with a dehumidifier, because it won’t fix the actual problem you’re experiencing.
