You shouldn’t just ask, “What should crawl space humidity be?” The answer to the perfect crawl space humidity doesn’t matter if you don’t know how to get there. There are many reasons you may have a crawl space humidity level that’s too high.
Instead of just trying to read a crawl space humidity chart, consider these fixes that can actually help you maintain the right humidity.
Crawl Space Encapsulation
This is the preferred method if you have a crawl space with a dirt floor. Unfortunately, there’s no way to stop a dirt floor from giving off moisture. You can only dry out the very top layer of soil; underneath, you’re always going to find moist soil.
That’s why you should consider crawl space encapsulation. With this method, a professional lays down a thick vapor barrier between the soil and the rest of the crawl space, ensuring that the moisture from the soil doesn’t actually impact the crawl space.
If you have a crawl space with a dirt floor, this is really the only way to make sure the moisture from the dirt floor doesn’t impact the rest of the crawl space. Contact a JES professional today to learn more about this option.
Close Crawl Space Vents
The concept of how to properly vent a crawl space has come up regularly ever since crawl spaces started. At the beginning of crawl space construction, people typically thought that a crawl space needed to “breathe,” which is why they installed crawl space vents.
However, because of the problems that occur when cool air meets warm air and vice versa, this may actually lead to a higher crawl space humidity level. You may actually end up with humidity problems because of your crawl space vents.
The only answer to the question of how to properly vent a crawl space is that you shouldn’t. Close the crawl space vents you have if possible, and contact a JES professional if you’re not sure how to do it.
Install a Dehumidifier
A dehumidifier can be a great option if you’re consistently having crawl space humidity problems. After all, that’s exactly what a dehumidifier is for.
Remember that some humidity in the air is good. You don’t want to completely dry out the air in your crawl space. You just want to keep the humidity level low enough that you won’t run into mold, wood rot, and other structural problems.
A JES expert can help you understand which dehumidifiers will work best for you. If you’re going to run your dehumidifier regularly, an expert can also suggest a great energy-efficient dehumidifier for your needs.
