Most homeowners tend to ignore their crawl spaces. Not only can this result in costly mold removal services and sometimes even repair work to the crawl space structure, but it can also have serious health consequences for the house occupants.

Here we will answer some common questions homeowners may have about purchasing and using a crawl space dehumidifier, and we will also be reviewing Mounto, AprilAir, and AlorAir dehumidifiers.

How much does a crawl space dehumidifier cost?

The cost of a crawl space dehumidifier depends on numerous things, such as the brand, its features, and the size of the area it can cover.

However, expect to pay between $700 to $1,000 for a quality crawl space dehumidifier. It’s a small price to pay, considering that the minimum cost for professional crawl space mold removal is $500, while repair work from mold damage to the structure can go as high as $30,000.


Does my crawl space need to be encapsulated for me to use a dehumidifier down there?

Not necessarily. Of course, you will get optimal performance from your dehumidifier in an encapsulated crawl space, but as long as the crawl space is sufficiently sealed, then it’s okay.

Walk around your house and inspect it for cracks or openings near the ground level. If you find any, then seal them off. Not only will this help prevent water and all sorts of animals from entering your crawl space, but it will also seal it off sufficiently for the dehumidifier to function as it should.


Can I use a regular dehumidifier in a crawl space?

Yes, you can. Although it’s crucial that it is powerful enough to cover the entire area of your crawl space and it has to be small enough to fit inside tight spaces comfortably.

Also, it must have a water outlet instead of only a bucket removal system, because the last thing you want is to go down there once or multiple times a day to manually remove buckets of water.


Where to place a dehumidifier in the crawl space?

For best results, place the dehumidifier somewhere around the center of the crawl space with no obstructions near it.
