Crawl Space Dehumidifier Installation

Water always follows the path of least resistance, which can sometimes lead straight into your crawl space, causing serious issues for your home.

As the trusted crawl space repair experts in Virginia, Maryland, and Washington, D.C., homeowners depend on JES Foundation Repair to protect their homes. Discover how installing a crawl space dehumidifier will improve your home and provide long-term value.

What is a Crawl Space Dehumidifier? 

Crawl space dehumidifiers remove extra moisture from crawl spaces, which become damp because of wet soil or humid weather. Too much moisture can cause mold and wood rot, which can damage your home’s structure.

The dehumidifier pulls in moist air, cools it down, and turns the moisture into water droplets. These droplets are collected in a tank inside the dehumidifier and then drained away.

To keep the crawl space dry, the dehumidifier needs to run often. Most dehumidifiers have a hygrometer, which measures the moisture level in the air and turns the dehumidifier on and off as needed, keeping the air in your crawl space healthy and dry.

Is a Crawl Space Dehumidifier Necessary?

If you want your home’s air quality to stay dry and healthy, a crawl space dehumidifier is necessary. Without one, high humidity can damage your home’s structure, harm indoor air quality, and lead to costly repairs.

Installing a dehumidifier helps prevent these issues and protects your home long-term. Keep in mind, a standard dehumidifier from a big box store isn’t powerful enough for a damp crawl space.

For the best results, work with JES Foundation Repair. You’ll receive a high-quality dehumidifier that can remove up to 100 pints of water per day and is self-draining.
