What is a Crawl Space Dehumidifier? 

Crawl space dehumidifiers remove excess moisture from the area under your house, which often becomes damp from ground or atmospheric moisture. This dampness can encourage mold growth and damage your home’s structure.

In this process, a dehumidifier acts like a vacuum specifically for air moisture. It pulls humid air into the device where it passes over cold coils. This causes the moisture in the air to condense into water, which is then collected in a tank and drained away.

The dehumidifier needs to run regularly to keep the crawl space dry, and it often includes a hygrometer to measure air humidity. This tool allows the dehumidifier to automatically turn on and off as needed to maintain optimal dryness, ensuring the structure of your home remains sound and the indoor air quality stays healthy.

Signs You Need a Crawl Space Dehumidifier 

In your home, there are a number of signs that indicate problems with your crawl space. It’s important to identify these signs early, as ignoring them can lead to bigger issues and more expensive repairs later on.

Yes, a crawl space dehumidifier is important for keeping the area under your house dry and stable. Too much moisture can harm your home’s structure and make the air inside uncomfortable. By installing a dehumidifier, you stop these problems now and prevent new ones from starting.

Getting help from professionals like Foundation Recovery Systems is the wiser choice. Our team knows exactly how to handle these issues, and with us, you receive an industry-leading dehumidifier.
