Many homes that don't have a basement do have a crawl space. This is especially true in the southeastern United States. Although you may not realize it, excessive moisture and humidity are wafting up from your crawl space into your home. This is where a high quality crawl space dehumidifier comes into play.

The moisture laden air entering your home from the crawl space can affect your health and damage your home. Mold, mildew, wood rot and termites are just a few of the problems you will encounter if the high humidity in your crawl space is left unchecked. Mold can cause health problems and allergic reactions. Wood rot and termites can cause serious and expensive structural damage. The one thing mold, wood rot and termites have in common is that they need a source of moisture to survive. By controlling the moisture, you can protect both your health and your investment.

Many homeowners make the mistake of trying to use appliance grade dehumidifiers in their crawl space. Home and basement dehumidifiers ARE NOT designed and built for harsh crawl space environments. Either they can't to the job required or they are over sized units for a tight crawl space. Appliance grade dehumidifiers can freeze up in outdoor climates or will run continuously because they are being overworked. This will add significantly to your electric bill.

It's important to choose a dehumidifier that was designed and built for a crawl space environment. These units are designed to fit in a crawl space and are very energy efficient. When used with a vapor barrier, a crawl space dehumidifier can dramatically reduce the relative humidity levels in your home. Don't trust some kid at Lowe's or Home Depot to sell you the correct dehumidifier for your crawl space. Seek out professionals who feature equipment that was meant to solve your crawl space humidity problems.
