What causes crawl space problems? Moisture causes crawl space problems. Three things destroy organic materials, particularly wood, of which your flooring system, the ceiling of your crawl space, is made of: water, heat, and ultra-violet radiation. Of these, water is really the only one we can control.

Why Remove Moisture From a Crawl Space?

Dirt crawl spaces, vented crawl spaces, or unconditioned crawl spaces of any type under a home are a very bad idea - and a crawl spaces in Eastern Iowa and Western Illinois suffer big temperature and relative humidity swings through the seasons. The earth has very high humidity in the soil. This humidity or water vapor easily moves into the crawlspace and upwards into the house environment.

Crawl Space Mold, Musty Odor, and Home Healthiness

Damp environments, like an unconditioned crawlspace , are unhealthy and destructive. Places where mold thrives and spreads. Places where insects and critters of all kinds love to live and die. Places that cause heating and cooling costs to rise, especially if you have a vented dirt crawl space. Rot and decay occur in damp environments as well, causing structural damage to the organic building materials of which a house is made.

To add to this, natural airflow in a house goes from bottom to top. This sucks moist air and everything in it up into the living areas of the home. Mold spores, humidity, odors, and insects create unhealthy environments for people. Many people are allergic to these things and experience a host of symptoms, many times not realizing that their crawl space is affecting their health. We've heard countless stories of how people felt poorly in their own home with an unconditioned crawl space, and better when they left.

Is Waterproofing a Crawl Space Enough?

The answer is "No." Crawl spaces do not have to be wet or flooded to be extremely unhealthy.

However, in the case where the crawlspace floods or standing water is present, this must be addressed first. MidAmerica Basement Systems has the right solutions for keeping water out of a crawlspace. From drainage to the best crawl space sump pump systems available in Eastern Iowa and Western Illinois, we can keep your crawlspace dry.

How to Solve a Crawl Space Moisture Problem

Once standing water is removed, the problem of moisture in the crawl space, typically from high levels of humidity, can be addressed. For houses with damp or wet crawl spaces, installing a vapor barrier is the first step, and in some cases the only step needed, to solve the problem. In most cases additional products and sealing is required. One such product, the SaniDry CSB crawl space dehumidifier, not only dries the crawl space, but lowers the relative humidity throughout the entire house.
