Crawl spaces can be naturally prone to excess moisture buildup. With everything from humidity to moisture intrusion, your crawl space can easily fall victim to major moisture damage and mold contamination. However, crawl space moisture and crawl space mold are not completely inevitable. There are a variety of moisture preventatives that Ohio homeowners can implement to control crawl space moisture and prevent crawl space mold growth. The right combination of the appropriate moisture control tactics can keep your crawl space clean, dry and problem free.

If your building structure is built on a crawl space with a dirt floor, a properly installed vapor barrier can be the solution to a number of common moisture related problems. Dirt or sand floors emit moisture or water vapors all year-round. These water vapors rise with normal air currents in you crawl space and eventually wind up clinging to your wood floor joists, sub-flooring and insulation. A crawl space vapor barrier is a layer of plastic installed over the dirt floor of a crawl space. A vapor barrier controls crawl space moisture levels by slowing or preventing the evaporation of ground moisture into the crawl space air.

Crawl Space Mold Prevention Cleveland Ohio

Crawl spaces are one of the most common areas for mold development due to the traditionally damp conditions. Without the proper precautions (like a properly installed vapor barrier), crawl spaces are especially vulnerable to moisture buildup that can feed a major mold contamination. Severe mold growth can lead to property damage, potential health issues and expensive repair costs. In order to protect your property and family from the side effects of mold, you should implement the proper preventative measures. The key element to mold prevention is moisture control. If your building structure is built on a dirt crawl space, you might notice elevated humidity and general dampness in your crawl space. This could be caused by the water vapors being released from the dirt floor. This dampness can feed a serious mold problem if homeowners are not careful. A vapor barrier can control the evaporation of water vapors from the dirt floor into the crawl space air and prevent crawl space mold growth.

If you uncover a potential mold problem in your crawl space due to unaddressed moisture buildup, you should contact a crawl space mold removal professional.
