How to Prevent Crawl Space Mold

• Check for water leaks in the foundation walls and crawl space ceiling — make sure there are no cracks that allow water to leak inside the crawl space. While checking for cracks, be sure to also inspect the HVAC ducts and plumbing components for leaks.
• Ensure that the gutters and downspouts direct water away from your home’s foundation. Water that flows toward your house could enter your crawl space and basement.
• Make sure your crawl space is properly ventilated — for every 150 square feet of crawl space area, there should be 1 square foot of ventilation. However, consult a professional to determine if you should keep the crawl space vents closed and, if so, find other ways to control the humidity in the crawl space.
• Use plastic sheeting covers to insulate/encapsulate the crawl space floor and foundation walls. Vapor barriers like plastic sheeting covers trap the moisture that is evaporating from the soil and walls.
• If your crawl space is already insulated, inspect the insulation once or twice a year. Make sure the insulation is not missing or sagging, which indicates that there could be a water problem.
• Make sure dryer vents always discharge to the outside and not into the crawl space, attic or other area of the house. If they don’t, this can lead to a major increase in humidity.

Follow the above tips and the relative humidity in your crawl space should reach the desired level of 30 to 50 percent. Mold will easily grow if the humidity is above 70 percent.  For Mold Remediation and Water Damage repair, contact SERVPRO of Oldham/Shelby.
