Do You Have Mold In Your Crawlspace?

6/20/2019 (Permalink)

Do you have problems with moisture in your crawlspace? Has a water leak caused mold, mildew or wood rot?

Crawl spaces are prone to mold growth due to the high levels of moisture and humidity in these areas. Some of the most common causes of increased levels of humidity in the crawl space include water leaks, damaged insulation, and inadequate ventilation. To get rid of a mold problem in the crawl space, you have to control the moisture and humidity levels. Review our tips for how to prevent mold issues;

  • 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.If you have a mold problem in your home or business, consider the following facts:
  • Call SERVPRO of Edmonds. Our trained and certified mold remediation technicians can diagnose your crawlspace moisture problem and get your crawlspace dried out in no time. Our technicians will remove any wet insulation in your crawlspace, treat the mold and mildew with an anti-microbial solution, dry the wet floor joists or subfloor, and remove and reset the vapor barrier so that you have no more problems of moisture damaging your home environment.
  • Significant mold growth can occur in 48-72 hours.
  • Mold may present a greater risk to children, the elderly, and anyone with respiratory problems.
  • A strong, musty odor may indicate hidden mold behind drywall or under carpeting.
  • What to Do:
  • Stay out of affected areas.
  • Turn off the HVAC system and fans.
  • Contact SERVPRO of Edmonds for mold remediation services.
  • Don’t touch or disturb the mold.
  • Don’t blow air across any surfaces with visible or suspected mold growth.
  • Don’t attempt to dry the area yourself.
  • Don’t spray bleach or other disinfectants on the mold.
