Mold Prevention Tips

According to the National Association of Homebuilder’s (NAHB) Household Mold Resource Center, you can take numerous precautionary steps to prevent mold growth.

Review these mold prevention tips to stop mold in its tracks:

  • Vacuum and clean regularly to remove possible sources of mold growth.
  • Pay special attention to bathrooms and other areas of your home that are likely to generate a lot of moisture.
  • In portions of your home that are susceptible to moisture, use area rugs or washable floor surfaces rather than wall-to-wall carpeting. If you use area rugs, launder them periodically.
  • Do not store materials such as paper, books, clothes, or other possible sources of food for mold in humid parts of your home.
  • Repair water leaks in your roof, windows, or any other part of the home as soon as possible.
  • Clean refrigerator drip pans regularly according to the  manufacturer’s instructions. If your refrigerator and freezer doors do not seal properly, moisture can build up and mold can grow there. Remove any mold on the door gaskets and replace faulty gaskets.
  • If you live in a house, make sure that your gutters and  downspouts are clear of debris that may block the flow of water from your roof. Make sure the area under your downspouts is properly graded so that  rainwater from the roof flows away from your foundation. Splash blocks can help rainwater to flow in the proper direction. If necessary, extend your downspouts.
  • Make sure other areas around your foundation are graded so that rainwater does not flow toward the house.  Do not put gardens or plants too close to your foundation so that watering them could cause water to flow toward your house. If you water your lawn with a sprinkler,  make sure the water does not hit your house or the area next to the foundation.
  • In the kitchen and bathroom, open windows or use exhaust fans when engaging in activities that produce moisture. Exhaust fans should be vented to the outdoors and not to an attic or crawl space.
  • If you have a clothes dryer, make sure it is vented to the outdoors.
  • If you use a humidifier, make sure it does not produce an excessive amount of humidity.  During the summer, 60 percent relative humidity or lower probably will prevent condensation and mold growth in most parts of the country, but that is too moist for the middle of winter, when 40 percent relative humidity or lower will prevent condensation on windows.
  • If you live in a house with a basement, consider using a dehumidifier there. The cool basement floor and walls can be a source of moisture build-up.
  • If your home has an attic, make sure it is properly insulated and ventilated.
  • If you have a crawl space under your house, cover the soil in the crawl space with waterproof polyethylene plastic. If your crawl space is ventilated, close the vents in the summer and keep them open in the winter.
  • If you have water problems in your basement or crawl space, clean up affected areas as quickly as possible and take immediate steps to resolve the source of the problem.
