Tips for Preventing Mold in Crawl Spaces

For many, a crawl space is out-of-sight, out-of-mind. But that doesn’t mean it isn’t affecting your quality of life. As much as 50% of all air in your household emanates from your crawl space. If the space under your house is moldy, then you could potentially be breathing in harmful spores every day. That’s why its important to take preventative measures.

  • Inspect for leaks: It’s no secret that mold loves a damp environment. The first step to take in addressing mold is to inspect your crawl space for leaks in the foundation, pipes or vents.
  • Adjust your gutters: Ensure that your gutters are clean and collecting rainwater properly. Clogged gutters can lead to overflow, dumping water around the foundation of your home.
  • Reroute rain water: Speaking of rain water, it’s important to ensure you have a system to divert unwanted water away from your foundation. If your gutters and downspouts aren’t enough, you may need to install French drains or a sump pump.  
  • Check your vents: venting a crawl space was thought to encourage air circulation and prevent mold. But sometimes they function in just the opposite manner by allowing heavy, humid air into the crawl space, which encourages mold growth. Seal vents to prevent excess moisture from entering.
  • Use a dehumidifier: A dehumidifier is an excellent defense against mold. It works hard to pull excess moisture from the air and condense it into water that can either be dumped or pumped away from your home.
  • Use a vapor barrier: Vapor barriers are large, high-quality sheets of plastic installed on the floor of your crawl space to create a waterproof barrier between the ground and your home. They are considered the first line of defense in condensation control.
  • Encapsulate Your Crawl Space: Crawl space encapsulation is the ultimate preventative measure against a moldy crawl space. An encapsulation addresses mold by removing any damaged materials like insulation, treating existing mold, and then sealing your entire crawl space with heavy-duty vapor barrier to create a self-contained environment.
