How To Prevent Mold in Your Crawl Space


No one wants to spend a ton of time on their hands and knees in their home’s crawl space. After all, it’s dark and often damp—yet that’s exactly why you should give it some attention periodically. If left uninspected, crawl spaces can be a hotbed for mold and mildew that threaten your home’s structural integrity and lower your indoor air quality. We’ve put together a brief guide on how you can prevent mold from infiltrating your crawl space and what to do if it takes over.

5 DIY Tips for Mold Prevention

The good news is there are several steps you can take to prevent mold or stop its spread once it has appeared. The following five are the most effective:

  1. Stop leaks: Take a flashlight and search every corner of the crawl space for leaks and standing water. HVAC ducts and plumbing components are common sources of leakage.
  2. Seal cracks: Cracks in the foundation walls and crawl space ceiling are prime areas for moisture to build.
  3. Adjust gutters: Your gutters and downspouts can quickly cause mold growth, so be sure they direct water away from the foundation rather than toward it.
  4. Check insulation: If you see insulation sagging or missing in sections, you likely have a moisture problem you need to deal with.
  5. Check vents: Dryer vents are sometimes set up to discharge into the crawl space, creating excessive humidity that can be hard to control. If possible, make sure dryer vents discharge to the outside.

Professional Mold Prevention Techniques

Although going through the DIY checklist is important, there is only so much you can do to keep your crawl space clean and dry year-round. When you work with a professional service, you have several options for mold defense that you couldn’t replicate on your own. Alpha Foundations offers the following crawl space services to stop mold in its tracks.

  1. Dehumidifier: A dehumidifier with a powerful blower can dry large areas and filter out mold spores. We use dehumidifiers that automatically shut off when optimal humidity is reached.
  2. Encapsulation: A step up from a dehumidifier alone, encapsulation seals off your crawl space to stop water intrusion, stop seepage, and seal air leaks to keep the space dry.
  3. Insulation: Rigid foam insulation and sealing is an excellent way to repel mold and improve your indoor air quality.
