What Is Crawl Space Mold? 

Mold is a fungus that thrives in moist, dark, isolated environments. When it appears in a crawl space, it’s usually due to elevated humidity levels, water presence, and organic material such as wooden supports. 

Mold can take various forms, but it commonly appears as black, brown, white, or greenish spots and patches. 

It spreads through airborne spores, which can travel throughout your home due to the stack effect (the natural airflow in a building from bottom to top). This poses significant health risks, especially for those with mold sensitivities, asthma, or allergies.  

Addressing mold in your crawl space is crucial, as it affects not just the space itself, but the overall indoor air quality and structural integrity of your home. 

What Causes Crawl Space Mold? 

Mold needs three things to grow and thrive: 

  • Food source (organic material like wooden supports) 
  • Water/moisture 
  • Humid air 

Several other factors contribute to mold growth in crawl spaces: 

Addressing these issues as soon as you notice them is crucial to implementing effective repairs and preventing additional problems. 

Can You Fix Crawl Space Mold? 

Yes, mold in a crawl space can be fixed, but it requires a comprehensive approach to address the mold and its underlying causes. 

Trying do-it-yourself mold removal with bleach is not enough to entirely eliminate mold or stop it from returning. Your crawl space could contain health and safety hazards, so we do not recommend venturing into this area under your house. 

Active mold growth requires removal from a mold remediation specialist. Then, it’s crucial to tackle the moisture issues to prevent future growth.  

Ohio Basement Authority offers a whole-home solution, focusing on creating a dry and healthy crawl space environment. Our solutions eliminate the conditions that allow mold to thrive, ensuring long-lasting results and a safer home. 

How to Fix Crawl Space Mold 

As we’ve just mentioned, it’s important to have a professional remove the existing mold before addressing the moisture issues. 

After mold removal is complete, Ohio Basement Authority follows this approach:

DIY mold removal techniques like scrubbing with bleach are tempting, but this will not remove the mold completely or address its root cause.

Mold is frequently mistaken for wood rot. While both can impact structural integrity, wood rot is the primary attacker of crawl space joists and beams, leading to sagging floors. Wood rot is generally not toxic, but different types of mold can worsen health problems like asthma and allergies.
