Why Mold in Your Crawl Space Is a Big Deal – And How Americrawl Can Help
When most people think about home maintenance, mold might not be the first thing that comes to mind. Yet mold growth, especially in crawl spaces, can cause serious health issues and devastating structural damage to your home. Whether you are in Indianapolis, Bloomington, Lafayette or Carmel, if you have a dirt crawl space, it’s critical to understand just how much of a risk you're facing — and why professional help from Americrawl is essential to protect your home and family.
Why Does Mold Grow in Crawl Spaces?
Mold thrives under three specific conditions:
- Humidity: Mold needs a relative humidity above 50% to grow.
- Organic Materials: Wood floor joists, sill plates, beams, and plywood provide a perfect food source.
- Temperature: Mold can grow at temperatures as low as 28 degrees Fahrenheit.
A dirt crawl space is practically an invitation for mold. The exposed earth continuously releases an invisible stream of water vapor into your home. Meanwhile, the wood structures under your house easily absorb this moisture, setting the stage for mold and rot to take hold. Once wood becomes damp, it doesn’t just support mold—it also begins to smell, weaken, and rot.
Structural Damage Is Very Expensive
One of the most alarming facts about crawl space mold is the structural damage it can cause. As the wood under your home absorbs moisture and deteriorates, vital components like sill plates, floor joists, and girders can rot away. Repairing or replacing these structural elements is incredibly expensive—and unfortunately, it’s a booming industry. Homes as new as 10 years old are now seeing these problems, not just historic homes.
Left unchecked, crawl space mold can jeopardize the safety and stability of your entire home.
Mold and Real Estate Problems
Mold issues don't just impact the strength of your home—they can also tank its value. In today’s real estate market, a home with mold problems is very difficult to sell. Buyers are wary of any property with a history of mold, knowing the health risks and the high costs associated with mold remediation and repairs. If you’re thinking about selling your home in the future, addressing mold now is a smart investment.
Health Risks You Can't Ignore
Mold isn't just an eyesore—it’s a serious health hazard. People with asthma, allergies, or weakened immune systems are especially sensitive to mold spores. But even healthy individuals can suffer from respiratory issues when exposed to mold for extended periods.
What's even more concerning is that the air in your crawl space doesn’t stay put. Studies show that up to 50% of the air you breathe on the first floor of your home comes directly from your crawl space. That means millions of airborne mold spores could be circulating through your home every day without you even realizing it.
Additionally, crawl spaces provide ideal conditions for dust mites, which are the number one cause of indoor allergies. Dust mites thrive in humid environments but cannot survive when the humidity drops below 50%. Damp crawl spaces also attract a wide range of insects and critters—both living and dead—that can contribute to poor indoor air quality.
Americrawl Has Solutions
At Americrawl, we specialize in solving mold and moisture problems at their source. Serving Central Indiana, including Marion, Muncie, Anderson, Terre Haute and Greenfield, our team knows exactly how to handle the unique challenges that dirt crawl spaces and basements present.
Our solutions include:
- Crawl Space Encapsulation: Sealing your crawl space with a high-quality vapor barrier to stop moisture from entering. Americrawl uses the CleanSpace crawl space encapsulation system. This is a tough, 20mil thick, reinforced liner that can hold back the moisture, yet tough enough to make your crawl space area a usable space for storage.
- Dehumidification Systems: Keeping humidity levels under 50% to make your home inhospitable to mold and dust mites. Once you have removed the water seepage (water you can see) then it's time to dry up the air as well. Americrawl uses the Sedona Dehumidifier. This is a commercial grade unit, not available in your local big box stores and is sure to not only keep the air dry, but clean the air with it's dual filter system.
- Structural Repairs: Replacing or reinforcing damaged floor joists, beams, and sill plates to restore your home’s integrity. Americrawl is known for repairing floor systems, as many home inspectors refer to us as the "Cadillac" of structural wood repair. Whether it's a few feet of sill plate or a complete floor restructure, Americrawl is who to call.
- Waterproofing Solutions: Keeping basements and crawl spaces dry for good, protecting against future mold growth. Crawl space & basement drainage, often called a "French Drain" plays an important part in keeping your crawl space dry. If you are experiencing water seepage in the crawl space or basement, a drainage system is a must have. Our drainage systems route to a sump pump which then discharges that water to the exterior of the home.
We don't just patch the symptoms—we fix the problem at its root.
