Finding Hope In The Wake Of A Fire

Can Mold Grow On The Concrete In Your Crawlspace Or Basement?

Many people think of mold as a problem that primarily infests wet fabric and wood, but it's a far more versatile life form than that. There are a surprising number of materials that can harbor the growth of health-impacting mold as long as enough moisture is present. Discover why concrete is one of the most common materials in a home to harbor mold and allow it to spread through the rest of the home.

Ready Source of Moisture

First, concrete in the crawlspace or basement is capable of providing all the moisture mold needs to grow through its capillary action. Tiny channels inside the concrete draw moisture out of the soil it touches outside of the home, bringing that water inside where it fuels mold development and other serious problems. Sealing the concrete is one way to stop the capillary action, but it won't work if the sealant is applied over an existing layer of mold growth, dust, or moisture. If you're building a new home, have the construction company apply a sealant to the outside of the concrete for the most effective moisture control.

Accumulation of Dust

Mold also needs a source of food to digest, and it grows and spreads on a surface. Basements and crawlspaces very quickly develop coatings of dust, and cleaning the dust off is very difficult with your usual cleaning supplies because of the rough and porous surface of the concrete. Again, painting or sealing the concrete is usually the best way to create a smooth and sealed surface you can wipe clean of dust. You may need to use a low-pressure washer to remove the dust, or at least a scrub brush, some bleach solution, and a way to mop up the water.

Difficulty of Treatment

The same porosity and roughness of the concrete surface also make it difficult to remove all of the mold and mildew spores, resulting in a problem that keeps coming back. If your home's mold problem started with the concrete in your basement or spread to it, you'll the help of the professionals to remove it and test to verify that it's gone.

Source of Structural Damage

Finally, allowing mold to grow on the concrete in your crawlspace or basement doesn't just ruin the interior air quality in your home. It can also weaken the concrete itself and potentially make your home unsafe and unstable. Take any mold you see on concrete seriously and treat it immediately instead of assuming it's just a normal occurrence.
