Organic materials made out of natural components are attractive to mold and dust mite damage. Items like dust, fiberglass, and wood - mold thrives on.
Once mold has grown large enough to be recognized visibly, a much more serious moisture problems exists somewhere.
Mold is present long before it "grows" big enough to be seen by the naked eye. The invisible parts of the mold fungi are carried through the air like tiny dandelion seeds, landing on the surface of many potential food sources.
It breathes air, it consumes food, it requires water to survive, and fortunately when you take one of these components away, it dies.
Mold likes temperatures between 32 and 100 degrees F, and is typically found in places that are damp or humid for extended stretches of time.
Wet load-bearing girders and floors joists are under attack by mold.
Even minor growth in the crawl space can lead to musty odors and cause respiratory problems for people in the home.
It's important to remember that it's the moisture on the surface of the organic material, not the level in the air, that triggers mold growth.
In this photo, you can see the mold remediation has begun. The mold removal team is drawing air out of the crawl space and filtering it, while scrubbing down the subfloor.
Each joist will be individually scrubbed and washed down with powerful disinfecting agents to kill the existing mold and minimize the risk of mold spore becoming airborne.
In this picture, you can see that the mold remediation equipment has been removed and the Healthy Spaces crawl space team has installed a liner to stop water vapor from rising into the house.

Danielle of Leitchfield, KY, was troubled by her crawl space. Water had leaked in through the block foundation and created a musty environment. Mold and wood rot threated the integrity of her home. Our Design Specialist, Abe Ford, inspected her crawl space to design a permanent solution to keep the space dry and her home safe.
The key to controlling mold in your crawl space is to eliminate the humidity that keeps it thriving. We started off by sealing off all vents. Next, we treated the entire area with chemicals to kill any remaining mold and prevent regrowth. Lastly, we installed a vapor barrier that covers the dirt floor and will control moisture.
