House Crawl Space Fungus

The dark, damp environment of a home's crawl space can often make for prolific fungus growth. Be sure to check frequently and take steps to reduce the fungus growth so that it does not spread to the rest of the house.


Fungus can grow in the crawl space under a house because the area is dark, has poor air circulation and is damp. These factors combine to create an ideal environment for mildew to grow and spread.


High levels of humidity in a crawl space that lead to fungus growth under the house can encourage increased levels inside your home. This puts your living space at an increased risk of mildew growth.


You can prevent fungus growth in your crawl space by providing better air circulation through the area. If the soil is wet in the crawl space, dry it with a fan and then cover it with a layer of plastic. This will provide a moisture barrier between the soil and your home.
