Crawl Space Mold – Causes and Removal | Bay Crawlspace

Crawl space mold grows as a result of moisture in the crawl space and can affect the health of the home. A wet crawl space is caused by a combination of issues leading to mold in the crawl space which will contaminate the air and infiltrate inside the home. Up to 50% of the air in a home can come from the crawl space due to the “Stack Effect”.

Mold and mildew in the crawl space are known to cause respiratory health problems like coughing, wheezing, or lung disease. People with allergies or immunity weaknesses may have more severe reactions.

The main causes of moisture in crawl space are:

1. moisture from the damp earth

2. Moisture from standing water

3. Moisture from outside humidity.

In order to prevent mold growth, you must eliminate the sources of moisture.

You eliminate the moisture from the damp earth with a vapor barrier or crawl space encapsulation.

You eliminate the moisture from standing water with a French drain and sump pumps OR sand in special circumstances.

You eliminate the moisture from outside humidity with a crawl space encapsulation which includes a vapor barrier, sealed vents, wrapped piers, insulated walls, and a crawl space dehumidifier.

While addressing the sources of moisture, it’s important to treat the mold and fungus.

We recommend killing the mold and fungus with a product we use called Bora-Care with Mold-Care, a premium mold treatment product. Bora-Care with Mold-Care also helps create a protective barrier against mold, termites, and other wood-destroying pests.
