Crawl Space Mold – Causes and Removal | Bay Crawlspace

Crawl Space Mold Causing Health Issues?

Crawl space mold and fungus grows as a result of moisture in the crawl space and can cause health issues in 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. If you’ve noticed people in your home experience sinus issues, headaches, or feeling achy, you might have crawl space mold.

The Main Causes of Crawl Space Moisture and Mold:

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. Science has shown that 95% of molds cannot thrive in a dry climate. For this reason, we recommend working to reduce the crawl space humidity to 65% or less. Without moisture, mold cannot continue to grow and release harmful irritants.

How to Reduce Crawl Space Moisture to Prevent Mold Growth:

Eliminate the moisture from standing water with a French drain and sump pumps OR sand in special circumstances. If the crawl space floods, your home is at risk for mold growth.

Eliminate the moisture from the damp earth with a vapor barrier or crawl space encapsulation. Moisture from the damp earth must be covered with vapor barrier to control moisture.

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. With our Dry Space Encapsulation, we 100% guarantee that your moisture levels will stay below 65% humidity, year around.

How to Kill Crawl Space Mold:

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.

Depending on the severity of the mold growth, we might recommend a heavier than normal treatment to ensure the safety of your healthy home.
