Symptoms of Mold Exposure from your Crawlspace

The air from your crawlspace rises into the rest of your home. It is known as the "Stack Effect", where air being pulled out of the top of the house causes air from the bottom to be drawn upward, into your home, and out the top. If mold or other pollutants are present in your crawlspace, the air your breathing is unhealthy.

Mold in a crawlspace typically develops when there’s too much moisture and humidity levels rise above about 55–60%, creating perfect conditions for spores to grow and spread.

Early exposure symptoms include:

• Headaches
• Eye Irritation
• Sneezing
• Itching
• Skin Redness
• Skin Rash
• COPD
• Cancer
• Asthma
• Lesions
• Persistent cold or cough

To prevent mold from growing in your crawlspace, you must have a controlled and conditioned environment, meaning it is completely sealed off from outside conditions, as well as temperature and humidity regulation.

If you think you may have a problem with mildew or mold in your crawl space, but want to be sure, the best course of action is to contact a professional for a free inspection.
