Why Ignoring Mold Spores in Your Crawl Space Is a Bad Idea
If you find mold spores or microbial growth in your crawl space, you should never ignore it. It's a sign you have a moisture problem and could be on the way to costly damage to both your home and your health if it's not handled quickly by a professional.
Mold Spores Are One of the First Signs You Have Moisture in Your Crawl Space
Your mold spores may look like:
- Tiny white, gray, green, or even black dots spread across wooden elements
- Powder-or-dust-like patches on the joists and beams
- Discolored wood that's also fuzzy or blotchy
- Stains that resemble dirt but don't wipe away easily
This is an early warning sign of moisture, meaning you can remove the mold spores, but if the moisture problem isn't addressed, the mold spores will return.
Moisture in a crawl space is a significant problem to have because it can lead to rotting, smelly odors, health problems like respiratory aggravation, and, when left for extended periods of time, can even contribute to structural damage.
What Will Happen If I Don't Treat The Mold Spores?
These tiny specs, powdery patches, or stains may look harmless, but they will continue to spread and grow into mold over time.
Black mold is a bad problem to have. It will eventually contribute to wood deterioration, weakening the structural elements that support your home. If black mold is present, it also means you likely have high humidity levels, water somewhere in the crawl space, or trapped moisture. Other problems may exist, like condensation, failing insulation, and rust.
You may notice higher energy bills from poor energy efficiency as your HVAC system works harder to maintain a comfortable temperature.
It can also negatively affect the air quality throughout the entire home, not just the crawl space. Mold can release musty odors and release nasty particles into the air that may significantly impact friends and family with allergies, asthma, or respiratory illness.
