Mold in Crawl Spaces
Mold prefers dark areas with plenty of moisture to grow. This is why crawl spaces often provide ideal conditions for mold to thrive. Common areas where mold can be found are on the floor joists and walls of the crawl space.
Signs of Crawl Space Mold
Some of the signs below may indicate an issue with mold in a crawl space.
- A musty odor in the home
- Floorboards become warped or buckled
- Pipes have broken
- Wiring and cables have issues
Causes of Crawl Space Mold
Standing water: If there is standing water in the crawl space, this means there could be a drainage problem or a plumbing leak. This should be immediately fixed.
Crawl space vents: Recent research indicates that these can sometimes do more harm than good. Outside air brought in to the crawl space cools down, which can increase the humidity level.
High humidity: Humidity levels above 60% are enough to cause mold in a crawl space.
Limiting Moisture in Crawl Spaces
These steps can help to ensure your crawl has a limited amount of moisture.
- Check foundation walls to make sure there are no cracks.
- Make sure downspouts face away from the home.
- Dryer vents should terminate to the outside of the home and not into the crawl space.
- Look for leaks around HVAC ducts.
- Make sure insulation is not sagging or missing.
If you suspect you have mold in your crawl space, it’s important to contact a mold remediation company. This way, the mold can be safely removed and future problems can be prevented.
