Key takeaways
- Mold needs moisture, a food source and time
- Wood and dust are plenty of food
- Fix moisture first, then clean
- Cleaning alone does not last
Mold spores are everywhere. They only grow where there is moisture, something to eat and enough time.
Why crawl spaces are a target
Wood, paper-faced insulation and dust provide food. Humid air, leaks and damp soil provide the moisture. Dark, still conditions give it time.
The right order
- Stop the moisture with drainage, a liner and humidity control
- Remove the mold safely and clean or treat the wood
- Monitor humidity so the problem does not return
Why spraying alone fails
If moisture stays, mold comes back. Cleaning without fixing the cause is a temporary answer.
