Key takeaways
- Damp soil and humid air under the house are common sources
- Mold on wood and insulation adds to it
- Pests and debris can also be to blame
- Fix the moisture and the smell usually fades
Air moves from the crawl space up into the house, so smells travel with it.
Common sources
Damp soil, humid air, mold on wood, wet insulation and debris all add odor.
Pests
Nests and droppings can contribute too.
The fix
Trace the source, fix the moisture and clean the space. The smell fades once there is nothing left to feed it.
