Signs Your Crawl Space Needs Encapsulation
Musty Floors, Damp Air
Signs your crawl space needs encapsulation include musty smells on the first floor, cupping or soft wood floors, sweating ducts, damp insulation hanging down, visible mold on joists and indoor humidity that won't stay below 60 percent.
| Sign | What's Happening |
|---|---|
| Musty smell on the first floor | Damp crawl space air rising into the home |
| Cupping or soft wood floors | Moisture in the subfloor |
| Sweating ducts | Humid air meeting cold duct surfaces |
| Wet or fallen insulation | Condensation and moisture |
| Mold on joists | High humidity under the house |
| High indoor humidity | Crawl space air feeding the home |
Why Do Vented Crawl Spaces Stay Damp Here?
Vented crawl spaces stay damp in the Lowcountry because summer air is hot and humid. When it flows through the vents into the cooler crawl space, the moisture condenses on joists, ducts and insulation.
- Vents let humid air in all summer.
- Tidal and high water tables keep the ground damp.
- Ductwork under the house sweats.
