Warm, humid summer months are the perfect breeding ground for crawl space moisture issues — especially in the Southeast. In areas like Charlotte, Greensboro, and Columbia, rising temps and heavy rain can trap moisture beneath your home, causing damage you may not notice until it’s too late.
Here are the warning signs to watch for this summer.
1. Musty or Damp Smells
If you notice a lingering musty odor inside your home — particularly near floors, vents, or closets — it could be coming from a damp crawl space.
✅ Tip: Check for smells after a heavy rain or humid week. Odor buildup often happens faster in hot weather.
2. Increased Allergy or Respiratory Issues
Mold spores and allergens thrive in moist environments and can easily travel from your crawl space into your living space.
✅ Tip: If your family experiences more allergy flare-ups during summer, your crawl space might be the hidden cause.
3. High Indoor Humidity
A spike in your home’s humidity — even with the AC running — can indicate crawl space moisture intrusion.
✅ Tip: Use a hygrometer indoors. Levels over 60% may point to crawl space problems.
4. Condensation or Wet Insulation
Take a look inside the crawl space. Moisture buildup can cause condensation on wood framing or ductwork, and insulation may feel soggy or look droopy.
✅ Tip: Always wear a mask and gloves when inspecting crawl spaces in case of mold exposure.
5. Sagging Floors or Wood Rot
As moisture affects the structure below, you may feel uneven, bouncy floors or see signs of rot in beams or joists.
✅ Tip: These are signs the issue has progressed — it’s time to call a professional.
