That musty smell is telling you something about what's under your house. Run this inspection before calling anyone — it takes 15 minutes and tells you whether you need a quick fix or a professional.
| Symptom in your home | Underlying crawl space cause |
| Cupped hardwood floors | Upward vapor drive — boards lift at the edges as they absorb moisture from below |
| Musty, earthy odors | Organic growth and mold colonies on damp wood joists and debris |
| Sagging fiberglass batts | Humidity saturation — insulation becomes heavy, pulls away, falls |
| Condensation on ducts | Crawl space air reaching its dew point on cool metal surfaces |
| Soft or bouncy spots | Wood moisture above 20% — structural decay and fungal rot |
| Allergy / asthma flares | The Stack Effect circulating mold spores and dust mites into the home |
The Stack Effect: warm air rises out of the top of the home, pulling humid, contaminated air up from the crawl space through floor gaps and utility penetrations.
