Common Mold Locations in Napa Homes
- Crawl spaces — ground moisture and limited ventilation create ideal mold conditions beneath Napa homes
- Attics — inadequate ventilation causes condensation that supports mold growth on roof sheathing
- Behind bathroom walls — tile grout is surface mold; mold on drywall behind tiles is a more serious concern
- Wall cavities after water damage — mold colonizes wet drywall paper within 24–72 hours
- HVAC systems — cooling coils and condensate pans that develop mold distribute spores throughout the building
- Basements and lower levels — foundation seepage and flooding create persistent moisture
