wood, insulation, and paper-backed surfaces • Long-term moisture is usually required for growthRegardless of species, black mold indoors is a problem that requires action.⸻Why Black Mold Is Common in Merritt Island HomesMerritt Island’s environment creates ongoing moisture exposure.Contributing factors include: • High year-round humidity • Coastal air moisture • Heavy rain and storm activity • Roof leaks and flashing failures • Plumbing leaks behind walls • AC condensation and clogged drain lines • Crawl spaces and slab edges retaining moisture • Power outages after storms increasing humidityBlack mold typically develops where moisture remains for extended periods.⸻How Black Mold DevelopsBlack mold usually forms after unresolved water or humidity problems.Common triggers include: • Slow plumbing leaks • Roof leaks soaking drywall or insulation • Flooding or standing water • High indoor humidity above 60% • Wet building materials that never fully dry • Poor ventilation in bathrooms and closetsMold can begin growing within 24–48 hours, but black mold often indicates longer-term moisture exposure.⸻Common Places Black Mold Is FoundBlack mold often grows in hidden or low-airflow areas.Typical locations include: • Behind drywall and baseboards • Bathrooms and shower walls • Under sinks and inside cabinets • Closets on exterior walls • Inside HVAC systems and ductwork • Attics with roof or ventilation issues • Crawl spaces • Under flooring after water damageVisible black mold usually means additional hidden growth exists.⸻Signs of Black Mold in the
