Mold can hide in places you'd least expect, and it can cause health and structural problems before you notice. Here are five signs your home may need an inspection.

1. Persistent musty odors

If a damp smell remains after cleaning and airing out, mold may be growing behind walls or under floors.

2. Visible mold growth

Discolored patches on walls, ceilings, or floors — black, green, brown, or white — can be a sign of a larger problem behind the surface.

3. Recent water damage

Mold can start growing within 24–48 hours after a leak or flood. Drywall, insulation, and carpet hold moisture for a long time.

4. Health symptoms that worsen indoors

Sneezing, congestion, headaches, or asthma that get worse at home are common signs of indoor mold exposure.

5. High humidity or condensation

Foggy windows, damp walls, and humidity above 60% create the right conditions for mold.
