Mold can affect both your property and the comfort of everyone living there. Here are the key signs that you may need a professional mold inspection.

1. Persistent musty odors

A musty or earthy smell that lingers after cleaning often points to mold inside walls, under carpets, or in closets on exterior walls.

2. Visible spots

Small black, green, or white spots in bathrooms, kitchens, or around windows can signal a larger problem behind the surface.

3. Recent leaks or water damage

In NYC buildings, leaks often come from the unit above, a riser, or a radiator. Ceilings, under sinks, and around windows are the first places to check.

4. Increased allergies or asthma

If symptoms improve when you leave home and return when you come back, indoor mold may be the cause.

5. Peeling paint or warped surfaces

Bubbling paint, cracked plaster, and warped floors show that moisture is trapped where mold can grow.
