Mold is not always the black splotch on a bathroom ceiling. In Illinois homes it often hides behind drywall, under flooring and in crawl spaces where it grows for months before anyone notices. Here are the signs to watch for.

1. A musty or earthy smell

If a room smells like wet leaves or an old basement, especially after rain, mold is likely growing somewhere nearby.

2. Dark or fuzzy spots

Black, green, grey or white spotting on walls, ceilings, grout or window frames. Black mold removal should be handled professionally.

3. Peeling paint or bubbling wallpaper

Moisture behind the surface pushes finishes off the wall and feeds mold.

4. Warped or soft floors

Buckled hardwood or spongy subfloor points to water damage below, and mold usually follows.

5. Allergy symptoms that improve when you leave

Sneezing, coughing, headaches or irritated eyes that fade at work or on vacation are a classic indoor mold sign.

6. A past leak or flood

Any water event that was not professionally dried within 48 hours is a mold risk.

7. Condensation on windows and pipes

Chronic condensation means humidity is high enough for mold to grow.

8. Stained ceilings

Brown rings on a ceiling mean water has been there, and the drywall above may be moldy.

9. A damp crawl space or basement

Efflorescence on foundation walls, standing water or a damp smell in the basement almost always comes with mold.
