Basements are one of the most common places where mold grows because they often have

1. High humidity (poor ventilation, especially in summer).
2. Moisture sources (leaks, condensation on pipes, seepage through walls or floors).
3. Organic material (wood, drywall, cardboard, stored furniture) that mold can feed on.

Signs of mold you should check right away

1. Musty or earthy smell.
2. Visible black, green, or white spots on walls, floors, or stored items.
3. Peeling paint, bubbling walls, or discoloration.
4. Increased allergy-like symptoms when spending time downstairs (sneezing, coughing, itchy eyes).

If you find mold, small areas can often be cleaned with proper safety gear and cleaning solutions. But if the mold covers a large area (over 10 square feet), it’s usually best to call a professional.
