If you suspect mold under a carpet, start by checking for a musty smell or discoloration. Lift a corner carefully with gloves and a mask, as mold can stir up spores. Look for black, green, or white patches on the carpet backing or padding. Moisture from leaks or high humidity often causes this growth, so address the source before replacing anything.
