When you peel back a corner of the carpet and see dark patches or a musty smell, that's often hidden mold thriving in the damp padding underneath. It can develop from spills, high humidity, or a slow leak that went unnoticed. Look for discoloration, a powdery or slimy texture, and that unmistakable earthy odor. If you spot it, the area usually needs prompt removal to prevent it from spreading deeper into the subfloor or affecting air quality.
