You notice that musty smell in the basement, and when you peel back a corner of the carpet, the padding underneath is dark and damp—mold has taken hold. That spongy layer, often made from synthetic foam or rubber, traps moisture like a sponge, creating the perfect environment for mold to spread. Once it sets in, the padding is essentially ruined, and the spores can trigger allergies or breathing issues, forcing you to rip out the whole carpet to get rid of the problem.
