You might think you can just scrub that moldy carpet, but if it's been wet for over 48 hours or the padding is soaked, removal is the only safe bet. Mold can seep deep into the underlay and subfloor, making cleaning useless and risking your family's health. If you see black spots spreading, smell a musty odor, or the carpet was in a flood, it's better to rip it out. Don't forget to dry and disinfect the floor beneath before installing new carpet.
