Drying & repair
Wet carpet: save it or replace it?
Updated
Short answer
Carpet soaked with clean water can usually be saved if extraction and drying start within about 24 to 48 hours; the pad is usually replaced. Carpet soaked by sewage, outside floodwater, or water that sat for days should be replaced.

Usually savable
- Clean-water leak (supply line, water heater)
- Extraction started quickly
- No delamination (backing separating)
- No lingering odor after drying
Usually replaced
- Sewage or toilet backflow
- Outside floodwater
- Wet for several days
- Delaminated, shrunk or stained beyond cleaning
Why the pad is different
Foam pad holds a lot of water, dries slowly and is inexpensive, so it's usually replaced even when the carpet is saved. Removing it also lets the slab dry.
