The 48-hour rule, the three water categories, and exactly when wet carpet can be saved — a guide for DFW storm season and plumbing failures.
Quick answer: two factors decide everything — how clean the water was, and how fast you act. Clean water (supply line, rain through a window) extracted within 24–48 hours: carpet is usually savable, though pad often is not. Gray water (washing machine, dishwasher): carpet savable with professional sanitizing, pad replaced. Sewage or outdoor floodwater: carpet and pad both go, no exceptions — that is a health rule, not a cleaning rule.
Stop the source, kill power to affected outlets if water is near them, and get furniture up on foil or blocks. Extract standing water fast — wet/dry shop vac for small areas; professional water extraction for anything room-sized, because consumer equipment cannot pull water from padding. Then air movement: every fan you own plus the HVAC running. The clock matters because mold can establish within 24–72 hours in Texas humidity, and it does not announce itself.
Carpet fiber is designed to release water; padding is a sponge that holds it against the slab or subfloor. Even when carpet dries beautifully on top, saturated pad underneath stays wet for days — the source of the "we dried it but it smells musty now" story. Standard practice for genuine soakings: lift the carpet, replace the pad, clean and reinstall the carpet. Pad is cheap; the mold remediation it prevents is not.

North Texas generates these calls in two seasons: spring storm flooding and the hard-freeze pipe bursts every few winters. If water sat more than 48 hours, or you smell must a week later, bring in professionals — moisture meters find what noses miss.
Mold can establish in 24-72 hours in warm, humid conditions. The 48-hour extraction window is the practical deadline for saving carpet.
Rarely worth it - pad holds water against the floor, dries very slowly, and costs little to replace. Standard practice is new pad under cleaned carpet.
Usually for sudden events (burst pipes, appliance failures), not gradual leaks or outside flooding (separate flood policy). Document everything and call early.
