Why the first 24–48 hours matter
The EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth. After that, porous materials like drywall, carpet pad and insulation become much harder to save.
Stop the water source first, then start drying.

What to do right away
Turn off water or power if safe, remove standing water, move wet furniture and rugs, and run fans and dehumidifiers. Open cabinets and closets to let air move.
Take photos and notes of the damage and your drying steps — they help with insurance claims.
Mold can start growing within 24–48 hours of a leak. Speed is everything.
