Shut off the main water, turn off power to the area if outlets or switches are near the wet wall, and take photos. Then get the wall opened and dried quickly. Water trapped behind drywall keeps spreading and can grow mold within a couple of days.
Signs it's inside the wall
- Wet, stained or bubbling paint or drywall
- Drywall that's soft or bulging
- The sound of running water when nothing is on
- Water on the floor along the bottom of a wall, or coming through the ceiling below
- Your water meter still moving with every faucet off
Right now
- Shut off the main water. See how to find it.
- Turn off power to the room at the breaker if outlets or switches are on or near the wet wall, and only if you can reach the panel without standing in water.
- Take photos and video of the wall, floor, ceiling below and anything damaged.
- Open faucets on the lowest level to drain the lines.
- Move belongings away and start pulling up wet rugs.
Why speed matters
Drywall and insulation hold water against the studs and subfloor. Fans in the room won't reach it. A water damage company uses moisture meters to find how far it spread, opens the wall where needed, and dries the cavity with air movers and dehumidifiers.
For your claim
A sudden burst inside a wall is usually covered. A slow leak that went on for months is often treated differently. Keep the broken section of pipe if a plumber cuts it out. Use the claim checklist so nothing slips.
Common questions
Can I just let the wall dry on its own?
Usually not. Water trapped behind drywall can stay wet for days, which is how mold starts. A moisture reading tells you for sure.
Who fixes the pipe and who fixes the wall?
A plumber repairs the pipe. A water damage company dries the structure, and a contractor rebuilds the wall afterward.
Does insurance pay to open the wall?
For a covered loss, policies usually pay to access the leak and repair the damage. The broken pipe itself often isn't covered.
