Burst pipe water damage starts the moment a pipe splits. A single supply line can dump gallons per minute into walls, ceilings, and floors. This guide shows you how to stop the water fast. It covers repair costs and how pros dry hidden damage before mold starts.

Find your main shutoff valve before you need it. Closing it stops burst pipe water damage in its tracks. Every adult in the house should know where it sits and how it turns.
| Home Type | Look Here |
|---|---|
| House with a basement | Check the front wall near the floor, where the water line enters |
| House on a slab | Look in the garage, laundry room, or utility closet |
| House with a crawl space | Find the access door; the valve often sits just inside it |
| Condo or townhome | Check under the kitchen sink or near the water heater |
| No indoor valve found | Look in the ground box by the street, near the water meter |
Turn round valves clockwise to close them. Push lever-style valves a quarter turn so they sit across the pipe. Test your valve twice a year, because old valves freeze in the open position.
Water expands when it freezes. Ice blocks a section of pipe. Pressure builds between the ice and a closed faucet. The pipe splits at its weakest point, often far from the ice itself.
| Material | How It Fails | Watch For |
|---|---|---|
| Copper | Corrosion thins the wall over decades; pinhole leaks grow into splits | Green stains on the pipe, low water pressure |
| PEX | The pipe flexes, but crimp fittings can fail at the joint | Moisture around manifolds and connectors |
| CPVC | It turns brittle with age; cold snaps crack it | Discolored or chalky pipe, small drips at elbows |
| Galvanized steel | Rust narrows the inside until weak spots burst | Brown water, frequent clogs, low flow |
Freezing causes most bursts, but corrosion and high pressure cause the rest.
The break you see is rarely the whole story. Water sprays into wall cavities, soaks the insulation, and drips down to lower floors. Drywall wicks water upward past the visible stain. By the time paint bubbles, the cavity behind it may hold gallons.
We open wet walls with clean flood cuts. Air movers then dry the studs and sill plates. We check ceilings below the break for sagging and hidden saturation. Then we rebuild them with proper ceiling water damage repair.
The plumber fixes the pipe. The restoration crew fixes your home. Insurance treats those as two separate bills.
| Job | Typical Range |
|---|---|
| Plumber repairs an exposed pipe | $150 to $450 |
| Plumber repairs a pipe inside a wall | $500 and up |
| Water extraction | $500 to $1,500 |
| Structural drying, 3 to 5 days | $1,000 to $3,000 |
| Drywall removal and replacement | $500 to $2,500 per area |
| Flooring repair or replacement | $800 to $5,000 and up |
Insurance usually covers the water damage from a sudden burst. It rarely covers the pipe repair itself. Read our full water damage restoration cost guide before you call your adjuster, so you know which bill goes where.
Thaws reveal bursts. Ice splits the pipe during the freeze, but you notice water only after the thaw restores pressure.
If the burst sent water across multiple rooms, start with emergency water removal. Standing water damages floors and baseboards within hours.
Prevention costs less than repair. Wrap exposed pipes in foam sleeves. Open cabinet doors under sinks on exterior walls so warm air reaches the pipes. See our homepage seasonal calendar for month-by-month winter prep.
The IICRC sets the industry standard for water damage restoration. The EPA explains how fast mold grows on wet building materials. FEMA publishes winter storm checklists that help homeowners prevent pipe freezes.
The pipe repair itself runs $150 to $450 for an exposed pipe and $500 or more inside a wall. The water damage cleanup adds $1,500 to $5,000 in most homes. Our cost guide breaks down each line item.
Yes. The ice splits the pipe during the freeze, but you see water only after the thaw restores pressure. Check every fixture for new leaks as temperatures rise.
You need both. A plumber repairs the broken pipe. A restoration crew extracts the water, dries the structure, and rebuilds the damaged areas. Call (800) 555-0199 and we handle the drying and rebuild.
Most policies cover sudden, accidental bursts. They exclude slow leaks and frozen pipes in unheated, vacant homes. Photograph everything before cleanup starts.
Extraction takes hours. Structural drying takes three to five days with commercial dehumidifiers and air movers. We verify every wall with moisture meters before we rebuild.
Shut the main valve, then call (800) 555-0199. We dispatch 24/7.
