Do this first
- Close the main water shutoff. On a well, it's the valve right after the pressure tank. You can also switch off the well pump breaker.
- Stay out of water near outlets and appliances. If you can reach the panel safely, cut power to the wet area.
- Open the faucets on the lowest floor to drain what's left in the pipes.
- Take photos of the break and the damage before cleanup, for insurance.
Why pipes burst
Most bursts come from freezing. Water expands as it turns to ice and builds pressure in the pipe. Pipes in exterior walls, crawlspaces, garages and attics are the usual suspects. Corrosion, high water pressure and shifting foundations cause the rest.
A frozen pipe that hasn't burst yet can be thawed slowly with a hair dryer or space heater kept at a safe distance. Never use an open flame.
What the repair costs
Burst pipe repairs typically cost $200 to $3,000, with an average around $500. Labor is most of the bill, so a pipe behind finished walls or under a slab costs more to reach than one in an open basement.
| Where the pipe burst | Typical repair |
|---|---|
| Kitchen | $150 – $500 |
| Inside a wall | $150 – $500 |
| Bathroom | $150 – $800 |
| Basement | $200 – $600 |
| Sprinkler line | $150 – $350 |
Then deal with the water
Wet drywall, insulation and flooring need to dry within a day or two to avoid mold. See water damage first steps for drying, insurance and restoration costs.
