Frozen or Burst Pipe
If a tap gives little or no water in freezing weather, a pipe has likely frozen; thaw it gently before it bursts. A plumber typically charges around $100 to thaw pipes and $150–$500 for an accessible frozen pipe repair. A burst pipe repair usually costs $400–$2,000, plus any water damage.

If it burst: shut the main valve
Turn off the main water valve immediately, and open a tap to drain pressure.
Signs it's this problem
- Little or no water from a tap in freezing weather
- Frost on an exposed pipe
- Bulging or split pipe, or water spraying when it thaws
- Wet drywall or ceilings after a cold snap
Why it happens
Water expands as it freezes, building pressure between the ice blockage and the closed tap until the pipe splits. Pipes in exterior walls, crawl spaces, attics and garages are most at risk.

Common questions
Will frozen pipes thaw on their own?
Eventually, but a frozen pipe can burst while you wait. Thawing it gently with the tap open lowers the pressure and the risk.
Does insurance cover burst pipes?
Sudden bursts are often covered, but damage can be denied if the home wasn't heated or reasonable precautions weren't taken. Check your policy.
