What should I do about a burst pipe?

Shut off the main water valve first — everything else is second. Then kill power to the area if water is near outlets, open a faucet to drain pressure, and move what you can. Emergency repair of a burst pipe typically costs $500–$1,500 for the pipe itself; water damage is the expensive part, which is why the first 10 minutes matter most.

Likely causes

• Frozen pipe that thawed — The classic winter burst — the pipe splits while frozen and floods on thaw.
• Corroded or aging pipe — Old galvanized and copper lines fail at weak points, often at joints.
• Excess water pressure — Pressure spikes stress every weak point in the system.

What you can check yourself

• Main shutoff: usually near the street meter or where the line enters the house. Find yours before you ever need it.
• After shutoff, open the lowest faucet to drain the lines.
• Photograph everything for insurance before cleanup.

Typical cost
