What to do right now
- Turn off the main, normally beside the meter where the service comes into the basement.
- Open a basement faucet so the pipes empty.
- Where water is reaching outlets or the breaker panel, keep clear and shut power off only if it is safe to reach.
- Move valuables, take photos and call us, then your insurer.
Why pipes burst
Freezing is the classic cause: water expands in a pipe inside an outside wall, a garage ceiling or an unheated crawlspace. The crack frequently opens some distance from the ice itself, in the section where pressure is trapped. Corroded copper develops pinholes that can open suddenly. Nails and screws from renovation can sit in a pipe for years before rusting through. Failed push-fit or crimp fittings also count.
The repair
- Locate the failure; with a frozen line there may be more than one split.
- Cut out damaged pipe back to sound material.
- Join new copper, PEX or CPVC to match the system, using soldered, crimped or approved push-fit joints.
- Restore pressure slowly and check every fitting.
- Recommend insulation, rerouting or heat where freezing was the cause.

After the repair
Wet drywall and insulation need to dry or be removed to prevent mould. Water damage restoration companies handle that; we focus on the plumbing and will tell you what we saw inside the wall.

Quick answers
Will insurance pay?
Many policies cover sudden bursts but not gradual leaks. Ask your insurer about your coverage.
My main valve will not close. What now?
A curb stop near the lot line can isolate the home, though the City normally operates it. Call us and the City.
