Burst & Frozen Pipe Emergency Repair
A burst pipe is a supply line that has split open — most often because water inside it froze, expanded, and cracked the pipe, or because age and corrosion thinned the wall until normal pressure split it. Emergency repair means shutting off the water, draining the line, and replacing the failed section before water damage spreads.
5 Urgent Warning Signs
- ⚠️ No water, or a sudden drop in pressure, at one or more fixtures during or after a freeze
- ⚠️ Water pooling, staining, or dripping from a ceiling, wall, or crawl space
- ⚠️ A pipe that looks swollen, frosted, or visibly split in an unheated area
- ⚠️ A hissing or spraying sound inside a wall or under the floor
- ⚠️ A water meter spinning with all fixtures off after a cold snap
4-Step Technical Protocol
Step 1: System isolation
shut off the main water supply immediately, open taps to drain the line, and shut off power to any affected electrical area.
Step 2: Damage mapping
trace the wet area to the failed section; check neighbouring runs, since one freeze event often damages more than one spot.
Step 3: Targeted replacement
cut out the split section and replace it with like-for-like or upgraded material, insulating the run if it sits in an unheated space.
Step 4: Flow verification
restore pressure slowly, check every joint for weeping, run all fixtures, and re-check the meter with everything off.
Frequently Asked Questions
What is the very first thing I should do if a pipe bursts?
Shut off the main water shut-off valve immediately (usually near the front hose bib, in the basement, or at the street meter). Then open the lowest faucet in the home to drain the line, and call for priority emergency dispatch.
Why do pipes burst when thawing rather than when freezing?
Ice expands and fractures the pipe while frozen, but the ice plug itself prevents water from escaping. When temperatures rise and the ice melts, pressurized municipal water rushes out of the split, revealing the burst.
Can copper or PEX pipes survive a freeze?
PEX has greater elastic flexibility than copper and can expand slightly during mild freezing, but repeated freeze-thaw cycles or extreme sub-zero temperatures will still split fittings and manifolds.
