When burst pipe repair can't wait
A pipe does not need to explode dramatically to count. A pinhole spraying inside a wall, a split along a copper line after a cold night, or a crimp fitting that has let go on a PEX run all leak at full house pressure until someone closes a valve. Every minute adds water to insulation, drywall and flooring.
Close the main shut-off, open a tap on the bottom floor to drain the line, and call. If water is next to outlets or the electrical panel, keep clear of it.
Our step-by-step visit
- Find the break. Sometimes it is obvious. Behind a finished wall we follow the water marks and listen for the hiss before opening anything.
- Cut back to sound pipe. We remove the damaged section and check the pipe either side for thin walls or more splits.
- Repair with the right material. Copper is usually joined with copper; PEX with proper fittings; old galvanized often gets a transition to modern pipe.
- Pressure test. We restore water slowly and watch the repair and the joints nearby.
- Look for the cause. Freezing, corrosion, high pressure and physical damage each need a different follow-up.
After a freeze-burst, check every tap on the same wall. Ice often damages more than one spot.
Common causes in Durham homes
Frost is the leading culprit here. Lines along exterior walls, over garages and in crawlspaces are most exposed during a hard January cold snap. Corrosion is next: older homes in central Oshawa still have galvanized sections that rust from the inside until they give way. Water pressure that runs too high, or a failed pressure-reducing valve, stresses every joint in the house. Renovation nails and screws driven into a hidden pipe account for the rest.
Keeping it from coming back
Insulate and reroute lines that sit in cold spots, and fit a pressure gauge on an outside tap to check your pressure once a year. If corrosion caused the break, the pipe around it is likely tired too, and a partial or full replacement is worth discussing. Our winter plan against frozen pipes covers the cold-weather side. Water damage below grade can also expose weak drainage, so ask about sump pump repair or sewer line repair if the basement took water.
