Signs Your Pipe May Have Burst
Catching a burst or leaking pipe early can limit water damage and repair costs. Watch for these warning signs:
- Sudden drop in water pressure – If taps or showers go weak with no obvious cause, a pipe may have ruptured or sprung a leak.
- Water stains on ceilings or walls – Brown or yellow patches often indicate water leaking from a pipe above or inside the wall.
- Wet or sagging drywall – Soft spots, bubbling paint, or damp drywall suggest an active leak behind the surface.
- Sound of running water in walls – If you hear water when no taps or toilets are in use, a pipe may be leaking or burst.
- Unexplained puddles, damp basement floors, or a sudden spike in your water bill can also point to a burst or leaking pipe.
What To Do If A Pipe Bursts
Acting quickly can reduce water damage and keep your family safe. Follow these steps while you wait for a plumber:
- Shut off the main water valve – Turn off the main supply to stop more water from entering the system. The valve is usually near the water meter or where the main line enters the building.
- Turn off electricity near flooding – If water is near outlets, appliances, or the electrical panel, turn off power to that area to avoid shock or fire risk.
- Drain faucets – After shutting the main, open cold taps on the lowest level to drain remaining water from the pipes and relieve pressure.
- Call an emergency plumbing service – Contact a 24/7 plumber for burst pipe repair. Our dispatch connects you with licensed plumbers who can assess the damage, make the repair, and help with next steps for drying and restoration.
If the burst is linked to a sewer backup or basement flooding, our team can also connect you with plumbers who handle drain and sewer emergencies.
Why Burst Pipes Happen in London Ontario
London and the surrounding region see cold winters and frequent freeze-thaw cycles, which put extra stress on plumbing. Common causes of burst pipes in the area include:
- Frozen pipes – When water inside a pipe freezes, it expands and can crack or burst the pipe. Pipes in unheated crawl spaces, basements, or exterior walls are especially at risk.
- Cold winters – Extended periods of sub-zero temperatures increase the chance of freezing, especially if heating fails or a pipe is exposed to a draft.
- Aging infrastructure – Older homes in London, St Thomas, and nearby towns often have galvanized or older pipes that are more likely to corrode, weaken, and eventually burst under pressure.
- Pressure spikes – Sudden changes in water pressure from the municipal supply or from a malfunctioning pressure regulator can stress weak spots in the system.
Regular maintenance and insulating exposed pipes can help, but when a burst happens, you need fast emergency plumber service. Our dispatch is available 24/7 for London Ontario and nearby communities.
Burst Pipe Repair: What to Expect
When you call for burst pipe repair, a plumber will typically locate the burst, shut off water to that section if needed, and replace or repair the damaged pipe. For severe freezing or multiple failures, they may recommend repiping part of the system. They can also advise on drying out affected areas to prevent mould and further damage.
If you're also dealing with a clogged drain or slow drains after a burst, mention it when you request service—many of our plumbers handle both emergency repairs and drain cleaning in London.
