Pipe Repair & Replacement in Toronto & the GTA
Toronto pipe repair means fixing the specific failure in front of you—leaks, pinhole holes, failed joints, rusted galvanized steel, or a damaged section of pipe—and deciding whether that pipe should be repaired or replaced based on its material and condition. Toronto's housing stock spans a century, and so does its plumbing. Pre-war houses may still carry galvanized steel that has rusted almost closed. Homes from the 1950s to the 1990s run on copper that develops pinhole leaks with age. Some late-century homes have polybutylene, a grey plastic pipe that fails at its fittings. Each fails in its own way, and a licensed plumber who has seen them all knows which repair is worth making and which pipe is telling you it is time.
For homeowners and property managers in Toronto and the GTA, acting quickly matters because aging or damaged pipes can lead to active leaks, water damage, mold, noise in the lines, and loss of a safe, reliable water supply. Below, you'll find what commonly fails, what to do in an emergency, how to get ready before the plumber arrives, when lead service lines or rusted systems point to replacement, what affects cost, and the licensing and repair questions people ask most often.
Call us and our assistant confirms what has failed and your postal code, then connects you live to a plumber who is available now. A planned repipe can go through the online request and reach the same plumber during calling hours.
When it can’t wait: burst pipes and emergencies
- Water is running from a pipe and the main valve, including the main water valve as the emergency shutoff point, is closed or cannot be found.
- The leak is near the electrical panel, an outlet or an appliance.
- A pipe has burst behind a wall or above a ceiling, the drywall is bulging, and water damage can spread fast.
- Frozen pipes can split, and once thawing starts the risk of burst pipes rises fast. Shut the main before it thaws further.

Common leaking pipes and pipe repair problems
Pinhole leaks in copper
A tiny spray from a pipe that looked fine yesterday. Pinhole leaks often start as tiny cracks or a small hole in the copper. Caused by corrosion from the inside, often in one section of a house at a time. Epoxy putty may be used as a temporary fix to seal the leak and create a watertight seal until permanent repair. One pinhole is repaired; a third in the same run usually means that run is replaced.
Galvanized steel that has rusted
Found in houses built before about 1960. It rusts from the inside, and rust plus sediment build up inside the pipe like debris, reducing flow and causing low water pressure; this can also lead to slow drainage or complete blockages, and homeowners may notice discoloured water. Repairs are temporary; replacement with copper or PEX is the fix.
Failed joint or fitting
A soldered joint that was marginal, a compression fitting that loosened, loose fittings, or a plastic fitting on polybutylene that has cracked. Usually a contained repair, once the water is off. For a leaky pipe, a temporary mechanical fix may use a gasket held in place with a hose clamp until proper repair. For example, a repair clamp creates a strong seal over leaks until proper repair is completed.
Lead service line and water supply concerns
Some older Toronto homes still have a lead pipe bringing water in from the street. Homeowners are responsible for repairs on private property, while the City of Toronto handles repairs on city property and offers a program for the private side. licensed plumbers can help determine where the issue lies and who is responsible. A plumber can tell you what your service line is made of.
Water hammer, banging, and frozen pipes
Loose pipes knocking when a valve closes, often heard as banging pipes, are caused by sudden changes in water flow. Sudden pressure shifts or low pressure can also point to pipe trouble. Air chambers or arrestors only work when properly installed within the plumbing system. Not a leak yet, but the movement wears joints. Securing the pipe, or adding an arrestor, is a small job and one of the common solutions that help cure the problem before movement leads to leaks. In winter, freezing temperatures can cause frozen pipes to crack or burst when ice expands inside them.
Before the plumber arrives
- Close the main shutoff valve if water is running; some homeowners may know it as the Main Water Valve. Open a tap on a lower floor to drain pressure from the system. Opening faucets on upper floors can also help drain pressure and slow water flow.
- Switch off power at the breaker to any room where water is near outlets, fixtures or appliances.
- Move belongings, put down towels, and take photos for your insurer before cleaning up.
- Watch for signs such as staining, soft drywall, or mold on any surface affected by the leak.
- If the leaking pipe is in a finished wall or ceiling, note where the water appears and where it is worst; the pipe run is usually nearby.
- Clear access to the area, and to the main valve and meter, so the plumber can see the pipe material and route.
What affects the cost
We do not quote prices; the plumber you are connected to does, before the work starts. These are the things that move the number.
Spot repair or section replacement
A single joint, pinhole, or broken pipe is quick. In most cases, a run with several failures, or galvanized pipe, is replaced as a length because repeated spot fixes are more work over time and do not stop the pattern.
Access
Exposed basement pipe is easy. Pipe inside finished walls, ceilings or under a slab means opening and later repairing the finish. Access through a crawl space can also add labour and inspection time, and hidden leaks left too long may damage finishes and lead to mold.
Material
Copper and PEX have different material costs and installation times. The plumber will say which suits the job and why, since copper repairs may require heat for soldering while PEX uses different installation methods. For a short-term leak hold, silicone tape may help contain water until full replacement is done. Temporary products may also help break the flow of water or contain a leak until permanent repair is done. Some emergency supplies can be picked up at a hardware store, but the permanent material choice still depends on the pipe.
Scope
Replacing one bad run and replacing every pipe in the house are very different projects. A whole-house repipe is planned work, quoted in writing, and not something to decide in an emergency.
Licensing and safety
Repairing or replacing water supply pipe is plumbing, a compulsory trade in Ontario requiring a Skilled Trades Ontario certificate of qualification (306A). Every plumber in our network agrees in writing to be fully licensed and insured as the province requires; ask for the number.
Replacing the water service line or making changes to the drain system in Toronto normally requires a plumbing permit and inspection. A licensed plumber knows when one is needed and will tell you whether they are pulling it. A professional plumber will also know when permit, inspection, and code requirements apply.
Questions about pipe repair
How do I know what my pipes are made of?
Look at an exposed pipe in the basement. Copper is dull orange or green-tinged; galvanized steel is grey and threaded at the joints, and a magnet sticks to it; PEX is flexible plastic, usually red, blue or white; polybutylene is grey plastic stamped PB. The service line at the meter may be a different material again.
Is one pinhole leak a sign the whole system is failing?
One is a repair. Several in the same run, over a year or two, mean that section of pipe has reached the end of its life and is better replaced than patched. The plumber will look at the pipe around the leak and tell you honestly which situation you are in.
Should I replace old galvanized pipe even if it is not leaking?
If your water pressure has dropped and the water runs brown after sitting, the pipe is rusting closed and will leak eventually. Replacing it is planned work, not an emergency, and can be done in stages. Use the online request and discuss timing with the plumber.
Do I need a permit for pipe work?
Repairing a section of existing pipe usually does not. Replacing the service line, altering drains, or a whole-house repipe usually does, and Toronto inspects the work. A licensed plumber knows the rules and will tell you whether a permit is part of the job.
Do you repair pipes yourselves?
No. 2plumbers.ca is a live call-connection service run by PatchLead. We confirm what has failed and where you are, then connect you on the same call to an independent plumber from our network who does the repair and quotes you directly. You pay nothing to use the service.
