Pipe Repair & Repiping in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
Repeated pinhole leaks on copper, multiple PEX fitting failures, brittle polybutylene, or aged galvanized water supply all point to the same conclusion: the supply line has reached the end of its useful life. Tornado Plumbing & Drains repairs sections and full-home supply piping across Toronto and the GTA — replacing the run with copper or PEX, reusing the existing route where possible, and restoring access cleanly. Whether it ends up being plumbing pipe repair on one leaking section or a full repipe, we quote both after the trace so you can pick the scope that makes sense for your house.

These real project photos show the kind of work this service involves, so you can see examples before you book.
Basement floor opened to replace the under-slab drain lines
Interior drain re-piping, August 2026. The slab was cut along the drain route, the old lines removed, and new PVC drain connections laid on gravel with stub-ups for the fixtures above.
Bedding the new basement drain run in gravel
Same August 2026 basement drain project: each fitting is supported and the run is bedded in clear gravel before restoration, so the slope set during installation does not move.
Running the new drain line along the basement wall
Same August 2026 basement drain project: the replacement run follows the original route where slope allowed, with new stub-ups placed for the fixtures being reconnected.

25-year workmanship warranty
Every job Tornado Plumbing & Drains completes in Toronto and the GTA — repair, install, replacement, drain work, sewer work, fixture work — is backed by a 25-year workmanship warranty. The written terms are provided with every quote. If our work fails within 25 years of the install date, we come back and make it right.
When a patch isn't enough and the whole run has to go
Patching one leak on a 50-year-old galvanized line or a polybutylene system usually just moves the next failure a few feet down the pipe. We start by tracing the material and condition of the supply throughout the home, then tell you honestly whether a single section repair will hold or whether the run is failing along its length and should be replaced. Where a leak is staining ceilings or feeding mold, we pair the repipe with leak detection so the source is confirmed, not guessed.
What you'll notice before a repipe
- Water staining or bubbling drywall on a ceiling or wall with no fixture above it, tracing back to a pipe run
- Pressure that drops noticeably when two fixtures run at once, or hot water that arrives weak and rusty-tinted
- A green or white mineral crust and bluish-green staining around copper joints, elbows, and solder seams
- Pipes that knock, tick, or hammer in the walls when a tap or toilet shuts off
- Pinhole drips that keep reappearing a few feet from the last one you had soldered or clamped
- A musty smell or warm spot on a floor or wall where a slow supply leak is wicking into framing
What's included
- Inspection of the supply piping to identify material (copper, galvanized, PEX, polybutylene) and the extent of failure
- A clear recommendation on section repair versus partial or whole-home repipe, with the new route mapped and access openings marked
- Shut-off, draining, and removal of the failed run, with wall and ceiling cuts planned to keep patching to a minimum
- New copper or PEX supply piping installed with proper supports, isolation valves, and dielectric unions where dissimilar metals meet
- Permit handling and connection work brought up to current Ontario plumbing code where the repipe scope requires it
- Pressure testing of the new lines, restoration of access openings, and the work area cleaned on completion
- Written 25-year workmanship warranty on the repipe
Repiping is the right call when:
- Copper develops repeated pinholes on the same run.
- Polybutylene grey plastic fittings are leaking.
- Galvanized supply has lost most of its inside diameter.
- Renovation is opening walls anyway.
- Multiple section repairs are no longer cost-effective.
- Insurance has flagged old supply piping.
Section repair vs. whole-home repipe
| Situation | Best path |
|---|---|
| Single pinhole, otherwise sound copper | Section repair |
| Repeat pinholes on one run | Repipe that run |
| Polybutylene throughout the home | Whole-home repipe |
| Galvanized supply with low pressure | Whole-home repipe |
| Mixed-material plumbing from past renovations | Repipe the worst sections, plan rest |
Repipe cost
Pricing depends on length, fixture count, access, and material (copper or PEX). Section repipe of a single failing run is the lower range. Whole-home repipe is significantly higher and usually scoped against a renovation or major plumbing replacement project.
What to share when you call
- Pipe material and approximate age.
- Pinhole, leak, or pressure history.
- Renovation plans (open walls help).
- Photos of any visible failures.
- Whether the home is occupied during the work.
- Permit and inspection scheduling.
Toronto context
Repiping a Toronto home is usually cheaper than the customer expects when planned alongside other renovation work — drywall already open, cabinets out, floor lifted. We sequence the repipe with the renovation schedule so the disruption stays in one window.
What to confirm before approving repipe
- Material choice (copper or PEX) should be explained, not assumed.
- Drywall opening and patch scope should be documented.
- Pressure test should happen before walls close up.
Useful info on the call: pipe material, age, leak history, and renovation timing.
Frequently asked questions
Copper or PEX — which is better?
Both have advantages. Copper is more familiar, supports brazed joints, and has a long track record. PEX installs faster, costs less, handles freeze better, and works with fewer fittings. Both are code-accepted in Toronto.
How long does a whole-home repipe take?
Most residential repipes complete in 2 to 5 days for plumbing work, plus drywall patch time. Larger or finished homes take longer.
Will I have water during the repipe?
There are short windows when sections are off, but we plan around fixture access so the household can function. Whole-home repipes usually have an overnight period without water.
Is polybutylene a real problem?
Polybutylene (grey plastic, 1980s/90s) has a known failure pattern at fittings. If your home has it, planning replacement is usually wise.

Sharon Muszynski
May 2025“I highly recommend Serhiy. I have used him several times, and he always does quality work. He recently replaced a toilet, faucet, and house shut-off valve, all of which had leaks and were faulty. He knows what he is doing - He is licensed, experienced, efficient, and pays attention to details. His pricing is very fair, and unlike some others, the price doesn't go up based on the area you live in. All this is hard to find in professionals. Someone honest (he won't fix things that don't need repair to create work) and who takes pride in a job well done. I will definitely call him again for future plumbing needs.”

June 2020“I can’t recommend Tornado plumbing enough. Sergei and his team are literally the best. Sergei always provides the best recommendations and gives you his honest opinion. He doesn’t over sell and gives you the best advice. I had to have my main valve change which was something we had discussed a while ago from another service I had hired him for. The shut off valve was old and had lead component. I knew from past experience that anytime I needed to turn it on or off, it would start leaking. There was also a lead pipe leading underground. I made the decision to change all the lead pipe as opposed to just changing the shut off valve because it would eventually need to be changed regardless. Sergei dug from the front of my house to the water valve in my basement with minimal interruptions to my tenants, and minimal mess. This speaks to his attention to detail. He goes over and beyond my expectations. Thank you Sergei and Tornado Plumbing.”

August 2022“Tornado Plumbing and Drains did an excellent job replacing my old drains and correcting some very old plumbing in my old house in only 2 days. Peter was very thorough in evaluating and explaining in detail the problems with the drains and how they would be repaired. He was extremely patient in answering all of my concerns. The team showed up on time, protected the work areas and did an excellent job with the final clean-up. They are assisting me with the rebate for the valve also. The cost for the work was very reasonable and several thousand dollars less than two other companies. I have already recommended Tornado to several friends and recommend them without reservation.”
