Reliable Pipe Work You Can Count On
From new plumbing installations, frozen pipe repairs to emergency pipe repairs, McPipe Plumbing provides dependable service across Thornhill, Vaughan, Richmond Hill, Markham, and the GTA. Whether you’re renovating, adding new fixtures, or dealing with a burst pipe, we make sure your home’s plumbing system runs safely and efficiently — no shortcuts, no surprises.
Professional Pipe Installation
Every new fixture or appliance depends on proper piping. If the pipes aren’t installed correctly, even the best fixtures can fail. We handle:
-
Water line replacement & installations for kitchens, bathrooms, and laundry rooms
-
Pipe extensions or rerouting for renovations and basement finishes
-
Replacement of old or corroded copper or galvanized pipes
-
Installation of water supply lines for dishwashers, ice makers, and outdoor taps
-
Pressure-tested connections to ensure long-term performance
We use high-quality materials — including PEX, copper, and PVC — and make sure every connection is secure and built to Ontario plumbing code.
Pipe Repair Services
When a pipe leaks, cracks, or bursts, fast action matters. We provide same-day pipe repair and replacement for homes and small businesses throughout the GTA.
We fix:
-
Leaking pipes behind walls or ceilings
-
Burst pipes caused by freezing or corrosion
-
Damaged joints or fittings
-
Water stains or damp drywall from hidden leaks
-
Reduced pressure caused by internal blockages
If the damage is minor, we repair the affected section. If the pipe is older or weakened, we’ll replace it fully to prevent future issues.
Leak Detection & Hidden Pipe Problems
Some leaks are obvious, while others hide behind walls or under flooring. You might notice higher water bills, musty smells, or damp spots that won’t dry.
We use non-invasive leak detection tools to locate and repair the problem before it causes damage.
If your home has older materials like galvanized steel or early copper, small leaks can quickly become major breaks. We can inspect your lines and suggest preventive replacements before that happens.
Local Examples
-
Thornhill: Replaced a leaking copper line in a finished basement without cutting into the wall — the joint had failed from age.
-
Vaughan: Rerouted sink and dishwasher supply lines during a kitchen remodel, pressure-tested before cabinetry went in.
-
Richmond Hill: Responded to a burst pipe in a laundry room during a cold snap; repaired the damaged section and added insulation.
-
Markham: Upgraded a main indoor supply line to improve water flow throughout an older home.
Emergency Pipe Repairs
Burst pipes and leaks don’t wait for business hours. Our team provides same-day and after-hours emergency pipe repair across the GTA. We’ll locate the leak, stop the water safely, and restore your plumbing as quickly as possible.
Frozen Pipe Repairs
Cold Ontario winters can be tough on plumbing. When temperatures drop, exposed or poorly insulated pipes can freeze and crack, leading to leaks or full pipe bursts once the ice thaws. McPipe Plumbing provides fast, reliable frozen pipe repair services throughout Thornhill, Vaughan, and across the GTA.
We commonly see frozen pipe issues in:
-
Basements and crawl spaces
-
Exterior walls
-
Laundry rooms and utility areas
-
Garages and additions
-
Vacant or under-heated homes
If a pipe has frozen, it’s important not to force it or try unsafe thawing methods. That can make the damage worse.
How We Handle Frozen Pipe Issues
When you call us for a frozen pipe, we focus on safety first, then long-term reliability.
Our process typically includes:
-
Locating the frozen or cracked section of pipe
-
Safely shutting off the water supply if needed
-
Repairing or replacing the damaged pipe section
-
Testing for leaks once the line is restored
-
Adding insulation or recommendations to help prevent future freezing
If the pipe has already burst, we’ll act quickly to stop the water and limit damage to your home.
Signs a Pipe May Be Frozen
Call us right away if you notice:
-
No water coming from a faucet
-
Reduced water flow in one area of the home
-
Frost on exposed pipes
-
Strange sounds when turning on taps
-
Water damage after a sudden thaw
Catching a frozen pipe early can prevent a much larger repair later.

Do you replace old galvanized or copper pipes?
Yes. We can replace aging materials with new, reliable PEX or copper to prevent corrosion and improve water flow.

Look for damp spots, bubbling paint, or musty smells. We can use moisture meters and inspection tools to confirm the source without unnecessary demolition.

Absolutely. We install or reroute lines for new sinks, dishwashers, laundry rooms, and basement bathrooms.

WHAT OUR CLIENTS ARE SAYING

Great job with our kitchen pipes!
Knowledgeable, prompt, clean and fairly-priced thorough service- that’s what you’ll get when you go with McPipe Plumbing! Ethan came on time (and that’s a big plus), knew exactly what needed to be fixed and set to work. He he told us what he was doing in simple terms and was very helpful when we had questions. We are definitely going to hire him again to install a new sink and redo the bathroom pipes. I highly recommend you call him for all your plumbing needs!
