How can I tell if I have a hidden water leak in my Newmarket home?

A few reliable signals point to a hidden leak before it becomes visible damage. Your water bill climbs without any change in usage. You hear running water somewhere in the house when everything is shut off. There's a soft or discoloured section of drywall, or paint is bubbling away from the surface. Musty smell in a room that shouldn't have moisture. Floors feel spongy near a bathroom or kitchen. A quick check: turn off every tap and water-using appliance, then watch your water meter for 15 to 20 minutes. If the meter is still moving, water is going somewhere it shouldn't. That's worth a call. Our licensed plumbers can conduct a comprehensive leak detection assessment and pinpoint the source before it causes further damage.

What should I do first if a pipe bursts in my Newmarket home?

Shut off the main water supply right away. In most Newmarket homes, the main shut-off valve is in the basement near the front foundation wall, on the supply line just before the water meter. A ball valve has a lever handle; turn it 90 degrees so it sits perpendicular to the pipe. A gate valve has a round handle; turn it clockwise until it stops. Once the water is off, shut down your water heater at the breaker or the gas valve so it doesn't run dry. Open a faucet on the lowest floor to drain pressure from the lines. Move anything electrical or valuable away from the affected area, and photograph the damage before cleanup starts. Your insurer will want documentation. Then call us. We carry the parts and fittings on the truck to handle burst pipe repairs on the same visit, day or night.

Are frozen pipes common in Newmarket, and how do I prevent them?

Yes, frozen pipes are among the most frequent emergency calls we receive in the Newmarket area between January and March. Pipes inside garages, along exterior walls, and in crawl spaces are the highest-risk sections because they get the least heat from the living space. To reduce risk: insulate exposed pipes in unheated areas using foam pipe sleeves, which are inexpensive and effective. Open cabinet doors under kitchen and bathroom sinks during cold snaps to let warm air circulate around the supply lines. Keep your thermostat no lower than 13°C when you leave for more than a day. If you're away for an extended winter trip, have someone check the home or shut off the main and drain the lines. Disconnect and drain garden hoses before the first freeze every fall. If you've had frozen pipes in the same spot more than once, the underlying problem hasn't changed. We can rework or relocate the vulnerable section to prevent it from becoming a recurring issue.

What are the signs that my Newmarket home might have polybutylene pipes?

Poly-B piping was widely installed in Ontario homes built roughly between 1978 and 1995. York Region has a lot of housing stock from that era. You can often spot poly-B by looking at the pipes visible near your water heater, under sinks, or in the utility room. The pipe is usually grey and flexible, with acetal plastic fittings, though some installations use metal fittings. Warning signs that poly-B is deteriorating: water pressure that's dropped gradually over a year or two, discoloured or cloudy water, evidence of past pinhole leaks at fittings, or soft spots under flooring near supply lines. If your home falls in that build window and you haven't had a supply line inspection, it's worth knowing what's in the walls. Our licensed plumbers can confirm whether you have poly-B, assess the condition of the system, and outline your options for poly-B replacement before a fitting fails and causes serious water damage.

Can a small drip really cause that much damage?

A pinhole leak in a supply line loses more water than it looks like. A drip that adds up to just 10 drops per minute wastes roughly 3,000 litres per year. What matters more than the volume, though, is where the water goes. A drip inside a wall cavity flows down through the insulation, pools on the bottom plate, wets the subfloor, and creates a persistently damp environment where mould can grow. Mould can begin developing within 24 to 48 hours of water exposure on porous material. A small leak caught early is a one-hour repair. A small leak left for six months can mean drywall removal, mould remediation, insulation replacement, and subfloor repair, costs that add up to many times the plumbing fix. The sooner a leak gets diagnosed, the smaller the job stays.

How does Mr. Rooter's upfront pricing work for pipe repairs in Newmarket?

We don't price jobs over the phone because every property is different. A pipe repair in a 1960s Gorham-College Manor home with galvanized lines is a different job than the same repair in a 1990s Aurora subdivision with PEX. Your plumber arrives, assesses the situation in person, and gives you a written quote before any tools are taken out. The price is flat-rate, meaning it reflects the job, not the clock. No overtime charges apply, day or night. For larger projects of $1,000 or more, payment plans and financing options are available, subject to credit approval. That includes major work like full pipe replacement, sewer line repairs, or water service line replacement. Contact us or request an estimate to schedule a licensed plumber who'll give you a clear answer on what the repair involves and what it will cost.

What Causes Leaking Pipes in Newmarket Homes?

Newmarket's climate puts real stress on residential plumbing. Winter temperatures regularly drop to -15°C or colder, and pipes running through unheated spaces like garages, crawl spaces, and along exterior walls are the first to freeze. When water freezes inside a copper or PEX line, the expanding ice pushes against the pipe wall. Copper splits at the joint or along a straight run. PEX is more forgiving but will still fail at a fitting or connector under enough pressure. Frozen pipes don't always leak immediately. The crack waits until the thaw, and then it opens up fast.
Newmarket's water supply has a hardness of roughly 170-190 mg/L, which falls in the hard-to-very-hard range. That mineral load accelerates wear inside your plumbing system. Scale builds up on the inner walls of older copper supply lines, reducing flow and increasing pressure at the fittings. Over time, that mineral deposit traps moisture against the pipe surface, promoting corrosion, especially at solder joints and where copper meets brass fittings. If your home was built between the late 1970s and mid-1990s, there's a real chance the supply lines behind your walls are polybutylene. Poly-B piping degrades from the inside out when exposed to chlorine in the municipal water supply, and York Region's water is chlorinated. The pipe walls become brittle, and fittings fail suddenly, sometimes without any visible warning.
Older homes in areas like Gorham-College Manor or Central Newmarket may still have galvanized steel supply lines. Galvanized pipe corrodes from the inside over decades, narrowing the interior diameter and eventually rusting through. Corrosion marks around fittings, discoloured water from the hot tap, and reduced pressure at upper-floor fixtures are all signs your galvanized lines are past their service life.

How We Find and Fix Pipe Leaks in Newmarket Homes

Most leaks aren't visible. They're behind drywall, under slabs, inside ceiling cavities, or buried in the crawl space. Guessing where a leak is by cutting open walls costs time and makes a mess. Our licensed plumbers use a proper diagnostic process before any repair work begins.

Sewer camera inspection locates hidden damage in drain and sewer lines without excavation. We run a waterproof camera down the line to identify cracks, root intrusion, offset joints, and deteriorating pipe sections at the exact location, so repairs are targeted rather than exploratory. For supply line leaks, pressure testing isolates which section of pipe is losing pressure, pointing us to the leak before we open anything up. Acoustic listening equipment can detect water movement inside walls and beneath concrete when the leak is producing sound, but there are no visible signs yet.

Once we find the leak, the repair depends on what we find. A split copper fitting gets cut out and replaced. A failed poly-B connection is replaced with PEX or copper pipe, which is the permanent fix rather than a patch. For sewer line damage, we offer trenchless options where conditions allow, resulting in far less disruption to your yard or landscaping. If a burst pipe has already caused water damage, we document the cause thoroughly because you'll need that detail for your insurance claim.

Every repair starts with an on-site assessment and upfront flat-rate pricing. You see the cost before we start. No overtime charges apply, whether we're there at noon on a Tuesday or 2 AM on a Saturday.
