Water Main Repair

The Line That Brings Water In

Your water main is the pressurised line running from the city shut-off at the property line into your home. Unlike a drain, it is always under pressure, so a fault does not wait for you to run a tap. It leaks continuously.

The usual culprits in Toronto are old galvanised or lead service lines, corrosion at the joints, ground movement, and freeze damage on shallow runs. The first sign is often a water bill that jumps for no reason, or a soft, permanently damp patch in the lawn.

Flood Guard locates, repairs and replaces water mains across Toronto and the GTA, including lead line replacement and trenchless options that leave your driveway intact.

Signs of a Water Main Problem

Watch for an unexplained rise in your water bill, a drop in pressure at every fixture rather than just one, damp or unusually green patches on the lawn between the street and the house, water pooling on the driveway, discoloured or rusty water, or the sound of running water when every tap is off. Any of these warrant a look. A water main leak does not fix itself and the ground it saturates is the ground your foundation sits on.

Repair or Replace

A single clean break on an otherwise sound copper line can be repaired. A corroded galvanised or lead line that has already failed once will fail again, and the sensible answer is replacement. We give you an honest assessment either way, with a written price, and we will tell you plainly when a repair is the better value. Where the run allows we use trenchless replacement, pulling the new line through the existing route so your driveway, walkway and landscaping stay intact.

Lead Service Lines

Many Toronto homes built before the mid-1950s still have lead service lines. The City replaces its portion up to the property line, and the homeowner is responsible for the section from there into the house. Replacing only one half leaves you with lead in the ground. We handle the private-side replacement, coordinate the timing with the City where we can, and pull the permits the work requires.

What Our Customers Say About Us

Real reviews from real customers across the Greater Toronto Area.

Called Flood Guard at 10pm on a Saturday when our basement drain backed up. They had a technician at our door within 45 minutes. Very professional, and the price was exactly what they quoted.

Scarborough Mark Thompson

We had a recurring clog that two other plumbers could not fix. Flood Guard did a camera inspection, found the root cause, and repaired it permanently. Honest company.

Mississauga Priya Sharma

Flood Guard installed a backwater valve after our basement flooded. The crew was punctual, explained everything clearly, and finished in one day. Highly recommend.

FAQ

How do I know if my water main is leaking?

A water bill that rises with no change in use, low pressure at every fixture, or a permanently damp patch in the lawn between the street and the house are the three classic signs.

Do I have to dig up my driveway?

Often not. Where the route and soil allow, we replace the line trenchlessly by pulling the new pipe through the old route, needing only a small pit at each end.

Who pays, me or the City?

The City is responsible up to the property line. The section from there into your house is the homeowner’s. We handle the private side.

How long does the work take?

A straightforward repair is usually a single day. A full replacement typically takes one to two days depending on the run length and the surface being crossed.

Do you handle the permit?

Yes. Water main work requires a permit and a city inspection, and we arrange both as part of the job.
