Water Heater Repair & Replacement in Toronto & the GTA

A water heater that leaks from the tank body is finished — no repair exists for a corroded tank, and anyone offering one is selling you time you do not have. A leak at a fitting, valve or the T&P relief is a different matter and is usually a straightforward repair. The first thing we do on a leak call is determine which of those you have.

When replacement is the answer, the choice between a conventional tank, a power-vented tank and tankless depends on your venting, your gas line capacity and how you actually use hot water. Tankless is excellent for high simultaneous demand but frequently needs a larger gas line and a dedicated vent, which belongs in the quote rather than in a surprise on install day.

Most water heater calls come down to one of four things: a failed thermocouple or igniter on a tank unit, sediment insulating the bottom of the tank so the burner cannot transfer heat, a failed mixing valve giving you lukewarm water at every tap, or scale in a tankless heat exchanger that has cut flow to the point where the unit modulates down. All four look identical from the shower, and all four have different fixes and very different costs.

Tank age matters more than any other factor. A leaking tank is not repairable — once the glass lining fails, water is escaping through steel and the only outcome is replacement, usually sooner than you would like. We check the anode rod, the drain valve and the relief line on every visit so you get warning ahead of a failure rather than a wet basement floor as the notification.
