What toilet repair involves
A toilet is simple, which is good news. The tank holds a fill valve, a flush valve with a flapper or a canister seal, and an overflow tube. Under the bowl sit a wax ring or foam seal, the closet flange and two closet bolts. Almost every complaint traces to one of those.
| Symptom | Usual cause |
|---|---|
| Runs or refills on its own | Worn flapper, or fill valve set too high |
| Weak or double flush | Low tank water level, blocked rim jets, partial clog |
| Rocks on the floor | Loose bolts or a broken flange |
| Water at the base | Failed wax seal, or a sweating tank |
| Hissing | Fill valve not shutting off |
We match the parts to your model where we can. A generic flapper on a toilet designed for a specific one often leaks again within weeks.
Why North York houses need it
North York homes hold every generation of toilet, from heavy older 13-litre units to modern 4.8-litre and dual-flush models. Older shut-off valves under the tank are often multi-turn stops that have not moved in years and drip once they are turned. In houses with original cast iron or galvanized drains, a toilet that rocks may sit on a corroded flange that needs a repair ring rather than a new wax seal.
Moderately hard Toronto water leaves scale in the rim jets and on fill valve seals, which shortens part life.
Plumber's tip: A toilet trickling silently into the bowl wastes litres by the hour. Drip some food colouring into the tank and leave it fifteen minutes unflushed, and check the bowl. If the bowl turns colour, the flapper leaks.
How we write up the job
Each line on the order names the part, its brand where relevant, and what we saw. If the shut-off valve is seized, we tell you before we touch it, since it may need replacing. If the toilet itself is cracked, we say so and quote the repair and a replacement side by side.
Signs you should call
- The tank refills every so often with nobody using it.
- Water appears on the floor after a flush.
- The toilet moves when you sit down.
- You plunge it more than once a week.
- A sewer smell near the base.
Some of these you can try yourself; our leaflet on running toilet fixes walks through the easy ones.
Costs and what affects them
Parts are usually the small part of the bill. Time goes up when the toilet has to come off the floor, the flange needs repair, or the supply valve and line need replacing too. Older or discontinued models can need special-order parts. You see the price before the work, and if repair does not make sense against a new toilet, we say so plainly.

Your questions on this one
Should I repair or replace an old toilet?
Repair if the china is sound and parts are available. Replace if it is cracked, uses a lot of water per flush, or clogs no matter what.
Why does my toilet sweat?
Cold water in the tank meets warm, humid air. It is common in summer and is not a leak, though it can damage the floor over time.
