Signs you need toilet repair
Toilets tend to complain before they fail. You may hear the tank refilling on its own at night, see the handle needing a jiggle, or notice the bowl water level creeping up and down. A higher-than-usual water bill can be the only sign of a slow silent leak from tank to bowl.
Movement is another warning. A toilet that shifts when you sit on it has usually lost its seal at the flange, and water can seep into the subfloor long before a stain appears on the ceiling below.
How we approach it in Markham houses
We start with the simple tests: dye in the tank to check the flapper, a look at the fill valve height, and a check of the supply stop beneath the tank. Many Markham homes still have the original multi-turn stop valves, and those often weep or refuse to close fully. If that is the case we suggest replacing it while the water is off, so the next repair is easier.
For a rocking toilet, we lift the fixture, inspect the flange and the floor around it, and reset it on a new seal with proper closet bolts. If the flange is cracked or sits well below a newly tiled floor, we repair or extend it rather than stacking wax rings.
Clues pointing to toilet repair
- Tank topping itself up every few minutes with nobody near it.
- Bowl rocks when you sit or shift weight.
- Brown staining or soft flooring at the base.
- Water rising to the rim on most flushes.
Running, rocking and clogged toilets
| Symptom | Usual cause | Typical fix |
|---|---|---|
| Refills on its own | Worn or warped flapper | New flapper matched to the flush valve size |
| Hissing that does not stop | Fill valve set too high or failing | Adjust or replace the fill valve |
| Rocks or wobbles | Loose bolts or failed seal | Lift, inspect flange, reset on a new seal |
| Clogs often | Obstruction in trapway or low-flow design | Auger the trap; discuss replacement if chronic |
Some older low-flush models simply do not clear well, however well they are repaired. When that is true we will say so plainly, and toilet installation becomes the sensible conversation.
Before you call
- Try a plunger with a flange cup for an ordinary clog, but stop if water rises toward the rim.
- Lift the tank lid and note whether water spills into the overflow tube.
- Check whether the supply stop turns; if it is seized, tell us.
If a supply line has split rather than the toilet itself leaking, see our page on burst pipe repair. Homeowners in Milliken Mills and other older neighbourhoods often find several bathrooms worth checking at once.
Questions homeowners ask
A few answers to the things people wonder about while we work. Ask us anything else on the phone; a short description of the noise or the water level often tells us which parts to bring.
Markham note: village-core houses tend to hide cast iron and galvanized behind plaster, while Cornell and Box Grove builds run PEX to a manifold. We ask the year your house was built so the right fittings ride along on the truck.
Straight from the phone log
Is it worth repairing an old toilet?
Usually yes, if the china is sound and it clears well. Flappers, fill valves and seals are modest parts. Replacement makes more sense when the bowl is cracked or it clogs constantly.
Why does my toilet run for a few seconds every so often?
That is called ghost flushing, and it is nearly always a flapper letting water seep into the bowl until the fill valve tops the tank up again.
Can a rocking toilet damage the floor?
Yes. A broken seal lets small amounts of water out with every flush, which can soften the subfloor over months without being visible.

One call, a clear explanation, and work finished tidily before we leave.
