Toilets are simple machines with a handful of parts that wear out over time. A running tank, a weak flush, a handle that sticks or a slow leak at the base are all common, and they're especially common in Markham's 1990s and 2000s subdivisions, where builder-installed toilets have now been in daily use for many years.
Most toilet problems can be fixed without replacing the whole fixture. We diagnose what's actually wrong, repair it with quality parts and let you know honestly if the toilet itself is at the end of its life.
Toilet Repair Around Markham
When a subdivision is built, the same toilets are often installed in every home on the street. That means many Markham homeowners in neighbourhoods like Wismer and Angus Glen are now seeing the same wear at the same time: flappers that no longer seal, fill valves that hiss, and handles that stick. Swapping these parts is usually straightforward and brings an older toilet back to reliable operation.
Toilets in basement apartments and second suites deserve particular attention. A running toilet in a tenant's unit may go unreported for a long time, quietly adding to the water bill. If you're a landlord, a quick check of the toilets when you service the unit can pay for itself.
Hard water also leaves mineral deposits in the rim jets and siphon holes, which weakens the flush over time. We can clean those out as part of a repair.
Signs You Need Toilet Repair
Your toilet probably needs a repair if you notice:
- It runs constantly or refills on its own. Usually a worn flapper or a faulty fill valve letting water leak into the bowl.
- A weak or incomplete flush. Low tank water, a chain issue or mineral buildup in the rim holes can reduce flushing power.
- Water around the base. A failed wax ring or loose closet bolts can let water seep under the floor.
- The toilet rocks. A wobbly toilet can break its seal and should be reset before damage spreads.
- Cracks in the tank or bowl. Hairline cracks can leak slowly. Visible cracks usually mean replacement.
- Slow tank refill. A tired fill valve or partially closed supply valve can make refilling take ages.

Toilet Repair FAQs
Why does my toilet run by itself every so often?
That's often called phantom flushing. Water is slowly leaking from the tank into the bowl, usually past a worn flapper, and the fill valve tops it up.
Is a running toilet a big deal?
It wastes water continuously and can noticeably increase your bill. It's usually an inexpensive repair.
When should I replace rather than repair a toilet?
Cracks in the porcelain, repeated problems despite repairs, or a very old, inefficient toilet are good reasons to consider replacement.
Can a leaking toilet damage my ceiling?
Yes. A failed seal at the base can leak into the floor structure and show up as a stain on the ceiling below.
Do you repair dual-flush toilets?
Yes. Dual-flush mechanisms use different parts, and we service them along with standard toilets.
