A faucet repair in Thornhill typically costs $150 to $400, and a running toilet repair $75 to $300. In a home built between the 1960s and 1980s, the part is usually cheap; the question is whether the whole fixture is worth keeping.
These are general market estimates for York Region, not a quote. Most of the jobs fall in the lower half of each range, because a dripping faucet is usually a worn cartridge or O-ring and a running toilet is usually a flapper or fill valve. What makes Thornhill a little different is the age of the houses. Real estate listings put most of Thornhill's homes in the 1960 to 1980 building window, with more built in the 1980s, so plenty of kitchens and bathrooms still have fixtures that have been working for decades. That changes the useful question from "what does the repair cost?" to "is this fixture still worth repairing?"
Faucet repair: parts are cheap, access is the variable
A standard cartridge or O-ring swap on a kitchen or bathroom faucet is the cheap end of the $150 to $400 range. Plumbers and handymen in the GTA commonly bill about $75 to $150 an hour, and a faucet job tends to take one to two hours including diagnosis. The cost climbs when the faucet is old enough that the parts are discontinued, when mineral buildup has seized a fitting, or when the shutoff valves under the sink will not close. Those valves are the quiet problem in an older house. A valve that has not been turned in thirty years can leak or refuse to seal when you finally use it, and then a ten-minute faucet job also includes replacing the valve.
If the faucet is a single-handle model that has dripped through two repairs, replacing the faucet is usually the better use of money than a third cartridge. The fixture itself is only part of that cost; the labour to remove and reinstall it is the same whether the new faucet is basic or fancy.
The five-minute toilet test before you call anyone
York Region's water conservation page gives a simple test for a leaking toilet. Drop a dye tablet or a few drops of food colouring in the tank, do not flush, and wait about five minutes. If colour shows up in the bowl, water is leaking past the flapper. The same page says a leaking toilet can waste up to 200,000 litres of water a year, and often you cannot hear it. It also recommends replacing old, worn-out flappers.
That test is useful for two reasons. It tells you the problem is the cheap kind before a plumber arrives, and it gives you something concrete to describe on the phone. Most running-toilet calls come down to a flapper, a fill valve or a float, which is why the repair range ($75 to $300) sits below a faucet's.
Repair or replace: where a Thornhill toilet's age matters
The Ontario Building Code has required 6-litre toilets in new construction since 1996, and a 4.8-litre limit has applied to new construction since 2012, according to Halton Region's water efficiency guidance. A toilet installed in a 1960s or 1970s Thornhill house is therefore very likely a high-volume model, if it has never been replaced. That is not a reason to rip it out on its own. It is a reason to ask the question when a repair comes up.
- Repair it when the problem is a flapper, fill valve or float, and the tank and bowl are intact.
- Think about replacing it when the tank or bowl is cracked, the toilet rocks on the floor, or the same repair has come back more than once.
- Budget accordingly: a standard replacement typically runs $450 to $900 installed. A swap in the same spot takes the same plumbing, not new pipes.
Timing changes the price more than the part does
Regular daytime service in the GTA typically runs $90 to $175 an hour. After-hours, weekend and emergency calls commonly run $200 to $350 an hour, sometimes with a call-out fee on top. A slow drip or a running toilet rarely needs an emergency visit. Shutting the valve under the toilet or sink stops the water, and the repair can wait for a normal appointment. The exception is water you cannot stop: a burst supply line or a leak that will not shut off with the local valve is an actual emergency.
Permits and licensing on either side of Yonge Street
Thornhill sits across the Vaughan and Markham border at Yonge Street. For this kind of work, the two cities line up. Markham's published list says replacing existing taps, tubs, toilets or sinks needs no permit, and Vaughan's list likewise exempts replacing existing fixtures. Adding new plumbing where none existed is different and does need one, so moving a toilet or adding a sink is a call to your own city's building department. Plumbing is a compulsory trade in Ontario, so the person doing anything beyond a simple fixture swap should hold plumber certification; our guide on how to check whether a contractor is licensed shows where to look it up.

Rhodex can send a vetted craftsman; you can request a fixed price at https://rhodex.ca/get-a-quote.html?from=faucet-toilet-repair-cost-thornhill. Booking a normal daytime appointment keeps the price near the low end.
What to do this week
Run the dye test on every toilet in the house, and open each shutoff valve under the sinks and close it again to see whether it holds. Then you will know whether you have a $75 to $300 fix or a replacement to plan for, and you can book it as a regular appointment instead of a Saturday-night call.
