What the fixture is telling you
A faucet drip, a toilet that hisses between flushes, a puddle at the base of the bowl and a handle that spins without a result each have a different cause. The plumber works from the symptom to the part, so describe what you hear and see.
A fixture leak differs from a pipe leak. A drip at the spout or the tank is a fixture job. Water appearing on a wall or ceiling near the fixture belongs on Leak repair, where the pipe behind it is the question.
Repair or replace
Repair keeps the fixture and swaps the worn part: a cartridge, a seat, a set of seals inside a toilet tank. Replacement removes the old fixture and installs a new one, with new supply lines and often a new shut-off valve. The Canada-wide figures from HomeStars show the gap: fixing a toilet runs $200 to $400, installing a new toilet $260 to $683. For faucets, installation runs $195 to $455, and the Ottawa list gives a wider $200 to $3,800 for faucet repair and installation, since a kitchen with three faucets is a larger invoice.
Ask which option the company recommends. For an older model, parts can cost close to a new fixture.
What the visit looks like
The plumber checks the fixture, the shut-off valves under it and the supply lines, then works on the part that failed. On a toilet that includes the sealing parts inside the tank and, for base leaks, the flange seal below the bowl. On a faucet it means the cartridge or valve behind the handle, matched to the brand.
A corroded shut-off valve is a common snag. A shut-off that will not close fully can stop a quick repair, because the plumber needs the water off. That adds a valve to the quote, usually mentioned before the work starts.
What moves the price
Four things separate a small bill from a large one:
- The fixture. A common faucet costs less to repair than a designer model with imported parts.
- Access. A pedestal sink or a toilet against a tiled wall takes longer to reach.
- Hidden damage. A base leak that has soaked the subfloor adds floor repair.
- Call terms. HomeStars lists Canadian service calls at $140 to $475 including the first hour, and trip fees from $65 to $390. A Mr. Rooter Ottawa article says some firms add a diagnostic fee and a separate call-out for after-hours work.
Permits and rules
The City of Ottawa lists replacing kitchen or bathroom cabinets as exempt from a building permit, provided the plumbing fixtures remain in the same location. Faucet and toilet swaps go unnamed on that page. Moving a toilet, a sink or a drain is new plumbing, and the company should say who handles the permit question. The page on Plumbing permits in Ottawa covers it, and Drain cleaning covers a toilet that blocks.
In writing
Ask for the fixture, the part, the labour and the total with tax on one page. If you supply the fixture, the quote should say so, and whether labour carries a written warranty. The Consumer Protection Act rule that an estimate can rise by 10% at most applies to contracts with an estimate, so check whether yours is an estimate or a fixed price.
Who you are dealing with
A cartridge, a flapper or a wax seal gets fitted by a plumber from an independent Ottawa company. Ottawa Plumbing Desk hands over your fixture details and photos; that company calls you, says repair or replace, and quotes it.
Questions to ask the company
- Is the price for a repair of the existing fixture, or for a replacement with a new one?
- Who supplies the faucet or toilet, and what happens to the price if I choose it?
- Does the quote include a new supply line and shut-off valve if the old ones are corroded?
- Is there a minimum charge or trip fee on top of the labour?
- What happens if the leak is in the wall behind the fixture?
Have this ready for the call
- The fixture brand and model, usually on a sticker inside the tank or under the sink
- Photos of the drip, the base and the shut-off valves under the fixture
- How old the fixture is and when the problem started
- A clear floor around the toilet and an empty cabinet under the sink
- The replacement faucet or toilet in the box, if you already bought one
Questions people ask
Is it cheaper to repair a leaking faucet or replace it?
A repair on a newer faucet is usually the smaller bill, since the plumber replaces one worn part. Older or discontinued models can have no parts to match, and then replacement costs less over time. The Canada-wide guide lists $195 to $455 for a new faucet installed.
Why does my toilet keep running after it flushes?
A toilet that fills again and again after a flush usually has a worn part inside the tank that no longer seals. The plumber checks the sealing parts and the fill setting in a set order. HomeStars puts Ottawa toilet repair at $344 on average.
The base of my toilet leaks. Is that a big job?
Water at the base usually comes from the seal between the toilet and the drain flange, or from the tank connection above. The plumber lifts the toilet to check the flange and the floor below. If the floor is soft, the job grows, so photos help the quote.
My faucet drips only when it is hot. What does that mean?
A drip on one side points to the part that controls that line, so the rest of the faucet is probably sound. A plumber matches the cartridge or valve to your model. Give the brand and the date it began, and the company can say whether a repair or a swap makes sense.
Can I swap a vanity and keep the same plumbing?
Yes, and the City of Ottawa lists replacing kitchen or bathroom cabinets as exempt from a building permit when the plumbing fixtures remain in the same location. If the sink or drain moves, tell the company, since that is new plumbing work.
How do I stop a toilet from overflowing while I wait?
Close the small valve on the wall or floor behind the toilet and leave it unflushed. If water keeps rising, close the main shut-off in the basement, then send the request.
