How much does drain cleaning cost in Ontario? (2026)

Prices checked September 2026. Drain prices are mostly about which line is blocked and how the plumber gets into it. A kitchen sink branch is small pipe close to the fixture. A main sewer line is 100 mm (4 inch) pipe running under the basement floor to the city connection, and it may be full of tree roots, grease or a collapsed section. The same visit can cost $200 or $2,000 depending on which one you have.

How much does it cost to unclog a drain?

Clearing one fixture drain with a hand or machine auger typically costs $150 to $350 from a plumbing or drain company in the GTA, with most quotes around $225 to $300. Kitchen sinks sit at the top of that range because grease builds up along the whole branch; bathroom sinks and tubs, usually hair, are quicker. A toilet auger visit is similar, about $140 to $380.

These ranges are built from 2025 to 2026 price lists and cost guides published by Toronto-area plumbing and drain contractors, compared across at least three companies per job. Most are flat rates per drain rather than hourly.

What does drain cleaning cost on Doyo?

On Doyo, Drain Cleaning is $259.60. That is the full price, Doyo’s service fee included; nothing is added at checkout, and your card is only charged when the job is marked complete. Tell the Doyo agent which drain is slow, since when, and whether other fixtures are backing up too, so the job is booked as what it really is.

If the plumber finds the blockage is further down, in the main line, or needs a camera to see it, they have to put the new figure to you in the order chat and wait for your yes before doing more. Plumbers on Doyo hold a Certificate of Qualification (306A), and Doyo checks it before they are offered plumbing work.

How do I know if it is a main line blockage?

If several fixtures are slow at once, or water comes up through the basement floor drain when you run the washing machine or flush a toilet, the blockage is almost certainly in the main line rather than one fixture. That is a bigger job: expect the main-line price, not the sink price. One slow sink with everything else fine is a branch clog.

When is a camera inspection or hydro-jetting worth it?

A camera inspection is worth paying for when the same drain blocks more than once in a year, when an auger brings back roots, or before you buy an older house. It shows whether the problem is a one-off clog or a cracked, sagging or root-filled pipe that will keep blocking. Hydro-jetting, which scours the pipe with high-pressure water, makes sense for grease-lined kitchen lines and heavy scale; for a simple hair clog it is overkill.

What changes the price of drain cleaning?

1. Which line. A fixture branch is quick; a 100 mm main line under the floor takes more equipment and more time.
2. Access. A clean, reachable cleanout roughly halves the work compared with pulling a toilet to get into the line.
3. What is in the pipe. Hair and soap clear fast; grease, scale and tree roots take longer or need jetting.
4. Time of day. After-hours calls often carry a premium of 50% or more.
5. Repeat blockages. If the drain keeps blocking, you are paying for a diagnosis, and a camera may save money over repeat visits.
6. Pipe condition. Older clay or cast-iron sewer laterals in pre-1960s homes are more likely to have roots or breaks that turn a cleaning into a repair.
7. City side vs private side. The part of the sewer lateral under the road usually belongs to the municipality; many plumbers stop at the property line.

How do I avoid being overcharged for drain cleaning?

• Ask for a flat price per drain before the work starts, and what happens if the auger does not clear it.
• Under Ontario’s Consumer Protection Act, 2002, a business cannot charge you more than 10% above its estimate unless you agree to a new price first.
• Ask for the camera footage if you are told a pipe needs replacing. A reputable company will show you the break or the roots.
• Get a second quote before agreeing to excavation or relining. Those jobs run into the thousands.
• In Toronto, check the Basement Flooding Protection Subsidy before a backwater valve install: it covers 80% of the invoice up to $1,600 per valve, if a permit is taken out and the work is inspected.
• Ask whether the quote includes tax, so you compare like with like.
