How much does plumbing cost in London?
Most Canadian homeowners pay $150-$450 for a common plumbing repair - clearing a drain, or swapping a toilet or faucet - on top of a $90-$350 service-call fee, with plumbers billing about $80-$175 an hour. Bigger equipment jobs cost far more: a replacement water heater runs roughly $1,100-$6,500 depending on tank versus tankless, and a sump pump $500-$2,500.
In London, ON, typical quotes tend to track the Canadian average, so the table below shows these national figures unchanged.
What moves the price: The low end is a common repair like clearing a drain or swapping a toilet or faucet; the top end is equipment work like a tank or tankless water heater or a sump pump.
| Project | Typical cost in London |
|---|---|
| Service call / diagnostic visit (covers travel + first 30-60 min) | $150 $90 to $350 per visit |
| Standard hourly labour rate (regular hours) | $125 $80 to $175 per hour |
| Drain cleaning / snaking (sink, toilet or main line) | $275 $150 to $600 per project |
| Toilet installation / replacement (incl. removal and disposal) | $350 $200 to $500 per project |
| Faucet installation / replacement (kitchen or bathroom) | $300 $150 to $455 per project |

What changes the price of plumbing in London
- Bundling jobs: combining several small tasks into one visit usually saves 10-20% because the plumber reuses the trip and setup time.
- Timing of the visit: emergency, after-hours, weekend and holiday calls typically run 1.5x to 2x normal rates, with emergency call-outs often $180-$300 per hour.
- Quality of the fixture or equipment: a builder-grade toilet or faucet costs far less than a high-end or touchless model, and gas vs electric or condensing vs non-condensing water heaters swing the price by thousands.
- Home age and access: older homes with corroded shut-off valves, worn toilet flanges, outdated pipe materials, or tight crawlspaces and finished basements add labour time.
- Scope of the actual fix: a quick drain snake costs a fraction of a camera inspection plus hydro-jetting or a main-line dig; a straight water-heater swap costs far less than one needing new gas line, venting or electrical.
- Permits and inspection: some municipalities require permits or a safety inspection (for example TSSA sign-off on gas work in Ontario), which add fees and a bit of time.
How plumbing prices vary across Canada
Big metros cost more. Toronto and Vancouver run roughly 15-25% above the national ranges - Vancouver plumbers commonly bill $120-$180/hr and Toronto $100-$200/hr versus an $80-$150 national norm, and Toronto drain cleaning is quoted $250-$600 versus $150-$350 nationally. Calgary, Edmonton and Ottawa land about 10-15% above baseline. Montreal, mid-size cities and the Prairies are near the national average, and rural and Atlantic Canada often sit slightly below.

How much does a plumber charge just to show up?
A service call is usually $90-$350, which typically covers travel and the first 30-60 minutes of diagnosis. After that, most Canadian plumbers bill $80-$175 per hour. Evening, weekend and emergency visits cost noticeably more.
Is a tankless water heater worth the extra cost over a tank?
Tankless costs roughly 2 to 3 times more upfront (about $2,500-$6,500 installed vs $1,100-$3,000 for a tank), but it lasts around 20 years instead of 10-12 and uses roughly 20-30% less energy. It pays off if you plan to stay in the home long term; a straight tank swap is the cheaper choice if budget is the priority.
Why is my drain cleaning quote so different from my neighbour's?
It comes down to the blockage. A simple sink or toilet snake is often $150-$300, but a deep main-line clog that needs a camera inspection or hydro-jetting can run $400-$600 or more. Where you live matters too, since big-city rates run higher.
