Plumber in Ontario
Plumbing work in Ontario covers everything from a dripping faucet to a full re-pipe of a century home in Toronto's east end. This category includes 133 businesses handling drain cleaning, water heater and tankless system swaps, sump pump installs, gas line hookups for stoves and dryers, backwater valve installs (common in areas prone to basement flooding), and the burst-pipe calls that spike every January when a cold snap hits. Some outfits are one-person operations who know their neighborhood cold; others run a fleet of trucks and can dispatch same-day across a whole region.
Before you hire, check that the plumber holds a valid Ontario license (look for the certificate of qualification or the company's TSSA registration if gas work is involved), carries liability insurance, and gives you a written estimate before starting. Ask how they price emergency calls versus scheduled ones, since after-hours rates can run much higher. A plumber who pulls permits for water heater or backflow work, rather than skipping that step, is generally one who stands behind the job.

Common questions about plumber
- How much does a plumber cost in Ontario?
- Most plumbers charge a service call fee plus hourly labor, often landing between $90 and $150 per hour once the call fee is factored in. A simple faucet repair might run $150-$300, while a water heater replacement typically falls between $1,200 and $2,500 depending on the unit and whether venting or gas line work is needed. Emergency or overnight calls usually cost more than scheduled daytime visits.
- How often do I need a plumbing inspection or service?
- Most homeowners only call a plumber when something breaks, but a yearly check of the water heater, sump pump, and main shutoff valve catches small issues before they turn into emergencies. Older homes with cast iron or clay drain lines benefit from a camera inspection every few years to spot root intrusion or corrosion early.
- What should I expect during a typical plumbing visit?
- The plumber should assess the problem, explain the likely cause, and give you a price before doing the repair rather than after. For anything beyond a quick fix, expect a written quote covering parts and labor. Reputable plumbers clean up after themselves and walk you through what they did and why.
- How do I judge whether a plumber did good work?
- Look for a fix that solves the root cause, not just the symptom (a drain that's still slow a week later is a red flag). Check that any permits required for gas or water heater work were actually pulled, and confirm the plumber offers a warranty on both parts and labor, usually 90 days to a year depending on the job.
