Best Plumbers in Toronto
A plumbing problem rarely happens at a convenient time. Whether you are dealing with a blocked drain, a burst pipe in January, or a water heater that stopped working overnight, finding a reliable plumber quickly matters.
Toronto has plenty of plumbing companies, but quality, pricing, and response times vary widely. Some specialize in drain work, others focus on residential repairs and renovations, and a handful offer around-the-clock emergency coverage across the GTA.
This guide covers nine real, currently operating plumbing businesses that serve Toronto homeowners. Each one has a track record you can verify through Google, HomeStars, or the Better Business Bureau before picking up the phone.
1. DrainWorks Plumbing
DrainWorks has been serving Toronto and the surrounding area since 1995, making them one of the more established names in drain and sewer work. They operate out of Etobicoke and cover the full city.
They handle clogged drains, hydro jetting, sewer camera inspections, and pipe replacement. Salaried staff rather than commission-based technicians removes the pressure to upsell. They back their drain clearing with a guarantee: clear it or you do not pay. Calling before noon generally gets you booked same-day.
2. Brothers Plumbing
Brothers Plumbing has been operating in the GTA since 1969, giving them one of the longest track records of any plumbing company in the city. That kind of longevity tends to reflect consistent workmanship and repeat customer loyalty.
They cover residential and commercial work: water heater servicing, sewer main blockages, backwater valve inspection, and drain repairs. Their 24/7 emergency line connects you to a real person at any hour. Getting a written quote upfront is a good idea, as their pricing tends to sit at the higher end of the market.
3. The Great Plumbing Co.
The Great Plumbing Co. has focused on residential plumbing in Toronto since 1989. The company built its reputation around flat-fee pricing: you agree on the cost before anyone starts work, with no hourly billing surprises.
Their service list covers most things a homeowner is likely to run into: burst pipe repair, frozen pipe thawing, leak detection, water line repairs, drain cleaning, sewer repairs, and kitchen and bathroom plumbing.
They run a 24-hour live phone line and keep fully stocked trucks on the road. Well reviewed on HomeStars and Google, they cover Toronto and a wide band of the surrounding GTA including Markham, Oakville, and Scarborough.
4. Drain King Plumbers
Drain King Plumbers operates as a 24/7 emergency service. They answer calls at any hour, dispatch quickly, and put a real person on the phone rather than routing you through an answering machine.
They are well reviewed across Google and HomeStars, with a large volume of feedback pointing to reliable response times and clear communication. Drain cleaning and emergency repairs are their primary focus, covering Toronto and the broader GTA.
5. True Service Plumbing
True Service Plumbing is a family-owned company serving Toronto homeowners and property managers across the GTA. Their work spans general repairs, drain cleaning and camera inspection, bathroom and kitchen installations, and coordination for condo and multi-unit buildings.
They offer 24/7 emergency coverage and are praised for clean, organized work on both small repairs and larger renovation plumbing. Reviews on Google highlight their communication and willingness to explain what needs to be done before starting.
6. Premier Plumbing
Premier Plumbing is based in Toronto's east end and has been in the trade for roughly two decades. They focus on residential plumbing with same-day availability and transparent pricing.
Water heaters are one of their calling cards. They offer same-day and emergency hot water tank replacement and back all installations with a one-year labour warranty. Other services cover faucet and toilet repairs, drain issues, and bathroom or kitchen plumbing for renovations. They carry a 24/7 emergency line and are well reviewed on Google.
7. New Canadian Drain and Plumbing
New Canadian Drain and Plumbing has been locally owned and operated since 2002. They specialize in drain cleaning, drain repair and replacement, waterproofing, and leaky basement remediation, making them a strong choice for the water intrusion problems common in older Toronto homes.
They offer 24/7 emergency service and aim to arrive within an hour for urgent situations across the GTA. Their focus on drain and waterproofing work means the technicians have deep familiarity with the problem types they handle.
8. Royal Plumbing Services
Royal Plumbing Services has operated from their Dufferin Street location in Toronto since 2000 and holds BBB accreditation going back to 2007. They handle drain and plumbing work for both residential and commercial customers across the GTA.
Services include pipe and drain unclogging, sewer cleaning, plumbing repairs, and on-call emergency coverage around the clock. Their longevity and accreditation give homeowners a straightforward way to check their standing before booking.
9. Mr. Rooter Plumbing of Toronto
Mr. Rooter is a franchise operation whose technicians are registered with Skilled Trades Ontario. The Toronto location serves homeowners and commercial clients across the city with drain cleaning, water heater replacement, sewer line repair, and general plumbing.
They offer upfront flat-rate pricing and a workmanship warranty. Licensed plumbers are available around the clock for emergencies, and free in-home estimates make it easy to get a baseline price without committing.
What to Look For in a Plumber
Experience and Expertise
A plumber who has worked in Toronto for years will have seen the pipe materials, drain configurations, and building types common to local homes. Ask whether the company has handled your specific problem before, particularly for sewer line work, basement waterproofing, or large-scale renovation plumbing.
Licensing and Insurance
All plumbing work in Ontario must be performed by a licensed plumber registered with Skilled Trades Ontario. Confirm the technician carries a valid Certificate of Qualification before work begins. A professional company will also carry liability insurance and workers' compensation coverage, and they will confirm both without being asked twice.
Reviews and References
Google and HomeStars are the most useful platforms for checking Toronto plumber reviews. Look for companies with a meaningful volume of feedback across several years rather than a handful of recent entries. For a larger job such as a sewer line repair or full bathroom rough-in, asking for references from similar recent projects is entirely reasonable.
Tips for Hiring a Plumber in Toronto
Get Several Quotes
For any job beyond a straightforward repair, two or three quotes give you a realistic sense of market pricing. Ask each company to provide a written quote itemizing labour and materials separately, as this makes comparisons more meaningful and protects you if the final invoice does not match what was discussed.
Confirm Timelines and Warranties
Before work begins, get a clear answer on how long the job will take and what warranty covers the labour. A one-year labour warranty is fairly standard for installation work. Ask what happens if the problem recurs within the warranty period, and make sure the answer is in writing.
Ask About Emergency Service
Not every plumber who lists a phone number online answers calls after hours. Ask directly what their after-hours process looks like. Knowing this before a pipe bursts at midnight makes a stressful situation much easier to manage.
