Top Toronto plumbing services for leaks, clogs and Pipe Repairs

Toronto homeowners dealing with leaks, clogs, and pipe repairs have several plumbing options across different service models

TORONTO’S HOUSING STOCK is old – much of it predates modern drain standards – and a burst pipe, stubborn clog, or slow leak can show up without warning on any homeowner’s radar. Knowing which plumber to call before water is already spreading across your basement floor genuinely matters. This guide breaks down the top Toronto plumbing services for leaks, clogs, and pipe repairs so you can compare options by what actually counts: scope, availability, and track record.

When a Leak, Clog, or Burst Pipe Strikes in Toronto

The city runs on a mix of aging clay sewer lines, cast-iron stacks, and storm seasons that keep getting worse, so plumbing emergencies aren’t a rare occurrence here. Tree roots crack lateral lines. Years of grease quietly accumulate in kitchen drains until the sink just quits. A January temperature swing splits a pipe joint nobody knew was failing.

In those moments, the fanciest website doesn’t save you. What matters is whether a licensed plumber picks up at 2 a.m., whether they can pinpoint the problem without gutting a wall, and whether you get a clear price before anyone touches a wrench. The five companies below were chosen based on service scope, operating history, verifiable credentials, and customer feedback available as of 2026.

1. Premier Plumbing

Premier Plumbing is a licensed plumbing and basement waterproofing company based in East York, covering homes, condos, and commercial properties across the Greater Toronto Area 24 hours a day, seven days a week.

Where it fits: Premier Plumbing handles the full range of drain cleaning, hydro jetting, camera inspections, trenchless pipe repairs, water heater replacement, leak detection, backwater valve installation, and interior or exterior waterproofing under one company, which means a flooding problem doesn’t require coordinating two separate contractors. Its waterproofing work carries a 25-year transferable workmanship warranty that stays with the home at resale, and it manages City of Toronto building permits and basement flooding subsidy paperwork as part of that service. The company holds a 4.9 out of 5 rating from 540 HomeStars reviews, an A+ BBB rating (accredited since March 2025), and has completed 2,500+ projects. A residential in-home diagnosis is priced at $39.95, with all other work quoted on site and approved before anything starts. Staff is licensed, WSIB certified, and TSSA approved. An Elite Membership Plan at $249 a year adds priority scheduling, an annual underground drain camera inspection, and extended warranties up to 20 years.

2. Dr. Pipe Drain and Plumbing

Founded in 1992 by Maxim Osadchyi, Dr. Pipe Drain and Plumbing is one of the longer-running licensed plumbing operations in the GTA, now with offices serving Toronto, Hamilton, and Ottawa.

Where it fits: The company covers drain repairs, trenchless drain repairs, plumbing installations, indoor pools, and fire sprinkler systems. It’s available 24/7 and carries a structured warranty package (one year on plumbing, five years on rough-ins, ten years on waterproofing, and twenty years on underground drain work), which is worth comparing directly when a large drain job is on the table. Dr. Pipe holds a 4.9-star Google Maps rating, is BBB Accredited since March 2010, and serves a broad service area including Toronto, Markham, Mississauga, Richmond Hill, Vaughan, and Scarborough, among others. The company is also cleared to work with government agencies and high-security clients. Pricing is upfront and direct.

Worth checking: Service scope is weighted toward drain and underground work; homeowners looking for waterproofing, water heater service, or fixture installation as a bundled offering may find the scope narrower than some alternatives.

3. Mr.Rooter

Established in 1970, Mr. Rooter Plumbing has grown into one of the largest plumbing and drain franchise networks in North America, with more than 250 locations across the United States and Canada.

Where it fits: The Toronto franchise provides emergency plumbing, drain cleaning and repair, sewer line repair, and plumbing inspections. Flat-rate pricing is the company’s main differentiator. Customers know the cost before work begins, and the company offers complimentary in-home estimates. Mr. Rooter earned the Entrepreneur Franchise 500 ranking as the number-one plumbing franchise for both 2024 and 2025, which signals consistent franchise-level operational standards. For residential and commercial customers who want predictable pricing from a nationally recognized brand, it’s a reasonable pick.

Worth checking: As a franchise operation, service quality and response times can vary by territory. The company’s size is its selling point for brand consistency, but local, owner-operated plumbers sometimes offer tighter accountability on individual jobs.

4. Delta Plumbers

Delta Plumbers Inc. has been operating out of Toronto since 1947, making it one of the oldest plumbing companies on this list, with two locations and a focus on residential and commercial work across Canada.

Where it fits: The company handles toilet, bathroom, and sink installations, drain cleaning, kitchen and bathroom plumbing, and emergency services available day or night. Owner Tony Ayam runs the business with an emphasis on clear communication, honest recommendations, and long-term fixes rather than pushing replacements, a practical approach for homeowners dealing with older fixtures or systems they want to extend rather than replace outright. Customer testimonials on the site speak to that service style.

Worth checking: Delta Plumbers doesn’t publish third-party review scores or BBB accreditation in publicly available information, and no formal case studies or client references appear on the site, which makes independent verification of performance harder than with some other options here.

5. Leaside Plumbing

Leaside Plumbing & Heating is a locally owned Toronto company on Wicksteed Ave that has been running since 1985, staffed by fully licensed and insured plumbers covering plumbing, heating, and natural gas piping.

Where it fits: The company serves both residential and commercial clients across East York, Riverdale, the Beaches, Rosedale, Scarborough, and Etobicoke, seven days a week for urgent repairs and routine inspections. Services span faucet repairs, toilet installations, drain cleaning, boiler maintenance, and waterproofing. Leaside has a genuinely distinct approach: it was the first Toronto plumber to focus exclusively on repairs, deliberately avoiding larger projects to stay available for immediate calls. That means it won’t try to sell a homeowner a full replacement when a repair does the job. The company doesn’t publish pricing publicly.

Worth checking: With four reported employees, capacity is limited compared to larger operations. Homeowners dealing with a large-scale job (full waterproofing, commercial drain work, or a multi-unit building) may find Leaside better suited to repair calls than major installations.

What Plumbers Actually Charge in Toronto

Toronto plumbing pricing varies by job type, urgency, and the scope of the repair. Most companies don’t publish flat price lists, but the City of Toronto market gives some general ranges worth knowing.

Drain cleaning typically runs $250 to $600 depending on the method. Snaking is at the lower end, hydro jetting at the higher. Camera inspections add $150 to $400. Water heater replacement (tank, gas or electric) generally lands between $1,200 and $2,500 installed, including removal of the old unit. Backwater valve installation, which qualifies for the City of Toronto Basement Flooding Protection Subsidy Program, ranges from $1,000 to $4,000 or more depending on access and excavation. Full exterior waterproofing is a larger project, with pricing varying significantly based on foundation length, depth, and whether parging is included.

Most companies charge emergency rates after hours. So an 11 p.m. Sunday call costs noticeably more than a weekday morning appointment. Some fold that into a flat service fee; others tack a percentage onto the labour rate. Ask about after-hours surcharges before the plumber shows up, every single time.

Upfront pricing models, where the cost is locked before work starts, exist at several companies on this list and are a meaningful protection against bill shock on a stressful day.

Bottom Line

Toronto homeowners dealing with leaks, clogs, and pipe repairs have several solid options across different service models: large franchise networks with standardized pricing, established family-run companies with deep local roots, and full-service operations covering everything from drain cleaning to basement waterproofing under one roof. The right fit depends on the job type, the neighbourhood, and how much weight you put on factors like warranty length, independent reviews, or after-hours availability. Checking verified ratings, confirming licensing and insurance, and getting a price in writing before work starts are still the best ways to avoid a bad experience, regardless of who gets the call.
