  1. Mr Rooter Plumbing of Mississauga ON

    urgent drain and sewer problems in Mississauga homes, any hour4.8(2618 Google reviews)281 Queen St S, Mississauga, ON L5M 1L9, CanadaBest for urgent drain and sewer problems in Mississauga homes, any hour    Rank01

    Why we picked them

    The review volume here is unusual, and an average of 4.8 across more than 2,600 entries is a reasonable signal that the day-to-day work lands well. A 24-hour line and a full drain and sewer kit make this a sensible first call for anything urgent. Just settle the after-hours premium and the warranty terms on the phone, because franchise pricing tends to sit above what a one-van independent charges.

    What we like

    • 4.8 Google rating from 2,618 reviews as of September 18, 2026, an unusually large sample
    • Published hours show a 24-hour line, seven days a week
    • Full drain and sewer capability including camera inspection, jetting and trenchless repair
    • Covers both residential and commercial work, including grease traps and backflow preventers
    • Says it has served Mississauga since 1995, so the branch is long established

    Things to consider

    • Franchise pricing generally sits above what a single-van independent charges
    • After-hours and weekend call-outs typically carry a premium, so confirm it before booking
    • Licensing, insurance and warranty terms are the company's own claims and worth verifying directly
    • Excavation on sewer laterals may involve city permits, so clarify what the quote includes

    Services

    • Emergency plumbing
    • Drain cleaning
    • Water heater repair
    • Sewer line repair

  2. Top 24/7 Plumbing

    after-hours drain and sewer emergencies in Mississauga homes5.0(117 Google reviews)6435 Erin Mills Pkwy, Mississauga, ON L5N 4H4, CanadaBest for after-hours drain and sewer emergencies in Mississauga homes    Rank02

    Why we picked them

    A 5.0 average across 117 Google reviews is hard to argue with, and the depth of the drain and sewer pages suggests this is where the company does most of its work rather than a list padded out for search engines. The genuinely useful thing on offer is availability at hours when most Mississauga plumbers are asleep. Confirm the after-hours rate and the permit question by phone, and use the number on the Google profile rather than the one in the website header.

    What we like

    • Published hours show the line open 24 hours a day, every day of the week
    • 5.0 Google rating from 117 reviews as read on September 18, 2026
    • Deep drain and sewer focus, including hydrojetting, camera inspection, rooter work and sewer repair
    • Covers both urgent repairs and planned installs such as water heaters, sump pumps and softeners
    • Stated service area extends to Toronto, Etobicoke, Vaughan, Burlington, Pickering, North York and Richmond Hill

    Things to consider

    • The website header lists an emergency number that differs from the Google profile number, so use the profile number
    • No pricing, call-out fee or after-hours rate is published, so confirm costs before booking
    • Large repipes and new-build rough-ins are not named in the service list and may be outside scope
    • Licensing and insurance are claimed on the company's own site but are not independently verified here

    Services

    • Emergency plumbing
    • Drain cleaning

  3. John The Plumber

    same-day drain cleaning and after-hours plumbing emergencies in Mississauga homes4.8(445 Google reviews)1164 Shamir Crescent, Mississauga, ON L5C 1L1, CanadaBest for same-day drain cleaning and after-hours plumbing emergencies in Mississauga homes    Rank03

    Why we picked them

    A 4.8 average across 445 Google reviews is a strong signal at that volume, and the reviews are unusually consistent about two things: the work gets done properly, and it is not cheap. We would call them for drains, sewer backups and water heaters, particularly outside normal hours, and get a second quote for anything non-urgent.

    What we like

    • 4.8 rating from 445 Google reviews as of September 18, 2026
    • Published hours list 24 hours a day, every day, for emergency calls
    • Dedicated drain cleaning division with snakes, augers and hydro jetting
    • Upfront job pricing and a two-year warranty advertised on its own site
    • Trading since 2006, per its website, with service across the western GTA

    Things to consider

    • Multiple reviewers note prices at the higher end for the area
    • Head office appears to be in Ottawa, so the Mississauga arm is one branch of a regional company
    • The profile does not list separate after-hours or call-out fee details
    • Focused on residential work rather than commercial or new-build installation

  4. Pipe Dreams Plumbing of Mississauga

    homeowners who need after-hours leak and drain help in Mississauga5.0(85 Google reviews)60 Bristol Rd E #237, Mississauga, ON L4Z 3K8, CanadaBest for homeowners who need after-hours leak and drain help in Mississauga    Rank04

    Why we picked them

    A flawless 5.0 across 85 Google reviews is a genuinely good record for a small residential plumber, and the service list is broad enough to cover most of what a Mississauga home throws up. The public detail is thin in places, with a Gmail contact and a suite-number address, so we would settle licensing, permits and the after-hours rate on the first phone call. Do that, and the round-the-clock availability is the real draw.

    What we like

    • 5.0 rating from 85 reviews on its Google Business Profile, read September 18, 2026
    • Published hours show availability 24 hours a day, seven days a week
    • Service list covers both emergency call-outs and planned work like repiping and renovation rough-ins
    • Site emphasises explaining options before work begins
    • Small-operation flexibility on appointment timing

    Things to consider

    • No licence, insurance or WSIB details are published, so ask for them directly
    • Primary written contact is a Gmail address rather than a business domain email
    • Listed address is a suite number, and the service radius across Peel is not stated
    • Pricing, call-out fees and after-hours rates are not published

    Services

    • Emergency plumbing
    • Drain cleaning

  5. Superior Plumbing & Heating of Mississauga

    same-day and overnight plumbing emergencies in Mississauga homes4.8(94 Google reviews)4020 Sladeview Crescent Unit 6, Mississauga, ON L5L 6B1, CanadaBest for same-day and overnight plumbing emergencies in Mississauga homes    Rank05

    Why we picked them

    The 4.8 from 94 Google reviews and genuine 24/7 hours make this a credible emergency call, and the combined plumbing and HVAC list saves a second phone call when a tank and a furnace fail in the same week. The trade-off shows up in the reviews themselves: at least one customer called it pricey while still rating the speed highly. Fine for urgent work, worth comparing quotes on anything you can schedule.

    What we like

    • 4.8 rating from 94 Google reviews, read on September 18, 2026
    • Published hours show genuine 24/7 availability, seven days a week
    • Plumbing and HVAC handled by the same company, from drains to furnaces and heat pumps
    • Trenchless sewer repair and Poly B replacement listed, both relevant to Mississauga housing stock
    • Company states upfront pricing and a warranty of up to 90 days on its work

    Things to consider

    • A published review describes the service as pricey, though praised the speed
    • Part of a multi-city brand, so you may not get the same technician twice
    • Arrival-time and no-surcharge claims come from the company's own site and are worth confirming when booking

    Services

    • Drain cleaning
    • Water heater repair

  6. DrainEx Plumbing of Mississauga

    evening and weekend drain clearing and leak call-outs in Mississauga homes5.0(71 Google reviews)3075 Ridgeway Dr Unit 212, Mississauga, ON L5L 5M6, CanadaBest for evening and weekend drain clearing and leak call-outs in Mississauga homes    Rank06

    Why we picked them

    The review record is genuinely good, and daily hours to 9 PM cover the evenings when drain problems tend to announce themselves. The mismatch between a Mississauga address and a Toronto-focused website, plus two different phone numbers, is the thing to clear up in the first minute of the call. Ask about licensing and the drain pricing structure and this is a sensible one to try for a clog or a leak.

    What we like

    • 5.0 rating from 71 reviews on its Google Business Profile, read September 27, 2026
    • Published hours of 7 AM to 9 PM seven days a week, including Sunday
    • Drain-led service list covering clogs, camera inspection and recurring blockages
    • Handles both residential and small commercial work, including rentals and multi-unit buildings
    • Covers leak detection, pipe repair and water heater work alongside drains

    Things to consider

    • The company's own website is written around Toronto service, so confirm Mississauga coverage for your address
    • The website lists a different phone number from the Google profile
    • Review count is modest compared with larger Mississauga plumbing firms
    • No pricing, licence numbers, insurance details or guarantees are published in the available information

    Services

  7. Rosedale plumbing

    after-hours drain, sewer and water heater emergencies in Mississauga5.0(64 Google reviews)776 Dundas St E, Mississauga, ON L4Y 2B6, CanadaBest for after-hours drain, sewer and water heater emergencies in Mississauga    Rank07

    Why we picked them

    The 5 out of 5 from 64 reviews, read on September 18, 2026, is a clean record, and the 24-hour posting plus a drain-and-sewer service list built for diagnosis rather than just clearing make this a reasonable first call for an after-hours Mississauga emergency. What we cannot see is pricing, and a company covering this much of Ontario from one listed address will inevitably be stronger in some areas than others. Confirm the call-out fee and the licence before the van is dispatched.

    What we like

    • 5 out of 5 from 64 reviews on its Google Business Profile, read September 18, 2026
    • Hours published as open 24 hours, seven days a week
    • Full drain and sewer ladder including camera inspection, hydro jetting and line repair
    • Trading since 2010 according to its own website, with claimed licensed and insured plumbers
    • Covers both residential and small commercial premises

    Things to consider

    • No pricing published, so call-out and diagnostic fees need confirming by phone
    • The Google listing number differs from the number on the company website
    • 64 reviews is a modest sample for a company advertising service across much of southern Ontario
    • Positioned for repair and emergency work rather than long-lead renovation project management

    Services

    • Emergency plumbing
    • Drain cleaning
    • Water heater repair

  8. Harb Plumbing

    drain and sewer work in older Mississauga homes, plus Kitec pipe replacement4.9(581 Google reviews)2400 Dundas St W Unit 6, Mississauga, ON L5K 2R8, CanadaBest for drain and sewer work in older Mississauga homes, plus Kitec pipe replacement    Rank08

    Why we picked them

    The service list reads like a company that has genuinely done this for decades, covering the awkward jobs, main sewer lines, Kitec replacement, backwater valves, that plenty of firms would rather hand off. A 4.9 average across 581 Google reviews is a lot of feedback for one Mississauga address, and it points to consistency rather than a lucky run. Get after-hours rates and permit responsibility confirmed on the phone before the truck is dispatched, and this is a sensible shortlist entry.

    What we like

    • 4.9 average from 581 reviews on its Google Business Profile, read September 18, 2026
    • Published hours show open 24 hours every day, with a marketed 24/7 emergency response
    • Handles specialist jobs many firms avoid, including main sewer lines, backwater valves and Kitec pipe replacement
    • Family-owned and trading since 1974 according to its own website
    • Design showroom on Dundas Street West lets you see fixtures before committing, by appointment
    • Covers both emergency repair and complete bathroom and kitchen renovation

    Things to consider

    • Call-out and after-hours rates are not published, so confirm them by phone before booking
    • Showroom visits are by appointment only, not drop-in
    • Service area spans Oakville through Hamilton, so travel time may affect response in outlying areas
    • No gas, HVAC or electrical work appears in the published service list

  9. TheRestorators Plumbing of Mississauga

    sewer backups and flooded basements needing plumbing and restoration together5.0(55 Google reviews)5105 Hurontario St #103, Mississauga, ON L4Z 0C9, CanadaBest for sewer backups and flooded basements needing plumbing and restoration together    Rank09

    Why we picked them

    The pairing of emergency plumbing with restoration and abatement is the real story here, and it is genuinely useful when a call involves water that has already spread. A perfect 5.0 from 55 Google reviews is encouraging, though the count is light for a business that traces itself to 1993, so we would lean on it alongside your own questions rather than on its own. Get the after-hours rate and the warranty terms in writing before anyone starts.

    What we like

    • Plumbing and restoration handled by the same company, useful after backups and floods
    • 5.0 Google rating from 55 reviews, read September 18, 2026
    • Published hours are 24 hours a day, seven days a week
    • Website dates the business to 1993, with nine GTA service areas listed
    • Abatement and mould remediation capability alongside pipe work

    Things to consider

    • Review count of 55 is modest relative to the claimed years in business
    • Mississauga address is a suite on Hurontario, with a Toronto head office listed on the website
    • No pricing, call-out fees or warranty terms published
    • Two different phone numbers appear across the listing and website

    Services

  10. Galaxy Plumbing Inc.

    drain, flood prevention and water heater work in older Mississauga homes5.0(282 Google reviews)55 Village Centre Pl, Mississauga, ON L4Z 1V9, CanadaBest for drain, flood prevention and water heater work in older Mississauga homes    Rank10

    Why we picked them

    A 5.0 average across 282 reviews is the sort of record that usually means consistent crews and careful follow-up, and the diagnostic services on offer back that up. The plumbing and HVAC combination makes this a sensible call for basement flooding and heating problems that turn out to be related. The Sunday closure is the one gap to plan around.

    What we like

    • 5.0 Google rating from 282 reviews as read on September 18, 2026
    • Plumbing and HVAC under one contractor, including commercial refrigeration
    • Camera inspection and leak detection offered as diagnostic services, not just repairs
    • Published 24-hour availability Monday through Saturday
    • Dedicated property management division for buildings and multi-unit sites

    Things to consider

    • Published hours show Sunday closed, despite the 24-hour emergency line advertised
    • No pricing published, so after-hours rates and call-out fees need confirming by phone
    • Financing and the twenty-plus years of experience are company claims, not independently verified here

This list was assembled from Google Maps results for the trade and city, then each company was written up from its own public profile. Positions follow Google's order and are not an editorial judgement until an editor reviews them.

How to choose a plumber in Mississauga

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope
