10 Best Plumbers in Montreal, QC

Our top 10 plumbing companies in Montreal

Each entry explains why the company was selected, what it does well and what to weigh before hiring.

  1. Plumbing Montreal 24/7

    after-hours plumbing emergencies across Greater Montreal when you need someone dispatched tonight5.0(49 Google reviews)Best for after-hours plumbing emergencies across Greater Montreal when you need someone dispatched tonight    Rank01

    Why we picked them

    The dispatch model is stated openly on the website, which counts for something, and the flat 5 from 49 Google reviews suggests the handoff between coordinator and contractor is going smoothly for most callers. We would still treat the self-reported dispatch times and job counts as claims rather than data. Ask for the contractor's RBQ number and the after-hours rate before anyone drives over, and you will get the benefit of round-the-clock coverage without the usual guesswork.

    What we like

    • Live bilingual phone coverage advertised around the clock, every day of the year
    • Preliminary price range given before dispatch, with the final price confirmed on site before chargeable work begins
    • 5 out of 5 from 49 reviews on its Google Business Profile, read September 25, 2026
    • Covers both emergency repairs and coordinated bathroom, kitchen and basement renovation plumbing
    • Service area spans Montreal, Laval, Longueuil and surrounding suburbs

    Things to consider

    • A dispatch and coordination platform, not a plumbing company with its own crews, so the person arriving is an independent contractor
    • Licence, insurance and warranty details rest with the individual contractor and should be confirmed directly
    • Dispatch times, job counts and service-area figures are self-reported on the company website
    • 49 reviews is a modest sample, so read them individually rather than relying on the average alone

    Services

    • Emergency plumbing
    • Fixture installation

  2. Plomberie Urgence Montreal (PUM)

    overnight drain backups and burst pipes in Montreal, Laval and the Rive-Nord4.9(692 Google reviews)11550 Bd Albert-Hudon, Montréal, QC H1G 3J6, CanadaBest for overnight drain backups and burst pipes in Montreal, Laval and the Rive-Nord    Rank02

    Why we picked them

    The combination of genuine 24-hour dispatch and a 4.9 average across 691 Google reviews is the reason this one is worth keeping on the fridge. It reads as a drain-and-emergency specialist first, which is exactly what most Montreal basements eventually need. Just settle the after-hours rate and whether diagnosis is billed separately before the truck rolls.

    What we like

    • Published 24-hour availability, seven days a week, with calls booked through an in-house dispatch centre
    • 4.9 rating from 691 reviews on its Google Business Profile, read September 25, 2026
    • Strong focus on drains: camera inspection, unclogging, smoke testing and excavation for water lines
    • Handles backwater valves, sump pumps and backflow device inspection, relevant to flood-prone Montreal basements
    • Takes residential, commercial and property-management work, including jobs involving insurance adjusters

    Things to consider

    • After-hours and holiday rates are not published, so confirm the hourly rate and any minimum charge on the phone
    • Built around emergency call-outs rather than planned renovation projects or design-led bathroom builds
    • The CAA-Quebec recommendation and member discount come from the company's own website and should be verified when booking

  3. Superior Plumbing & Heating of Montreal

    urgent plumbing and drain problems in older Montreal homes, at any hour4.8(131 Google reviews)3460 Rue Peel, Montréal, QC H3A 2M1, CanadaBest for urgent plumbing and drain problems in older Montreal homes, at any hour    Rank03

    Why we picked them

    The combination of published RBQ licence, genuine 24 hour cover and a service list that stretches from hydro jetting to heat pumps makes this a sensible first call when something has already gone wrong. The recent Google reviews are consistent and bilingual, which counts for a lot in this market. Just pin down the call-out fee and get the estimate in writing, because none of the pricing is published.

    What we like

    • Published hours list 24 hours a day, seven days a week, with same-day service advertised
    • RBQ licence number 5876-1974-01 published openly, plus stated CMMTQ membership
    • 4.8 from 130 reviews on its Google Business Profile, read September 25, 2026
    • Service range covers plumbing, drains, sewer and trenchless work plus furnaces, boilers and heat pumps
    • Recent reviews appear in both French and English
    • Written warranty of up to 90 days on service claimed on the website

    Things to consider

    • No rates published, so call-out and after-hours pricing must be confirmed on the phone
    • Part of a multi-city Canadian operation, which may cost more than a one-person local plumber on small jobs
    • The 90 day warranty referenced online applies to service labour, not to equipment
    • Some listed claims, such as crew size and years in business, come from the company's own website

    Services

    • Emergency plumbing
    • Drain cleaning
    • Water heater repair
    • Repiping
    • Sewer line repair
    • Leak detection

  4. Plomberie V.I.P.

    drain and sewer diagnostics in older Montreal buildings4.9(657 Google reviews)8135 R. Drolet #312, Montreal, Quebec H2P 2H6, CanadaBest for drain and sewer diagnostics in older Montreal buildings    Rank04

    Why we picked them

    The combination of a 4.9 rating across 657 Google reviews and a service list built around camera work, smoke testing and sewer cleaning points to a company that spends its days on the diagnostic end of plumbing, which is where Montreal's old laterals cause the most grief. The long daily hours are a genuine advantage for landlords and commercial tenants. Just pin down the after hours rate and the excavation restoration scope on the phone, because neither is published.

    What we like

    • 4.9 rating from 657 reviews on the Google Business Profile, read September 25, 2026
    • Long daily service window, 6 AM to 8 PM most days, with emergency response advertised
    • Diagnostic tools including camera inspection and smoke testing, not just mechanical clearing
    • Excavation and new pipe installation offered alongside repair work
    • Covers the island plus Laval and the Rive-Sud, including Ahuntsic, Rosemont, Villeray and Anjou
    • R.B.Q. licence number published on the company site for easy verification

    Things to consider

    • No pricing published online, so rates and after hours premiums have to be confirmed by phone
    • The website advertises 24/7 emergency while the profile lists 6 AM to 8 PM, worth clarifying before a late night call
    • Heating, ventilation and appliance work are not among the listed services
    • The Rue Drolet address appears to be an office suite rather than a walk-in location

  5. Plombier Urgence de Saint-Henri Montreal

    emergency drain and water heater call-outs in Saint-Henri and the Sud-Ouest4.8(22 Google reviews)4020 Saint Ambroise St, Montreal, Quebec H4C 2E1, CanadaBest for emergency drain and water heater call-outs in Saint-Henri and the Sud-Ouest    Rank05

    Why we picked them

    The service list and the address both point to a genuine Sud-Ouest specialist, and the drain, camera and backwater valve work is exactly what this housing stock demands. The 4.8 rating from 20 reviews read on September 25, 2026 is encouraging without being a large sample. We would want the 24/7 claim reconciled with the 6 AM to 11 PM hours on the Google profile before relying on a 3 AM call.

    What we like

    • Focused on the Sud-Ouest boroughs, with local knowledge of older Saint-Henri and Pointe-Saint-Charles housing
    • Broad drain capability including camera inspection, hydro-jetting and backwater valve installation
    • 4.8 stars from 20 Google reviews as read on September 25, 2026
    • Company states it is RBQ licensed and insured, with written guarantees on parts and labour
    • Long daily published hours, seven days a week, including early mornings

    Things to consider

    • The website advertises 24/7 service while the published Google hours read 6 AM to 11 PM daily; confirm overnight availability before relying on it
    • Twenty reviews is a small sample, so read the individual comments rather than the average
    • Service area is concentrated in the southwest of the island, so coverage elsewhere in Montreal is unclear
    • No published pricing, including after-hours call-out rates; ask on the phone

  6. Plomberie Montreal Supreme

    after-hours plumbing repairs in older central Montreal homes and small commercial units4.5(22 Google reviews)1025 Ave Van Horne, Outremont, Quebec H2V 1J4, CanadaBest for after-hours plumbing repairs in older central Montreal homes and small commercial units    Rank06

    Why we picked them

    A small, visibly active operation with genuine 24/7 positioning and a sensible Outremont base for the central boroughs. The 4.5 rating from 22 Google reviews is a decent signal rather than a strong one, so we would treat the phone conversation as the real vetting step, particularly on after-hours rates and licensing. For everyday residential repairs and small commercial work, it looks like a reasonable shortlist candidate.

    What we like

    • Published hours show 24 hours a day, seven days a week, backed by the same claim on its own site
    • Handles both residential and commercial plumbing, so it covers homes and small business premises
    • 4.5 rating from 22 Google reviews, read on September 25, 2026
    • Outremont address puts it close to the older duplex and triplex stock of central Montreal
    • States coverage across Greater Montreal including the North and South shores
    • Active Instagram, Facebook, X and LinkedIn presence showing recent project work

    Things to consider

    • Only 22 Google reviews, a small sample compared with larger Montreal plumbing firms
    • No pricing, call-out fee or after-hours rate is published, so ask before dispatch
    • Licence and trade association details are not listed on the profile
    • Response times to the far North and South shores will be longer than on the island

  7. Plomberie Drainville

    drain and pipe work in Montreal duplexes and triplexes4.9(57 Google reviews)6683 rue Jean-Talon Est, bureau 213Best for drain and pipe work in Montreal duplexes and triplexes    Rank07

    Why we picked them

    A 4.9 average across 57 Google reviews is a strong signal, and the published RBQ number and CMMTQ membership are the kind of detail that lets a reader verify something instead of taking it on faith. The multiplex experience is the differentiator worth paying for in central Montreal. Just get the after-hours rate and the scope of the free estimate confirmed on the phone, since neither is published.

    What we like

    • RBQ licence 5836-1882-01 and CMMTQ membership published openly, easy to verify
    • 4.9 rating from 57 Google reviews as read on September 25, 2026
    • Covers emergencies, drains, water heaters and full renovation rather than one narrow service
    • Stated experience with shared stacks and tight access in Montreal duplexes and triplexes
    • 24-hour emergency line and free estimates on all services, per the company

    Things to consider

    • No prices, call-out fees or after-hours rates published, so confirm by phone
    • Review volume is modest at 57, high average but a smaller sample than large franchises
    • Service beyond the core boroughs is confirmed address by address
    • Site leads in French with an English toggle

  8. Plomberie A+

    urgent drain, leak and water heater work in Montreal's older southwest housing4.9(186 Google reviews)3921 Rue Lanouette, Montréal, QC H4G 1B5, CanadaBest for urgent drain, leak and water heater work in Montreal's older southwest housing    Rank08

    Why we picked them

    The review record here is genuinely strong, and the reviews read like real jobs rather than prompted praise, which is not always the case in this trade. The honest read is that a solo plumber is excellent on the call-out and more variable on work that stretches across several visits, and the one critical review on file says exactly that, including the follow-up where it was put right. Get the scope and price in writing, verify the RBQ number, and it is a sensible call for urgent and mid-sized residential work.

    What we like

    • 4.9 from 186 reviews on its Google Business Profile, read September 25, 2026
    • Published hours show availability 24 hours a day, every day of the week
    • Calls reportedly reach the plumber directly rather than a dispatch office
    • Covers both emergency repair and renovation piping, plus camera inspection of buried lines
    • Company states prices are confirmed before work starts, with free estimates

    Things to consider

    • Appears to be a single-operator business, so scheduling on multi-visit projects can slip, as one detailed review describes
    • Advertised promotional prices are starting figures confirmed only after on-site assessment
    • RBQ licence, insurance and guarantee are the company's own claims and worth verifying directly
    • No after-hours or emergency surcharge is published, so confirm night and holiday rates by phone

  9. Matériaux de plomberie Ray-Jean inc.

    Why we picked them

    Well rated for a supply counter, with a 4.9 average from 159 Google reviews as of September 25, 2026, and a stated history going back to 1976. The value here is the repair-parts shelf and the advice that comes with it, which is exactly what old Montreal plumbing tends to need. Just go in knowing you are buying materials, not booking a technician.

    What we like

    • 4.9 rating from 159 reviews on its Google Business Profile, read September 25, 2026
    • Specialist focus on repair parts, useful for older Montreal plumbing
    • Family business since 1976 by its own account, now third generation
    • Delivery offered across Greater Montreal, South Shore and North Shore
    • Early 7:30 AM weekday opening suits trades loading up before first calls
    • Free quotes advertised for material orders

    Things to consider

    • A supply distributor, not a plumbing contractor, so no service calls or repairs
    • Closed Saturday and Sunday, with no listed after-hours option
    • Showroom visits are by appointment only according to the website
    • Website is in French and the company's history and experience claims are its own

  10. Plombier Montréal

    sewer backups, blocked drains and backwater valve work in older Montreal buildings4.2(26 Google reviews)Best for sewer backups, blocked drains and backwater valve work in older Montreal buildings    Rank10

    Why we picked them

    The drain and backwater valve focus is genuine, and in a city where combined sewers and hundred-year-old laterals cause most of the misery, that is the right thing to be good at. The 4.2 rating from 26 reviews is decent without being overwhelming, so read the reviews and get the estimate in writing before excavation is discussed. Sort out which phone number is current on your first call.

    What we like

    • Deep drain specialism covering unblocking, camera inspection, excavation and backwater valves
    • Advertises 24/7 emergency response for leaks, backups and overflowing toilets
    • Serves residential, commercial and industrial clients across most Montreal boroughs plus Laval and the South Shore
    • Stated process of securing the site and giving a written estimate before larger works begin
    • 4.2 rating from 26 Google reviews as read on September 25, 2026

    Things to consider

    • Two different phone numbers appear, a 514 on the website and a 438 on the Google listing
    • 26 reviews is a modest sample to judge consistency from
    • No licence, insurance or pricing details are published in the material reviewed
    • Little mention of repipes, renovation rough-in or hydronic heating work

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 Montreal

  • 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
