Editorial Review
Our Take on Plombier Montréal
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.

iAbout service coverage
Coverage is as the business describes it, cross-checked against where its recent documented work is. A company will often travel beyond the areas listed here for a large job and decline a small one at the same distance, so confirm your address before scheduling.
About Plombier Montréal
Drains are the spine of this company's offering. The service list on its website runs through unblocking drains and toilets, camera inspection, testing pipe for deterioration, excavation and replacement of failed lines, and installation of backwater valves, which in Montreal is less of a luxury item than it sounds. Add water heater installation and repair, general leak work, pressure problems and commercial plumbing, and you have a firm that can handle both the 2am emergency and the planned job you have been putting off since spring.
The emergency side is presented as the front door. Call, describe the problem and the address, and the team decides whether it is an immediate dispatch, a scheduled repair or a fuller evaluation. On arrival, the stated approach is to find the source, secure the area and limit damage before proposing a fix, with a written estimate if the work turns out to be larger than a quick repair. That sequence matters more than it sounds. The gap between a cleared blockage and a dug-up basement floor is enormous in cost, and a contractor who stops to explain the difference before the excavator arrives is doing you a favour.
Housing stock drives the work here. Large parts of the island were built with clay or cast iron sewer laterals, and the freeze and thaw cycle, root intrusion from mature silver maples and a century of settling all take their toll. Rosemont, Verdun, NDG and the Plateau are full of duplexes and triplexes where a single shared lateral serves several units, so one root mass can flood the lowest apartment. Spring melt and the sudden summer downpours that overwhelm the combined sewer system are the classic backup triggers, which is why the city has pushed backwater valve installation through its subsidy programs. Anyone shopping for a plombier montr al should ask directly whether the contractor handles the municipal permit and inspection steps that come with valve work and any excavation touching the public portion of the line, because those steps are not optional and they affect the timeline.
Winter changes the calculus too. Frozen and split supply lines in unheated crawl spaces, garages and old rear annexes are a January staple, and water heater failures cluster in the cold months when tanks are working hardest. A firm with genuine round-the-clock coverage is worth more in February than in July.
On fit: this looks like a good match for owners and property managers dealing with recurring backups, slow drains, sewer odours or a tank that has given out, and for commercial clients who need someone to attend a building outside business hours. It looks like a weaker match if your project is a full repipe, a bathroom renovation with new rough-in, or a boiler and hydronic heating job. Those are not emphasised anywhere in the material. A specialist heating contractor is usually the better call for radiator systems, which are common in older Montreal buildings.
A few practical checks before you book. Confirm that the plumber holds a current RBQ licence and is a CMMTQ member, since Quebec regulates the trade tightly and you want that verified for your own file rather than assumed. Ask how emergency rates differ from daytime rates, whether there is a callout or diagnostic fee, and whether that fee is credited against the repair. Ask for the camera footage if a line inspection leads to a recommendation for excavation, and get the recommendation in writing. Two phone numbers circulate for this business, a 514 number on the website and a 438 number on the Google listing, so use whichever you reached a human on and keep a record of it.
Compared with the alternatives, the market splits between franchise operations with dispatch centres and uniform pricing and smaller independent crews who quote job by job. Plomberie Pro-Drain sits closer to the independent end while advertising franchise-style availability, which is a reasonable position if the response is as quick as claimed. The Google rating of 4.2 from 26 reviews, read on September 25, 2026, suggests mostly satisfied customers with some variation in experience, and 26 reviews is a small enough sample that reading several of them yourself is worth the five minutes. For anyone comparing a plombier montr al on drains specifically, the depth of the drain service list is the clearest point of difference here.

Plombier Montréal FAQs
Do they actually come out at night and on weekends?
The company advertises a 24/7 emergency service on its own website, covering leaks, blocked drains, overflowing toilets, sewer backups and water heater failures. Availability on any given night is not something a profile can guarantee, so call and describe the problem, the address and what you can see. Ask what the after-hours rate is before anyone is dispatched, since emergency pricing in the trade is normally higher than daytime pricing.ã
Which parts of Montreal do they cover?
Most of the island, according to the neighbourhood list on their site. Named areas include Ahuntsic, Anjou, Cartierville, Lachine, LaSalle, Saint-Laurent, Saint-Léonard, Verdun, Westmount, Hochelaga-Maisonneuve, Île des Soeurs, Côte-des-Neiges, Montréal-Nord, Notre-Dame-de-Grâce, Outremont, the Plateau-Mont-Royal and Rosemont. Off-island pages exist for Laval, Longueuil, Brossard, Boucherville, Terrebonne, Repentigny and Saint-Jean-sur-Richelieu.
How good are their reviews?
The Google Business Profile showed 4.2 stars from 26 reviews when it was read on September 25, 2026. That is a respectable average, though 26 is a small enough number that it is worth reading the individual comments, especially any that mention pricing or how a larger job was handled.
Do they install backwater valves?
Yes, clapets anti-retour are listed as a core service, along with drain excavation and repair. In Montreal these valves protect basements against sewer backups during heavy rain, and boroughs have historically offered subsidies toward installation. Ask whether the company handles the permit, the inspection and any subsidy paperwork, and whether the quote includes reinstating the concrete floor slab.
Which phone number should I use?
Either may work, but they differ. The Google listing carries +1 438-476-5486 while the website displays 514-298-1911. Try the website number first if you are contacting them during business hours, and note which one connected you. There is also a contact form on the site that lets you attach a photo of the problem.
What should I do while waiting for the plumber?
Shut off the water if you safely can, either at the main or at the valve for the affected fixture. Move anything valuable away from the water, and keep clear if it is near an outlet or an appliance. Avoid improvised repairs or chemical drain products, which can make a blockage or a leak worse and complicate the diagnosis when the plumber arrives.
Do they handle commercial buildings?
Yes. The company states it serves residential, commercial and industrial clients, with a dedicated commercial plumbing service page. For a building with tenants, ask about scheduling outside trading hours, access arrangements and whether they can provide a written report after a drain camera inspection for your records or your insurer.
Is Plombier Montréal licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.
What areas does Plombier Montréal serve?
Montreal, Lasalle, Saint-Laurent, Outremont. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Plombier Montréal offer emergency service?
Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
