Describe the situation during the initial contact
You do not need to identify the defective part yourself. To help direct the request more effectively, provide:
- the address and neighbourhood where the work is needed;
- the type of building and the affected floor;
- the affected fixtures and the signs observed;
- the presence of active water, wastewater or an electrical hazard;
- access to the valves, water heater or main drain.
For an active leak or sewer backup, calling is the most direct way to communicate the urgency. The reviews displayed below this section describe individual experiences with SOS Plombiers or an assigned local company; response times, prices and work vary with each request.

Emergency service, repairs and installation
Priority plumbing services in Montreal
The plumber checks the cause, access to the pipes and the condition of the installation before proposing the work. This page summarizes the most common local needs; the service pages provide the technical details.
Blocked drains and sewer backups
One slow fixture does not point to the same cause as several drains backing up together. Depending on the location, the work may require mechanical drain clearing, high-pressure cleaning or an inspection of the main drain. See drain unclogging and service for a sewer backup.
Camera drain inspections
A camera can document a recurring blockage, roots, a collapsed section or damage in an accessible pipe. It complements the diagnosis without replacing it. Learn more about camera inspections of drains and pipes.
Water heaters and plumbing fixtures
Lack of hot water, a leaking tank, toilet, faucet, sink, bathtub or shower: the plumber checks the connections, valves, drainage and compatibility with the installation. View the water heater installation, repair and replacement service.
Backwater valves and sump pumps
Protecting a basement depends on the configuration of the system and the source of the risk. A backwater valve, a sump pump or a drainage correction may be recommended after an inspection.
Scheduled work and commercial plumbing
Fixture replacement, pipe modifications, renovations, maintenance or plumbing needs in a business: the request is directed based on the timeline, access and scope of the project. View the plumbing services or commercial plumbing page.
Start with the symptoms
Which service is most likely suited to the problem?
Describe what you see, hear or smell. These details help determine the priority and required equipment without jumping too quickly to a specific repair.
Only one fixture drains poorly
The blockage may be located in the trap or the fixture’s drain pipe. Specify what has already been tried and whether the water eventually drains.
Several drains react together
Gurgling, water backing up or several affected fixtures may direct the inspection toward a stack or the main drain.
A stain or leak appears
Indicate whether the water flows continuously, while a fixture is being used or after rainfall. The source may be far from the visible stain.
The problem returns after drain clearing
A camera inspection or more thorough cleaning may become appropriate after confirming the access point and the affected pipe.
Prepare before calling: full address, type of building, floor, affected fixtures, presence of active water, access to valves and photos when the situation is stable.
Local realities
Service adapted to Montreal buildings
A house, plex, condominium and business do not have the same access conditions or shared systems. These differences can change how the water is shut off, how a pipe is reached or how the work is planned.
Houses, duplexes and triplexes
A drainage stack, water service line or shared shut-off may affect several floors. Specify the affected unit, affected fixtures and location of accessible valves.
Condos and condominiums
Some work requires access to a common area, a coordinated water shut-off or authorization from the condominium association. Notify the property manager when a shared pipe or several units may be affected.
Rental buildings
Confirm access to the unit, the contact information of the person on site, the history of the problem and previous service calls. This information helps prevent an improperly prepared visit.
Businesses and mixed-use buildings
Access hours, on-site operations, specialized equipment and the impact on neighbouring occupants influence the planning and the team required.
Plumber or 311: who should you call in Montreal?
- Fixture, pipe or private plumbing system: contact a plumbing contractor.
- No water and a pipe that may be frozen on the public side: the City asks residents to contact 311.
- Municipal valve providing access to the water service line: only people authorized by the City may operate it; a request to 311 may be necessary.
- Blocked sewer service line: the City states that the property owner is responsible for its maintenance and clearing up to the connection with the municipal sewer, including beneath public property.
- Suspected structural defect beneath public property: report the situation to 311; the City determines whether the conditions for municipal intervention have been met.
View the official information on plumbing and sewer work in Montreal. The assigned company can diagnose and document the problem, but the City remains the authority for its equipment and authorizations.
The City also states that backwater valves have been mandatory in new Montreal buildings since 2011 and must remain accessible for maintenance. View its advice on backwater valves.
Requests received day and night
When should you call an emergency plumber in Montreal?
A request is urgent when water loss must be stopped, wastewater must be contained, an essential installation must be protected or an immediate danger to the building must be reduced. The company contacted confirms its availability and arrival window before travelling to the property.
Call without delay if you notice:
- an active leak that you cannot isolate;
- a burst, frozen or severely damaged pipe;
- wastewater backing up through a drain, shower or toilet;
- a water heater that is draining or leaking heavily;
- an overflowing toilet with a valve that no longer closes;
- water near an electrical panel, outlet or electrical appliance.
While waiting for service:
- close the fixture valve or indoor main water shut-off if you can do so safely;
- in the event of a backup, stop using toilets, showers, sinks and appliances that discharge water;
- keep people and objects away from the affected area;
- do not touch wet electrical equipment and call emergency services if there is an immediate danger;
- do not open a wall or dismantle a pressurized fitting;
- take photos only when the situation is stable and safe.
A dripping faucet, fixture replacement or renovation project can generally be scheduled during regular business hours.

Pricing to be confirmed
How much does a plumber cost in Montreal?
There is no single price for a plumbing service call. The cost depends on factors including the time of service, travel, minimum charge, access, number of workers, materials and specialized equipment.
Before accepting the service call, ask the company to clarify:
- travel or service-call fees;
- the hourly rate and minimum charge;
- evening, overnight, weekend or statutory-holiday surcharges;
- the cost of specialized equipment and materials;
- what is included in any advertised estimate.
To understand these factors, view the guide to plumbing service costs.
Verification before the work
CMMTQ and RBQ licence: what should you verify?
Ask for the legal name of the company that will contract the work and its licence number. Then verify:
- its membership in the official CMMTQ directory;
- the validity and subclasses of its licence in the RBQ registry;
- the identity of the company listed on the estimate and invoice;
- the scope of work, applicable permits and warranties offered.

Frequently asked questions
FAQ about plumbers in Montreal
What services can a plumber in Montreal handle?
Requests may involve a leak, blocked drain, sewer backup, water heater, plumbing fixture, camera inspection, backwater valve, sump pump, piping or residential and commercial work. SOS Plombiers directs each request based on the area, priority and expertise required.
Are urgent requests received 24/7?
Yes. SOS Plombiers receives urgent requests 24 hours a day, 7 days a week. The company contacted then confirms its actual availability, arrival window and the conditions applicable to the requested time.
How quickly can a plumber arrive in Montreal?
The response time depends on the neighbourhood, traffic, weather, time of day, company availability and required equipment. SOS Plombiers therefore does not promise the same response time for every call. The arrival window is confirmed when a company accepts the request.
How can I know the price before the service call?
Ask the assigned company to confirm the travel fee, hourly rate, minimum charge, time-related surcharges and the cost of any specialized equipment. The final price may require a diagnosis when the cause, access, parts or scope of work are not yet known.
How do I verify the company’s CMMTQ membership and RBQ licence?
Ask for the legal name and licence number of the company performing the work. Then verify its membership in the CMMTQ member directory and the validity and subclasses of its licence in the RBQ public registry.
Does the service cover condos, plexes and rental buildings?
Yes. Specify the type of building, floor, affected units, access to valves and any requirements from the condominium association or property manager. This information helps plan a water shut-off, access to a common area or coordination with other occupants.
When should I call 311 instead of a plumber?
Call a plumber for a fixture, pipe or problem involving the private plumbing system. Call 311 particularly if the water supply appears to be frozen on the public side, if the municipal valve must be operated or if a structural defect is suspected beneath public property. For a blocked sewer service line, the City states that the property owner remains responsible for maintenance and clearing up to the connection with the municipal sewer, even beneath public property.
What should I do while waiting for the plumber during an active leak?
If you can act safely, close the fixture valve or indoor main water shut-off, move exposed objects away and avoid contact with wet electrical equipment. Do not dismantle a pressurized fitting, and contact emergency services if there is an immediate danger to people.
