Service calls are assigned to CMMTQ-member partner contractors holding an appropriate RBQ licence. Before travelling to the property, the assigned company confirms its availability, arrival window and billing terms.

Plumbing service in Montreal
Provide the address, type of building, affected fixtures and signs you have observed. These details help direct the request to a partner who serves your area and has the appropriate equipment.
For an active leak or sewer backup, calling remains the fastest way to explain the situation.
Emergency, repair and installation
A proper diagnosis begins with the symptoms, not with a solution chosen in advance. The partner checks the cause, access to the pipes and the condition of the system before recommending the work.
Faucet, valve, fitting, visible pipe or water appearing on the ceiling: the priority is to control the water loss, locate its source and determine whether opening a wall or ceiling is truly necessary. See the water leak repair service.
One fixture draining slowly does not point to the same cause as several drains backing up together. Depending on the location of the blockage, the work may require a drain snake, mechanical equipment, pressure cleaning or an inspection of the main drain. See the drain cleaning and sewer backup services.
A camera is most useful when the problem recurs, the pipe is difficult to access, a defect is suspected or the condition of the system must be documented. It may reveal buildup, roots, a collapse or damage without replacing the plumber’s diagnosis. Learn more about camera drain inspections.
Insufficient hot water, a leaking tank, toilet replacement, faucets, sinks, bathtubs, showers or dishwashers: the partner checks the connections, valves, drainage and compatibility with the existing installation. See the page on water heater installation and replacement.
Basement protection depends on the configuration of the system, the level of the fixtures and the source of the risk. A backwater valve, sump pump or drainage correction may be recommended after inspection.
Fixture replacement, piping modifications, renovations, maintenance or work in a commercial property: the request is directed based on the schedule, access and scope of the project. See all plumbing services or the commercial plumbing page.
Choosing the right service
You do not need to know which part is defective before calling. Describe what you see, hear or smell; these details help determine the priority and equipment.
The blockage may be located in the trap or the fixture’s drain line. Specify what has already been tried and whether the water eventually drains.
Gurgling, water backing up or several affected fixtures may direct the inspection toward a stack or the main drain.
Indicate whether the water flows continuously, only while a fixture is being used or after rainfall. The source may be far from the visible mark.
A camera inspection or more thorough cleaning may become appropriate, but only after confirming the access and affected pipe.
Prepare before calling: complete address, building type, floor, affected fixtures, presence of active water, access to valves and photos if the service can be scheduled.
Local realities
In Montréal, the same symptom may require a different approach in a house, plex, condominium or commercial property. Access, shared systems and modifications made over time matter as much as the fixture requiring repair.
A drainage stack, water service line or shared shutoff may affect several floors. Specify the affected unit, fixtures involved and location of accessible valves.
Some work requires access to a common area, a coordinated water shutoff or authorization from the condominium association. The property manager should be notified when several units or a shared pipe may be involved.
The owner, property manager and occupant do not always have the same information. Access to the unit, the history of the problem and previous work must be confirmed before the appointment.
Access hours, on-site operations, specialized equipment and the impact on neighbouring occupants influence scheduling and the type of crew required.
Consult the City’s official information on plumbing and sewer work. The partner can document the problem, but the City remains the authority for the municipal section and authorizations.
To reduce the risk of sewer backups, the City states that backwater valves have been mandatory in new Montréal buildings since 2011 and must remain accessible for maintenance. Consult the City’s guidance on backwater valves.
Day-and-night availability
Urgent service is appropriate when water loss must be stopped, sewage contained, an essential system protected or an immediate risk to the building reduced.
A dripping faucet, fixture replacement or renovation project can generally be scheduled during regular hours.
A clear service process
SOS Plombiers receives and directs the request. The assigned partner company remains responsible for its diagnosis, estimate and completed work.
Provide the address, building type, affected fixtures, how the problem has developed and the level of urgency.
The area, priority and equipment that may be required are used to select a suitable partner contractor.
Before the service call, verify the company name, arrival window, service-call charge, rate, minimum billable amount and applicable surcharges.
On site, the plumber identifies the cause, explains the options and confirms any additional parts or work before proceeding further.
Transparent pricing
There is no single price for a plumbing service call. The cost depends on the timing of the service, travel, minimum billable amount, access, number of workers, materials and required specialized equipment.
Before accepting the service call, request clear confirmation of the following:
To explore these factors without turning this local page into a pricing guide, see our page on plumbing service costs.
Verification before the work
In Quebec, plumbing work entrusted to a contractor must be performed by a company in good standing for the applicable specialty. The fact that a technician arrives does not replace verification of the company contracting for the work.
Request the legal name of the assigned company and its licence number, then verify:

Frequently asked questions
Requests may involve a leak, clogged 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.
Yes. SOS Plombiers receives emergency requests 24 hours a day, 7 days a week. The partner company contacted then confirms its actual availability, arrival window and the terms applicable to the requested time.
Response time depends on the neighbourhood, traffic, weather, time of day, partner availability and equipment required. SOS Plombiers therefore does not promise the same response time for every call. The arrival window is confirmed when the company accepts the request.
Ask the assigned company to confirm the service-call fee, hourly rate, minimum billing requirement, 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.
Ask for the legal name and licence number of the company performing the work. Then verify its membership in the CMMTQ member directory as well as the validity and subclasses of its licence in the public RBQ registry.
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 anticipate a water shutoff, access to a common area or coordination with other occupants.
Call a plumber for a fixture, pipe or problem located on the property. Calling 311 may be appropriate when a municipal component is suspected, the water supply appears frozen on the public side, a shutoff at the municipal valve is required or work must be coordinated with the borough.
If you can do so safely, close the fixture valve or indoor main water shutoff, 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.
