The leak is still active
Close the fixture valve if you can do so safely. If water keeps flowing, tell us whether the main shutoff is accessible, whether another unit is affected, and where you see moisture.

Understand the issue first
Need a Saint-Laurent plumber? Start here
Low water supply, an active leak, and a drainage problem call for different first steps. A few simple observations help prioritize the call without taking pipes apart or assuming the source is where the water becomes visible.
If water is near an outlet or electrical equipment, keep clear of the area. You may close an accessible valve without forcing it; if it resists or you are unsure, call us.
Water is off or pressure has changed
Check whether one tap, the whole building, or nearby addresses are affected. Review the City of Montréal’s notices and alerts for a reported interruption. If the issue seems limited to your building, the private water supply may need to be assessed.
A drain is slow or backing up
Stop using fixtures that discharge into the affected line if sewage is coming back up. One clogged fixture and several drains reacting together can point to different areas to inspect.
Work on the right system
Plumbing services for your Saint-Laurent address
This local page helps you direct the request. The service pages explain the methods and decisions in more detail once you know what is affected.
Pipes, fittings, and shutoffs
A damp connection, a valve that will not close, or a leak near the main supply calls for a clear distinction between accessible indoor plumbing and the scope of any work on the service line.
Drains and sewers
A slow kitchen sink may have a different cause from a basement floor drain that backs up. Depending on the history and access, a camera inspection may help after the first checks.
Electric water heater
Water around the tank, lukewarm water, and no hot water call for different checks. The unit’s age, access, and connections help determine whether repair or replacement is appropriate.
Sewer backup and backwater valves
After sewage comes back up, the first task is to understand where it entered and which fixtures are affected. An existing valve still needs to be accessible and checked for its condition.
What the address tells us
Saint-Laurent has more than one type of building.
Bois-Franc and Nouveau Saint-LaurentHouses, townhouses, and condominiums depending on the address.Village MontpellierCondominium buildings are part of this area.Vieux-Saint-LaurentA neighbourhood centre with homes and businesses.
Useful context, no assumptions
Access and authorization shape the visit
The City’s official Saint-Laurent profile describes several residential areas and building types. That cannot tell anyone the condition of the pipes at your property. Your building’s layout, however, helps prepare a service call.
For a house, tell us where the main shutoff, water heater, and affected drain can be accessed. For a condominium or multi-unit building, identify the unit, access to shared areas, and the person who can authorize entry to a mechanical room or a building-wide water shutoff.
A photo of a visible fitting or drain can help describe the problem when the area is stable and safe. It does not replace an on-site assessment.
The problem is in private plumbing
A leaking fixture, water heater, indoor valve, or building drain needs a plumbing assessment first. Describe the symptoms, access, and any work already attempted. The appropriate repair can be determined after inspection.
The exterior shutoff is needed
If work requires the water service to be shut off outside, the request goes through the borough. The City explains how to request a shutoff or locate the service box. Select Saint-Laurent and check the applicable steps before scheduling work.
From the call to a decision
A visit prepared around your problem
One symptom can have more than one cause. The goal is to define what needs to be checked and then explain the options based on the condition of the plumbing and the access available.
STEP 01
Describe
Address, building type, affected fixture, active or occasional symptoms, when the issue began, and access to the shutoff or mechanical room.
STEP 02
Check
Identify the part of the system involved, the available access, and the scope of the visit. A camera inspection or municipal coordination is considered when the findings call for it.
STEP 03
Choose the next step
Depending on the cause and required parts, the answer may be a targeted repair, replacement, or work to schedule. The scope is explained before work begins.

Useful questions
Before requesting service
These answers help you describe the issue. An on-site assessment is still needed to confirm the cause and the scope of work.
There is no water. Should I call the City or a plumber?
If several addresses seem affected, start with Montréal’s notices and alerts. If the problem appears limited to your building, note which taps still work, the position of the indoor shutoff, and any notice received for your street. A plumber can assess the private system; the City handles its own infrastructure.
Does every leak require the exterior service box to be shut off?
No. A fixture valve or the indoor main shutoff may isolate some work. If an exterior shutoff is needed, the borough explains how to request it. Do not force a faulty valve; tell us what can be closed safely.
Does a clogged drain always need a camera inspection?
Not always. A camera may be useful when a blockage returns, several drains react together, or the cause remains uncertain after the first checks. The decision depends on the line and access.
What should I prepare for a condo or rental unit in Saint-Laurent?
Share the unit and floor number, affected fixtures, and access rules. If a valve or pipe serves several units, contact the building manager or condo syndicate to clarify authorization and coordination.
Does a sewer backup after heavy rain mean the street is at fault?
Not necessarily. The water’s entry point, path, and the building’s protection need to be examined. The City describes stormwater measures in Saint-Laurent, but those measures do not diagnose a particular property. Stop using fixtures that discharge water if sewage is backing up.
