The problem first, the tool second
When should you call a plumber in Saint-Laurent?
The same water mark can come from an exposed fitting, an appliance or a concealed pipe. A precise description keeps each call from turning into guesswork.
Water keeps flowing or reaching another room
Identify the apparent source, flow rate, accessible valve and any proximity to electricity. An active leak, sewer backup or draining water heater calls for a direct phone call.
A fixture is malfunctioning without active damage
Dripping faucet, unstable toilet, irregular pressure or slow drain: note what triggers the problem and when it began.
You are replacing equipment or renovating a room
For a water heater, sink, toilet or bathroom, prepare dimensions, photos, timing and access constraints.
The problem returns after an earlier intervention
Gather invoices, observations and the times when the symptom returns. A more targeted inspection may be proposed based on the history and access.
Availability and the arrival window are confirmed after checking the address, active situation and required equipment.
Before the visit
Limit damage without taking unnecessary risks
The right steps depend on the problem, but safety always comes first.
- 1Close only a safe, clearly identified valve
Do not enter a wet area near an electrical source.
- 2Stop using the affected fixtures
For a sewer backup, avoid sending more wastewater into the system.
- 3Keep access points clear
Prepare access to the affected sink, bathroom, water heater, basement or mechanical room.

Several generations of housing
Plumbing is not configured the same way throughout Saint-Laurent
Different parts of the borough were developed at different times. Access, previous renovations and shared pipes often matter more than the visible age of the finishes.
Norvick and Marlborough
In these residential areas dating from the 1940s and 1950s, a house may have undergone several renovations. Locate the water service entry, water heater, valves and basement access before calling.
Chameran, Norgate and the Côte-Vertu corridors
For a rental building, provide the unit, floor, affected neighbours and the person responsible for common areas. A shared water shutdown must be coordinated.
Village Montpellier
Large condominium buildings often require authorized access to risers, valves or mechanical rooms. Identify the syndicate or property manager to contact.
Bois-Franc and Nouveau Saint-Laurent
Condos, townhouses and detached homes may have newer systems, without being immune to fixture leaks, clogged drains or plumbing changes during a renovation.

Private property and municipal work
Know who to call based on where the problem is located
The plumber assesses accessible installations on the property. Some operations on public property or the exterior valve, however, fall under the City’s responsibility.
Private installation
Leak, fixture, water heater, drain, backwater valve, interior piping or private service line: the plumber determines what is accessible and explains the proposed scope.
Municipal valve and public property
Closing an exterior valve, working beneath the street or obtaining certain authorizations must follow the municipal procedure that applies to the address.
Protecting basement fixtures
If the building has fixtures below ground level, accessible and maintained backwater valves remain important. The City explains measures that help prevent sewer backups.

House, condo, multiplex or rental building: provide the unit, floor and any other occupants affected.
Prepare access
