Water is still flowing
If a leak is active, keep away from wet areas near electrical equipment. Close only the accessible valve for the affected area if you can do so safely, then call.
Need a plumber in Côte-des-Neiges–Notre-Dame-de-Grâce for a leak, a backed-up drain, or work you are planning? Tell us what is happening and where the affected connection can be accessed. We can help plan the next step whether the problem is in one unit or a shared building system.

The same water stain could come from a visible fitting, a fixture, or a pipe crossing several units. A few useful observations help us prepare for the visit without pretending to diagnose the cause over the phone.

One slow sink and several gurgling fixtures call for different checks. Note which fixtures are affected, when the problem began, and whether there is a backup on a lower level.
In a duplex, condo, or rental building, access to a stack, basement, or shared shutoff may require help from the owner or building manager.
If wastewater is backing up, stop using the connected fixtures and avoid direct contact. The blockage must be located before choosing a cleaning or repair method.
From Côte-des-Neiges to NDG, a request may involve a house, a rented apartment, a condo, or a commercial building. A valve or pipe accessible inside your unit may be inaccessible elsewhere in the property.
For broader coverage, see our Montreal plumber page.
Give us the unit number, floor, and fixture involved. Clear access to the sink, toilet, or water heater if you can do so without moving anything unsafe.
Tell us who can open the mechanical room, garage, or basement and who must authorize a water shutoff affecting other occupants. Isolating a shared line may need to be coordinated in advance.
A ceiling stain or a drain problem in several units does not always reveal the source. We review the access and symptoms before recommending an opening in the finish or a pipe inspection.
These services cover common needs in the borough. Each has a dedicated page for technical details; the conditions on site determine the work required.
A fitting, shutoff, fixture, or pipe may be involved. Locate the source and assess the extent of the damage before repairing it.
For a slow fixture, floor drain, or backed-up line, the appropriate method depends on where the problem is found.
A recurring blockage or suspected defect in a sewer connection may call for an inspection after the necessary checks and clearing.
A faulty indoor valve or work on the water service line requires a clear distinction between the private piping and a municipal exterior shutoff.
An indoor repair, an exterior water shutoff, and a request concerning a sewer connection beneath the street follow different processes. The assessment and proposed scope of work determine which one applies.
Do not operate the exterior service box yourself to replace an indoor shutoff valve.
If the issue is inside the building, tell us where the accessible valve is and whether it works. Mention an active leak before that valve when you call so the next steps can be coordinated.
To close or locate the valve between the building and the municipal water main, the owner or their representative must contact the borough. Montréal’s water service shutoff procedure explains the process; call 311 to confirm the steps for your address and situation.
If an inspection points to a structural problem beneath public property, the City explains the sewer connection repair request and its supporting documents. A backup alone does not establish that the portion under the street is broken.
A clear description helps distinguish a repair in one unit from a shared-building problem. Tell us what you know; we can identify what still needs to be checked.
These are published Google reviews from Plomberie Anjou customers across different services and areas. We do not present them as though every review came from Côte-des-Neiges–Notre-Dame-de-Grâce. The widgets display the rating and review count supplied by their source.
These answers help you arrange access and understand the possible steps. The assessment on site determines the repair needed.
Yes. Urgent requests are received 24 hours a day, seven days a week. Tell us if water is still flowing, a drain is backing up, or an essential fixture cannot be used. Availability and the visit time are confirmed for the address and situation.
Contact the owner, condo board, or building manager for the necessary access and authorization. Do not cut off water to several units without coordination. If water is actively flowing and access is unavailable, mention that when you call.
No. A backup can have several causes and possible locations. The line’s condition must be established and, where appropriate, inspected before concluding that there is a structural break and preparing a municipal request.
Not always. It depends on the valve and whether water can be isolated inside the building. If an exterior shutoff is necessary, the owner or their representative must follow the borough’s process and coordinate the on-site visit with the plumber.
Urgency, access, investigation time, parts, and equipment affect the scope of work. Describe the issue and ask about the applicable terms before authorizing the work. One fixed price would not fit every situation.
The exact address helps confirm coverage and access. See our pages for these other areas.
Leak, drain, valve, or planned work: share the address, access details, and symptoms. We will confirm how to proceed for your request.
