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.

Start with the symptom
What a plumber in Côte-des-Neiges–Notre-Dame-de-Grâce needs to know first
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.
Describe the pattern
A drain is slow or backing up
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.
Coordinate access
More than one unit is affected
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.
Access and authorization
The right access matters as much as the address
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.
01
Inside your unit
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.
02
In a shared area
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.
03
On a concealed line
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.
Plumbing services
Address the affected point, then investigate the cause
These services cover common needs in the borough. Each has a dedicated page for technical details; the conditions on site determine the work required.
01 · Water
Water leak repair
A fitting, shutoff, fixture, or pipe may be involved. Locate the source and assess the extent of the damage before repairing it.
02 · Drainage
Drain cleaning and unclogging
For a slow fixture, floor drain, or backed-up line, the appropriate method depends on where the problem is found.
03 · Investigation
Drain camera inspection
A recurring blockage or suspected defect in a sewer connection may call for an inspection after the necessary checks and clearing.
04 · Water supply
Water service line and shutoff
A faulty indoor valve or work on the water service line requires a clear distinction between the private piping and a municipal exterior shutoff.
Useful local guidance
When does the City of Montréal need to be involved?
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.
Check the indoor valve and access
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.
Request an exterior shutoff through the borough
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.
Document a suspected sewer connection defect
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.

Common questions
Before requesting plumbing help in CDN–NDG
These answers help you arrange access and understand the possible steps. The assessment on site determines the repair needed.
Can I call an NDG plumber or a Côte-des-Neiges plumber for an urgent problem?
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.
What if the shutoff valve is in a shared room?
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.
Does a sewer backup mean the line under the street is broken?
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.
Does the City have to shut off water to replace a valve?
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.
What affects the cost of a visit?
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.
