A pipe or fixture is leaking
Close the accessible fixture shutoff or the indoor main water valve if you can do so safely. Tell us whether the leak continues afterward. Keep clear if water is reaching electrical equipment.
A leak is spreading, a drain is backing up, or a shutoff valve will not close? A plumber in Sainte-Thérèse can inspect the installation and explain the appropriate repair. For emergency plumbing in Sainte-Thérèse, call and describe what the water is doing now. Less urgent work can also be scheduled.

A pressurized leak, wastewater backup, and loss of pressure throughout the building call for different first checks. Describe the symptom before assuming its cause.
If water is still flowing or a drain is backing up, call 514-312-1521 with the address, access details, and affected fixtures.
Close the accessible fixture shutoff or the indoor main water valve if you can do so safely. Tell us whether the leak continues afterward. Keep clear if water is reaching electrical equipment.
Stop using fixtures that discharge into the line and avoid contact with wastewater. Tell us which drain reacted first and whether more than one fixture is affected. Clearing the blockage alone may not resolve a recurring sewer backup.
Check Sainte-Thérèse’s drinking water information (in French). The city notes that flushing its water network can temporarily affect pressure or water colour. If the issue is limited to one fixture, a check of the private plumbing may be appropriate.
The outdoor water service box and an indoor shutoff valve are different access points. If the indoor shutoff does not work, mention it when you call; the next step may require coordination with the city.
We handle common residential plumbing problems, but the approach depends on the affected point, available access, and actual condition of the pipe or fixture. Each service page explains the work in more detail.
A leaking joint, pipe, or valve first calls for isolating the water and checking the extent of the damage. A valve that no longer closes also changes how the repair is prepared.
Drain cleaning depends on the fixture, access point, and extent of the blockage. If the same symptom returns, an inspection of the line can help identify its cause.
A leaking tank, lack of hot water, and a dripping connection require different checks. The location, access, and condition of the unit guide the next step.
An existing backwater valve needs to remain accessible for inspection and maintenance. After a backup, the drainage layout should be understood before choosing a change.
A blockage that keeps returning may call for a camera inspection when the line is accessible and the diagnosis supports it.
A symptom inside the building and work on the public water network do not automatically fall to the same party. The city publishes guidance to help check the situation and prepare certain protective projects.
Locate the building’s main water shutoff and keep it accessible. If an indoor pipe or fixture is involved, tell us where it leaks and which valve is available. For an outdoor service box that needs to be located or repaired, the city provides a request and report service (in French).
Do not manipulate the outdoor box to replace an indoor water shutoff. Explain where the problem lies so the right response can be coordinated.
The city describes an inspection program and a subsidy for certain protection work (in French), subject to specific eligibility criteria. Qualifying work is linked to a municipal inspection and approval before it begins.
If you already have an eligible file, check the recommendations and status of your application with the city. Do not assume that a new valve or pump will be subsidized.
You do not need to identify the failed part. A few observations and clear access help us direct your request, whether it is urgent or planned work in a house, apartment, or condo.
Read reviews displayed by their source to get a sense of communication and service. They may cover different types of work and service areas; they do not all describe visits in Sainte-Thérèse.
The right first step depends on the actual installation. These answers help you prepare the call; an on-site diagnosis determines the work needed.
Yes. Urgent requests are received 24 hours a day, seven days a week. Tell us whether water is still flowing, a drain is backing up, and which shutoffs are accessible. Visit availability and terms are confirmed by phone for your situation.
No. A city notice or water network flushing can also have a temporary effect. Check the city’s water supply information (in French). If a leak is visible, only one fixture is affected, or the problem persists, describe it so the private plumbing can be checked.
No. Camera inspection is most useful when a problem returns, several drains are affected, or a pipe defect is suspected. The access point and condition of the drain must also allow a useful inspection.
No. The municipal program has criteria, an inspection, and an approval process before eligible work. Check your file and current deadlines directly with the City of Sainte-Thérèse (in French) before committing to an expense based on expected financial assistance.
Identify the affected units and who can authorize access to a shared valve or pipe. Clear the area without opening a wall or moving a heavy fixture. If water is actively flowing, mention any access limits when you call.
