Leak or faulty fixture
Identify the affected fixture and, if possible, isolate it using its indoor valve. A leaking connection, toilet or electric hot water tank needs an assessment based on the condition of the installation and access to it.
Laval · 24/7 emergencies and planned work
A water leak, a drain backing up, or a hot water tank that needs replacement? Tell us what is happening, where you are in Laval and what kind of building is involved. Plomberie Anjou will discuss the next step for an urgent problem or a scheduled job.

The right contact depends on the source
A leaking connection, a basement floor drain backup and an outdoor water shut-off call for different steps. These clues help direct the call without assuming what caused the problem.
Identify the affected fixture and, if possible, isolate it using its indoor valve. A leaking connection, toilet or electric hot water tank needs an assessment based on the condition of the installation and access to it.
If several fixtures are affected or the floor drain backs up, stop using water. The City of Laval advises calling a plumber who holds an RBQ licence and belongs to the CMMTQ first to determine the source. If the assessment shows that the City needs to act, then contact 311.
When work requires the outdoor service valve to be operated, only a City employee may handle it. Arrange the request through 311. Laval also distinguishes the private portion of the service connection, for which the property owner is responsible.
Plumbing services
Describe the issue or project when you call. These services cover diagnosis, repairs, prevention, and residential or commercial plumbing work.
An active leak, a frozen or burst pipe, and a water service line issue call for different checks. Tell us where the problem appears and whether the indoor shut-off valve is accessible.
A slow drain or recurring blockage may call for unclogging, camera inspection or hydro jetting depending on the line's condition and the cause found.
If wastewater backs up or a sewer line is damaged, diagnosis helps identify the affected section. Excavation is planned only when the assessment supports that approach.
A backwater valve and a sump pump have different jobs. Their condition, accessibility and the drain layout determine what maintenance or correction may be appropriate.
A leaking tank, reduced hot water or a fixture that needs replacement should be considered in light of the model, connections and available space. Photos and measurements can help prepare a planned installation.
For a new installation, a bathroom or kitchen renovation, or work in a commercial space, tell us the building type, affected fixtures and desired timing.

Planning a larger job
In Laval, work affecting water or sewer service connections, drainage or stormwater management on private property requires a connection permit. The scope, access and any coordination with the City should be clarified before scheduling the work.
For a routine indoor repair, describe the fixture and the symptom. If the job requires a shared water shut-off in a multi-unit building, notify the person who manages access.
Customer reviews
Each review describes a different job. The diagnosis and availability for your request will be confirmed when we speak.
Common questions
For an active leak or sewage backing up, call directly instead of waiting for a response to the contact form.
Yes. Emergency calls are accepted 24 hours a day, 7 days a week. Explain the issue and address at 514 312-1521; availability and the next step are confirmed by phone.
No. The first assessment considers the symptoms and affected fixtures. A camera inspection can help when the blockage recurs, the cause remains unclear or a line needs examination before repair.
The outdoor service valve is handled through the City: only a Laval employee is authorized to operate it. Contact 311 to arrange a shut-off needed for the work, and tell us what needs repair indoors or on the private service connection.
The cost depends on the problem, access, time of service, parts and the work identified after inspection. Describe the symptoms and building type so the applicable terms can be discussed before the visit.
