Start with what is happening

Find the right plumbing service

You do not need to diagnose the problem before calling. Start with the situation that best describes your concern; the details help establish the next step.

Urgent problem

Water leaking or sewage backing up?

Call now. For a supply leak, close the affected shut-off valve if it is safe to reach. For a sewer backup, stop using the affected fixtures and keep clear of wastewater.

Call our 24/7 line
Repair & diagnosis

A slow drain, leak or recurring problem?

Describe which fixtures are affected, when the problem started and whether it has happened before. That helps distinguish a local repair from a drainage problem that needs investigation.

Basement protection

Concerned about water in the basement?

A backwater valve and a sump pump address different sources of water. Start by identifying whether water comes through a drain, collects in a sump pit or appears elsewhere.

Explore basement services
Installation & projects

Replacing a fixture or renovating?

A new toilet, an electric hot water tank or a different kitchen layout starts with the existing connections, available access and the scope of the work you want completed.

Browse installation services

No hot water? See electric water heater services. If the tank or its connections are leaking, mention that when you call: an active leak changes the priority.

Our complete service range

Repairs, installations and plumbing projects

Choose a service for a closer look at the problems it addresses, the work involved and the information to prepare for your request.

Plumbing repairs and diagnostics

For visible leaks, clogged drains and problems that return after a previous repair or cleaning.

Leaking pipes & connections

Water leak repair

A dripping connection, leaking pipe or unexplained wet area needs its source assessed. Tell us whether the leak is continuous, occurs only when a fixture runs or appears behind a wall or ceiling.

Explore water leak repair
Slow or blocked drains

Drain unblocking and cleaning

For a clogged sink, toilet, tub or floor drain, and drainage problems affecting several fixtures. The location and extent of the blockage help determine how to restore flow and whether further inspection is needed.

Explore drain cleaning
Inside the drain line

Drain camera inspection

A camera inspection examines the inside of an accessible drain or sewer line. It can help investigate recurring blockages and assess visible pipe conditions before deciding whether cleaning or a repair is appropriate.

Explore drain camera inspection

Basement protection and sewer lines

For wastewater backing up, water collected in a sump pit and underground sewer damage that may require repair.

Sewer backup protection

Backwater valves

A backwater valve helps prevent wastewater from flowing back through the drains it protects. Installation, replacement and maintenance depend on the existing drainage layout, access and the requirements that apply to your building.

Explore backwater valve services
Water in the sump pit

Sump pumps

A sump pump removes water collected in a sump pit. If it does not start, runs continuously or cannot keep up, the pump, pit and discharge arrangement need to be considered together.

Explore sump pump services
Underground drainage

Sewer line excavation and repair

When assessment identifies a damaged underground sewer section, excavation may be needed to reach it. Pipe location, site access, underground utilities and the surrounding surfaces all affect planning for the repair.

Explore sewer line repairs

Hot water, water supply and fixtures

For electric water heaters, the water service line supplying your property and the fixtures you use every day.

Electric hot water tanks

Electric water heaters

No hot water, a leaking tank or a replacement to plan? Share the existing tank's capacity, approximate age and location. Those details help frame the service request and the installation requirements.

Explore electric water heater services
Building water supply

Water service line replacement

The water service line connects the building to the municipal supply. When that line needs replacement, its route, connection points, access and the municipal and private portions must be clarified before work begins.

Explore water service line replacement
Everyday plumbing fixtures

Plumbing fixture installation

For a toilet, faucet, sink, shower or other plumbing fixture. The existing water and drain connections, shut-off valves and available space help determine what is involved in installation or replacement.

Explore plumbing fixture installation

Residential and commercial plumbing projects

For work that involves a new layout, several connections or coordination with occupants, managers and other trades.

Homes, condos & rental properties

Residential plumbing and renovations

Plan the plumbing for a kitchen, bathroom or other residential renovation. Fixture locations, existing pipes, access behind finished surfaces and the timing of other trades all matter when defining the work.

Explore residential plumbing and renovations
Businesses & commercial buildings

Commercial plumbing

Arrange plumbing repairs, installations or renovation work for a commercial property. Operating hours, access restrictions, shared lines and any necessary water interruption should be discussed with the person responsible for the building.

When two services seem similar

The symptom is the starting point

A visible problem does not always reveal its cause. These common distinctions help you describe your request and understand why an inspection or a different type of repair may be needed.

Useful informationTell us what changed, which fixtures are affected and whether the problem has returned.
  1. Drain cleaning or a camera inspection?

    Cleaning addresses an obstruction. A camera inspection examines the accessible pipe interior when the cause, condition or recurrence needs investigation.

  2. Pipe leak or water service line problem?

    A leak at a fixture connection differs from damage to the underground water supply line. The source needs to be established before choosing the repair.

  3. Backwater valve or sump pump?

    The valve helps stop a reverse flow of sewage. A sump pump removes water collected in a pit. One does not perform the other's function.

  4. Fixture replacement or renovation?

    Replacing a fixture in the same position differs from moving pipes or changing a room's layout. Those changes belong in the scope of a plumbing renovation.

Before your call

Four details that help us understand the work

For an urgent problem, call first. For planned work, a few details about your property and the result you want make the discussion more productive.

Keep these details handy

The service address, your contact number, relevant photos and any available fixture model or tank information. You do not need to open walls or dismantle plumbing to prepare.

Immediate concern

What is happening now?

Say whether water is still leaking, sewage is coming back, a valve is closed or several fixtures are unusable. Describe the affected area and whether the situation is getting worse.

Property & access

Where is the plumbing?

Identify the building type and the location of the problem. Mention shared pipes, a locked mechanical room, tenant access or a building manager who needs to coordinate the visit.

History

When did it start?

Explain whether this is the first incident or a recurring issue. Previous repairs, recent renovations and what was happening when the problem appeared can provide useful context.

Planned work

What needs to change?

For an installation or renovation, describe the fixtures, proposed layout and timing. Mention whether products are already purchased and whether walls or floors will be open.

Licence checks & local planning

Official resources for your plumbing project

Check the contractor's licence and the municipal requirements that apply to your address. A fixture replacement, a larger renovation and an excavation can involve different steps. These official resources help you find the relevant information before work begins.

Contractor credentials

Check an RBQ licence

The RBQ explains how to use its licence holder register to check a contractor's identity and licence information. Use our licence number, 5688-9025-01, when searching.

North Shore municipalities

Permits and work declarations

Each municipality provides its own process. Terrebonne explains its permit application steps, while Repentigny distinguishes permit requests from work declarations. Consult the municipality where your property is located.

Before excavation

Locate underground utilities

Info-Excavation explains how to request locations for its members' underground infrastructure before digging. Locating those networks is part of preparing an excavation around a water or sewer line.

Some infrastructure owners are not members and must be contacted separately.

Common questions

Booking plumbing work

What to know when choosing a service, planning a visit or calling about an urgent problem.

24/7 emergency plumbing450-241-0488
Which service should I choose if I do not know the cause?

Start with what you can observe: a leak, a slow drain, a backup, no hot water or a problem affecting several fixtures. Tell us where it happens and whether it has happened before. You can call without choosing a service in advance; those details help determine the appropriate assessment.

Do you offer emergency plumbing 24/7?

Yes. Call 450-241-0488 for emergency plumbing, 24 hours a day, seven days a week. Give the address first, then describe any active leak, sewer backup or unusable fixtures. We will discuss the situation and service availability for your location.

What affects the cost of plumbing work?

The cause of the problem, access to the pipes, required parts and the extent of the work all matter. Emergency timing, excavation or coordination in a shared building can also affect the scope. Ask what the proposed work includes and whether an on-site assessment is needed before a price can be confirmed.

Can you work in an occupied home, condo or business?

Yes. Let us know who occupies the property, who can authorize the work and whether access or a water interruption must be coordinated. In a condo or shared building, include the building manager or syndicate when common pipes or shut-off valves may be involved.

Do I need a permit for plumbing work?

It depends on the work and the municipality or borough. Replacing a fixture and renovating a space that changes walls, layout or connections can involve different requirements. Use the official municipal resources above to check the rules for your address before starting a planned project.
