Water leak repair
A dripping connection, water under a sink or a damp patch that returns: note whether the leak is constant or appears only when a fixture runs. The first step in a repair is finding the source.
Looking for a plumber in Boisbriand for an emergency or planned work? Plomberie Anjou handles water leaks, drain cleaning, electric water heaters and plumbing fixtures. Tell us what is happening so we can discuss the next step.

A continuing leak, water coming up in the basement or a leaking water heater calls for prompt attention. Tell us where the water appears, whether it is rising and which fixtures are affected.
For a supply-line leak, close the indoor shutoff valve you know, provided you can reach it safely. If you are unsure which valve to use, say so when you call.
If wastewater is backing up, stop using toilets, taps and appliances that discharge water. Keep children and pets away from the affected area.
Do not enter a flooded area where electrical equipment may be affected. Take photos only from a dry place and only if you can do so safely.
Water near electrical equipment needs special care. Read Hydro-Québec’s flood and electrical safety guidance. Do not dismantle a pressurized pipe or open a sewer cleanout to try to handle an emergency yourself.
One slow fixture and several affected drains may call for different checks. These details help you describe the problem and find the relevant service.
A dripping connection, water under a sink or a damp patch that returns: note whether the leak is constant or appears only when a fixture runs. The first step in a repair is finding the source.
For drain cleaning, tell us which fixture is affected and what happens elsewhere in the home. A shower that gurgles when the toilet flushes is useful information, though it does not establish the cause by itself.
If wastewater returns through a drain, stop sending more water into the system and report the backup. The entry point, affected fixtures and timing help guide the investigation.
A puddle at the tank, loss of hot water or a planned replacement calls for a look at the unit and its connections. Share the model and location if you can check them safely.
Before calling, check whether the drain looks dry, drains normally or has water coming back up. These signs help distinguish an odour alone from a drainage problem.
The City covers these situations in its sewer and floor-drain guidance (in French).
An infrequently used floor drain can lose the water in its trap. For an odour, the City advises adding water to the floor drain. If it backs up or does not drain, stop adding water.
If the smell persists after the trap holds water again, other checks are needed. Avoid masking the issue with drain chemicals.
Say whether it happens after you use a fixture or during rain, and whether another drain reacts too. Report a sewer backup to the City as well so it can help locate the source.
Keep access to the sewer cleanout clear. Do not remove its cap yourself when the line may be under pressure.
For a faucet, toilet, sink or other residential plumbing work, a clear description helps prepare the visit. Mention what you want replaced, any parts already purchased and any limits on access.
In a condo or multi-unit building, alert the responsible person if the work affects a shared supply or requires entry to another unit. Coordinate a shared water shutoff in advance with the occupants involved.
Public Works operates the outdoor service shutoff, locally called the bonhomme à eau. Contact the City’s citizen service centre before work that requires this shutoff. Someone must be inside the home when the water is turned back on to check for leaks.
Report a sewer backup to the City as well as requesting help with the affected plumbing. Its official contact page identifies whom to reach for a municipal emergency outside office hours.
Read customer reviews and tell us what you need when you get in touch: the problem, access to the plumbing and the work you have in mind.

Not necessarily. A dry trap, a gap that lets odours escape and a drainage problem can show different signs. Tell us if the smell comes with gurgling, slow drainage or water backing up. Those details help direct the checks.
Describe which fixtures are affected and what happens when you use water. If water comes back up, stop using the fixtures and call. Several affected fixtures may point to a shared line rather than a single trap.
Yes, but share the model and photos of the current installation first. Dimensions, connections and access must suit the new fixture. Keep the purchased parts, instructions and packaging on hand so the contents can be checked.
Check with the condo association or property manager whether the installation belongs to your unit or a common area. Confirm who can approve the work, the access rules and any shared water shutoff before booking.
The problem, access, condition of the installation, parts needed and scope of work all affect cost. Photos and a clear description help frame the request, although some checks require a site visit. Ask what is included and have any additional work confirmed before it proceeds.
