Plumbing services in Laval
From diagnosis to repair.
Every plumbing problem has its own cause. Choose the service that matches the symptoms, or contact us if you are unsure where to begin.
Drain unclogging and cleaning
Slow drain, blocked toilet, persistent odour or sewer backup: restore the flow and identify what caused the blockage.
Water leak repair
A pipe, fitting, faucet or fixture that is allowing water to escape.
Drain camera inspection
Locate a blockage, roots, damage or a collapsed section before planning the work.
Water heaters
Installation, replacement or troubleshooting for a tank that leaks or no longer heats properly.
Backwater valves and sump pumps
Equipment that should be inspected, maintained or replaced to help manage sewer-backup and water-accumulation risks.
Major plumbing work
Is the problem under the slab or beneath the property?
Recurring blockages or a damaged pipe can require a larger repair. An inspection helps locate the affected section before excavation begins.
Local plumbing service
A plumber in Laval—and the right call when the City must intervene.

A plumber, the City—or both?
Three common situations in Laval.
These guidelines do not replace a professional diagnosis. They help you avoid losing time when water is rising or a service connection needs repair.
The problem affects one property
A sink, toilet, water heater or several drains in the same building are affected: stop or limit water use and call a plumber to locate the cause.
The municipal network may be involved
Water is appearing in the street, a street catch basin is overflowing or neighbouring properties are affected simultaneously: contact 311 and protect the building.
Sewage is backing up into the basement
Stop using water. A plumber can inspect the drains and backwater valves; notify the City as well if the public network may be involved.
Laval conditions
What to monitor by season and building type.
Prepare the basement before water rises
The City monitors waterways surrounding Île Jésus and publishes guidance for exposed sectors. Before the spring thaw or a major storm, test the sump pump and make sure protective devices remain accessible.
Laval flood guidance ↗A backwater valve must remain accessible and maintained
Municipal documentation addresses valves on basement drainage connections and does not permit a valve on the building’s main collector. The proper configuration depends on the existing plumbing.
Laval wastewater information ↗Identify the pipe before deciding what to replace
If the material of the water service line is unknown or lead is a concern, the City provides drinking-water information. An inspection helps distinguish fixtures, indoor piping and the service connection.
