Get clean water in Montreal, no guesswork
Lavigne Water Systems handles water treatment service across Montreal with expert installation, repair, and maintenance.
Filtration that fits how you use water
We match the right filtration setup for your water, not a one-size-fits-all unit. No guesswork, just clean results.
Whole-home filtration
Every tap gets clean water, from the kitchen sink to the basement shower.
Reverse osmosis systems
Point-of-use systems that remove more contaminants for great-tasting drinking water.
Under-sink filters
Compact units that fit neatly under the sink and deliver better water on demand.
Well water treatment
Iron, sulfur, and sediment filters built for private wells, not municipal water.
System repairs & swaps
Faulty filter housings, worn membranes, and cracked fittings fixed without the runaround.
Maintenance plans
Scheduled filter changes and system checks so you never have to think about it.
Straight answers and clean water, delivered every time
Montreal homeowners and businesses rely on Lavigne Water Systems for honest advice, fair pricing, and water that tastes and tests better.
Samuel tested our water, explained the results in plain language, and installed a filtration system that actually fixed the problem. No upselling, just what we needed.
Marie-Claude B.
Homeowner, Rosemont
Our office water softener kept failing. Lavigne Water Systems swapped it out within a week and walked us through the maintenance schedule. Zero complaints since.
Jonathan R.
Office Manager, Hochelaga
The reverse osmosis system they installed tastes night and day better than what we had. They showed us how to change the filters and left our basement spotless.
Fatima A.
Homeowner, LaSalle
Had a pressure tank issue that another company wanted to replace entirely. Samuel fixed it in one visit and charged a fraction of the quote. That honesty keeps us calling him.
Peter K.
Property Owner, Verdun
For a small café, water quality matters. Lavigne set up our commercial filtration and gave us a simple schedule for the filters. Consistent, reliable, and no surprises on the bill.
Lina M.
Café Owner, Plateau
We bought a house with an old pump and questionable water. Samuel walked us through every option, installed the right system, and made sure we understood how it all worked.
