Plumber in Dorval | 24/7 Service | Plomberie A+
Dorval has a story few West Island towns share. Once a lakeside resort and farming community on the shores of Lac Saint-Louis, it suburbanized almost all at once during the 1950s and 1960s. When Highway 20 was widened and the Dorval Gardens shopping centre opened in 1954, thousands of families moved in to brand-new bungalows and split-levels. The result today: a large share of the housing stock is 60 to 75 years old, and the original plumbing is reaching the end of its service life across whole neighbourhoods at roughly the same time. At Plomberie A+, a licensed RBQ plumber, we know this Dorval reality well and we serve the entire area, 24/7.
In sectors like Strathmore, Surrey and the Dorval Gardens area, we regularly find corroded galvanized supply lines and cast-iron drain stacks that have outlived their normal lifespan. Closer to the water, along Du Bord-du-Lac-Lakeshore Road and through the Pine Beach sector, low-lying lots and a high water table bring their own challenges. And north of Highway 20, right next to Montréal-Trudeau airport (YUL), the mix of homes and businesses calls for a plumber equally comfortable in a bungalow basement and a commercial unit. Our job is to get the diagnosis right before we touch anything.
Our plumbing services in Dorval
24/7 emergency plumbing
A water heater letting go in the basement, a galvanized pipe failing inside a wall, a sewer backup on a stormy night — none of it waits until morning. We answer emergency calls across Dorval, from Strathmore to the lakeshore, around the clock. See our emergency plumber service for a fast response.
Galvanized supply and cast-iron drain replacement
This is the heart of our work in Dorval. Post-war homes were almost all plumbed with galvanized steel for supply and cast iron for drainage. After six or seven decades, the galvanized clogs from the inside and the cast iron cracks. We replace those sections with modern materials, cleanly, keeping damage to finishes to a minimum. When needed, we confirm the exact condition of the lines with a camera inspection before we dig or open a wall.
Drain cleaning and tree roots
Dorval’s mature streets are lined with trees planted during that first wave of construction. Over the years, roots seek out moisture and work their way into the joints of old sewer laterals. Our drain cleaning service clears the blockage, and the camera tells us whether a more permanent repair is needed.
Backwater valves and sump pumps near the lake
Low-lying properties near Lac Saint-Louis — particularly in Pine Beach and along Bord-du-Lac — live with a high water table and spring high water on the lake. Even without the severe flooding some other riverside areas have seen, it pays to be protected. We install and maintain backwater valves and sump pumps to keep those basements dry.
Water heater installation and replacement
In homes this age, the water heater has often already been replaced once or twice — but rarely before it starts to leak. We advise on the right model and handle the water heater installation properly, before the failure rather than after the water damage.

Frequently asked questions — Plumbing in Dorval
My Dorval home dates from the 1950s. Do I need to replace all of my plumbing?
Not necessarily all at once. Many homes from that era have already had part of their plumbing replaced. An inspection and a pressure test tell us whether your galvanized supply is clogging or your cast-iron drains are cracking, and we target the sections that need redoing instead of tearing everything out.
I live near Bord-du-Lac and my basement gets damp every spring. What can I do?
Close to Lac Saint-Louis, the water table rises with the snowmelt. We first figure out where the water is coming from — seepage, foundation drain, or backup — then recommend the right protection: a sump pump, a backwater valve, or both depending on your lot.
My water runs slowly and sometimes tastes metallic. Is it my pipes?
Very likely. In Dorval’s post-war homes, galvanized pipe corrodes from the inside: the diameter narrows, pressure drops, and rust mixes into the water. That is the classic sign it is time to replace that section of supply line.

« I was lucky to have Adam come and fix our issue. From the first meeting I knew he was different from other plumbers. He spent close to an hour even before providing an estimate to really make sure he was able to diagnose the problem. We dealt with other plumbers that just couldn’t get the job done… »
