Plumber in Pierrefonds | 24/7 Emergency Service | Plomberie A+ | (514) 242-9691

Pierrefonds-Roxboro isn’t your typical West Island neighbourhood. It’s a riverside suburb stretched along the Rivière des Prairies, and that closeness to the water shapes plumbing here more than anywhere else on the island. Farmland until the early 1950s, the area boomed in the 1960s when its population tripled almost overnight, filling out with bungalows and detached single-family homes. Six decades on, many of those houses along Gouin Boulevard, Pierrefonds Boulevard and the older streets in the Des-Rivieres and Noel sectors still run on aging cast-iron and galvanized steel piping. More importantly, Pierrefonds was one of the hardest-hit areas in the historic 2017 and 2019 spring floods, the worst the borough had seen since 1974. At Plomberie A+, we know this ground, and we approach every call here with the river in mind.

Our plumbing services in Pierrefonds

Flood protection and sewer backup prevention

This is the core of our work in Pierrefonds-Roxboro. When the Rivière des Prairies rises in spring, water pushes back up through basement floor drains, especially in the low-lying streets near the shore such as Dauville, Chateau-Pierrefonds and 5th Avenue North in Roxboro. We install and maintain complete protection systems tailored to your home: a real basement assessment, plain-language recommendations, and work that meets municipal standards.

Backwater valves

Since 2011, a backwater valve has been mandatory in all new buildings in Montreal, and it becomes required the moment a property has experienced a backup. It’s also the first thing insurers ask for after a flood. We install the right valve on the right collector, service it twice a year, and walk you through how it works so a heavy rainfall never catches you off guard again.

Sump pumps and French drains

In an area with a high water table and plenty of spring melt, a reliable sump pump is essential. We install and replace pumps, check foundation drains, and point you toward the City’s subsidy programs (up to $1,500 for certain pumping and retention-tank systems).

Replacing aging piping

Pierrefonds homes from the 1960s and 1970s often hide cracked cast-iron drain stacks and corroded galvanized supply lines that choke your water pressure. We replace those sections without tearing the whole house apart, and we use camera inspection to see the true condition of your pipes before anyone digs.

Drain cleaning and 24/7 emergencies

Blocked basement drain, water damage in the middle of the night, a leaking water heater? Our 24/7 emergency service covers all of Pierrefonds-Roxboro, and our drain cleaning crew shows up with the equipment to fix it the first time.

Frequently asked questions

My home near the Rivière des Prairies has flooded before. Where do I start?
We start with a basement inspection to find the water entry points, then prioritize: backwater valve, sump pump, and a check on the French drain. Those three are the foundation of real protection in the low-lying parts of Pierrefonds.

Is a backwater valve really mandatory?
For new construction in Montreal, yes, since 2011. And if your property has already had a sewer backup, installing one becomes required, and your insurer will likely ask for it too. We fit the model that suits your situation.

My pipes date from the 1970s. Do I have to replace everything?
Not necessarily. A camera inspection lets us see the real condition of your lines and replace only the problem sections. Many Pierrefonds homes need nothing more than targeted repairs.
