Plumber in Senneville | 24/7 Service | Plomberie A+
Senneville is like nowhere else on the island of Montreal. Tucked away at the western tip of the West Island, this village of barely 900 residents keeps a rural, wooded character you simply will not find in the busier suburbs nearby. Grand heritage estates stretch across large, tree-covered lots down to the shore of the Lake of Two Mountains (Lac des Deux Montagnes), a short distance from the Morgan Arboretum and the surrounding nature reserve. The village core, recognized as a National Historic Site, holds dozens of homes built between 1860 and 1930 by the leading business families of the era — founders and directors of the Bank of Montreal and the Canadian Pacific Railway. Caring for the plumbing in properties like these takes real experience and a careful hand. At Plomberie A+, a licensed RBQ plumber, we serve Senneville around the clock, day and night.
Homes in Senneville are anything but standard. The large, century-old estates hide extensive plumbing systems: long pipe runs, multiple bathrooms, service kitchens, outbuildings, and sometimes an older private well or water-supply system. In these pre-war buildings we regularly find cast iron, corroded galvanized pipe, and old water service lines nearing the end of their life. Add to that the waterfront and low-lying lots along the Lake of Two Mountains, which are more exposed to seepage and sewer backups during the spring melt and heavy rain. On a property of this value, a small ignored leak can cause serious damage — so our first move is always to get the diagnosis right before we touch anything.
Our plumbing services in Senneville
24/7 emergency plumbing
A pipe that bursts in the middle of winter, a water heater emptying into the basement, or a sewer backup on a Sunday night will not wait — least of all in a large home set back from the road. We answer emergency calls throughout Senneville, around the clock. See our 24/7 emergency plumber service for a fast response.
Backwater valves and flood protection
Waterfront properties and low-lying lots near the Lake of Two Mountains are especially vulnerable to sewer backups during heavy rain and the spring thaw. A properly installed backwater valve on the sewer connection stops wastewater from rising into the basement, and a sump pump handles the most exposed lots. We assess your situation, keep you dry, and make sure the work meets the municipal sewer-connection bylaw.
Drain cleaning and camera inspection
Senneville’s large, wooded lots — full of mature maples and pines — invite tree roots into sewer laterals, which are often very long on these sprawling properties. Before assuming the worst, we run a camera down the line. Explore our drain cleaning and camera inspection services to see exactly what is blocking the flow.
Old pipe replacement
In the village’s heritage homes, we replace cracked cast iron, clogged galvanized pipe, and old water service lines. We work carefully to protect the original finishes, woodwork, and character of these historic residences — with no unnecessary demolition.
Water heater installation and replacement
Large homes with several bathrooms put heavy demand on the water heater — sometimes two of them. We advise on the right capacity and take care of the water heater installation properly, before it fails.

Frequently asked questions — Plumbing in Senneville
My estate is right on the Lake of Two Mountains. How do I protect my basement from flooding?
On a waterfront or low-lying lot, the winning combination is a working backwater valve on the sewer connection and, in many cases, a sump pump. We inspect your current setup, identify where water is getting in, and recommend the protection that fits your property.
My heritage home is over a hundred years old. Do I need to redo all the plumbing?
Not necessarily. Many older Senneville homes still have cast iron, galvanized pipe, or old water service lines, but not all of it needs replacing. A camera inspection and a pressure test tell us exactly what has to be redone — without tearing out irreplaceable original finishes.
My lot is large and wooded. Is that a risk to my drains?
Yes. On Senneville’s big lots, sewer laterals run long and often pass through areas planted with mature trees. Roots seek out moisture and work into the joints. A camera inspection quickly confirms whether there is intrusion, so we can recommend the right fix before a full blockage.
