Unclogging pipes: Our expertise
At Plomberie CSM, we specialize in unclogging residential and commercial pipes on the South Shore of Montreal. Whether it's a backed-up toilet, a slow-draining sink, or a completely blocked floor drain, our team responds quickly with the right tools to solve the problem at the source.
What should be unclogged?
A clogged pipe can quickly cause significant inconvenience: water backup, bad odors, water damage or interruption of your business activities.
We operate 7 days a week, using professional equipment adapted to all types of blockages. We unblock:
- Toilets, sinks, bathtubs and showers.
- Floor drains and traps.
- Kitchen pipes (grease, soap, food residue).
- Main and secondary pipes.
- Drop columns in apartment buildings.
- Commercial and industrial drains.

Our unblocking techniques
Our qualified plumbers first assess the situation, then choose the most effective method depending on the severity of the blockage:
- Mechanical Cable (Drain Snake): Ideal for localized blockages and small conduits.
- High-pressure jet (hydrojet): Perfect for grease, limescale or debris buildup in main lines.
- Camera inspection: To precisely locate the origin of the blockage and detect anomalies (breakage, roots, subsidence).
