Drain, sink and toilet unclogging

A drain does not block all at once. It slows for weeks, gurgles, gives off a smell, then finally backs up — usually at the worst moment. The blockage formed long before you noticed it.

Clearing a drain is one thing; understanding why it blocked is another. A kitchen sink that clogs every year and a main drain that backs up after heavy rain are telling you two different things.

Drain unclogging is part of the 24/7 service offered by Plomberie Boucherville.

Does this sound familiar?

  • Water drains slowly in the sink or tub
  • The toilet empties poorly or rises
  • Gurgling can be heard from another drain
  • A sewer smell comes from the drains
  • Water rises in the basement floor drain
  • Several drains block at the same time

How we work

  1. Locate the real blockage

    A single blocked drain is local. Several blocking at once means the main drain — and the two are not handled the same way.

  2. Mechanical clearing

    The blockage is removed mechanically. Over-the-counter chemical drain cleaners are avoided: they attack older piping and hide the cause instead of fixing it.

  3. Verify the flow

    We run water to confirm the flow is back to normal and explain what caused the blockage.

Frequently asked questions

Why does my drain keep blocking in the same place?
A blockage that returns to the same spot almost always points to a physical problem: insufficient slope, a shifted joint, a root that has entered the pipe, or grease building up on a rough section. Clearing it fixes the symptom for a few months; the defect has to be identified to fix the cause.
Can I use a chemical drain cleaner?
It is not recommended. These products give off heat and can deform PVC or accelerate corrosion in the old cast-iron piping common in homes built before the 1980s. If they fail to clear the blockage, the product sits stagnant in the pipe and becomes a hazard for whoever opens the drain next.
What most often blocks a kitchen drain?
Grease. It goes down as a liquid in hot water, then hardens as it cools on the pipe walls and traps everything that passes afterward. That is why cooking oils belong in the garbage, never in the drain.
