Which drain is blocked? Reading the signs

The most reliable clue is where the water collects. If only one fixture drains poorly, the clog is almost always close to that fixture. If several fixtures act up at once, or water appears lower in the house, the problem is further down the plumbing.

  • Kitchen sink

    Grease, food scraps and coffee grounds harden in the trap and along the pipe walls. The water drains slower each week, then stops. A stale, greasy smell coming up from the sink is a classic early warning.

  • Bathroom basin, tub and shower

    Here the usual culprits are hair and bar soap, which bind into a tight plug. A gurgling sound as the water goes down means it is struggling for air, often because a partial clog has already settled in.

  • Floor drains and the main line

    A floor drain that lets water rise, especially while the washing machine empties, needs attention right away. The main drain carries everything from the house: when it blocks, wastewater looks for the first way out, which is often the basement. If that is what you are seeing, read our page on sewer backups too.

When should you call a plumber instead of plunging?

A plunger used the right way clears plenty of small sink and basin clogs. As soon as the problem goes beyond one fixture, or refuses to budge, it’s time to call us. In particular when:

  • the water no longer goes down at all, even after several tries with the plunger;
  • more than one fixture drains slowly at the same time;
  • dirty water comes up through a floor drain or the shower;
  • a sewer smell hangs around the house;
  • you already poured in a chemical product and the water is still standing.

Forcing a hardware-store snake into an older line can crack a fitting or push the clog deeper, where it is harder to reach.

How our plumbers clear a drain

Every visit follows the same steps, from your call to the final check.

  1. One call, one price. Someone on the team asks which fixture is affected, since when, and what you have already tried. The price is confirmed before the plumber drives out.
  2. The right tool for your pipe. On site, the plumber checks the trap and the nearest access points first, then picks the method that suits the size and material of the line.
  3. A test on every fixture. Once the water flows again, the plumber runs each affected fixture to make sure everything drains normally.
  4. A clear explanation. You see what caused the blockage and what could bring it back. You pay once the problem is resolved.

How much does drain cleaning cost?

It depends on the fixture, the distance to the blockage and access to the line. A kitchen sink clogged with grease is often cleared from the trap under the sink. A blockage further down the main drain is reached through the cleanout in the basement and takes longer, especially when roots or a sagging pipe are involved. Every clog is different, so we don’t publish a single price: we give you a firm, complete price on the phone before sending a plumber.

  • The price is confirmed before we leave, with no hidden travel fee.
  • No obligation: you accept the price or turn it down.
  • Evenings, weekends and holidays included, the rule stays the same.
  • You pay once the drain is cleared and tested.

Why does a drain keep clogging?

Many duplexes, triplexes and post-war houses around Montreal still have original cast iron or galvanized steel drain lines. Over the years, their inner walls roughen and narrow, so grease and debris catch more easily, and clogs come back sooner after each cleaning. Newer plastic lines are smoother but can sag or separate at a joint if they were poorly supported. Poor slope or tree roots in the main drain can also be to blame.

The plumber tells you plainly what they see and walks you through the options, with no pressure: a more thorough cleaning of the line, a fitting to realign or a section of pipe to replace. That kind of work can be planned when it suits you, and if you are renovating a kitchen or bathroom, it’s the ideal moment to fix a problem drain before the walls are closed up.

A blocked toilet calls for a different approach: read our advice on a clogged toilet before you reach for the plunger. If water is already spreading across the floor, our page on water leaks covers what to do first.

Common questions about blocked drains

(438) 379-2352
How much does it cost to unclog a drain?

It depends on which drain is blocked, how far down the clog sits and how easy the pipe is to reach. On the phone we ask a few questions and give you a firm, complete price before sending anyone, with no hidden travel fee. You decide, with no obligation.

Should I pour a chemical drain opener in while I wait?

Better not. Those products can damage some pipes and seals, they don't dissolve objects or packed debris, and they make the job hazardous for whoever opens the line next. If you already used one, tell the plumber when they arrive.

Why does water come up in the shower when the washing machine drains?

When one fixture pushes water out of another drain, the blockage is usually further along, in a shared line or the main drain. Have the line checked soon, before it turns into a bigger backup.

Is a blocked drain an emergency?

Not always. A slow bathroom basin can wait for an appointment. But if dirty water is coming up through a floor drain, several fixtures are blocked at once or the only toilet in the house won't drain, call right away, day or night.

Do you work for tenants?

Yes. We work for tenants as well as owners. If the building has a property manager, let them know too, especially if we need access to shared areas.

How can I keep my drains from clogging?

Let cooking grease cool and put it in the garbage, add a strainer to shower and tub drains to catch hair, flush nothing but toilet paper, and run hot water through drains you rarely use so their traps don't dry out.
