Clogged drain, sewer backup or basement flooding? The most important thing is to act fast. If water has nowhere to go and you keep using it, it will keep backing up, eventually overflowing and flooding the area.
Flooding after a blocked drain
Montreal has a combined sewer system in many neighbourhoods. During heavy rain, the system can overload and water may come back up through your sewer line, a sump pit that can no longer keep up, or the lowest point such as a shower drain or floor drain. The first step is to identify whether it is a blockage in your building, a municipal backup or a drainage-capacity issue, because the solution is not the same.
Sewer backup in the basement
Black water coming up through the floor drain or basement toilet is the most urgent scenario. A municipal sewer backup can push wastewater back toward your building through the sewer line. That water contains bacteria. Montréal guidance calls for backwater valves on basement fixtures in some situations, such as after a backup, flood or renovation — check with the city or a licensed professional to confirm what applies to your building.
Main drain completely blocked
A completely blocked main drain can stop water from draining properly and cause a backup through the lowest fixtures. Roots, wipes and buildup can contribute to the blockage. A camera inspection may be recommended if the problem keeps coming back.
Most emergencies start with signs we ignore. A slowly flushing toilet, a sink that drains slower and slower, gurgling noises — if you had noticed them earlier, we wouldn't be here now. Preventive maintenance can help you avoid a 2 a.m. emergency. But if you do need us at night or on a weekend, we don't add an after-hours surcharge.

Our Emergency Response Process
Here is how the emergency call works, from the first phone answer to the final drainage test.
1. We answer and ask what is happening
We ask where the water is backing up, which fixtures are affected, and whether the problem sounds local or tied to the main drain.
2. We check access and confirm the problem
On site, we confirm what was discussed by phone, check available access points, and identify the likely source of the blockage or backup.
3. We clear the blockage
We clear the drain blockage using the access point that makes sense for the situation, without making tools the main selling point.
4. We test the drainage before leaving
We run water, check that drainage is moving properly again, and make sure the backup has stopped before we leave.
What to Do While You Wait for Us
While we are on the way:
- Shut off the water supply if a toilet or sink is overflowing.
- Do not pour any chemical down the drain.
- Move what you can off the basement floor.
- Take a photo of the situation for us.
Pricing for Emergency Drain Unclogging
Clear pricing before the work starts, with no surprise charges.
Pricing discussed by phone when possible
For an emergency call, the price depends mainly on the type of problem: a clogged sink, an overflowing toilet, a blocked main drain or a sewer backup. Access, the severity of the backup and what is described over the phone can also change the work needed.
For most emergency drain calls, pricing can be discussed by phone after a few questions. If the situation on site is different from what was described, we explain it before starting. To explain the emergency and confirm the next step, call 514-829-7514 or text 514-829-7514.
