Clay, combined sewers, backwater valves
On the island, 1920s to 1960s laterals are often still clay. Joints offset after freeze. Older boroughs share storm and sanitary on one main drain. A missing or stuck backwater valve lets sewage into the basement. We unclog, then film before we talk excavation.
Clay laterals on the island
Many homes still drain to the city on original clay. After freeze-thaw, the lowest fixture comes up first. Plateau, NDG, RDP, and PAT see the same offset joint.
Combined sewers and spring rain
Roots, freeze-thaw, camera on site
Plateau, Outremont, NDG street trees find clay joints. We unclog first, then film if the line needs it, for recurrence, a sale, or a wet basement.

Older Montreal laterals, written for this city
Here's what a customer had to say.
“Rain hit, the basement floor drain came up on Saint-Denis. They showed clay offset on camera, cleared the lateral, and explained the backwater valve we still needed. Price matched the estimate.”
Questions about drain cleaning in Montreal
Which line failed, and when we film the lateral.
Clay lateral or combined sewer, how do you choose?
The lowest fixture coming up after a freeze is often the clay lateral. Several drains plus rainwater in the basement is often the combined sewer and the valve. We confirm on site.
When do you film the lateral?
We unclog first. We film if the same drain clogs again, before a sale, or if the basement got wet. Video and a written report are part of the visit.
