Sewer Backup Services in North York

Urgent response when wastewater backs up into basements, floor drains or fixtures.

Basement floor drain being cleared

A sewer backup is one of the most stressful plumbing problems a homeowner can face. Wastewater coming up through a basement floor drain, shower or toilet is unpleasant and can cause serious damage quickly.

We help get the line flowing again, determine whether the cause is a blockage in your plumbing or a broader issue, and talk through measures that may reduce the risk of it happening again.

What a sewer backup looks like

  • Dirty water rising from the basement floor drain
  • Toilets on the lowest level bubbling or overflowing
  • Sewage smell throughout the lower floor
  • Water backing up during or after heavy rain

How we approach sewer backup services

  1. 1

    Stop the inflow

    We advise you to stop using water in the house to prevent more wastewater entering the line.

  2. 2

    Clear the main line

    The blockage is cleared through an accessible cleanout or fixture.

  3. 3

    Find the cause

    We check for roots, grease, debris or pipe damage, and note whether storm conditions were a factor.

  4. 4

    Discuss prevention

    We explain options such as backwater valves, which may be eligible for City of Toronto subsidy programs.

Safety advice

  • Treat backed-up water as contaminated. Wear gloves and boots, and avoid touching your face.
  • Do not use electrical devices in a flooded basement. Turn off power at the panel only if it is safe to reach.
  • Contact your insurance provider early and document the damage.

Sewer Backup Services FAQ

Is a sewer backup my fault or the city's?

It can be either. A blockage in your lateral is a private issue, while storm overload is a municipal one. Diagnosis helps clarify which.

What is a backwater valve?

A backwater valve is a device installed in the main drain that helps prevent sewage from flowing back into the house when the municipal sewer is overloaded.

Do you handle cleanup?

We focus on the plumbing. For water damage restoration, you may need a dedicated restoration company, often arranged through your insurer.
