  • Parts matched to the pipe already in your walls
  • A written note of what changed and why
  • Floors protected and the work area left tidy
  • The real cause pinned down ahead of any cutting

  • Soggy patch on the front lawn
  • Toilets on the lowest floor bubble

Symptoms of a failing lateral

  • Repeated main line backups, even after cleaning.
  • A soft or sunken patch on the front lawn along the line of the pipe.
  • Sewer smell in the basement with no dry traps to blame.
  • Roots showing up every time the line is cabled.
  • Rats near the foundation, which can travel through broken pipe.

In much of older Toronto, the lateral is clay tile laid in short jointed lengths. Postwar homes may have cast iron or a fibre pipe called Orangeburg, which flattens as it ages.

Private side versus City side

Your sewer lateral has two owners. The section from your house to the property line, roughly the sidewalk, is yours. From there to the main under the road is the City of Toronto's responsibility. If our camera finds the defect on the City side, you can report it to 311 and Toronto Water will investigate. Get the footage and a locate marking the distance from the cleanout. It saves time.

Before you dig. Ontario One Call must locate buried gas, hydro and telecom lines before any excavation. It is free, and required by law.

Spot repair or full replacement

A single cracked joint or one root intrusion close to the house can often be fixed with a spot repair: dig one hole, cut out the bad section, couple in new PVC. Where the whole run has multiple breaks, sags or flattened pipe, full replacement makes more sense. Trenchless lining can also work in some lines, sealing old pipe with a resin sleeve, but it needs a pipe that still holds its shape. We tell you which approach fits your pipe and why.

Permits, digging and restoration

Sewer work on private property needs a plumbing permit from Toronto Building, with an inspection before backfill. Digging in the City boulevard needs its own approval. Most jobs take one to three days. The yard is opened, the pipe is bedded in proper material, inspected, backfilled and compacted. Grass and interlock restoration may be part of the job or handled separately; we will spell that out up front.

How the job runs

  1. Ring the line

    Say what is dripping, backing up or banging. Water still flowing? We guide your hand to the valve first.

  2. Find the cause

    The plumber traces the fault, with a scope or gauge where one earns its keep.

  3. Pick the fix

    Options come in everyday language, and nothing starts until you choose.

  4. Repair & prove it

    We finish, run the water to prove it, wipe up and leave a short written record.

Calls we field, answered plainly

Can I add a backwater valve during sewer work?

Yes, and it is a good time, since the line is already open. Toronto has subsidized backwater valves in the past, so confirm the current program before you start.

How long does PVC sewer pipe last?

Properly bedded PVC lasts many decades and resists roots because its joints are glued or gasketed tight.
