What sewer line repair involves
Your sewer lateral runs from the basement cleanout, under the yard, to the City's sewer under the street. Repair begins with a camera inspection so we know the exact distance and depth of the damage. Then the options are laid out:
- Spot repair: excavate at the damaged section and replace a short length of pipe.
- Section replacement: replace a longer run where several joints have failed.
- Full lateral replacement: new pipe laid from the foundation out to the lot line when the old line is failing throughout.
Whether trenchless methods suit your line depends on its material, how badly it has collapsed and what sits above it. We will say plainly if they do not.
Why North York houses need it
Many postwar North York homes still drain through clay tile or early cast-iron laterals. That clay joints let in roots from mature maples and willows planted decades ago, and freeze-thaw cycles shift soil around the pipe. Clay-heavy soil in parts of the area holds water and moves seasonally, which can open joints or create sags that collect waste.
Plumber's tip: The portion of the lateral under City property is the City's responsibility. If the camera shows the damage past your property line, we tell you and you can contact 311. Questions? (365) 517-5705.
How we write up the job
- Camera footage reviewed with you, damage marked by distance from the cleanout.
- Locate and mark the line on the surface.
- Utility locates arranged before any digging.
- Permit pulled where the work requires one.
- Repair, inspection where required, backfill and surface restoration noted on the order.
Driveways, interlock and landscaping above the line are part of the scope discussion before work begins, not a surprise afterward.
Signs you should call
- The basement floor drain backs up more than once a year.
- Roots return within months of a clearing.
- A soft or sunken patch over the line in the front yard.
- Sewer smell in the basement with no obvious cause.
- A camera report from a previous company showing a break.
If a backup has already happened, read about tree root removal, and consider whether a sump pump replacement belongs on the same work order.
Costs and what affects them
Depth, length of the damaged run, what has to be removed above it, pipe material and permit requirements all change the price. A shallow spot repair under lawn is a very different job from a full replacement under a driveway. We price each from the camera findings and give you the figure in writing.
Before the dig day
Move vehicles off the driveway, keep pets inside and clear the basement area around the cleanout. If the house has a backwater valve, we note its location so it is protected during the work. Plan on limiting water use while the line is open; we tell you exactly when it is safe to flush again.

Your questions on this one
Does a sewer repair need a permit line?
Many sewer repairs and replacements in Toronto require a plumbing permit. We confirm it for your job and pull it where needed.
How long will my driveway be open?
It depends on the depth and length of the repair. We give an estimated schedule on the work order before digging starts.
