Sewer Line Replacement near you

One backup doesn't justify a new lateral. The case for replacement builds when the camera footage and the home's history point the same way: the pipe as a whole, not one spot on it, has reached the end of its useful life.

The decision rests on the whole length of pipe, not the worst frame of video. Ask the contractor to go through the recording with you, point out each defect with its distance from the cleanout, and explain which defects a spot repair would leave behind. A lateral with one broken section and sound pipe on either side is usually a repair; one with defects scattered from the foundation wall to the property line is usually a replacement.

Slope is the other deciding factor. A new pipe laid in a trench can be set to an even grade, removing a belly for good, while a liner takes the shape of the old pipe and bursting follows its path, so a badly settled line may still hold water after a trenchless job. When contractors disagree, a second camera inspection by someone not quoting the work can settle it.

Every method ends with a working pipe; they differ in what gets dug up and what they can correct. Depth, soil, what sits above the line and other buried services all weigh in.

Before collecting quotes, find out where your responsibility ends. The City of Toronto owns the sewer line from the main on the street to the property line; the owner owns the part from the property line into the home. The City also says it doesn't replace or install sewer service connections on private property, so that section is the owner's to arrange. Other municipalities set their own rules, so check with yours, especially if the damage sits near the property line.

Replacing buried drain piping is permit work in many cities. Toronto, for example, issues stand-alone drain permits and lists repairs, replacement and additions of buried plumbing and drainage piping among the work they cover. Digging beyond the property line, under a sidewalk, boulevard or street, is a separate matter: that land belongs to the municipality, which generally does the work itself or sets its own approval, traffic control and restoration conditions. Every excavation also starts with a free locate of buried utilities, through Ontario One Call in Ontario or Info-Excavation in Quebec.

Toronto's Basement Flooding Protection Subsidy Program pays part of the cost of specific flood-protection work: a home plumbing assessment, installing or replacing backwater valves with their alarms, installing or replacing a sump pump with an alarm and battery backup, and severing and capping the foundation drain connection. The new lateral itself isn't one of the listed items, but a replacement is often the natural time to do the ones that are, since the drain is already exposed.

Conditions apply: the program is for registered owners of single-family homes up to fourplexes, contractors need a valid City business licence, a backwater valve needs a building permit, downspouts must be disconnected, and applications are due within two years of installation, with the original itemized invoices. Other cities run their own programs; see the backwater valve installation page.

Most replacements follow the same order, and knowing it helps you check that nothing gets skipped.

With the building drain already exposed, a replacement is the least disruptive time to add a main-line backwater valve, which would otherwise mean cutting the basement floor later. Its position decides which fixtures it protects and its access cover must stay clear; the backwater valve installation page covers types, placement and upkeep. Where the foundation drain is tied into the sanitary line, redirecting it to a sump pit is often weighed at the same time.

Ask for an accessible cleanout near the foundation wall, so future camera runs and cleaning don't mean pulling a toilet. Afterwards, keep new trees and large shrubs away from the pipe's route, and have the line looked at by camera if slow drains come back.
