Diagnosed before it's quoted.
A damaged sewer line is the plumbing problem people put off longest and regret most. It’s out of sight, the early symptoms look like an ordinary blockage, and by the time it’s obvious the repair is larger than it needed to be.

Voyager repairs sewer lines across the North Shore — diagnosed on camera first, with the no-dig option used wherever the pipe allows it.

The North Shore’s older suburbs have a specific combination: clay sewer pipes laid decades ago, and very large trees.

Describe what’s happening and we’ll tell you straight — including when the simple fix is the whole job.
Camera first. Nothing gets quoted before a CCTV inspection establishes what’s actually wrong, where it is, and how deep. Sewer repair quotes given without one are guesses.
Then, depending on the finding:
Pipe relining — where the host pipe is intact enough to form a liner against. No excavation in most cases, a jointless repair, and your garden stays where it is. This is the preferred option wherever it’s viable.
Section replacement — where a length has collapsed or the fall is wrong. Excavation limited to the affected section rather than the whole run.
Full replacement — where the line has failed along its length. The largest job, and the one worth confirming with a camera before anyone commits to it.
You’ll be given the option that fits the pipe, with the reasoning, and a fixed price before work starts.

Sewer lines on North Shore properties often run under established gardens, driveways, paving or between closely-spaced houses. That’s usually what determines the cost — not the pipe.
It’s also the strongest argument for relining where the pipe permits it: the excavation and reinstatement is frequently the largest line item in a dig-and-replace job.

In unit blocks the sewer line is often shared, and the first question is usually where the fault is and whether it’s common property. A camera inspection with the location and depth marked is what settles that. Voyager works with strata managers and building managers across the North Shore and can provide the footage and a written report.

The strongest signals are recurrence and scope. A one-off blockage in a single fixture is usually local. The same blockage returning, or several fixtures affected together, points at the main line. A camera settles it.
Often, yes — that’s what relining is for. Whether it applies depends on the pipe’s condition, which is what the camera establishes.
Generally the property owner is responsible for the line within the boundary, with the water authority responsible beyond it — but the specifics depend on the property and the connection point. An inspection that marks the fault’s location is what determines whose problem it is.
It varies more than most plumbing work, because access usually dominates. A short relined section and a full replacement under a driveway are very different jobs. Priced by the job, quoted after the camera, fixed before work starts.
Sewage actively backing up is urgent — call the 24/7 line. A cracked line that’s causing occasional slow drainage isn’t an emergency, but it doesn’t improve, and repairs get more expensive as the pipe deteriorates.
Yes. A liner needs a sound host pipe. Where a section has collapsed, that part needs replacing, and you’ll be shown why on the footage rather than asked to take it on trust.
