North Sydney is 84.4% apartments with very little private drainage, and it changed character completely in the 1970s when the towers went up. Excavation in a centre like this brings traffic management, restricted hours, pedestrian access and commercial reinstatement — costs that have nothing to do with the pipe. Lining avoids the lot, and does it without taking a building out of service.
A loaded stack in a 1970s-era tower, on a network also carrying substantial commercial load. With very little private drainage anywhere, essentially every finding is in a building.
Because opening up a building is a different order of disruption. This is the part of a drainage repair people do not price until an excavator is already on site.
Occupied residential and commercial floors, basement plant and public domain. There is almost no soft ground in North Sydney to open, and what there is sits in public space.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
About 83 metres above the harbour, three kilometres from the CBD and directly across the bridge. Density, not terrain, is the constraint on every job here.
North Sydney sits in the North Sydney Council, postcode 2060.

Laid out as the St Leonards township in 1836 and incorporated in 1890, but the suburb standing today is largely a product of the 1970s onward — towers built in one burst, now reaching the same maintenance milestones together.
No trench, no spoil, and nothing above the pipe disturbed. The whole job runs through an existing access point.
The line is inspected end to end so the damage is located and measured. Nothing is quoted from the surface.
Roots are cut out and the pipe wall is jetted back to bare material — a liner will not bond to a coated pipe.
A resin-saturated liner is drawn into position through an existing access point and inflated against the host pipe.
The resin hardens in hours rather than days, forming a new pipe inside the old one with no joints for roots to re-enter.
Any branch lines are cut back open robotically, and a final camera pass confirms the result.
Not every damaged pipe should be relined, and we will say so. These are the cases where it genuinely wins here.
Traffic management alone can exceed the repair.
A single access point, building still functioning.
One authorised job beats a decade of reactive callouts.
Relining costs more per metre than excavation. It is usually cheaper overall, and this is why:
| Dig and replace | Relining | |
|---|---|---|
| Excavation | Trench the full length, remove and replace the pipe, backfill | None — the work runs through an existing access point |
| What comes up | Lawn, garden, paving, driveway or slab above the line | Nothing |
| Time on site | Days on a long or deep run | Usually one day for a typical run |
| Reinstatement | Priced separately and often the larger half of the bill | Not applicable |
| Result | New pipe, with joints | A jointless liner inside the host pipe |
| Design life | Depends on material and bedding | 50 years on a correctly installed liner |
The per-metre comparison is the one that misleads. Excavation quotes routinely exclude spoil removal and reinstatement, which is where a dig job gets expensive — and on some properties the reinstatement is simply not possible at any price.
These are typical ranges across the Sydney market — not Voyager’s price list, but a realistic yardstick to judge any quote against, including ours.
| Pipe relining, per lineal metre | $450 – $800 |
| Pipe relining, typical whole job | $4,000 – $10,000 |
| Patch repair, single damaged section | $1,500 – $3,000 |
| Junction reinstatement | $300 – $600 |
| Excavate and replace, per metre | $300 – $600 |
| Driveway reinstatement after a dig job, per sqm | $100 – $200 |
| CCTV drain inspection | $250 – $550 |
| Cutting tree roots from a line | $400 – $1,200 |
Voyager prices by the job, not by the hour, so the number you approve is the number you pay. A camera survey happens before any figure is given — a quote for relining that has not looked down the pipe is a guess.
Most North Sydney properties that ring about relining need a camera first. We will tell you straight — including when clearing the line is the whole job.
A correctly installed liner carries a 50-year design life, and it cures in hours rather than days — so the property is back in normal use the same week rather than the same month.
North Sydney’s towers went up in one burst and reach maintenance milestones together, which makes a durable repair worth more than a cheap one across a portfolio.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to North Sydney:
No. That is the whole point of it. The liner is drawn in through an existing access point — usually an inspection opening or shaft already on the property — and cured in place against the old pipe. It means no road opening, no footpath closure and no building taken out of service.
Across the Sydney market, relining runs about $450–$800 per lineal metre, with a typical whole job landing between $4,000 and $10,000 and a single-section patch around $1,500–$3,000. Those are market ranges rather than Voyager’s price list. Access, hours and public domain. Excavation here brings traffic management and restricted working hours before it brings a shovel, and none of that applies to a liner.
Per metre, no — excavation is cheaper per metre. Overall it usually is. A dig figure in a building also has to carry access through occupied lots, common areas out of use and works approvals — none of which appear on the per-metre rate. On some properties the reinstatement is not possible at any price, which settles it entirely.
A correctly installed liner carries a 50-year design life. It outlasts what it replaced because it has no joints along its length — and joints are where roots get in, where ground movement opens a gap, and where old earthenware fails first. For an owners corporation that is the relevant number — one authorised job against another decade of reactive callouts on the same line.
A typical residential run is a single day on site, and the resin cures in hours rather than days. Coordinating building access and notifying affected lots usually takes longer than the installation does.
Most can, but not all — and we will say so rather than sell you something that will not work. A pipe that has collapsed completely, or lost so much of its shape that there is nothing left to line against, needs replacing. In North Sydney the host pipe is usually a good candidate: a loaded stack in a 1970s-era tower, on a network also carrying substantial commercial load. With very little private drainage anywhere, essentially every finding is in a building.
Because the digging is the smallest part of it. In a commercial centre this dense, a trench brings traffic management, pedestrian access, restricted working hours and reinstatement of public domain — costs attached to the location rather than the pipe. Relining runs through an existing access point and avoids all of them.
The owners corporation, where the line is common property — which generally means any pipe serving more than one lot. We deal with the strata or building manager directly and provide the camera footage they need to approve the work. Where the line serves only your lot, it is your decision.
Camera survey first, a fixed price agreed before the work starts, and no excavation.
