Cremorne Point is 79.9% apartments on a narrow finger of land with a single road in and out, and its buildings run long service lines down to the main. Both facts push the same way. A long aged stack is a strong lining candidate, and on a peninsula where every visit carries an access cost, doing the job once properly is the economy rather than the extravagance.
A long aged stack with the build-up at its base and the reported symptom several floors above. Long service runs from the buildings down to the main are the other consistent finding.
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 buildings, common areas and harbourside reserve planting running the length of the point. There is very little here that can be dug without inconveniencing someone or removing something protected.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
A narrow peninsula falling steeply on both sides, reached by one road. Plant has to come in and spoil has to go back out the same way, which is priced into every trench and none of a liner.
Cremorne Point sits in the North Sydney Council, postcode 2090.

Largely older strata stock built out through the last century, with long runs of aged stack pipe as the characteristic condition. Long and aged is exactly the profile where a continuous liner outperforms a patched replacement.
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.
The longer the run, the worse excavation compares.
Every return visit carries the same access cost.
Protected foreshore vegetation is not reinstatable.
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 Cremorne Point 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.
Doing it once properly is the economy here. Returning to Cremorne Point a second time carries the same access cost as the first.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to Cremorne Point:
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 plant brought down a single-access peninsula, and reserve planting along the point left untouched.
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. Run length and peninsula access. One road in and out means every visit costs the same to arrange, which is an argument for doing the whole run rather than the failed section.
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 Cremorne Point the host pipe is usually a good candidate: a long aged stack with the build-up at its base and the reported symptom several floors above. Long service runs from the buildings down to the main are the other consistent finding.
On Cremorne Point, usually the whole run. The buildings here have long stacks and long service lines to the main, and access to the peninsula is via one road — so a second visit costs roughly what the first did. Where the survey shows the rest of the line is genuinely sound we will say so, but sectional repairs are a false economy on sites like these.
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.
