No-dig pipe repair on the Lower North Shore.
Cracked or damaged pipe repaired in place in Kurraba Point — relining a stack or a shared line without opening walls, slabs or common areas.

Kurraba Point is 79.6% apartments across just 647 dwellings, largely in older walk-up blocks from the early-twentieth-century expansion of this stretch of harbour. Their stacks are cast iron or earthenware, narrowed by decades of use and now carrying loads including wipes they were never designed for. Repeated aggressive clearing on pipe like that is a risk in itself — a liner restores the bore and reinforces the host at the same time.
A narrowed cast iron or earthenware stack in an early-twentieth-century walk-up, coated with decades of deposit and carrying loads it was never designed for.
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 walk-up buildings on a peninsula with harbour on three sides. Opening a stack in a small older block affects a large proportion of its residents.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
A small peninsula falling to the water on three sides, where getting equipment to a building is planned rather than assumed.
Kurraba Point sits in the North Sydney Council, postcode 2089.

Early-twentieth-century cast iron and earthenware stacks rather than PVC. Older material narrows faster and tolerates less, which is precisely the case where lining beats repeated mechanical clearing.
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.
Lining restores bore without stressing the host.
Fewer lots, same inconvenience.
Every visit costs the same to arrange.
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 Kurraba 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.
A liner reinforces the host pipe as well as restoring its bore, which on aged cast iron is the more important of the two.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to Kurraba 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. In a small walk-up it means no riser opened in a building where that would affect a large share of the residents.
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. The material and condition of the host pipe, plus getting equipment onto a peninsula with harbour on three sides. Older stacks need a gentler method and a survey first.
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 Kurraba Point the host pipe is usually a good candidate: a narrowed cast iron or earthenware stack in an early-twentieth-century walk-up, coated with decades of deposit and carrying loads it was never designed for.
It is generally the safer option. Many Kurraba Point walk-ups carry cast iron or earthenware stacks that have narrowed over a century, and repeated mechanical clearing on pipe like that is a risk in itself. A liner restores the bore and reinforces the host rather than stressing it — but the camera survey comes first, because condition decides whether it is viable.
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.
