No-dig pipe repair on the Lower North Shore.
Cracked or root-damaged pipe repaired in place in Longueville — a new liner cured inside the old pipe, so an established garden never has to come up.

Longueville is 98.8% separate houses with no semis at all, on a peninsula between Tambourine Bay and Woodford Bay. Because it developed from the 1870s and has been rebuilt selectively ever since, four distinct housing eras sit on the same peninsula — so what is under one property tells you very little about the next. Lining suits the older runs particularly well; the camera is what identifies which they are.
Roots into an aged joint on a long run to one of the two bays, and frequently a splice where a rebuild joined new pipe to old. Four housing eras means little consistency.
Because putting the garden back costs more than fixing the pipe. This is the part of a drainage repair people do not price until an excavator is already on site.
Established gardens on large blocks, with bushland and river frontage on both bays. On generous blocks the run crosses a great deal of ground worth keeping before it reaches the connection.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
A peninsula with steep falls to two bays, eight kilometres from the CBD. Which bay a property drains towards changes the run, and on large blocks those runs are long.
Longueville sits in the Municipality of Lane Cove, postcode 2066.

Anything from Victorian earthenware to contemporary PVC, sometimes spliced on the same run where a house has been extended. The junction between two vintages is a common failure point.
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 oldest pipe here is the best lining candidate.
A liner unifies a run that has been patched piecemeal.
Trench cost scales with length and depth.
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 Longueville 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.
Lining across a splice unifies two vintages into one continuous run, removing the junction that was going to fail next.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to Longueville:
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. On a large block falling to a bay it means nothing crosses the garden and no spoil comes back out through it.
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 reinstatement on large established blocks. There are no semis anywhere in Longueville, so there is never a second owner to share it with.
Per metre, no — excavation is cheaper per metre. Overall it usually is. The dig figure rarely includes putting the garden back, and on established planting that is routinely the larger half of the job. 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. Which means the garden above it is not being opened again in ten years.
A typical residential run is a single day on site, and the resin cures in hours rather than days. The camera survey happens first, either on the same visit or beforehand — nothing about a relining job should be quoted from the surface.
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 Longueville the host pipe is usually a good candidate: roots into an aged joint on a long run to one of the two bays, and frequently a splice where a rebuild joined new pipe to old. Four housing eras means little consistency.
No. Longueville records no semi-detached dwellings at all — 98.8% separate houses — so party-wall drainage does not arise. Every private line serves one property. That simplifies responsibility, but it also means the whole cost of a repair sits with one owner, which is worth weighing when comparing a permanent liner against a trench.
Through that section, yes. Roots enter at joints and cracks; a liner is continuous and seals them, so the entry point is gone. Roots can still find a different fault further along an old line, which is why the survey covers the whole run rather than only the section that failed.
Camera survey first, a fixed price agreed before the work starts, and no excavation.
