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

East Lindfield is 87.9% separate houses on eastern slopes running down towards Middle Harbour with Garigal National Park on the boundary. Its drainage went in with the housing and is now around seventy years old, under gardens that have had exactly as long to grow over it. That is the standard relining case, and the eastern fall makes the trench alternative worse.
Roots from the Garigal boundary in post-war jointed pipe, with the fault below the house on the eastern fall. In the 11.7% unit band, an ordinary stack build-up instead.
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 post-war gardens, with national park beyond. The 11.7% of dwellings in units bring the different argument of not opening a building.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
Eastern slopes towards Middle Harbour, where the fault is usually well below the house and the trench deepens as it travels.
East Lindfield sits in the Ku-ring-gai Council, postcode 2070.

Post-war jointed earthenware of consistent age, with newer stack material in the small apartment band.
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.
Sound barrel, failed joints — the ideal host.
Reinstatement is measured in years.
Root entry recurs unless the joint is sealed.
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 East Lindfield 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.
Seventy-year-old drainage rarely fails in only one place, so sealing the run rather than the metre is usually the better value.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to East Lindfield:
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 a garden as old as the drainage stays where it is, and no building is opened in the unit stock.
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. Whether it is a house or a unit, then how far down the slope the fault sits. The two are priced on completely different bases.
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 East Lindfield the host pipe is usually a good candidate: roots from the Garigal boundary in post-war jointed pipe, with the fault below the house on the eastern fall. In the 11.7% unit band, an ordinary stack build-up instead.
It narrows the excavation options rather than the repair. Established native root systems sit immediately against private drainage on East Lindfield’s park-boundary blocks, and digging towards a national park boundary is constrained. Relining is installed through an existing access point and is unaffected by either.
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.
