No-dig pipe repair on the Lower North Shore.
Cracked or root-damaged pipe repaired in place in Turramurra — relining works from existing access points, which matters on blocks machinery cannot reach.
No callout fee on eligible jobs · Free quotes
Turramurra sits at about 170 metres on hilly ground with three separate bushland areas around it, and its Federation Queen Anne housing drains through pipe laid in the early 1900s. A century of ground movement on that terrain is what opens mortared joints — and replacing them with another jointed pipe leaves the same failure mode in place for the next century. A liner does not have joints to open.
Roots through a joint in early-1900s earthenware on ground that has been moving under it for a century. With three bushland areas around the suburb the roots can come from any direction.
Because getting machinery to the fault is the expensive part. This is the part of a drainage repair people do not price until an excavator is already on site.
Established gardens on Federation blocks, with three bushland areas around the suburb and Sheldon Forest on the Pymble boundary.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
Hilly country at around 170 metres where a century of ground movement has been working on the drainage since it was laid.
Turramurra sits in the Ku-ring-gai Council, postcode 2074.

Early-1900s earthenware under Federation Queen Anne housing, with the 27.2% unit stock bringing modern stack material.
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.
A liner bridges what movement will keep reopening.
Trenching and reinstating on a slope is slow.
Roots from any direction unless 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 Turramurra 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 bridges joints that ground movement will keep reopening — replacing with another jointed pipe leaves the same failure mode for the next century.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to Turramurra:
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 trench and reinstatement on hilly ground, on blocks where both are slow.
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 condition of Federation pipe, which narrows the method choices, and hilly ground, which makes reaching a fault and reinstating afterwards both expensive.
Per metre, no — excavation is cheaper per metre. Overall it usually is. The dig figure rarely includes getting plant to the fault and spoil back out, which on constrained blocks is the bulk of the cost. 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 matters most where returning to the property is itself expensive.
A typical residential run is a single day on site, and the resin cures in hours rather than days. On a constrained block, getting equipment into position is the part worth planning; the installation itself is quick.
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 Turramurra the host pipe is usually a good candidate: roots through a joint in early-1900s earthenware on ground that has been moving under it for a century. With three bushland areas around the suburb the roots can come from any direction.
Ground movement. Turramurra is hilly country at around 170 metres, and a century of movement under Federation Queen Anne housing works on mortared earthenware joints — rain is usually when one that was holding reopens. It can present as a blockage, as ingress, or both, which is why the survey comes before the method.
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.
