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

The gullies around Pymble hold blue gum and turpentine high forest — trees large enough that their roots fill a pipe rather than thread through it, and large enough to regrow into an open joint faster than garden planting does. Cutting them restores flow and leaves the entry point. On vegetation this size, sealing the joint is the difference between an annual visit and a repair.
Root masses large enough to fill the pipe rather than thread through it. Blue gum and turpentine high forest in the gullies produces trees on a different scale from garden planting.
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.
Large blocks with long private runs under high forest canopy and Sheldon Forest on the Turramurra boundary. Reinstating a trench under trees like these is a decade-long proposition.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
Ridge-top country falling into the gullies that hold Sheldon Forest, with long falls from the house to the connection.
Pymble sits in the Ku-ring-gai Council, postcode 2073.

Federation-era earthenware under the older estate housing, long past its design life and under the largest root systems on the Upper North Shore.
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.
Cutting resets the clock; lining stops it.
Reinstatement is not a season’s work.
Trench depth climbs down the fall.
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 Pymble 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.
On this vegetation a liner is the difference between an annual visit and a repair — cutting resets the clock every season.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to Pymble:
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 high forest canopy and the gardens beneath it are untouched, on runs that would otherwise be trenched under trees decades old.
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 scale of the root mass and the length of the run. High forest regrows into an open joint faster than smaller planting, which shortens the payback on sealing it.
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 Pymble the host pipe is usually a good candidate: root masses large enough to fill the pipe rather than thread through it. Blue gum and turpentine high forest in the gullies produces trees on a different scale from garden planting.
Because of what they belong to. The gullies here hold blue gum and turpentine high forest — very large trees with root systems to match — and they regrow into an open joint faster than garden planting does. Cutting restores flow; sealing the joint with a liner is what actually ends the cycle.
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.
