No-dig pipe repair on the Lower North Shore.
Cracked or root-damaged pipe repaired in place in Lane Cove West — sealing the line against the ground rather than digging it out of it.
No callout fee on eligible jobs · Free quotes
Blackman Park sits on former landfill on the Lane Cove River, and parts of the suburb are on or near made ground. Ground that has been placed rather than formed settles, which is what pulls a line out of grade and opens joints — and it is also what makes excavation and backfilling in it unpredictable. A liner seals the run without disturbing ground that is still consolidating.
A line that has settled out of grade on or near made ground, or roots on the bushland and river frontage to the west. Trade waste characteristics in the industrial pocket.
Because the ground here is the problem, and digging into it makes it worse. 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 on the residential side, and industrial hardstand on Mars Road and Sam Johnson Way. Cutting industrial surfacing is a different cost base again.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
Former landfill on the river, bushland and river frontage to the west, and an industrial pocket in between. Made ground is the defining constraint and it affects every excavation decision here.
Lane Cove West sits in the Municipality of Lane Cove, postcode 2066.

Older detached streets on jointed earthenware; the industrial pocket on commercial systems with different obligations. Lines that have lost grade through settlement are a recurring finding rather than a rarity.
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.
Trenching in settling fill is unpredictable and slow.
Sealing the length is the fix, not clearing it.
Cutting and reinstating it is a builder’s cost, not a plumber’s.
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 Lane Cove West 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 ground that is still consolidating, a continuous liner tolerates further settlement far better than a newly jointed pipe would.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to Lane Cove West:
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 in settling fill near Blackman Park, and no cutting of industrial hardstand on Mars Road or Sam Johnson Way.
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. Which of the three it turns out to be. A line that has lost fall is not repaired by clearing it, and industrial work carries obligations domestic work does not.
Per metre, no — excavation is cheaper per metre. Overall it usually is. Excavating ground that is periodically saturated is slower, needs more support and backfills less predictably, and all of that is priced. 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. And because it is continuous, it keeps ground and storm water out along the whole run rather than at the point that failed.
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 Lane Cove West the host pipe is usually a good candidate: a line that has settled out of grade on or near made ground, or roots on the bushland and river frontage to the west. Trade waste characteristics in the industrial pocket.
In Lane Cove West that often means the pipe has lost its fall rather than caught something. Parts of the suburb sit on or near made ground — Blackman Park is former landfill on the Lane Cove River — and settlement pulls a line out of grade. Clearing works briefly; relining the run gives a smooth continuous bore that copes far better with ground still consolidating.
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.
