North Willoughby runs from 1880s stock — Rosewall, a two-storey sandstone Georgian home, dates from that decade — through to modern apartments, at 52.2% houses, 16.9% semis and 29.4% flats. Pipe age varies by decades between neighbours. Relining suits most of what is found here, but which properties genuinely need it is a question the camera answers, not the street. On the villa and townhouse blocks there is an extra wrinkle: a shared line means shared agreement before any work.
It depends on the vintage, and this suburb has four of them. Victorian and Federation runs show classic joint failure; the townhouse blocks show shared lines with damage that affects several homes at once; the newer apartment stock rarely needs lining at all.
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.
Mature gardens over the older housing, with a century of planting on some blocks. On the townhouse developments what sits above is often common landscaping and shared driveways, which brings more owners into the reinstatement conversation than a single property would.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
Sloping ground typical of the sandstone ridges and gullies that shape the whole Willoughby area. Gully sites make a trench deeper and its reinstatement harder, which steadily widens the gap between the two options as the fault gets further from the house.
North Willoughby sits in the City of Willoughby, postcode 2068.

Everything from 1880s jointed earthenware to modern PVC, sometimes on the same run where a property has been extended. The oldest sections are the strongest relining candidates; the newest rarely need it at all.
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 mortared joints, mature garden overhead.
Fewer owners to negotiate with when nothing has to be dug up.
Trench depth and reinstatement both worsen with 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 North Willoughby 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 a shared line, a liner also settles a recurring dispute — a jointless pipe stops producing the annual argument about whose blockage it is and who pays for it.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to North Willoughby:
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 townhouse block it means common driveways and landscaping stay in use, which is frequently what makes the difference to getting the work agreed at all.
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. Pipe age and how many owners are on the line. A shared run under common landscaping is straightforward technically and slower administratively, and the approvals are usually the critical path.
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 North Willoughby the host pipe is usually a good candidate: it depends on the vintage, and this suburb has four of them. Victorian and Federation runs show classic joint failure; the townhouse blocks show shared lines with damage that affects several homes at once; the newer apartment stock rarely needs lining at all.
Yes, and it is often the easier option to get agreed. Relining a shared line means no common driveway dug up, no landscaping removed and no residents displaced — so the objections that stall a trench job largely disappear. What still has to be settled first is what the line serves and how the cost is split, which the camera survey helps establish.
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.
