McMahons Point was working-class housing that has since been renovated extensively, and the combination is awkward: original pipe under new work that nobody wants to lift. At 23.6% semis and terraces there is also a good chance the run is shared. Relining reaches the damaged section through an existing access point, which is the difference between a repair and a demolition.
Original pipe under recent renovation more often than not, and on the terrace stock a run that crosses a boundary. The access is the problem far more than the pipe is.
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.
New kitchens, slabs, paving and landscaping over drainage that predates all of it. The reinstatement after a trench here is a builder’s cost rather than a plumber’s, and on recent work it is a substantial one.
A liner goes in through an opening that already exists. Nothing above the pipe has to move.
A peninsula between Berrys Bay and Lavender Bay with Blues Point at its southern tip, on slopes falling to both. Waste surfaces at the lowest relief point, which on this terrain says little about where the fault is.
McMahons Point sits in the North Sydney Council, postcode 2060.

Original working-class-era drainage under heavily renovated houses, with party-wall runs on the terrace stock and modern stack material in the 62.8% that are flats.
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.
Reached through an opening rather than by lifting new work.
Nothing excavated on either property.
Trench depth climbs quickly on these blocks.
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 McMahons Point 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.
Sealing the whole run matters where a property has been heavily renovated — nobody wants to be back inside the same finishes in five years.
Roots come back through joints. A liner has none.
Voyager covers the whole Lower North Shore. These are the closest to McMahons Point:
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 recent kitchen, slab or landscaped garden over the line stays exactly where it is.
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. What has been built over the fault. Reaching a line under a new slab or finished interior is demolition, and the reinstatement is a builder’s cost.
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 McMahons Point the host pipe is usually a good candidate: original pipe under recent renovation more often than not, and on the terrace stock a run that crosses a boundary. The access is the problem far more than the pipe is.
Usually, yes. Relining works from existing access points, so a damaged section under a slab, paving or new flooring can generally be repaired in place. It is a common situation in McMahons Point, where original working-class housing has been renovated extensively. The camera survey confirms whether it is possible before anyone discusses lifting anything.
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.
