Survey first: $300–$750
A recorded camera run with distances marked. Yours to keep, and usually credited if the work goes ahead.
CCTV Surveyed, Then Relined
No-Dig Drain
Repairs In
Wahroonga
We camera the line first, show you what is actually wrong, and then tell you whether relining is the right answer. Often it is. Where the pipe has collapsed or lost its fall, it is not, and we will say so rather than sell you a liner that disappoints.

When A Liner Is The Right Repair In Wahroonga
The failure that brings most people here is not a broken pipe. It is a joint. Older drainage is laid in short lengths, so a single run has a great many joints, and after decades of ground movement and root pressure they open a fraction at a time until something backs up.
A liner seals all of them in one pass, which is why it changes the pattern rather than resetting it. Cutting roots out clears the pipe and leaves the way in exactly as it was, and the interval to the next blockage is set by how fast they grow back.
Layers of previous work, and what the camera finds
An older house is rarely on one generation of drainage. It is on three or four, joined wherever a bathroom moved or an extension went on, and the transitions between materials are where most faults sit.
A camera run on a property like this is genuinely diagnostic rather than a formality. It is common to find a sound original clay run, a poor 1970s junction, and a modern PVC section all on the same line, each needing a different answer.
Long runs and where the access points sit
Properties on a slope often have long drainage runs, sometimes crossing the whole block to reach the main. The practical questions are where the inspection openings are and whether the liner can be drawn through in one length or needs a second access.
That is worth establishing before quoting. A single long run costs less per metre than the same distance broken into stages, and the difference is decided by access, not by the pipe.
Old is not the same as beyond saving
People are often surprised that a drain laid before the war is a relining candidate rather than a replacement. Age alone does not decide it. A clay line with a sound barrel and tired joints is close to the best case for a liner.
The cases that genuinely need excavation are different: a collapsed section, a run that has lost its fall, or a pipe crushed out of round. A camera separates those in an hour, and the answer changes the cost by a multiple.
Groundwater going the wrong way
An open joint leaks in both directions. On a low-lying block that means stormwater and groundwater entering the sewer through cracks, which is called infiltration, and it quietly overloads a line that would otherwise cope.
Heavy Upper North Shore downpours send leaf litter and runoff surging across large gardens, choking stormwater pits and soakwells that overflow toward the house.
It shows up as a system that backs up in wet weather and behaves perfectly in dry. If that is the pattern, sealing the run is the fix, and no amount of clearing will reproduce the result.
Why earthenware is the ideal host for a liner
The suburb’s grand older homes often still run original earthenware and cast-iron pipes that corrode, crack and collapse, letting roots and debris slow every drain.
Clay is rigid, round and predictable, and that geometry is exactly what a liner wants. The resin sleeve cures hard against a barrel that holds its shape, and the short pipe lengths that make clay joint-heavy are the same joints the liner seals in one pass.
So the material that causes the most recurring blockages in older streets is also the easiest to repair properly without digging. That is a genuinely lucky combination and it is why relining suits this housing stock so well.
Stormwater lines are relinable too
Most people associate relining with sewers, but stormwater suffers the same failures and reline just as well: cracked lengths, open joints, roots, and sections that have silted because the fall has flattened. On a property that floods in every serious downpour, the line is often the reason rather than the rain.
The camera run matters more here than anywhere. Clearing a surcharging pit at the height of a storm tells you almost nothing; the same line inspected on a dry day tells you whether you have a blockage or a defect.
What it costs in Wahroonga
Liner, $500–$900 a metre
The prevailing 2026 Sydney range for residential sewer relining.
Single defect patch, $1,500–$4,000
Proportionate for one fault in a sound run. We will recommend it over a full liner when that is what the camera shows.
Full-length reline, $6,000–$15,000
For a run failing along its length, which on old clay is the common finding.
The dig-up alternative, from $2,500 upward
Plus reinstatement. On a bare lawn it can win. Under anything you would miss, it usually does not.
These are market ranges, not our price. Nothing is quoted before the survey, and nothing starts before you agree it. Figures here are indicative of the 2026 Sydney market rather than a quote from us, you get your own number as a fixed price before any work starts.
How A Relining Job Runs
Step 01
Step 01
Look Before Quoting
Nothing is priced until a camera has been down the line. The survey is recorded, distances are marked from a known point, and the footage is yours.
Step 02
Decide What It Needs
A single defect in a sound run wants a patch. A run failing along its length wants a full liner. A collapsed or sagging section wants excavation. The camera decides, not the quote.
Step 03
Install The Liner
Jet clean, install through the existing opening, cure in place. Water is off for part of the day and nothing above the pipe is disturbed.
Step 04
Prove It Is Right
Junctions reinstated, final camera run, and the compliance paperwork where the work is notifiable. You keep both recordings.

Relining, Answered Properly
The questions that come up before every relining job, answered with real numbers.
Most domestic relining is a single day on site: set up at an existing access point, jet and camera the line clean so the liner bonds to pipe rather than debris, install, cure, then reinstate the junctions and camera it again. Water is off for part of the day. Larger or commercial runs are staged, and are often scheduled overnight or across one closed day so the premises can trade.
Slightly, and it rarely matters. A liner reduces the internal diameter by a few millimetres, but the cured surface is far smoother than aged clay or concrete, so flow capacity is typically maintained or improved. Where diameter genuinely is marginal, the camera survey shows it before anyone quotes.
No. A liner takes the shape of the pipe it cures inside, so it cannot correct a run that has sagged into a belly or lost its fall, and it has nothing to line against where a section has collapsed. Badly deformed or crushed pipe needs replacing. What relines well is the common case: a sound barrel with cracked or open joints, which is most older clay drainage.
Because it is rarely on one generation of drainage. Original clay, a 1970s junction and a modern PVC section on the same line is a normal finding, and the transitions between them are where most faults sit. A slower survey is what prevents relining a run that actually needed one junction rebuilt.
Often, and it costs less per metre when it can. Whether it is one length or staged is decided by where the inspection openings sit and whether the liner can be drawn through, not by the distance itself. Properties on a slope frequently have long runs crossing the block, so it is worth establishing access before quoting.
Sometimes, and the camera decides it. If the line is cracked or the joints are open, sealing the run fixes it. If the problem is a flattened fall, a belly or an undersized line, relining will not correct the shape and excavation is the honest answer. Book the inspection between storms, not during one: a surcharging pit at the height of it costs more to look at and tells you less.
Often yes, and that surprises people. A well laid clay line of that age usually still has a sound barrel; what has gone is the mortar or rubber at each joint, and there is one every few hundred millimetres. You are sealing a long series of small openings, not replacing a pipe, and that is exactly what relining is for.
