CCTV survey: $300–$750
Stands alone and is credited against the works by most operators. Without it nobody can price a liner honestly.

Dulwich Hill
Relining turns a recurring drainage problem into a finished one. The joints that roots come through are sealed along the whole run, so there is no way back in, and nothing above the pipe gets disturbed to do it.

What Relining Actually Is In Dulwich Hill
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.
Doing the work without emptying the building
The reason excavation is painful in an apartment block is access. A line under a slab, a car park or a common courtyard means noise, disruption and lots that cannot use their bathrooms while it happens.
A liner installed from an existing access avoids nearly all of that. What still needs planning is the water shutdown, and buildings usually require notice for it, so the schedule matters as much as the method.
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.
Digging near the water is the expensive option
Excavation close to the foreshore brings problems that have nothing to do with plumbing: unstable saturated ground, dewatering, restricted access down a narrow lot, and reinstatement of landscaping that was not cheap to build.
The trenchless comparison is not repair against repair. It is repair against repair plus everything sitting on top, and on a waterfront block that second half is usually the bigger number.
Steep blocks are where no-dig earns its money
Dulwich Hill’s Federation homes were plumbed generations ago, and that old earthenware pipework cracks and sags as the ground shifts around it.
Excavating on a slope is a different job from excavating on the flat. Access for a machine is often impossible, the spoil has to go somewhere, trench walls need support, and reinstating a tiered garden or a retaining structure can cost more than the drainage work it was dug for.
Relining sidesteps all of it. The line is repaired from an existing access point, and the surface above stays exactly as it is. On a difficult block the saving is not marginal, it is often the difference between doing the job and deferring it.
After the second flood, stop clearing and look
Once is weather. Twice is a defect, and the second event is the point at which paying for a camera saves money rather than costing it.
What we are looking for is specific: a belly holding water, a joint that has opened, a section crushed by a vehicle crossing. Each has a different answer, and only one of them is relining. Knowing which you have is worth more than another clear.
Ground that moves, joints that open
Sitting low near the Cooks River, parts of Dulwich Hill cop slow-draining stormwater in heavy rain, backing up through choked pits and gullies.
Ground near water holds more of it, sits lower and moves more through the seasons than ground further up. Pipework laid decades ago has been flexed by that movement for its whole life, and joints open a fraction at a time rather than failing all at once.
It is why faults here tend to arrive as a slow decline rather than a sudden break, and why a camera often finds a run that is uniformly tired instead of one obvious defect. That pattern suits a full-length liner rather than a patch.
Patch or full length
A short patch, sometimes called a junction repair, seals one defect and is the proportionate answer when the rest of the run is sound and the ground is stable.
A full-length liner is right when the camera shows the same failure repeating along the run, which on an old clay line it usually does. Paying for a patch on a line with twenty tired joints is how people end up paying twice.
What it costs in Dulwich Hill
Relining, $500–$900 per metre
The usual Sydney range for domestic sewer. Access and junction reinstatement are normally quoted separately.
Patch repair, $1,500–$4,000
One defect in an otherwise sound run. The proportionate answer on stable ground, and the wrong answer on a line with twenty tired joints.
Full domestic run, $6,000–$15,000
Where the camera shows the same failure repeating along the length. Ends the problem rather than relocating it.
Excavation, from $2,500 plus reinstatement
The honest comparison. Cheaper on an open lawn, rarely cheaper under a driveway, paving or a building.

From Survey To Finished Liner
Step 01
Step 01
Camera The Line
A CCTV survey establishes the material, the diameter, where the defects are and how far they sit from the access. You see the footage, and it is what the quote is built from.
Step 02
Agree The Method
Patch or full length, and occasionally excavation instead. We will tell you when digging is the better answer even though it is the bigger quote.
Step 03
Clean, Line And Cure
The run is jetted so the liner bonds to pipe rather than debris, the liner is installed through the existing access, and it cures in place. Most domestic jobs are a single day.
Step 04
Reinstate And Re-Camera
Every branch the liner passed is reopened from inside, then the run is cameraed again so you can see it is continuous and the junctions are clear.
Not Sure If It Needs Relining At All?

What People Ask About Relining
Cost, lifespan, method, and the cases where a liner is the wrong answer.
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.
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.
Cured-in-place liners are generally rated at around fifty years, comparable to a new pipe and usually longer than the remaining life of the earthenware they are installed into. The reason the figure is that high is structural rather than promotional: a liner has no joints along its length, and joints are what fail. Most warranties on the workmanship run considerably shorter than the rated life of the material, so ask what you are actually being given.
With location, not demolition. Water tracks along beams and slab falls, so the lot reporting the damage is often nowhere near the lot with the fault. Camera and non-destructive location come first, and once the defect is measured from a known point the repair is a defined job rather than exploratory work in someone else's home.
No, that is the point of the method. The liner is drawn through an existing inspection opening and cured in place, so tessellated verandah tiles, original paving and a mature garden are never disturbed. On a period property the reinstatement is almost always more expensive than the pipe repair underneath it.
Where the water table sits close to the pipe, every open joint is an entry point for groundwater. The line runs fuller than it should year-round and silt comes in with the water, so the system behaves as though it is undersized when it is actually leaking inward. Sealing the run is one of the clearest before-and-after results relining produces.
Usually much better, because excavating on a slope is a different job from excavating on the flat. Machine access is often impossible, spoil has to go somewhere, trench walls need support, and reinstating a tiered garden or retaining structure can cost more than the drainage work itself. A liner is installed from an existing access and leaves the surface untouched.
