CCTV survey: $300–$750
Stands alone and is credited against the works by most operators. Without it nobody can price a liner honestly.
CCTV Surveyed, Then Relined
No-Dig Drain
Repairs In
Greendale
A cracked or root-damaged drain does not have to mean a trench through the garden. A resin liner is cured inside the existing pipe from an access point you already have, sealing every joint along the run, and the surface above is never touched.

Why No-Dig Suits The Drains In Greendale
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.
Why patching one joint rarely holds here
On stable ground a short patch over a single defect is often the proportionate repair. On reactive soil it frequently is not, because the movement that opened one joint has been working on every other joint in the same run for the same number of years.
That is worth knowing when you compare quotes. The cheaper patch can be the right call, but on this ground the full-length liner is more often the one that ends the problem rather than relocating it a metre.
Infiltration on a high water table
Where the water table sits close to the pipe, every open joint is an entry point. The line runs fuller than it should year-round, silt comes in with the water, and the system behaves as though it is undersized when it is simply leaking inward.
Greendale is a semi-rural suburb on Sydney’s south-western edge (postcode 2745), where acreages and farmland roll along Greendale Road between Wallacia, Luddenham and Bringelly toward the Nepean River. Long private drain runs and older farmhouse plumbing make blockages out here a specialist job.
Sealing the run changes that immediately, and it is one of the clearest before-and-after results relining produces. It is also the case most often missed, because nothing looks broken from the surface.
Joints, not pipe: what is actually failing
On a clay line the barrel is usually fine. What has gone is the mortar or rubber ring at each joint, and there is one every few hundred millimetres, which is a great many small openings after sixty or eighty years in the ground.
Greendale’s heavy clays swell in the wet and shrink in drought, flexing buried pipes until joints crack and let soil and roots in.
That matters for the quote. You are not replacing a pipe, you are sealing a long series of joints, and a liner does the whole run at once rather than patching them one at a time.
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.
Big rain events wash silt and debris off open paddocks into stormwater drains and culverts, choking them right when they’re needed most.
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.
What the camera has to show first
Root intrusion is not automatically a relining job. If the roots are fine and the pipe behind them is sound, a cut and jet with a maintenance interval can be the right call for years.
What moves it to relining is structural: an open joint you can see daylight through, a cracked barrel, or a run that has been cleared repeatedly at shortening intervals. Anyone quoting a liner without showing you the inside of the pipe is guessing, and you should ask for the footage.
What it costs in Greendale
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.
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.
What Actually Happens
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.

Relining, Answered Properly
The questions that come up before every relining job, answered with real numbers.
Relining is priced per metre and the range across Sydney in 2026 is roughly $500 to $900 a metre for a domestic sewer, with junction reinstatement and access usually quoted separately. A short patch repair over a single defect commonly lands between $1,500 and $4,000, and a full-length domestic run more often sits between $6,000 and $15,000. The honest comparison is not liner against nothing: it is liner against excavation plus reinstating whatever sits on top of the pipe.
Usually, but not always, and anyone who says always is selling. Relining wins wherever something valuable sits above the pipe: a driveway, established garden, paving, a building, or trading days you cannot afford to lose. Excavation wins on an open lawn with a shallow line, and it is the only answer where the pipe has collapsed, lost its fall or been crushed out of round. A camera survey is what tells you which case you are in.
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.
Often not, and it is worth knowing when comparing quotes. On stable ground a short patch over a single defect is proportionate. On reactive soil the movement that opened one joint has been working on every other joint in the same run for the same number of years, so the full-length liner is more often the repair that ends the problem rather than moving it a metre.
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.
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.
Yes, along the relined length. Roots do not attack sound pipe, they find a way in through an open joint or crack, and a liner is continuous with no joints for them to exploit. Cutting roots out clears the pipe but leaves the entry point exactly as it was, which is why jetted lines tend to reblock on a predictable interval.
