Camera inspection: $300–$750
The first and non-negotiable step. Most operators credit it against the works if you proceed.
Trenchless Pipe Relining
No-Dig Drain
Repairs In
Mortlake
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 Mortlake
Relining is a structural repair, not a cleaning method, and the distinction matters when you are comparing quotes. Jetting restores flow through a pipe that is still cracked. A liner restores the pipe.
That also means it is not always the answer. It cannot correct a run that has sagged or lost its fall, and it has nothing to line against where a section has collapsed. A camera survey separates those cases in about an hour, and the answer changes the cost by a multiple.
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.
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.
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.
Many of Mortlake’s established homes still run old earthenware and cast-iron pipes that crack and corrode after decades so close to the river.
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.
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.
Keeping the tree and fixing the drain
Removing a mature tree is expensive, often needs approval, and frequently does not solve it: the roots already inside the pipe do not leave when the trunk does, and the joint is still open for the next one.
Mature street trees and riverside gardens send roots hunting into old pipe joints, a top cause of recurring blockages here.
Relining lets both things be true at once. The garden stays as it is and the drain stops being a route to water. For most owners that is the whole appeal, and it is why no-dig gets specified on established blocks far more often than on new ones.
What the day looks like
Access is set up at an existing inspection opening, the line is jetted and cameraed clean so the liner bonds to pipe rather than to debris, the liner is installed and cured, and the run is cameraed again afterwards.
Most domestic jobs are a single day and the water is off for part of it. You get the before and after footage, and where the work is notifiable the compliance paperwork follows it.
What it costs in Mortlake
Per metre for a liner, $500–$900
Domestic sewer across Sydney in 2026. Longer single runs sit at the lower end of it.
A junction or patch repair, $1,500–$4,000
Seals one defect. Right where the rest of the run is sound and the ground is stable.
A whole domestic line, $6,000–$15,000
Length, diameter and how many branches need reinstating are what move the number inside that band.
Digging it up, from $2,500 plus making good
Excavation is only half the cost. Replacing the driveway or garden above it is the other half.

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.
Not Sure If It Needs Relining At All?
Send it through and we will come back with what it is likely to be, what the survey costs, and whether relining is even the right conversation.
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.
Generally it turns on whether the pipework serves your lot alone or more than one. A branch inside your walls feeding only your bathroom is usually yours; the stack it joins and anything in common property usually is not. Settle it before the quote. Relining often makes the conversation easier because it is cheaper than the alternative for a shared line and needs no ceilings opened.
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.
It is groundwater and stormwater entering the sewer through cracks and open joints, and it matters more than most people expect. It quietly overloads a line that would otherwise cope, which shows up as a system that backs up in wet weather and behaves perfectly in dry. If that is your pattern, sealing the run is the fix and clearing will never reproduce it.
Drainage work in NSW is licensed, and work on the sanitary drain is notified to the water authority with a plan of what was done. You should also receive the before and after camera footage. Keep all of it with the property file: on older pipework it is what a conveyancer, insurer or buyer refers to.
