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 Pipe
Relining In
Killara
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.

What Relining Actually Is In Killara
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.
Repairing the drain without touching the fabric
Many grand Federation homes still run original earthenware drains that crack and shift with age, letting roots and debris in.
On a period property the drainage repair is rarely the expensive part. Tessellated verandah tiles, original brick paving, a mature garden or a heritage-listed frontage all cost far more to reinstate than the pipe underneath costs to fix.
That is the argument for trenchless in one sentence. The liner is drawn through an existing opening and cured in place, so the surface above is never disturbed and there is nothing to match, replace or explain to council.
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.
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.
Killara sits in leafy Ku-ring-gai on Sydney’s Upper North Shore (postcode 2071), a heritage suburb of grand Federation homes on large blocks between Lindfield and Gordon on the North Shore rail line. With mature trees lining nearly every street and older clay pipework beneath them, local drains see plenty, and we know the ground here well.
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.
Stormwater lines are relinable too
Killara’s elevated, sloping garden blocks send heavy-rain runoff surging through stormwater pits that choke on leaf litter and back up.
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.
Steep blocks are where no-dig earns its money
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.
What it costs in Killara
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.

From Survey To Finished Liner
Step 01
Step 01
Survey And Measure
We find the fault, measure it from an access point, and check the fall is intact. That last check is what stops a liner being installed into a belly.
Step 02
Quote In Writing
Per metre, with access and junction reinstatement itemised, and the excavation comparison alongside it so you can see both.
Step 03
Reline It
Clean, install, cure. One access point, one day for most homes, and no trench across the property.
Step 04
Hand It Over Documented
Branches reopened, final footage, certificate and notification. Keep it with the property file, it is worth real money at sale.

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.
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, 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.
Only if the cause is a defect rather than the gradient. On a steep run, waste can outrun the water carrying it and settle at the first flat section, producing a blockage at the same point regardless of the household. A liner seals the pipe but keeps its shape, so if the profile is wrong the pooling continues. The camera run distinguishes the two.
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.
Both. Stormwater suffers the same failures and relines the same way: cracked lengths, open joints, root intrusion and sections that silt because the fall has flattened. On a property that floods in every heavy downpour, a defective line is frequently the reason rather than the rainfall.
