Camera inspection: $300–$750
The first and non-negotiable step. Most operators credit it against the works if you proceed.
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.
A resin-saturated liner is drawn into the existing pipe through an access point, inflated so it presses against the wall, and cured until it hardens. What you are left with is a continuous pipe inside the old one, with no joints along its length and a slightly smaller bore than the original.
Nothing is excavated, and the cured surface is smoother than the clay or concrete it lines, so flow is typically maintained or improved despite the small loss of diameter. On a property where a driveway, mature garden or paving sits over the line, that is the whole argument.
Street trees planted when Dean Park was new are now mature, and their roots find the glued PVC joints and inspection openings of the original pipework.
Cutting roots out clears the pipe and does nothing about the way in. The joint they came through is still open, the tree is still looking for water, and the interval before the next blockage is set by how fast it grows back. That is why a jetted line often reblocks on a schedule you could almost diary.
A liner seals the full run, joints included, so there is no opening left to find. It is the one intervention that changes the pattern instead of resetting the clock.
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.
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.
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.
It is not a universal fix and anyone presenting it as one is selling rather than advising. A liner follows the shape of the host pipe, so it cannot correct a run that has lost its fall or sagged into a belly. A collapsed section has nothing to line against. A pipe crushed badly out of round has to be replaced.
In those cases the right answer is excavation, and we would rather quote that and be trusted than reline something that will disappoint you in two years.
Drainage work in NSW is licensed work, and work on the sanitary drain is notified to the water authority with a plan showing what was done. That is not a formality: it is what the next owner, conveyancer or insurer refers to.
You should receive the paperwork without asking. If a quote is materially cheaper than the others, it is worth confirming that notification and compliance are included in it.
Manufacturers generally rate cured-in-place liners at around fifty years, which is comparable to a new pipe and considerably longer than the remaining life of the earthenware most of them are installed into.
The practical test is different from the marketing one: a liner has no joints along its length, and joints are what fail. Removing them is the reason the number is that high.

Domestic sewer across Sydney in 2026. Longer single runs sit at the lower end of it.
Seals one defect. Right where the rest of the run is sound and the ground is stable.
Length, diameter and how many branches need reinstating are what move the number inside that band.
Excavation is only half the cost. Replacing the driveway or garden above it is the other half.
