The defect repaired from inside the existing pipe, so the path, the planting and the frontage stay exactly as they are.

Relining pulls a resin sleeve through the existing pipe and cures it hard. The defect is sealed and the joint that had opened is bridged, and what is left has no entry point for the next root.
The reason it earns its keep on an established property is what sits on top of the pipe. A front path, mature planting, a tiled verandah, a driveway laid before anybody thought about drains. Those things are part of what the house is, and they are not line items that get put back the way they were.
Reinstatement is where excavation quotes get vague. Digging a trench is a known cost. Restoring what was over it to a standard the owner is happy with is not, and it is very frequently the larger number of the two.
So it is worth asking any excavation quote a simple question: what is the reinstatement figure, and what standard is it to. A liner makes that question unnecessary, because nothing on the surface is touched.


Ask what the reinstatement figure is and to what standard. That answer is frequently the whole comparison.
Digging a trench is a known cost. Putting the surface back is not.
On an established frontage it is very often the larger of the two.
Paths, planting, verandahs and driveways are part of what the property is.
A liner leaves every bit of that where it stands.
They do not break sound pipe. They find an opening that has already moved.
Sealing the run continuously removes the entry rather than this year's roots.
A pipe that has lost its shape or its grade needs that length replaced.
We say so off the footage rather than midway through the work.
Footage before, footage after, and a written account of what was done.
Worth filing with the property papers.
Fixed price agreed before anything starts. These are indicative 2026 ranges.
Deducted from the job if you proceed, and the footage is yours either way.
Where one short length is the whole problem.
Priced on length and access rather than by the hour.
Reopened from inside once the liner has cured.
Where a collapse makes a liner the wrong answer.

Not just the defect. Length and bends decide whether a liner is even the right method here.

A figure built on what the camera showed, with the recording behind it rather than a description of it.

The pipe prepared, the liner installed and cured in place, and any junctions reopened.

So you can see the finished surface yourself, and the garden looks exactly as it did when we arrived.
Get it filmed before anybody breaks ground. It regularly changes both the method and the number.

A resin sleeve is drawn through the pipe you already have and cured hard in place, using the old pipe as a mould. The fault is sealed and the joint that had opened is bridged, leaving a continuous surface with nowhere for a root to get back in.
Because of what sits above the pipe. On an established property the frontage, the path, the planting and sometimes a tiled verandah are part of what the house is. A trench takes all of that out and reinstatement rarely matches. A liner leaves the surface untouched entirely.
The material is rated at around fifty years. More usefully, there is no joint left at the point that failed, so the thing that caused the problem is gone rather than repaired.
By a couple of millimetres, and it rarely matters. The new inner surface is smoother than the original, so flow generally ends up the same or better.
No. A pipe that has collapsed, lost its shape, or dropped out of grade needs that section replaced. The footage shows which of those you have before you commit to a method.
Most residential jobs finish inside a day with the line usable the same afternoon. A long or awkward run can run into a second day.
A patch over a single defect is $1,500 to $2,500. A full section is $4,000 to $9,000 depending on length and access. The camera inspection first is $250 to $450 and comes off the job if you proceed.
Tell us what the camera found, or ask us to put one down first. And tell us what sits above the run, because that is half the comparison.
Sealed from the inside, with everything on the surface left where it is.
