The defect sealed from inside the pipe, with the equipment carried in through the side gate rather than a machine brought into the yard.

The two options for a failed drain get compared as though the difference is the repair itself. On a lot of properties around here the difference is something else entirely: getting the equipment to the work.
Relining gear is carried in. It comes through a normal side gate, on foot, and it sets up at an access point. That is the whole logistical requirement.
Excavation needs plant, and plant has to get to where the pipe runs. On an established property with a rear yard, that can mean a route that does not exist without taking something apart, or it can mean hand excavation instead, which is slow and priced accordingly.
Neither of those appears in a headline excavation figure, and both are real money. So it is worth asking any quote a direct question: how is the machine getting to the pipe, and what happens to what is in its way. The answer is frequently the whole comparison.


Ask how the machine reaches the pipe and what happens to whatever is in the way. That answer is frequently the whole comparison.
Relining gear is carried in. Excavation plant has to be driven in.
On an established property those are very different propositions.
Where plant genuinely cannot reach, that is the alternative.
It rarely appears in a headline figure and it is always real money.
No joint left at the point that failed, and nothing for anything to enter through.
Roughly a fifty year design life on the material.
A pipe that has lost its shape or its grade needs that length replaced.
Which on a property with limited access is exactly the job you want to know about early.
Before and after, plus 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 genuinely 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, and priced with the access included.

So we can tell you where the run goes and, just as usefully, what would have to happen for a machine to reach it.

Liner against excavation, with the access to the work included in the excavation figure rather than left off it.

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

So you can see the finished surface, and the yard looks exactly as it did when we arrived.
Get it filmed and located before anybody quotes machinery. Where the pipe runs decides more than what is wrong with it.

Frequently it is not the pipe repair that separates them, it is getting the machinery to the work. Relining equipment comes in through a normal gate on foot. Excavation needs plant, and on an established property with a rear yard, getting plant to where the pipe is can be a larger exercise than the repair it enables.
Then digging is either hand excavation, which is slow and expensive, or it involves taking something apart to make room. Neither of those appears in a headline excavation figure and both are genuine costs. It is worth asking any excavation quote how the machine is getting to the pipe.
A resin sleeve is drawn through the existing pipe and cured hard in place, using the old pipe as a mould. The defect is sealed, any joint that had opened is bridged, and what is left is continuous with no entry point.
The material is rated at around fifty years, and the repair is continuous, so there is no joint left at the point that failed.
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, and on a property where plant cannot easily reach it, that is a serious job. The footage settles it before you commit.
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 is $250 to $450 and comes off the job if you proceed.
Tell us what the camera found if anybody has looked, and whether a machine could physically get to where the pipe runs. That second answer shapes the comparison.
Sealed from the inside, with nothing driven into the yard to do it.
