Repaired from inside the pipe, which on a line running under a row of properties is the difference between one job and a negotiation with everybody in the street.

Everywhere in Sydney, relining is the tidier option because nothing gets excavated. On a shared line running under a row of terraces it stops being about tidiness and becomes about whether the job is possible at a sensible price at all.
Think about what excavating a shared line actually requires. The run goes under more than one property, so it means access across more than one boundary. It means more than one owner agreeing to it, on the same dates. It means more than one surface opened and reinstated, and reinstatement is where excavation quotes go quiet in any case.
A liner needs none of that. The work happens inside the pipe through an existing access point, and every property on that section is repaired by the same sleeve on the same day.
That last part is worth stating plainly, because it is the argument that actually persuades a row of neighbours. Lining a shared section once repairs it for everyone it serves. The alternative is each owner dealing with their own portion of the same tired pipe over the following five years, at four separate call-outs, for more money in total.
Then get it filmed once, together. One inspection answers it for the whole row and costs what one inspection costs.
More than one boundary, more than one owner agreeing, more than one surface reinstated, and frequently access through somebody else's property to get to the pipe.
Any one of those can stall a job. Together they turn a straightforward repair into a project with several people's diaries in it.
That is before anybody has argued about the cost.
The work happens inside the pipe from an existing access point. Nothing above it is opened, no boundary is crossed at the surface, and nothing has to be put back.
So the number of people who have to agree drops to the number who have to pay, which is a materially easier conversation.
On a shared line that practical difference is frequently worth more than the difference in price.
Resin-impregnated liner in, inflate against the host pipe, let it cure, trim and inspect. The old pipe stops carrying water and becomes the mould the new one was shaped in.
The result is a continuous length with no joints and a smoother bore than the pipe it replaced, at the cost of a few millimetres of diameter.
Nothing gets excavated. It is done from an existing opening, which is the entire reason it is worth talking about.
Every property that line serves is repaired on the same day, in one visit, with one lot of equipment on site.
That is a genuinely different proposition from a point repair, which fixes one defect and leaves the rest of a jointed line exactly as old as it was.
On a shared run it also means one conversation about cost rather than a recurring one every time a different property notices.
Lines of this age were laid in short sections with a joint every metre, and each of those is somewhere the ground can move a fraction and open a gap.
That gap is what roots find. They do not break sound pipe, they enter at an opening that was already there.
A cured liner removes every joint along the section it covers, for every property that section serves.
One repair, quoted once, for a defect that affects several owners. How that gets divided is for the owners rather than for us, and we will not take a view on it.
What we can do is quote it once, clearly, with the length in metres and what is included, so everybody is looking at the same document.
Ambiguity about the number is what makes these conversations difficult, and a clear quote removes most of it.
No liner rescues a pipe that has lost its shape or its grade. A crushed section, or one that has settled so water no longer runs downhill through it, has to come out.
On a shared line that is the scenario worth knowing about early, because it is the one that brings the boundaries and the agreements back into it.
A short open replacement plus a liner over the remainder is a common outcome and it keeps the digging to one place.
Where each property joins the shared run, the liner covers the opening and it is cut back open from inside once cured. Ordinary practice, confirmed on camera afterwards.
On a shared line there are more junctions than usual, one for each property, so the after footage matters more than it does on a private run.
A missed junction would stop that property draining, which is immediately obvious rather than hidden.
Narrow frontages, rear lanes and courtyards that have been paved or built over all affect how equipment reaches the line.
It is worth establishing before a date is agreed rather than on the morning, particularly where the access point is in somebody else's courtyard.
That is another argument for the survey coming first. It answers the access question at the same time as the defect question.
Before and after, plus a written account of what was done. On a shared line that goes to every owner rather than to whoever happened to ring us.
It is the only durable record of what the shared asset actually looks like, and it is worth each owner filing with their own property papers.
The next time anything happens on that line, whoever notices it starts from an answer instead of from scratch.
Fixed price agreed before anything starts. These are indicative 2026 ranges.
One inspection answers it for the whole section, and it comes off the job.
Where one short length is genuinely the whole problem.
Priced on length and access, and repairing every property the section serves.
Reopened from inside once the liner has cured.
Where a collapse makes a liner the wrong answer.
The whole section, plus which properties join it, because on this housing that decides who the job actually belongs to.
A single figure for the section, clear enough for a row of neighbours to look at together and decide.
The pipe prepared, the liner installed and cured in place, and any junctions reopened.
So every owner can see the finished surface, and nothing above ground on anybody's property has been touched.
Ask whose land the trench crosses and who has agreed to it. Then get it filmed before anybody breaks ground.
Call 1300 381 569A resin sleeve is drawn through the pipe you already have and cured hard in place, using the old pipe as the mould. The defect is sealed, any joint that had opened is bridged, and what is left is continuous with no entry point. Nothing is excavated.
Because a shared line is exactly the pipe you least want to dig up. It runs under a row of properties rather than one, so excavating it means access across more than one boundary, more than one owner agreeing, and more than one surface put back. A liner sidesteps every part of that.
One. That is the point worth understanding. A shared section lined once is repaired for every property it serves, so it is a single job at a single price rather than each owner solving their own portion of the same pipe over the following five years.
That is between the owners, and we will not give a legal opinion on how it should be split. What we can do is quote the job clearly enough that a group of neighbours can look at one figure and one piece of footage and make their own decision.
The material is rated at around fifty years, and the repair is continuous, so there is no joint left at the point that failed.
No. A pipe that has collapsed, lost its shape or dropped out of grade needs that section replaced, and under a row of terraces that is a serious job. The footage settles which of those you have before anybody commits.
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 the line serves more than one property. That second answer changes the whole shape of the job.
Sealed from the inside, once, for every property that section serves.
