Aimed at the point where later work was cut into the original line, because on this housing that is where the trouble tends to be rather than along the run.

On a lot of properties the relining conversation is about a length of pipe that has had enough. Here it usually is not, because the original drainage was laid in one program and it is consistent.
What is not consistent is what was cut into it later. A rear extension, a second bathroom, a laundry moved out into a new part of the house. In each case a new waste had to join the existing line, and how well that junction was formed is entirely down to whoever did it and how much they cared.
A badly formed junction leaves an edge, a lip, or a piece of the new pipe protruding into the old one. Every one of those collects. Material stalls at that point and builds from there, and the pipe either side can be in perfect condition while the same fixture blocks every winter.
The repair follows the diagnosis. The section is lined and the junction reinstated, cut back open from inside once the liner has cured, which leaves a clean entry where an obstruction used to be. Sometimes the junction can be dealt with more directly, and where a section has genuinely collapsed it needs replacing. The footage decides which, which is why we will not quote without it.
If that fixture came with an extension, the junction is the first place to look and the camera settles it.
Laid in one program, to one set of practices, with the materials of that period. On housing developed in a single wave, the main run from the house to the boundary is generally the best part of the system.
That is unusual and it is worth knowing, because it means the standard advice about aged drainage does not describe this suburb particularly well.
It also means that when something does go wrong, the odds favour a specific location rather than a whole line at the end of its life.
An extension, a second bathroom or a granny flat meant a new waste joining an existing line, cut in years later by somebody else, to whatever standard applied at the time.
Those junctions are where the defects are on this housing. Not the length of pipe, the point where somebody made a connection into it.
Which is why it matters that you tell us the property has been added to. It points the camera at the right ten metres instead of the whole run.
A lip at a junction, a section of pipe intruding into the run, or a badly cut entry stalls whatever comes past it. Paper catches, fat cools onto it, and a blockage builds outward from that point.
It gives the same symptom as a root or an object, which is why it gets cleared repeatedly rather than fixed. Each clearance works, and then it happens again.
On camera it is obvious in seconds. That is the difference between a diagnosis and a guess.
A junction problem is a short, specific repair rather than a long one. The affected section gets lined and the junction gets reinstated, which is very different work to relining a whole run.
It also means the price is different, and usually smaller. A quote for lining an entire line when the defect is one junction is a quote for the wrong job.
So it is worth asking any quote how many metres it covers and why that length. The answer should come from the footage.
The section gets lined, then the junction is cut back open from the inside once the resin has cured. That is ordinary practice rather than a complication.
It gets confirmed on camera afterwards, which is the point of the after footage. A junction left covered would stop the branch it serves from draining, and that would be obvious immediately.
The finished result is a continuous smooth bore through the section that was causing the trouble, with the connection reopened cleanly.
A resin-saturated liner is drawn into the existing pipe, inflated against the inside wall and cured in place, forming a new pipe inside the old one. Slightly smaller in bore, continuous, and with no joints.
It is not a coating or a patch. The cured liner is structural in its own right, which is why it carries a design life measured in decades.
Nothing above the pipe gets opened, which on a landscaped block is most of the attraction.
No liner rescues a pipe that has lost its shape or its grade. A crushed length, or a section that has settled so water no longer runs downhill through it, has to come out.
Grade is the one people miss. A pipe can be perfectly intact and still fail because it no longer falls the right way, and there is no lining solution to that.
A short open replacement plus a liner over the rest is a common and sensible outcome, and on this housing it is usually short.
Before and after, plus a written account of what was found and what was done. Yours to keep whatever it shows.
Worth filing with the property papers, particularly on a property that has been extended. It is the record of what the drainage under the addition actually looks like.
The next person to look at that line, whether that is us in five years or somebody else entirely, starts from an answer rather than from scratch.
The liner rarely drives the price of an excavation. Cutting the surface, getting plant to the pipe, excavating, backfilling and reinstating is where the money in a dig quote actually sits.
On established blocks with mature gardens and paving, the reinstatement is the part that does not come back looking the way it did. A trench through a lawn recovers. A trench through a driveway does not.
So the honest comparison is liner against pipe plus everything above it, not liner against pipe.
Ask both for the length in metres and get it in writing. Two quotes that look far apart are frequently describing different amounts of work.
Then ask what each includes for putting the surface back. On a landscaped block that line item can be larger than the drainage work itself.
Then ask what the footage shows. If the two quotes disagree about the method, they usually disagree about the diagnosis, and the recording is the only thing that settles that.
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.
Cut back open from inside once the liner has cured, leaving a clean entry.
Priced on length and access rather than by the hour.
Where a collapse makes a liner the wrong answer.
Which fixture, how often, and whether it came with later work. That tells us where to point the camera.
End to end, but with particular attention to wherever something joined the original line.
The section lined, cured in place, and the junction cut back open from inside to leave a clean entry.
So you can see the junction as it is now rather than take our word for it, and you keep both recordings.
Get it filmed first. On this housing the answer is frequently a junction rather than a length, and that is a different job.
Call 1300 381 569Because that is where the defects on this housing tend to be. The original drainage was laid in one program and it is consistent. What is not consistent is what got cut into it afterwards, when a rear extension or a second bathroom was added and a new waste had to join the existing line.
A badly formed one leaves an edge, a lip or an intrusion where the new pipe enters. Every edge collects. So the line either side can be in perfect condition and the same fixture will still block, because material stalls at that one point and builds from there.
The pattern gives it away. The same fixture, repeatedly, on a house that has been added to. If a camera then shows sound pipe with one badly formed junction in it, that is the whole explanation.
It can. The section is lined and the junction is then reinstated, which is cut back open from inside once the liner has cured. Done properly it leaves a clean entry rather than the obstruction that was there.
No. Sometimes the junction can be repaired more directly, and where a section has collapsed or dropped out of grade it needs replacing instead. The footage decides that, which is why we will not quote without it.
The material is rated at around fifty years, and the repair is continuous, so there is no joint left at the point that failed.
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. Reinstating a junction is $400 to $900. The camera inspection is $250 to $450 and comes off the job.
Tell us which fixture is the problem and whether it came with an extension or a second bathroom. That connection is the one worth making before anybody quotes.
Filmed, lined where lining is right, and the junction reinstated properly.
