A continuous sleeve through the whole length rather than a patch at the one spot somebody found. No excavation, and footage either side of the work.

Here is the pattern we see repeatedly on established properties. A drain gives trouble. Somebody films it, finds a defect, digs down to that spot, replaces a short length and backfills. It works, and everybody is satisfied.
Two or three years later the same run gives trouble again, a metre or two further along, and the whole exercise repeats. That is not bad luck and it is not bad workmanship. It is what a point repair is.
The pipe either side of the repaired section has been in the ground precisely as long, laid the same way, in the same conditions. It is the same age and it is at the same stage of its life. Fixing the part that failed first does not change anything about the part that will fail second.
A liner works differently. It runs continuously through the entire section, sealing every joint along the way including the ones that had not started leaking yet. That is the difference between repairing this year's defect and retiring the run, and on a line that has already been opened once it is usually the cheaper of the two over any sensible timeframe.
Say so when you ring. A run that has already had one point repair is the strongest case there is for lining the whole length.
A point repair leaves everything either side exactly as it was. The metre that failed gets replaced and the twenty metres around it stay the age they have always been.
That is not a criticism of point repairs. It is simply what they are, and on a genuinely isolated defect it is the right answer.
It matters on a run that has already been opened up once before, which on these streets is common.
A second failure a metre along is the expected outcome rather than bad luck. The same material, the same age, the same ground movement, the same trees.
So the useful question after a point repair is not whether it worked. It is what the rest of the run looks like, and the camera answers that.
Two failures in different places on the same line is the installation reporting its condition rather than a coincidence.
Continuous through the section, including the parts that were still fine. Every joint along the lined length stops being a joint.
That is the difference between fixing a failure and removing the mechanism that produces them. It is also why the design life is measured in decades rather than in seasons.
On a run that has already been dug once, it is frequently the cheaper answer over any sensible time horizon.
A flexible sleeve carrying resin is pulled through the damaged length, then inflated so it presses hard against the existing wall while the resin sets.
What you are left with is a pipe within a pipe: continuous, smooth-walled, a few millimetres narrower, and structural in its own right rather than a surface treatment.
The whole thing happens through an access point that already exists, so the ground and whatever is on top of it stay exactly as they were.
On these blocks the planting is frequently decades old and it is a substantial part of what the property is worth. A trench through it does not recover in a season.
Cutting, excavating, backfilling and reinstating is where an excavation quote goes, and the reinstatement of an established garden is the part that cannot really be priced.
So the honest comparison is liner against pipe plus everything above it, not liner against pipe.
Reaching a drain by trench, on a property where a mature tree sits over the line, means cutting structural roots. That has consequences for the tree that show up over the following seasons.
It may also not be your decision alone. Significant trees are frequently protected, and damaging one is a matter for the council rather than for a contractor on the day.
A liner never breaks the surface, so none of that arises. The drain gets repaired and the tree is not involved.
Relining repairs a pipe that is damaged. It does not rebuild one that is gone, and it does not correct a pipe that is no longer falling the right way.
Anybody offering to line a collapsed section or a length that has dropped out of grade has either not looked at the footage or is hoping you will not ask.
Where it comes up, a short replacement plus lining over the rest is a perfectly normal and sensible result rather than a fallback.
A liner has no way of knowing a junction is there, so it seals over it like any other part of the wall. Reopening it afterwards is a defined step in the job.
It happens once the resin has cured, from inside, and it gets filmed so you can see the result.
A junction left closed announces itself immediately, because the branch behind it stops draining. There is no version of this that stays hidden.
Find out how many metres each is pricing and why. Length is the biggest single variable and it is the one least often stated plainly.
Find out what condition the surface will be in when everybody leaves. A dig quote that finishes at backfill has priced part of a job.
And find out what each thinks is wrong. A liner and an excavation proposed for the same pipe usually mean two different diagnoses, not two approaches to one.
Two video files and a short written report. What the line looked like, what was done to it, and anything worth watching in future.
You get them whatever they show, including on the occasions when the honest finding is that nothing needed doing.
It is worth filing properly. The next person to look at that drain, whoever they turn out to be, then starts from an answer rather than from nothing.
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 genuinely 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.
The whole section, not just the defect, because the argument for lining is about what the rest of the run looks like.
Patch or full length, with the recording behind the recommendation rather than an opinion.
The pipe prepared, the liner installed and cured in place, and any junctions reopened.
So you can see the finished surface end to end, and you keep both recordings.
Get the whole run filmed rather than just the spot. The recommendation usually changes once you can see the rest of it.

That fixes the defect they could see. It does nothing about the rest of a run that has been in the ground exactly as long and is exactly as old.
It treats a length rather than a point. The sleeve runs continuously through the whole section, sealing everything along the way including the joints that were not yet leaking. It is the difference between repairing a defect and retiring a run.
The material is rated at around fifty years. Practically, the useful part is that there is no joint left anywhere along the lined length for anything to enter through.
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 length replaced instead. The footage tells us which of those you have before you commit.
Most residential jobs finish inside a day with the line back in service the same afternoon. A long or awkward run can go into a second.
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 and whether this run has been opened before. That second answer usually decides between a patch and a length.
Sealed continuously from the inside, with nothing above the pipe disturbed.
