Length of the damaged run
The single biggest factor. Lining four metres and lining twenty-four metres are different jobs, and the camera is what tells us which one you have.

Nobody can give you a number down the phone, and anyone who does is going to revise it. Here is what the price is actually made of, so you can read a quote properly — ours or anyone else’s.
The single biggest factor. Lining four metres and lining twenty-four metres are different jobs, and the camera is what tells us which one you have.
We line from 50mm to 300mm. Larger bore means more liner, more resin and more equipment on site.
A shallow line with an open inspection shaft in the front yard is quick. Three metres down behind a locked side gate is not.
Every branch connection has to be reopened with a robotic cutter after the resin cures. Four junctions is meaningfully more work than none.
A line packed with roots and scale needs serious jetting before anything can bond to it. That prep is where cheap quotes quietly cut corners.
Terracotta, PVC, concrete and cast iron all line, but a badly deformed or offset section may need extra work or may not be linable at all.
Compare two quotes for the same broken sewer under a driveway. The excavation quote covers the plumbing. It usually does not cover cutting and removing the concrete, re-pouring it, matching the finish, replacing the garden bed the machine drove over, or the days you cannot park there.
Relining has none of that, because nothing is opened. That is the gap people miss when they compare the two numbers side by side.
| Criterion | Pipe relining | Dig and replace |
|---|---|---|
| Time on site | 1–2 days | 3–5 days, often longer |
| Your driveway | Untouched | Cut, removed, re-poured |
| Garden and paving | Untouched | Excavated and reinstated |
| Root re-entry | Sealed permanently | Returns at the new joints |
| Reinstatement cost | None | Concreting, paving, landscaping |
| Council permits | Rarely needed | Often needed for crossings |
| Warranty | 50 years on the liner | Workmanship only |
Honest caveat: if a pipe has fully collapsed there is nothing left to line against, and we will tell you to dig. The camera decides, not the quote.
The full breakdown is in pipe relining versus pipe replacement.
If a quote is missing three of those, it is not a quote, it is an opening position.
“Excellent job clearing and fixing the tree roots blocking our sewer pipe. Straight answers, no upsell, and the driveway never got touched.”
“We had four plumbers come out. Nick was the only one who actually found the problem instead of guessing, and the camera footage proved it.”
“Nick has been maintaining and clearing our sewer pipes from tree roots for years. Customer service is 10/10 and the relining finally ended it.”

Published averages are close to meaningless because the variables swing the number so hard. A short four-metre patch on a shallow, accessible line is a very different job from a twenty-five metre run three metres down with four junctions to reinstate. What we can promise is that the inspection that produces your number is free, and the number does not move once you have accepted it.
On the plumbing alone the two are often comparable. Relining wins once you add what excavation actually costs you — cutting and re-pouring a driveway, replacing paving, reinstating a garden, possible permits, and three to five days instead of one or two. On a driveway or slab job it is rarely close.
Because an honest number needs four facts nobody has until a camera has been down the line: how long the damaged run is, what diameter it is, how deep it sits, and how many junctions come off it. A phone quote is a hook that gets revised upward on the day.
Yes. The inspection is free when it forms part of a relining or repair quote, and you keep the footage whether or not you book the work. Standalone surveys, such as a pre-purchase inspection, are a flat fee we tell you on the phone.
Junctions take extra work — each one is reopened with a robotic cutter after the resin cures — so they are counted in the quote. Bends generally are not charged separately. Either way they are in the fixed price before you agree to anything.
For larger jobs, body corporate work and multi-run properties we stage the work and the invoicing by run. For a standard residential job it is one price, invoiced on completion.
Most policies exclude gradual deterioration, which is what an aged clay line is. Sudden damage is a different conversation and the footage and report we supply is exactly what an assessor asks for. Beyond your boundary the line belongs to the water authority, and our inspection shows which side of it your problem sits on.
Not automatically, but ask two questions: does it include jetting the line properly before lining, and does it include reinstating every junction. Those are the two steps that get left out to make a number look good, and both cost far more to fix afterwards.
Tell us what the drain is doing and we will book a CCTV inspection, usually same day. No charge, no obligation, and you keep the footage either way.
