There is no price on this page, and there is a reason for that. Instead: every variable that moves the number, and how the quote is built once a camera has been down your line.
Search for what relining costs and you get ranges: national averages, or per metre rates off an aggregator, none of them measured against the pipe under your property. A per metre rate is close to the least useful number in this trade anyway, because the metres are the part of the job that varies least.
Until a camera has been down the line, nobody knows how long the damaged section is, where it starts, how many junctions sit inside it, how much root mass has to come out before resin will bond, or whether the pipe holds its shape well enough to line at all. Quoting before you know that means padding for the worst case, or quoting the best and revising on the day. Both are worse for you than waiting for the footage.
So we do not publish a price and will not guess one on the phone. We put a camera down, then the scope and the price in writing, in that order.
What the camera is actually measuring
Six variables on one drawing: how far the damage sits from the access point, how long the damaged run is, the diameter, the depth, the junctions inside it, and the surface above.
What actually changes the price
Does run length matter most?
It is the single biggest variable, but it is the length of the damaged section that counts, not the length of pipe on your property. A liner has to cover the fault plus enough sound pipe either side to seal against, so a failure in the middle of a long run costs what that section costs, not what the whole line would. Liner and resin are consumed by the metre, and so is cure time, which is why this one moves the number more than anything else on the list.
Why does diameter change it?
A wider pipe needs a wider liner, and resin volume grows with the circumference and the wall thickness together, not with the diameter alone. Larger bores also need heavier gear to install and inflate the liner, and they take longer to cure because there is more material to cure. A short run in a large diameter line can cost more than a longer run in a small one.
Why does access matter?
Because relining is done from the ends, not from above. Where there is a usable inspection opening near the damage, the liner goes in through it and nothing is disturbed. Where the nearest opening is a long way from the fault, more liner is used reaching it and more cleaning is needed along the way. Where there is no usable opening at all, one has to be created, and that is the only part of a reline that involves digging. Vehicle access counts too: the jetter, the reel and the curing gear have to get within working distance of that opening.
Does pipe depth change anything?
Indirectly, and it can be significant. Depth does not change how much liner the pipe needs, but it changes the work around the entry point. A shallow line is straightforward to open up if an entry has to be made. A deep one in sandy Perth soil may need the excavation shored, which is a real cost and a real safety requirement, and it is one of the things the inspection measures for.
What do bends and junctions add?
Work at both ends of the job. A liner has to be drawn through every bend on the run and pressed out evenly against the wall around it, which takes longer and narrows which liner and curing method suit the job. Junctions are more involved again: a cured liner seals over the branch connections it passes, so each one has to be cut back open and finished after curing, or that fixture stops draining. A run with several junctions inside the damaged length is a different job to a straight run of the same metreage.
Does root damage severity matter?
Yes, and this is the variable people least expect. Resin bonds to a clean pipe wall, so everything in the way has to come out first. A few fine roots at one joint is a straightforward clean. A packed root mass through several joints needs cutting, then jetting, sometimes in more than one pass, and the camera has to go back down to confirm the wall is genuinely clear before a liner is committed. Heavy root intrusion also tends to mean the joints behind it have opened up, which changes how much of the run needs covering.
Is reinstatement included?
Usually there is nothing to reinstate, and that is most of the reason relining compares well on cost. Nothing above the pipe is lifted, so there is no trench to backfill, no paving to relay and no lawn to replace. Where an entry point genuinely has to be created, making that one opening good again is scoped and priced as its own line on the quote, and you see it before you agree to anything. It is never absorbed quietly or discovered afterwards.
Is a CCTV inspection needed first?
Yes, on every job, without exception. Every variable on this page is something a camera measures and nothing else can: where the damage starts, how far it runs, what the pipe is made of, how many junctions sit inside the damaged length, how much material has to be cleared, and whether the pipe still holds its shape well enough to line at all. The inspection is a job in its own right, and what it involves and what it costs are confirmed with you in writing before anyone is booked in.
Is relining cheaper than replacing?
They are not two prices for the same work. Replacement buys new pipe plus a bill for everything destroyed to reach it: excavation, spoil, backfill, compaction, then the concreting, paving or landscaping that puts the surface back. Relining buys a new pipe wall and almost none of that, against one requirement and one condition, which are somewhere to introduce the liner and a host pipe that still holds its shape. The gap is widest on the kind of block Fremantle is full of, with a limestone wall, a mature garden and original floors sitting over the line, because there the reinstatement is the expensive half of a replacement. On a bare block with a long straight run and nothing above it worth protecting, the gap narrows.
Is a point repair cheaper?
Normally yes, because it uses a short liner, less resin and less cure time. It also only applies to one situation: a single short defect with sound pipe either side of it. Where a run has several failures spread along it, patching each one separately can cost more than lining the length in one pass, and it leaves the joints between the patches exactly as they were. The footage decides which of those you are looking at, not a preference.
How your quote gets made
1
CCTV inspection
A camera runs the line from an existing access point, and you see the same footage we work from.
2
A written scope
What is relined, from where to where, which junctions are reinstated, and anything that has to happen first.
3
A price against that scope
Priced on the run we measured. If the job changes, you approve a revised scope rather than meet it on the invoice.
