| Spot repair (short section) | $800 to $1,800 | A single localised defect |

| CCTV inspection before quoting | $200 to $350 | Every relining job, no exceptions |
What does pipe relining actually involve?
Relining installs a new structural pipe inside your old one without digging, by inverting or pulling a resin-saturated liner through the drain and curing it in place. The cured liner becomes a smooth, jointless pipe within the old host pipe, sealing the cracks and joints that roots were entering through. Because there are no joints, there is nothing for roots to attack next season. The whole process runs from existing access points, an inspection opening or a small entry pit, which is why your driveway, slab and gardens stay untouched. A typical residential reline is done in a day, and the drain is back in service the same night.
Why is relining priced per metre and what moves the price?
Per-metre pricing reflects the liner and resin consumed, and the price moves with pipe diameter, access and how much preparation the line needs. The $400 to $600 or more per metre range covers standard residential sewer diameters. Larger pipes need more material. Junctions need lateral connections cut and sealed, heavy root infestations need thorough jetting and cutting before the liner goes in, and awkward access adds setup time. This is why nobody honest quotes relining sight unseen. We put a camera down first, measure the line, map the defects, and then give you a fixed price for the job, not a per-metre estimate that grows on invoice day.
Is relining cheaper than digging up and replacing the pipe?
Under hard surfaces, almost always; in open lawn, not necessarily. Full excavation and replacement runs $5,000 to $15,000 plus, and the "plus" is doing the heavy lifting when the pipe runs under a slab, a driveway, a pool surround or a retaining wall, because you pay to break and reinstate everything above the pipe. That is where relining at $400 to $600 or more per metre routinely comes in far cheaper for the same result. But if a short, shallow run through open lawn has failed, digging and laying new PVC can genuinely be the cheaper fix, and we will tell you so. In our experience the worst value option is repeatedly paying $250 to $400 for machine clears on a drain that has a permanent defect.
When is a spot repair enough instead of a full reline?
A spot repair at $800 to $1,800 is the right call when the camera shows one localised defect in an otherwise healthy pipe. A single cracked section, one displaced joint or one root entry point does not justify relining the whole run. A short patch liner over the defect fixes the problem for a fraction of the cost. Where spot repairs go wrong is when they are sold for pipes with defects every few metres, and you end up buying three patches over two years instead of one reline. The CCTV footage makes this decision honest: you see the whole pipe, we price both options, and the pipe's actual condition picks the winner.
How long does pipe relining last?
Quality liners are designed for a service life of 50 years, and manufacturers back them with long warranties. The cured liner is a structural pipe in its own right, resistant to root intrusion because it has no joints, and smoother inside than the old clay it replaced, so flow actually improves. Longevity depends on proper installation: thorough cleaning and root cutting first, correct resin cure, and a post-installation camera pass to prove the finished result. We give you the before and after footage with the invoice, which is also handy evidence at sale time that the sewer has been permanently repaired rather than patched.
Does relining need council approval in Queensland?
Relining is drainage work under the Plumbing and Drainage Act 2018 and must be done by a licensed drainer, with any required notifications handled by the plumber. Repairs to existing sanitary drainage are generally handled within the licensed plumber's certification obligations rather than needing you to lodge anything yourself, and where connection-point work touches the council's assets, coordination with the local water utility is our job, not yours. The practical takeaway for owners is simple: use a licensed operator, get the CCTV proof before and after, and keep the paperwork. The QBCC licence register lets you check anyone who quotes you.
