Pipe relining cost on the Gold Coast comes down to one thing more than any other, the length of damaged drain that needs lining. The headline rate is roughly $400-600+ per metre installed, but the per-metre figure on its own is misleading because a relining job is never just the liner. There is a camera survey to map the damage, jetting to clean the pipe before lining, the resin and liner material itself, the cure, and the robotic reinstatement of any branch connections. Once you stack all that up, a typical residential relining job on the Coast lands somewhere in the low-to-mid thousands. The only way to get a real number is to put a camera down the drain first.
The honest cost ranges
These are realistic 2026 Gold Coast ballparks, not fixed prices. Treat them as a guide to budget around, then get a quote.
- Per-metre rate: roughly $400-600+ per linear metre installed, depending on diameter, access and how many junctions need reinstating.
- Short isolated section (3-4 metres): roughly $1,500-2,500.
- Mid-length run (8-12 metres, e.g. under a driveway or path): roughly $4,000-8,000.
- Long or complex run with multiple junctions: can push past $8,000-12,000+.
- CCTV camera survey: roughly $200-350 if charged separately, often bundled into the relining quote or credited if you go ahead.
If a number outside these ranges gets quoted, that is not automatically wrong, deep drains, awkward access and unusual diameters all move the price. But it is worth asking the plumber to walk you through why.
What actually drives the price
Length of the damaged section
This is the biggest single factor. You only line the section that is failing, not the whole drain. A single cracked joint with root intrusion might only need 2-3 metres lined. A drain that is cracked along its length needs the full run done. The camera survey is what tells us the difference, which is why we will not quote relining sincerely over the phone.
Pipe diameter
A standard 100mm sewer line is cheaper to line per metre than a larger 150mm main. Bigger diameter means more liner, more resin and a bigger cure.
Access
Relining is sold as no-dig, and for the main run it is. But the liner still has to enter the drain through an access point. If there is a good existing inspection opening at the right spot, that is straightforward. If we have to create an access point, that adds a small excavation cost at one end. Drains buried deep, or running under a slab with no nearby access, cost more to set up.
Junctions and branch connections
Where a branch drain (from a toilet, a gully, a second bathroom) joins the line being relined, the liner seals over that opening and it has to be cut back open with a robotic cutter so the branch keeps flowing. Each junction reinstatement is fiddly skilled work and adds to the cost. A straight run with no junctions is the cheapest case.
Bends
The liner has to navigate the bends in your drain. Gentle sweeps are fine. Tight or multiple bends are harder and occasionally rule out relining for that section.
What is included in a relining quote
A proper relining quote should cover the lot, so you can compare like for like:
- CCTV camera survey and locate (or a credit for one already done)
- High-pressure jetting to clean and prep the drain before lining
- Root cutting where roots are present, often with a robotic cutter at junctions
- The liner, resin and the cure (UV, hot water or ambient depending on the system)
- Robotic reinstatement of every branch connection
- A final post-line camera inspection so you can see the finished pipe
- Footage handed over and a written report
If a quote is suspiciously cheap, check what is missing. Sometimes the cheap number is the liner only, with the camera, jetting and junction work billed on top later.
Why relining can be cheaper than it looks
The sticker price on relining gives people a fright until they price the alternative. Digging up a drain that runs under a concrete driveway, a paved courtyard, established gardens or a slab is expensive and disruptive, and you still have to reinstate the surface afterwards. That reinstatement, new concrete, re-laid pavers, re-turfed lawn, often costs as much as the pipe repair. Relining skips nearly all of it. For drains under hard surfaces, relining is frequently the cheaper total once you count the make-good. We break down both options in our relining vs replacement answer.
Relining vs repeated clearing, the real comparison
If your drain blocks every six to eighteen months because of roots at a cracked joint, you are already paying for it, just in instalments. Drain clearing by jetter runs roughly $200-450+ each time. Four clearances over five years is real money, and the problem is still there. Relining seals the cracks the roots were entering through, so the recurring blockage stops. A jointless relined pipe is root-proof at the lined section. We go through the recurring-blockage math in detail in why your drain keeps blocking every few months.
What you are paying for, in plain terms
A relined drain is a new pipe inside the old one. A cured-in-place liner has a design life in the order of 50 years, and because it is jointless there are no joints for roots to find. So the cost buys you a long-term fix, not another temporary clear. That is the difference worth weighing when the per-metre number looks steep, you are comparing a one-off fix with a recurring cost that never ends.
How we quote it honestly
We will not give you a firm relining price down the phone, because anyone who does is guessing. The honest process is a CCTV camera survey first, so we can see exactly what is damaged, how long the failed section is, where the junctions are and whether relining is even the right call for your drain. From that footage we quote the actual metres, the actual junctions and the actual access. You get the footage and the report either way, so even if you decide not to proceed, you own a clear picture of your drainage.
If your drain is blocked right now, the first job is clearing it, then deciding on the structural fix. See our blocked drains service and the pipe relining guide for the full picture, or read the blocked drains pillar for everything in one place. When you want a number for your place, get in touch and we will get a camera down the line.
