Costs
How much does pipe relining cost in Sydney?
Pipe relining in Sydney is commonly quoted in the range of $500–$800 per metre, so a typical residential job runs from around $2,500 up to $10,000 or more depending on pipe length, diameter, access and damage. Terry quotes each relining job after a CCTV camera inspection, so the price reflects the actual pipe, not a guess.
In Sydney, pipe relining is commonly quoted between $500 and $800 per metre as an industry range, and the honest answer to what a specific job costs only arrives after a camera goes down the pipe. Terry quotes relining after a CCTV inspection for exactly that reason: the price then reflects the actual pipe rather than an estimate made over the phone.
What the numbers look like in practice
- Short patch repairs, a single cracked section or a bad junction, often land between $800 and $2,500.
- A typical residential sewer reline of 5 to 10 metres commonly falls between $3,000 and $8,000.
- Long runs, larger diameter pipe or multiple junctions can push past $10,000.
These are industry figures for the Sydney market, not a price list. Every reline is priced for the specific job, with the price agreed up front once the inspection has shown the length, diameter and condition of the pipe.
What pushes the price up or down
- Length of the damaged section. Relining is priced per metre, so a 3 metre patch and a 15 metre full-length line are very different jobs.
- Pipe diameter. A standard 100mm house sewer costs less per metre than a 150mm line.
- Junctions. Each branch connection has to be cut back open with a robotic cutter after the liner cures, which adds time and cost.
- Access. A pipe reachable through an inspection opening in the front yard is cheaper to line than one that starts under the house slab.
- Condition. A pipe with a few root-affected joints is a straightforward candidate. A partially collapsed pipe may need a small dig at the collapse point before the rest can be lined.
Relining versus digging
Excavation can look cheaper per metre, and in an open lawn with a shallow pipe it sometimes is. The comparison changes completely when the pipe runs under a driveway, a garage, established landscaping or the house itself. Digging then means demolition and reinstatement: concrete cutting, possible structural engineering, and putting everything back afterwards, which regularly doubles or triples the headline price. Relining works from existing access points, so the driveway stays intact and most jobs are finished in a day. As a rule of thumb, the more valuable the surface above the pipe, the stronger the case for relining.
Why the camera comes first
A CCTV drain inspection in Sydney generally costs $200–$400 and answers the questions that actually decide the price: where the damage is, how long the affected section runs, what the pipe is made of, and whether relining is even the right fix. Sometimes the camera shows a single bad joint where a $1,000 patch does the work of a feared $8,000 reline. Sometimes it shows a collapse that no liner can bridge. Either way, nobody should be quoting thousands of dollars for underground work they have not seen, and it is entirely reasonable to ask any plumber to show you the footage.

Frequently asked questions
- Is pipe relining cheaper than replacing the pipe?
- Under driveways, slabs or landscaping, relining is usually cheaper overall because it avoids demolition and reinstatement, which often cost more than the pipework itself. In open ground with shallow pipe, a dig-and-replace can be competitive. The camera inspection tells you which situation you are in before any money is committed.
- How long does pipe relining last?
- Quality liners are engineered for a design life of around 50 years, and manufacturers back them with long warranties. The cured liner forms a smooth, jointless pipe within the old one, which is why relined sections resist tree roots better than the original clay pipe ever did. Roots enter at joints, and a liner has none.
- Can every pipe be relined?
- Most, but not all. A liner needs a continuous path to follow, so a fully collapsed section cannot be relined and needs a targeted dig at that point first. Badly back-falling pipes are also poor candidates, since relining follows the existing alignment. This is precisely what the CCTV inspection establishes before quoting.
- How long does a pipe relining job take?
- Most residential relines are completed in a single day, including cleaning the pipe, installing and curing the liner, and reopening any junctions. Water can usually be used again the same evening. Compare that with excavation under a driveway, which can stretch across several days plus concrete curing time.
- Does home insurance cover pipe relining?
- Sometimes, but read the policy carefully. Insurers often cover sudden damage, such as a pipe broken by an identifiable event, while excluding gradual deterioration and tree root intrusion, which is what most relining fixes. Get the CCTV report first, then talk to the insurer before booking work, since the footage is exactly the evidence they ask for.
