Trenchless sewer and drain repair
Pipe Relining Perth: Trenchless Sewer and Drain Repair
A cured-in-place liner rebuilds a broken sewer or stormwater pipe from the inside, reached through an access point that already exists on your property.
Cured in place
The liner bonds against your existing pipe wall and hardens into a new pipe inside it.
Drainage only
Sewer, stormwater and drain lines. Not a general plumbing outfit.
Across metro Perth
Fremantle, Joondalup, Rockingham, Mandurah and the suburbs between.
Why relining beats digging it up
Replacing a failed sewer line means locating it, trenching down to it, breaking out whatever sits on top, laying new pipe, backfilling and making the surface good again. A fair share of that bill is concreting, paving and landscaping, charged after the plumbing is finished.
Relining skips the trench. We reach the damaged run through an access point that is already there, clean it out, then draw a resin-saturated liner through it and cure it hard against the old wall. You end up with a pipe inside a pipe: continuous through the repaired section, with no open joints for roots to find, and a bore smoother than the clay or cast iron it took over from.
The four steps, in order
What we reline
Eight services, all of them drainage. Start with the line you think has failed, or with the camera if you are not sure yet.
The work is scoped differently depending on who owns the pipe, so there is a page forhomes and units, one forstrata schemes, one forcommercial property, and one onUV cured relining.
We cover metro Perth: Joondalup north, Fremantle west, Rockingham and Mandurah south. Older suburbs are mostly vitrified clay with open joints, which is what roots go looking for.
What a reline actually costs
Nobody can answer that over the phone, and an outfit that does is quoting a job other than the one under your property. The price moves with the length of the damaged run, the pipe diameter, the depth, the bends and junctions the liner has to pass, and what is on the surface above it. So the camera goes down first and the quote covers what it found.
Questions we get asked first
Can a fully collapsed pipe be relined?
No, and that is the honest limit of the method. A liner needs a host pipe to cure against, so a section that has caved in has nothing left to hold its shape and has to be dug up and replaced. A camera run tells us which situation you have before anyone commits to an approach. Where only a short length has failed with sound pipe either side, a point repair usually covers it without relining the whole line.
Will you dig up my driveway?
Relining is carried out through an access point that is already on the property, so in most cases nothing above the pipe is touched. Where a run genuinely has no usable access, we say so at the inspection rather than once the work has started and the concrete is already out.
How is relining different from having the drain jetted?
Jetting clears what is inside the pipe. Relining repairs the pipe itself. When a drain blocks again within months of a clear, the pipe is usually the reason, and clearing it a second time changes nothing about that. See blocked drains in Perth for how the two are told apart.
Do you reline water supply pipes?
No. We work on sewer, stormwater and drain lines, which are gravity systems. Pressurised water supply is a different job under different standards, and it is not what this business does.
How much of the pipe has to be relined?
Only the part that has failed, plus enough sound pipe either side for the liner to seal against. The camera measures how far the damage sits from the access point and how far it runs, and the scope is written from those two distances. A line with three separate failures spread along it is a different job to one bad joint, even when the total damaged length is the same.
Does relining make the pipe narrower?
The liner adds wall thickness, so the internal diameter does drop. In practice flow usually improves, because the losses in an old line come from scale, root intrusion and offset joints rather than from raw diameter, and a cured liner replaces all three with a smooth continuous surface. Where a run is already near the limit of its capacity, that trade-off is one of the things the inspection is checking for.
How long is the drainage out of action?
Drainage cannot be used while the liner is in and curing, so the real question is how long that takes on your job rather than how long the crew is on site. It depends on the length of the run and the curing method chosen. The timing goes to you in writing with the scope, once the inspection has shown what the job actually is.
Will my insurer pay for it?
That depends on the policy and on the cause, and nobody can answer it honestly without both. Sudden damage from an identifiable event is treated very differently to gradual deterioration or root intrusion, which many policies exclude outright. What we can give you is the camera footage and a written scope stating what was found and where, which is the evidence an insurer asks for either way. Take it to them before you assume the answer, and see the FAQs for the rest.
Book the camera run before you commit to anything
Tell us what the drain is doing and where the property is. We will arrange a CCTV inspection, then put the scope and the price in writing.
