A new pipe inside the old one

The idea is easy to describe and demanding to execute. A resin-soaked liner is pulled or inverted into the failing run, pressed against the old walls and cured into a smooth, jointless surface that roots find nothing to grip and cracks cannot leak through. For the full drainage picture, see our drainage services.

Preparing a liner to repair a pipe from the inside

Why the local drains suit relining

The earliest streets near the railway station, running since 1886, were laid with earthenware clay sewer and stormwater lines now well past their design life.

  • The clay has aged out Federation and bungalow-era earthenware cracks, shifts and misjoins as the shale and rock ground beneath it moves through wet and dry seasons.
  • The canopy is hungry Mature trees along the bushland edge near Larool and Waitara Creeks send fine roots hunting through those ageing joints every growing season.
  • Digging costs more than the pipe Excavating a failed run under an established garden means losing trees, paving and patience, which is why we recommend relining constantly on this side of the plateau.

Before any liner goes in, the pipe gets a full CCTV drain inspection so we can see the cracks, offsets and root intrusion on video and quote the right repair, not a guess.

Pipe relining services we provide

Our relining covers sewer lines, stormwater runs and everything in between:

Sewer line relining

We pull a resin-soaked liner through the damaged earthenware sewer, inflate it against the pipe walls and cure it into a seamless new pipe that denies fine roots any purchase, all without excavating the garden beds or existing paving above.

Stormwater pipe relining

Cracked clay stormwater runs on the low side of sloping blocks let groundwater and silt in continuously, so we reline the full length from access point to boundary, restoring a watertight fall that handles summer storm run-off properly.

Localised patch liners

Not every fault needs a full liner, so where a camera survey shows one cracked joint or short fractured section we install a targeted patch, sealing the defect only and leaving the rest of the sound pipe untouched.

Root cutting before relining

Fine root mats must be stripped out first, so we jet and mechanical-cut the intrusions back to the pipe wall, verify the walls are clean on camera, then line the run so regrowth has nothing to hold.

What the streets tell us

The housing mix decides which faults we see, and this pocket of the plateau has a very particular split:

  • Near the station and the orchard-era streets The pre-war brick homes hold the oldest earthenware runs, where a liner turns a recurring embarrassment into a set-and-forget fix.
  • Out toward the Brickpit and the bush edge Later brick and brick-veneer homes carry younger PVC, but aggressive root growth at the joints and storm surcharge on sloping blocks still find their weak points.

Either way, the answer starts with the camera, not the shovel.

Problems relining solves for good

These are the faults we reline most often around the area:

Recurring root blockages

A drain that blocks every wet season usually has roots living inside a cracked clay joint, and clearing alone only trims the symptom back, so we reline the damaged run and remove the entry point for good.

Collapsed or misaligned clay

Federation-era earthenware lines shift as the ground moves beneath them, and where a section has dropped or fractured we confirm the extent on camera and reline a new structural pipe through it.

Odours and damp ground

Sewer gas escaping through hairline cracks, or unexplained damp patches along a pipe route, points to a structural fault rather than a simple blockage, and relining seals those cracks from inside without opening the lawn to find them.

If the blockage is the urgent part rather than the pipe itself, our blocked drains team clears the line first, and a chronic sewer-side fault may need our blocked sewer specialists instead.

Why relining beats replacing

Every year you leave a cracked line unattended, the problems compound:

  • Roots keep widening the gap A hairline crack today becomes a root-packed collapse in a few wet seasons, and a collapsed section underground costs far more to fix than a liner placed early.
  • Excavation damage is its own bill Digging a trench through established gardens, driveways and paving adds reinstatement costs and months of mess that relining simply never creates.
  • A smooth liner flows better The cured liner restores full internal diameter with a slick, jointless wall, so waste and stormwater move freely and silt has nowhere to catch again.

Where a pipe is too far gone for a liner, our drainage repair and installation team handles the replacement instead, and we will tell you honestly which option your pipe qualifies for.

How it works

How our relining process works

  1. 01

    Call and tell us

    Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.

  2. 02

    Quote before work

    Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.

  3. 03

    Clean, measure and cure

    We jet the line clear, take exact internal measurements, soak the liner and invert it into place, then cure it hard before a final camera pass confirms a smooth, watertight new pipe wall inside the old one.

  4. 04

    Backed for life

    Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.

Why choose Your Plumber Thornleigh

Fixed prices, kept

Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.

Licensed and insured

Your Plumber Thornleigh works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.

Lifetime Labour Warranty

Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.

Genuinely local response

We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.

Where we work

Areas we service further afield

Alongside relining drains here, we carry the same no-dig equipment through Normanhurst, Pennant Hills, Westleigh, Hornsby and Wahroonga, where the same leafy streets and pre-war clay drainage stock produce the same root and crack faults, and our vans are stocked for first-visit fixes across the whole patch.

Good questions, straight answers

Pipe relining questions local drain owners ask

How long does a relined pipe actually last?

A properly cured liner forms a jointless structural pipe inside the old one, rated for decades of service, and our Lifetime Labour Warranty backs the workmanship behind every installation we complete.

Can the clay drains near the railway station be relined?

Most can, because the Federation-era earthenware lines around the station usually crack or misjoin rather than fully collapse, and a camera survey confirms whether a liner can restore each run without excavation.

Is relining more expensive than digging the pipe up?

The quote is often comparable once excavation, reinstatement of gardens, paving and landscaping are counted, because relining finishes in days while a dig can leave your yard recovering for months.

Do you need to dig any access points?

Usually only a small excavation at an existing opening or boundary trap gives us the entry we need, and we restore that spot neatly, so lawns, driveways and established garden beds stay intact.

How long does the whole relining job take?

Most residential runs are cleaned, measured, lined and camera-verified within one to two days depending on length and access, and we give you the schedule in writing before any work begins.

Does relining stop tree roots coming back?

Yes, because the cured liner presents a smooth, jointless wall with no cracks or rubber-ring joints for fine roots to grip, removing the entry points that mature street trees exploit year after year.
