Fabricating new pipework on site

Old clay lines, steep sandstone blocks and drainage repairs that genuinely last

A drain that blocks every summer is not a clearing problem, it is a pipe problem. Clearing pulls the roots out; repair keeps them out.

What we actually deliver. We find where the line has truly failed, tell you honestly whether a section repair or a full re-lay is the right call, then build it so the fault does not come back next wet season. See the whole silo at our drainage hub.

What makes drainage work different here

  • Clay under every original home The 1967 subdivision and the build-out that followed left nearly the whole suburb on earthenware clay drainage, now fifty to sixty years old, brittle at the joints and well past the age where patching holds for long.
  • Roots with nowhere else to go Backing onto the Berowra Valley bushland edge and shaded by heavy native canopy, the trees here hunt water relentlessly, and a hairline crack in a clay joint is an invitation they never refuse.
  • Fall you cannot fake Sitting on a ridgeline around 180 metres with gullies dropping toward the valley, blocks here either drain beautifully or concentrate every drop at one low point, so any new run has to be engineered for the fall, not just laid flat.

Drainage repair and installation services we provide: what we actually build

We repair, replace and install the full run of drainage around a home, from a single cracked reach under the backyard to a complete re-lay on a renovating property, with the line camera-verified before and after every job:

New drainage runs

When a renovation, extension or failing line calls for brand new drainage, we design the run to suit your block's fall, trench or tunnel where access allows, and lay PVC that roots cannot pry apart, then backfill and compact properly.

Sectional pipe replacement

Cracked earthenware under homes from the 1967 subdivision rarely needs a whole-of-property dig, so we camera-locate the failed section, open only that reach, swap clay for sealed PVC and reinstate the surface carefully to match.

Stormwater line repair

Steep ridge blocks concentrate runoff into gullies and low points, so we regrade sagging stormwater runs, fit junctions and pits where water pools, and rebuild lines that summer storms have split or silted solid after heavy rain.

Full drain re-lays

Where a line has failed along most of its length, patching buys time only, so we quote a complete re-lay in modern PVC, engineered for the fall your sloping block demands and backed by our workmanship guarantee.

Reactive clay, summer storms and the ground under Westleigh

  • The soil itself moves The suburb's reactive clay sits over shale and rock, swelling through humid summers and shrinking in cool winters, flexing buried pipes until joints work apart, which is why we bed replacements on stable compacted base rather than the same moving clay.
  • Storm season concentrates everything Intense summer storms on the ridge send runoff surging down steep blocks toward the same low corners, so we design pits and junctions for where the water actually gathers, not where a textbook says it should.
  • Older alterations complicate the map Bathrooms and kitchens refreshed over the decades sometimes tie newer waste lines into the original clay at awkward spots, so we camera-trace the full network before cutting into anything.

Common drainage problems we are called to fix

Root-split joints

Eucalypt roots threading into clay joints are the signature drainage fault around the bushland edge, and once a root mass has split a barrel, clearing alone never holds, so we excavate the damaged reach and replace it with sealed pipe.

Sagging and silted runs

Reactive clay soil swells and shrinks through the seasons, gradually bending shallow drainage runs until low spots trap silt and water, and we rebed those sections on stable compacted material so the fall actually lasts.

Why fixing the line properly matters: the cost of leaving it

Left alone, a failing line costs more with every season that passes, because the fault keeps working while the repair keeps getting bigger, and the damage rarely stays underground where you can see it:

Recurring blockages get worse, not better

Every root that gets trimmed back regrows thicker through the same crack, and each clearing visit costs money while the pipe underneath keeps deteriorating toward a full collapse.

Water goes where you least want it

A failed stormwater line on a steep block discharges against footings and retaining walls, and on reactive clay that moisture movement eventually shows up as movement you can see in the house.

A proper repair ends the cycle

Sealed PVC with correct fall and solid bedding gives roots nothing to grip and silt nowhere to settle, which is the difference between calling a plumber every summer and forgetting the drain exists.

How it works

Our drainage repair process, step by step

  1. 01

    Call and tell us

    Ring (02) 9072 0504 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

    Repair the line

    We excavate or access the failed section, remove the damaged pipe, lay and bed new PVC to the correct fall, flow test the finished run, then reinstate soil, garden or paving to match the rest of the yard.

  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 Westleigh

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 Westleigh 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.

If the fault turns out to be a blockage rather than a broken pipe, our blocked drains team clears and camera-checks the line first.

If the run is damaged but digging is the last thing you want, pipe relining can seal it from the inside. We also handle stormwater systems and CCTV drain inspections across the area, and on streets like Sefton Road and Ironbark Close, where original clay runs sit deep beneath established gardens, we trace the whole network before we quote.

Where we work

Areas we service

We carry out drainage repair and installation across the suburb and the surrounding Hornsby area, covering Thornleigh, Cherrybrook, Normanhurst, Hornsby and Pennant Hills, with the same licensed crew, upfront fixed pricing and lifetime-backed workmanship whether the job is a single cracked joint or a complete re-lay.

Good questions, straight answers

Drainage repair questions from Westleigh locals

How do you know if a drain needs repair rather than just clearing?

Recurring blockages in the same spot, gurgling fixtures, wet patches in the garden or a camera inspection showing cracked joints all point to a damaged line that clearing alone will not fix.

Do you replace old clay pipes with PVC?

Yes, because most homes built here after the 1967 subdivision were laid with earthenware clay, and we replace failed sections or whole runs with sealed PVC that tree roots cannot pry apart.

How much does drainage repair cost?

Every job is priced individually after a proper inspection, and you receive a single fixed written price before any work begins, with a $0 call out fee and nothing added afterwards.

Can you repair drains without digging up the whole yard?

Often yes, because we camera-locate the exact failed section and open only that reach, and where excavation can be avoided entirely we discuss pipe relining as a no-dig alternative.

Do you work beyond the suburb itself?

We cover Thornleigh, Cherrybrook, Normanhurst, Hornsby and Pennant Hills as well, bringing the same licensed crew, the same fixed written pricing and our Lifetime Labour Warranty to every drainage job we take on nearby.

How long does a drainage repair take?

A sectional replacement is usually finished within a day, while a full re-lay of a long run can take several days depending on depth, access and how much reinstatement the surface needs.
