Backed Up Right Now? Call and We Roll

Sewage rising or a toilet spilling over is not a wait-till-morning problem. Ring (02) 9072 0545 and you reach a real person at any hour, weekend or public holiday.

The voice on the line is a licensed plumber, not an answering machine. Same-day service, and we send someone to you right away.

First, shut off whatever tap is feeding the blocked line. Move children and pets well clear of the spill, and do not lift a grate or put a hand near the pit.

The clean-up is ours.

Catch it early

Signs You Have a Blocked Drain

Most blocked drains signal trouble before they fail outright. Act on the early clues and it stays a partial blockage instead of a flooded laundry.

  • Sinks and showers empty slowly. A pipe that is silting up drains sluggishly, and clearing it now is cheaper than clearing it after it stops entirely. Routine drain cleaning handles it.
  • Toilets glug and floor wastes bubble. That noise is air escaping past an obstruction, which tells you the main line is partly choked rather than a single fixture.
  • A sewage or rotten-egg odour hangs about. That smell means waste is stalling somewhere in the pipe, and it is frequently a blocked sewer needing a full clear.
  • The outdoor gully fills or spills over. When the gully cannot cope, wastewater has nowhere downstream to go. Treat it as your last warning before it comes up inside.
  • Toilet water sits high or drops low on its own. A bowl level that shifts by itself is reacting to pressure swings caused by an obstruction further along.
  • Soft ground or an oddly green patch appears on the lawn. A pipe cracked underground leaks and feeds the turf above it. A CCTV drain inspection locates the exact spot.

Local knowledge

What Causes the Blockages We Clear in Thornleigh

Local drains block for reasons written into the ground and the housing. Old pipe stock and heavy tree cover do most of the damage.

The pre-war pocket near the station and Comenarra Parkway was plumbed with earthenware clay sewer and stormwater lines. Decades on, those joints shift and crack, and the cracks catch waste until the line packs solid.

Then there are the trees. Heavy canopy along the bushland-edge streets near Larool and Waitara Creeks pushes roots into those cracked clay joints, chasing water.

Root-choked drains are one of the most common jobs we see here. The terrain makes it worse, because the undulating ridge-and-valley layout drives water and silt down into the low-side pits at the bottom of every fall.

Around Duffy Avenue and the streets off Comenarra Parkway, that mix of old clay, big trees and slope keeps us busy. We camera the line first, clear it, then reline any failing section rather than trench the garden.

Blocked drain repair fixes the cause, not just today's clog.

How we work

Our Process Finds the Cause, Not Just the Clog

Anyone can push a blockage along for a day. We find why it blocked and fix that, so it stays clear.

  1. 01

    A Real Person Picks Up

    Call (02) 9072 0545 and a licensed plumber takes the call, not a machine. We give you one price up front, so the cost is clear before anything happens.

  2. 02

    Camera Down First

    A drain camera goes into the line to find the blockage and read the pipe's condition. No digging, no guessing, and you see what we see on the screen.

  3. 03

    The Method Fits the Blockage

    Roots and packed build-up call for a high-pressure water jetter. A wedged solid obstruction is better cleared with an electric eel. We match the method to the pipe rather than force one approach on every job.

  4. 04

    Proven Clear, Then Options

    A second camera run shows you the line running free. Where a pipe has cracked or dropped, we lay out your choices between a repair and no-dig relining, every one covered by our lifetime labour warranty.

Straight pricing

Drain Clearing Costs, Explained Honestly

A blocked drain quote is not a lottery. There is no call-out fee, the quote is free, and you sign off on the price before we begin.

What sets the number is the actual job, never the hours ticked off:

  • Getting to the drain. A gully at ground level is fast work; a line buried under paving or deep in the backyard is not.
  • Where the trouble sits. A blockage near the fixture is a smaller job than one out at the main or partway down a fall.
  • Roots or a break. A root-invaded or fractured clay line wants jetting or a repair, not a quick rod-through.
  • Repair versus relining. Resetting a failing pipe with no-dig relining runs to more than a plain clear, though it spares you a trench across the lawn.

In the community, for the community

A Family Business That Gives Back to the Community

Ours is a family-run outfit, and this pocket of the plateau is somewhere we work most weeks, from the Marketplace end down to the quiet streets off Comenarra Parkway. In the community, for the community, is the way we go about it.

Away from the drains, we back causes that matter close to home. Ronald McDonald House Charities Sydney, Beyond Blue, Wayside Chapel and Pink Ribbon Day all draw our support, and we turn up for local events too.

Standing behind the households who trust us with their homes matters as much to us as the work itself.

Common questions

Thornleigh Blocked Drain Questions

Short answers to the questions Thornleigh homeowners raise most often, covering blockages, what it costs and how quickly we turn up.

What is pipe relining and do I need it?

Relining rebuilds a pipe without excavation. A resin sleeve is drawn through the damaged section and cured solid, leaving a fresh inner wall and no trench across your yard. It works well on cracked clay lines sitting under paving or lawn.

Who is responsible for a blocked sewer, me or Sydney Water?

The stretch from your boundary shaft back to the house is the owner's responsibility, so that is what we handle. If sewage is coming up at the street and the neighbours have it as well, Sydney Water owns that mains problem.

Are your plumbers licensed and insured?

Yes. We hold NSW plumbing licence #275278C, carry $20 million public liability cover, and hold Master Plumber accreditation. A licensed plumber does the drain work, never an unchecked subbie.

Do you offer a 24/7 emergency blocked drain service?

Yes, every day of the year. A real person answers the phone day or night, and a plumber is dispatched straight away when a drain backs up after hours or over a weekend.

What suburbs do you service around Thornleigh?

We cover the wider Hornsby Shire, including Normanhurst, Pennant Hills, Westleigh, Hornsby and Wahroonga. Same crew, same fast arrival across the plateau, whichever street you are on.

How much does it cost to clear a blocked drain in Thornleigh?

There is no call-out fee and the quote is free. We look at the drain, give you one price, and you approve it before we begin. Book online and take $50 off, or ask about the 10% seniors discount.
