When the Whole Sewer Stops, the Whole House Notices
- One slow basin Is an annoyance; a choked main is a household shutdown.
- Toilets gurgle The shower drains slower by the day, and then the lowest fixture makes the situation impossible to ignore.
- The deeper the blockage travels The more of the pipe it claims, so early action costs less.
We find it, clear it and repair the reason it happened, so the same call does not come back next season. For faults in a single fixture or branch line, our blocked drains page covers the more contained version of the job.

Sewer Services We Handle
Sewer work splits into clearing the immediate blockage and stopping the next one, and the job is only done when both halves are covered:
Sewer Main Clearing
High-pressure jets cut through grease, paper and sludge packed inside a choked main, restoring flow throughout the house, and clearing finishes in the same visit so your household gets its plumbing back without repeat appointments.
Root Cutting and Removal
Mechanical cutters slice eucalypt roots out of the pipe where they enter through cracked joints, and the debris gets flushed fully clear, buying years of useful relief for gardens that should never need digging.
CCTV Sewer Inspections
A camera travels the full length of the sewer line after clearing, showing exactly where roots entered and where clay has cracked, so you approve a fix based on evidence rather than guesswork, and our CCTV drain inspections page explains the process in full.
Pipe Relining for Sewers
A resin lining cures inside the damaged sewer pipe, sealing every root entry joint and crack without excavating lawns or driveways, and our pipe relining service suits exactly this kind of damaged clay run.
Excavation and Replacement
When a clay run has collapsed beyond lining, we dig only the failed section and replace it with modern PVC at the correct grades, then reinstate the surface properly for decades of trouble-free service.

Common Sewer Problems We Get Called To
Sewage Backing Up Indoors
The lowest fixture in the house overflows first when the main blocks, and keeping everyone away from that water matters because raw sewage carries health risks our clearing and disinfecting resolve.
Blockages That Keep Returning
A sewer that clears and then chokes again within months usually has roots regrowing through the same cracked joint, and without fixing the pipe itself the cycle repeats, so we camera-inspect rather than just plunging.
Multiple Fixtures Slowing Together
When the toilet, shower and basin all drain sluggishly at once, the blockage sits in the shared main rather than any single trap, and acting before sewage surges back saves a messy clean-up.
Why Ignoring a Choked Main Costs More Than Fixing It
Health exposure
Raw sewage carries bacteria into yards and floor levels, and once it reaches tiles or carpet the clean-up, disinfection and material replacement cost far more than the clearing call ever would have.
Pipe damage compounding
Roots wedging a cracked joint open pry it wider with every flush, converting a relinable crack into a collapsed run that needs excavation, and the repair bill climbs with the pipe's decline.
A house that cannot function
No laundry, no showers and guarded toilets make a home unliveable fast, so restoring the main quickly protects not just the property but everyone's routine inside it.
How it works
How We Get Your Sewer Flowing Again, Step by Step
- 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.
- 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.
- 03
Clear, inspect and price the permanent fix
Once flow is restored, the camera goes through the cleared main to find the exact cause, the findings go on screen for you, and the repair option, whether relining or targeted excavation, is priced in writing before anything further begins.
- 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 Hornsby
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 Hornsby 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.
Good questions, straight answers
Sewer Blockage Questions Hornsby Householders Ask
How do I know it's the sewer and not just one drain?
If several fixtures at the lowest level of the house back up together, or sewage appears in a gully outside, the shared main is blocked rather than one trap, and it needs professional clearing.
Are tree roots really the main cause around here?
Yes, mature blue gums and blackbutts along the bushland streets push fine roots toward any line carrying water, and the earthenware clay drains under pre-1940 homes crack at their joints, inviting root entry.
What should I do while waiting for the plumber?
Stop using every fixture, keep everyone away from any overflow, and avoid chemical drain products, because caustic residue sitting in a choked pipe makes clearing harder and can splash back toward whoever opens the line.
Can you fix the pipe without digging up the yard?
Often yes, pipe relining cures a new lining inside the damaged sewer, sealing cracks and root joints from within, and we only recommend excavation when a run has collapsed too far for a liner.
Is a blocked sewer an emergency?
It can be, because sewage rising through the lowest shower or laundry tub is a health hazard, so if overflow reaches living areas or pools near doorways, call straight away rather than waiting until morning.
Does sewer work need council or Sydney Water approval?
Most repairs within the boundary need no approval, but work touching the sewer main or junctions with Sydney Water's system can have requirements, and we confirm what applies before quoting so nothing surprises you.
