Blocked Sewer St Ives
1000+ five-star reviews
A blocked sewer is the worst kind of drainage fault: the entire property's waste has nowhere to go, so it comes back through the lowest fixtures. We clear main-line blockages across St Ives properly, then confirm the pipe will not do it again next month. The broader drainage picture, and the full range of what we do, sit one click away.

A real person answers, day or night
The main line matters more than any single drain
One slow shower is annoying. A surcharging sewer is a household standing still: toilets refuse to flush, gullies lift their grate covers, and every fixture adds to the mess. Main-line faults are a specialty of our drainage work, because local pipe age and terrain make them routine rather than rare.
Why sewers block here before they block elsewhere
- Clay lines past their prime The homes built after the 1959 rezoning mostly still run original jointed earthenware sewer mains, and decades of ground movement through reactive clay soil opens hairline cracks that roots find fast.
- Trees with deep motivation Blocks bordering the Garigal bushland edge and the leafy garden streets carry gums and other large trees whose roots chase moisture into those cracked joints, then grow into rope-thick masses inside the pipe.
- Ridge and gully falls Sewers here run down undulating slopes toward the bushland, and long, steep runs settle unevenly over decades, creating bellies where waste pools and solids collect long before roots even arrive.
How it works
How we clear a sewer main properly
- 01
High-pressure water jetting
We blast the blockage out with pressurised water rather than scraping at it with a mechanical eel, which cuts roots flush, flushes grease and sediment downstream, and leaves the pipe walls cleaner than any cable ever could.
- 02
Camera confirmation after clearing
Clearing without looking is guessing, so we run a camera along the cleared main to show you exactly what caused the problem, whether roots, cracks or a collapsed section, and record footage for the fixed quote. Deeper diagnosis is covered on our CCTV drain inspections page.
- 03
Root cutting and relief work
Where root masses have hardened into solid plugs, we cut them back to the pipe wall with the right cutting heads, restoring full bore, then flag the entry points so the relining decision rests on evidence.
- 04
Sewer relining and repair
Lines with cracks or repeat root entry get a structural fix through pipe relining, which builds a seamless liner that removes the joints roots use as doorways, leaving a smooth root-proof bore.

Why you should not sit on it
Sewer water inside the house
A surcharging main pushes waste up through the lowest shower or floor waste, and that is a contamination clean-up no family needs, on floors children and pets use daily.
Excavation grows more likely
Roots widen cracks into collapses, and a relined pipe today avoids a dug-up yard and a rebuilt sewer tomorrow, which matters double in mature gardens worth keeping.
The whole household stalls
A home without a working sewer cannot cook, wash or shower normally, and prompt clearing restores family life far more affordably than waiting and mopping.
How it works
Our process, start to finish
- 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.
- 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 report
We jet the main clear, then camera the full run so the footage shows whether roots, cracked clay or a sunken belly caused it, and we hand you the findings plainly, including the choice between monitoring, relining or repair, with the line confirmed flowing before we leave.
- 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 St Ives
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 St Ives 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 around the ridge
We clear sewers here and throughout the surrounding Upper North Shore, including Pymble, Gordon, St Ives Chase, Turramurra and Belrose, with the same jetting gear and camera equipment on every van, so the diagnosis never changes with the postcode.
Good questions, straight answers
Blocked sewer questions locals keep asking us
How do I know the blockage is in the sewer and not a single drain?
When multiple fixtures back up together, the lowest drains gurgling as others empty, the problem sits in the shared main line rather than an individual branch, and a camera inspection confirms it precisely.
Do tree roots really grow into sewer pipes that often here?
They do, because mature gums and large garden trees on generous blocks search for moisture, and jointed clay sewer lines installed during the mid-century build-out give them hairline entry points to exploit.
Can a blocked sewer wait a day or two?
A slow main can sometimes hold, but any backup into showers or over gully grates needs same-day attention, because sewer water carries health risks and the longer it sits the worse the damage becomes.
Will clearing a root blockage fix the problem permanently?
Clearing restores flow immediately, but if roots entered through cracked joints they regrow, so we camera the line after clearing and quote relining or a repair where the pipe itself needs fixing.
Does relining a clay sewer require digging up the garden?
Usually not. Relining installs a tough new pipe inside the old one through existing access points, so the lawn, paths and mature trees stay intact while the line gets a smooth, root-proof surface.
What does a sewer call out cost?
The call out and assessment cost nothing, and you receive a fixed written price covering the complete clearing job before any work begins, so you approve the figure with full knowledge first.
