A real person answers, day or night
One shared line, every drain in the house
The sewer is the last common path for the kitchen, laundry, bathrooms and toilets alike. A fault anywhere along it affects all of them at once. Call (02) 9072 0528 and describe what is happening.
Why local sewers fail the way they do
- The southern pocket runs earthenware The pre-1940 brick cottages and Federation homes still carry their original clay-jointed sewers, and those joints are precisely where trouble starts.
- Roots hunt the moisture Mature street trees and established gardens push searching roots through seeping clay joints, and the intrusion thickens season after season until the pipe fills.
- The towers share one line Apartment buildings rising from the late-1990s boom around the station run modern PVC but long common sewers serve dozens of units, so one fault affects every household above it.
Ground movement on a shale and sandstone ridge also works rigid old joints loose over the decades, which is why the camera goes down before any quote does. For the broader picture of everything we clear and reline, see our drainage hub.
What a sewer service covers
Every sewer job starts with seeing the fault, not guessing at it:
CCTV sewer diagnosis
We push a camera along the full run from an access point to locate the exact underground fault, recording root intrusion, cracked joints or sagging sections so the repair targets the real problem rather than a costly guess.
Root cutting and clearing
Intruding growth gets cut back, flushed away and treated at the joint so the same roots cannot simply regrow next season, a step that matters most around the older residential streets with their established canopies.
High-pressure jetting
Years of grease and soap residue line the sewer under busy commercial stretches, and jetting scours that hardened coating off the pipe wall right back, restoring full bore diameter instead of poking a hole through the blockage.
Trenchless pipe relining
Where roots have cracked an earthenware line under a driveway or garden bed, a resin-saturated liner cures into a seamless new pipe inside the old one, sealing every joint without excavating the surface above it.
Excavation and replacement
A section crushed by shifting shale or collapsed beyond repair needs renewal rather than clearing, so we expose the failed length, replace it with modern PVC and bed it in stable, compacted material.
The strata side of a shared line
Plenty of local sewer calls come from apartments near the station precinct.
- The line serves floors above and below A backup in a tower is rarely one household's problem, and access points usually sit in common areas.
- The decision belongs to the owners corporation We work with building managers on access, isolate the right section and put camera findings in writing so the strata meeting has something concrete to vote on.
- Responsibility gets sorted honestly If the fault sits inside one unit's boundary, we say so plainly, because nobody benefits from a repair billed to the wrong party.
That documentation habit also helps when a blockage traces back to builder-grade fittings from the late-1990s construction wave, where the line between wear and defect matters.
Common sewer problems, diagnosed properly
The sewer that blocks every few months
A sewer blocking repeatedly usually has roots regrowing through an old joint or a sag trapping solids, and repeated clearing without camera diagnosis just resets the clock until the next expensive callout.
Everything gurgling at once
When the downstairs toilet, shower and laundry all gurgle and rise together, the blockage is in the common line rather than any single fixture, which is the moment to stop using water and call.
Smells that never quite leave
A persistent odour near the gully or inspection opening often means a dried trap seal, a cracked vent or sewage leaking from a fractured joint underground, and none of these resolve themselves.
Why acting early matters
- Sewage goes where you live A surcharging sewer eventually discharges into a bathroom, laundry or yard, and cleanup and ruined flooring cost far more than the repair that would have prevented it.
- Small faults become structural ones A cracked joint left alone lets soil wash in and the pipe deform further, turning a relining job into an excavation under a driveway or slab.
- Health risks build quietly Bacteria from a leaking line sit in soil and subfloor spaces long before you see anything, particularly around older homes with garden gullies.
How it works
How we handle a blocked sewer, step by step
- 01
Call and tell us
Ring (02) 9072 0528 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
Renew the line
With the diagnosis confirmed, your plumber clears or renews the failed section using the method the footage supports, from root cutting and jetting through to relining or excavation, then flush tests the run to prove free flow.
- 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 Leonards
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 Leonards 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.
We cover the whole precinct and the five neighbouring suburbs, Crows Nest, Wollstonecraft, Naremburn, Artarmon and Greenwich, bringing the same camera-first sewer diagnosis and fixed pricing to every street, whether the property is a tower unit or a Federation cottage.
Good questions, straight answers
What locals ask us about blocked sewers
How do I know it is the sewer and not just one drain?
If several fixtures gurgle or back up together, especially the lowest toilet and shower, the fault lies in the common waste line rather than a single trap, and a camera check confirms it quickly.
Will you need to dig up my garden or driveway?
Not always. Where the pipe structure allows it, a cured-in-place liner renews the sewer from inside without excavation, and we only recommend digging when a section has collapsed beyond what relining can carry.
Are tree roots a common cause of sewer blockages around here?
Yes. The older Federation homes on the southern streets run clay-jointed earthenware sewers, and searching roots find those joints readily, especially through a dry Sydney summer.
Who pays for sewer repairs in an apartment building?
Blockages in shared sewer lines within the building are a strata or owners corporation matter, while faults in a single unit's fixtures belong to the owner, and we document findings so responsibility is easy to establish.
How quickly can you attend a sewer backup?
We treat sewage backing into a home as an emergency and prioritise it accordingly, with licensed plumbers answering the phone around the clock, including weekends and public holidays, so call the moment it starts.
Are you licensed for sewer work near Sydney Water assets?
Yes. Our plumbers are fully licensed and insured for drainage and sewer work, and where a repair touches Sydney Water infrastructure we handle the required approvals and compliance paperwork as part of the job.
