A real person answers, day or night
The main line deserves better than a quick poke
A blocked sewer is usually structural or root-driven, not a simple clog. We diagnose the actual cause with a camera before quoting, because clearing the symptom without understanding the line only books you a return visit in a few months.
A century of sewer mains under the ridge streets
The earliest streets here still run earthenware lines laid when the subdivisions went in, joined with cement mortar that cracks as the ground moves through hot summers and crisp ridge winters.
Roots find those old joints with precision. Around the sports grounds and bowling greens on Lodge Street, mature figs and gums planted decades ago have spent seventy years hunting moisture, and their roots thread into cracked joints until the main chokes. A sewer blockage on these blocks is rarely bad luck; it is an ageing pipe meeting a thirsty tree, and diagnosis starts by working out which one is winning.
Our blocked sewer service
We treat the main line as a system to be diagnosed, cleared and protected, not a one-off blockage to be chased, and every job below comes with the same upfront fixed pricing:
CCTV main line inspection
The camera runs the full length of the sewer, locating root masses, cracked earthenware joints and displaced sections so the quote covers the true fault, not a guess.
High-pressure jetting
Root cutters and jetting nozzles strip the line back to clean walls rather than poking a hole through the blockage, which keeps the main flowing for years instead of weeks.
Patch relining and joint sealing
Where the clay pipe has cracked but not collapsed, a resin liner seals the damaged section from inside, denying roots their entry point without excavating the garden.
Excavation and replacement
Collapsed or severely degraded sections are dug out and replaced with modern PVC, graded correctly across the block's fall toward the gully.
After-hours emergency clearing
A sewer backing up into the bathroom or laundry cannot wait, and we answer day or night, including weekends.
Slope, sandstone and where the flow gathers
This ridge-top setting shapes how sewer lines fail, because sandstone slopes fall away into gullies toward the bushland edge and every line has to be graded across that fall.
Hand-cut falls were never perfectly consistent. On the long runs of the early decades, low spots settle in where solids drop out and build up slowly over the years, and everything from mature street plantings to remnant bushland species pushes roots downslope toward the moisture those old lines carry. A main on a falling block near the national park boundary behaves differently from one on a flat street near the shops, so jetting pressure, inspection points and repair strategy are set per job.
Why sewers block in the older homes here
- Root intrusion at clay joints Cement-mortared earthenware joints from the early subdivisions shrink and micro-crack over decades, and fine roots thread through, thicken, and eventually choke the whole main until nothing passes.
- Degraded earthenware pipe walls A century of soil movement and surface loads leaves old pipe walls brittle and pitted, so sections crack, sag or collapse outright rather than simply clogging.
- Scaled and grease-coated mains Decades of household discharge coat the inside of older lines, narrowing the bore until a single flushable wipe or food scrap becomes the plug that stops the lot.
Why clearing the main properly matters
A sewer that backs up is not just inconvenient; untreated wastewater surfacing on your block or inside the house is a genuine health hazard, and the damage compounds daily:
- Protects the household's health Sewage carrying bacteria into bathrooms, laundries and gardens exposes your family to real infection risk, so a fast, complete clear is the only safe response.
- Prevents structural damage Wastewater finding cracks under floors and along pipe runs erodes footings, rots subfloor timbers in weatherboard cottages and stains brickwork the garden hose will never fix.
- Saves repeat call out money Clearing the blockage without fixing the cause guarantees another backing-up main within months, while a proper diagnosis and repair ends the cycle.
How it works
How we clear a blocked sewer
- 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
Diagnose, clear and prove
The camera confirms where and why the main is blocked, jetting or root cutting clears the line completely, and a second camera pass verifies the full bore is clean before we discuss any permanent repair the footage justifies.
- 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 Asquith
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 Asquith 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
We clear blocked sewers throughout the local area and across the wider Hornsby district, covering North Wahroonga, Hornsby, Mount Colah, Waitara and North Turramurra with the same camera-first diagnosis and fixed pricing, backed by a team that knows which streets run on which era of pipework before we arrive.
Good questions, straight answers
Blocked sewer questions Asquith locals ask
How do I know the blockage is in the sewer main?
Every fixture gurgling or backing up together, especially the lowest ones in the house, points to the main sewer line rather than one branch.
Can tree roots be removed without digging up the yard?
Yes, most root intrusions are cut back with jetting equipment through an access point, and a camera inspection confirms the line is clear.
Will you confirm the cause before quoting?
We run a CCTV camera along the line first, show you the fault on screen, and quote a fixed price for the full repair before work starts.
Do older clay sewer pipes always need replacing?
Not always, because patch relining can seal cracked clay joints from inside the pipe, but collapsed sections genuinely need excavation.
What should I do while waiting for the plumber?
Stop using all water, avoid flushing toilets, and keep everyone away from any wastewater that has surfaced outside.
Is a blocked sewer covered by Sydney Water?
Usually not, since the branch lines and most private mains on your property remain the owner's responsibility, though we can advise where the boundary sits.
