Same-day drain clearing on the Lower North Shore.
Blocked sinks, toilets, showers and main sewer lines cleared in Naremburn — with a camera down the line so you find out what caused it, not just that it moved.

Naremburn was established as Central Township and built out as modest workers’ housing — cottages on small blocks, close together, with 19.5% of dwellings now semis or terraces against 37.8% houses and 42.7% flats. The tight original subdivision is what shapes the drainage problems: short setbacks, lines running close to boundaries, and in a lot of cases runs that serve more than one property.
How people live in a suburb decides what blocks its drains. A split like this one is why no assumption holds across the suburb — the same fault means something different depending which type of property it is in.
Naremburn sits in the City of Willoughby, postcode 2065. About 74 metres across 1.71 square kilometres, six kilometres north of the CBD.

A drain rarely stops working without warning. These are the patterns worth acting on here — each one points at a different cause, which is what decides the fix.
Houses, semis and units all present differently, and Naremburn has substantial amounts of each.
Tight setbacks mean machine access is often impossible, which rules out options before anyone quotes.
Close subdivision means a run frequently crosses a boundary.
Shared lines on the cottage blocks more often than owners expect — the original subdivision was tight, and runs cross boundaries. In the 42.7% that are flats it is the usual stack build-up, and on the freestanding cottages, roots into Federation-era pipe.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
The earliest land grants date to 1794, and the cottage stock carries drainage from the late Victorian and Federation periods — jointed earthenware laid to the standards of cheap housing rather than generous housing. Later apartment development brought newer pipe into the same streets.
Which of these a job needs depends entirely on the property, which is why we look before quoting.
Shows what caused the blockage and whether the pipe is damaged. The step that stops you paying twice.
Scours the pipe wall back to full bore rather than punching a hole through a build-up.
A cutting head removes the root mass itself. It restores flow, but roots grow back through the same opening.
A new liner cured inside the old pipe, sealing the joints roots came through. No excavation, so nothing above the pipe comes up.
Access is the constraint that decides method here more than the blockage is. With no room for machinery beside most cottages, working inside the existing line is usually the only practical route — clear, inspect, and where the pipe has failed, reline. Worth noting Naremburn sits in the City of Willoughby while its neighbours do not.
Nobody likes ringing for a price and being told “it depends”. These are typical ranges across the Sydney market — not Voyager’s price list, but a realistic yardstick to judge any quote against, including ours.
| Clearing a simple blockage | $150 – $400 |
| Clearing a blocked main sewer line | $300 – $600 |
| High-pressure jetting | $250 – $600 |
| Cutting tree roots from a line | $400 – $1,200 |
| CCTV drain inspection | $250 – $550 |
| Pipe relining, per lineal metre | $450 – $800 |
| Pipe relining, typical whole job | $4,000 – $10,000 |
| Excavate and replace, per metre | $300 – $600 |
Voyager prices by the job, not by the hour, so the number you approve is the number you pay.
Describe what’s happening at your Naremburn property and we’ll tell you straight — including when the simple clear is the whole job.
Note which fixtures are affected and whether any neighbour has the same thing. In a suburb as mixed as Naremburn that is what narrows down whether the fault is yours alone.
Stop using the fixtures on that line. Every flush and every sinkful adds to what has nowhere to go, and on a main sewer blockage that is what turns a contained problem into an overflow.
Do not pour drain chemicals down it. They rarely clear a real blockage, they make the line unsafe to inspect or work on, and caustic product sitting against an old earthenware joint does the pipe no favours.
If sewage is surfacing, treat it as urgent. That is a health issue, not an inconvenience — keep people and pets away from it and call.
If it is out of hours and getting worse, ring rather than book — Voyager runs a 24/7 line for Naremburn and the rest of the Lower North Shore. More on emergency plumbing.
On a tight block, knowing whether your line is shared is worth establishing before there is a fault rather than during one. It changes who needs to agree to the work.
Storm season finds every drain that was never quite right. Better to know before it rains.
Which fixture, how long, and whether anything is overflowing. That is usually enough to tell how urgent it is.
Jetting, cutting or a machine, chosen by what the line is doing — not by what is quickest to bill.
A camera down the cleared line shows whether this was a one-off or a pipe that will do it again.
Including when the answer is that nothing further is needed. A cleared drain with no fault is a perfectly good outcome.
A blocked drain is sometimes the symptom rather than the problem. These cover what comes next:
Voyager covers the whole Lower North Shore. These are the closest to Naremburn:
Most often for one reason here: workers’ cottages built cheap and close together. Shared lines on the cottage blocks more often than owners expect — the original subdivision was tight, and runs cross boundaries. In the 42.7% that are flats it is the usual stack build-up, and on the freestanding cottages, roots into Federation-era pipe. A drain that clears easily and blocks again within months is telling you the cause is still in the pipe — which is why we put a camera down a cleared line rather than leaving it at ‘it’s moving again’.
Voyager runs a 24/7 line for Naremburn and the rest of the Lower North Shore. If sewage is surfacing or a main line has stopped, say so when you call — that is what decides how fast someone needs to be there rather than the booking order.
Across the Sydney market a simple blockage typically runs $150–$400, jetting $250–$600, root cutting $400–$1,200 and a CCTV inspection $250–$550. Those are market ranges rather than Voyager’s price list. Access, and it is decisive. Setbacks on the workers’ cottages are narrow enough that machinery frequently cannot get beside the house at all, which removes the cheap excavation option before anyone quotes it. We price by the job, not the hour, and you approve the number before anything starts.
Rarely, and it can make things worse. Caustic product does not shift a root mass or a collapsed section, it sits in the line where it is a hazard to work on, and against an aged earthenware joint it does the pipe no favours. If a chemical has already gone down, tell us before anyone opens the line.
If it is a genuine one-off — something went down that shouldn’t have — clearing it is the whole job. If the same line has blocked before, a camera tells you whether this is maintenance or a repair being postponed. We would rather tell you it is fine than clear it twice.
Cutting the roots restores flow but leaves the opening they came through, so they return — usually within a year or two. Relining seals the joints from inside, which removes the entry point without digging up whatever sits above the pipe. On a tight block, knowing whether your line is shared is worth establishing before there is a fault rather than during one. It changes who needs to agree to the work.
Naremburn was built as modest workers’ housing on small blocks, close together, and those original setbacks are still what you have. Machine access beside the house is frequently impossible, which sounds like a problem but mostly is not — clearing, inspecting and relining all work from inside the existing line and need very little room.
Yes, and telling them apart matters — they present similarly from the surface and are fixed completely differently. A drain that only misbehaves in heavy rain is usually stormwater or ingress rather than a blockage. A camera settles it in one visit.
