Same-day drain clearing on the Lower North Shore.
Blocked sinks, toilets and shared stacks cleared in North Sydney — jetted back to full bore rather than punched through, so it stays clear longer than a fortnight.

North Sydney is 84.4% apartments with very little private drainage anywhere, and it changed character completely in the 1970s when the office towers went up. The result is residential buildings sharing a network with a major commercial centre — food tenancies, offices and towers all contributing. Grease and wipes in shared stacks account for the overwhelming majority of blockages, and the scale of the commercial load makes it worse than the residential density alone would.
How people live in a suburb decides what blocks its drains. The higher the apartment share, the more of the drainage is shared stack rather than private line — and shared stacks block on what a whole column of kitchens and bathrooms puts into them.
North Sydney sits in the North Sydney Council, postcode 2060. About 83 metres above the harbour, three kilometres north of the CBD and directly across the bridge from it.

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.
On a tall stack the obstruction is at the base and the symptom appears wherever water finds relief.
A mixed-use building carries kitchen waste that no household contributes.
Identifying and reaching the right riser in a tower frequently takes longer than the clearing does.
Fat and wipes at the base of a tall stack, with commercial tenancies contributing load no household does. With 84.4% apartments and very little private drainage anywhere, essentially every finding here is inside a building.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
Laid out as the St Leonards township in 1836 and incorporated in 1890, but the suburb standing today is largely a product of the 1970s onward. Towers built in one burst means a lot of buildings reaching the same maintenance milestones at the same time.
Fat does not respond to a plunger and barely responds to a cable, so the order here usually starts with jetting.
Fat coats the pipe wall; a cable bores a hole through it and the line closes over again within weeks. Jetting scours the wall back to full bore, which is the difference between clearing a drain and cleaning it.
Shows whether the line was genuinely cleaned or merely opened — the distinction that decides if you are back in a month.
Less common in the apartment stock, but the older detached streets still see it — a cutting head takes the mass out and restores flow.
Rarely needed for a grease problem alone, but the answer where jetting reveals a damaged section underneath the build-up.
Identify the affected line before clearing anything — in buildings this size, clearing the wrong branch wastes a visit and the problem persists. Jetting scours a stack back to full bore. Strata or building management authorises the work in almost every case, so that contact is on the critical path from the first call.
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 North Sydney property and we’ll tell you straight — including when the simple clear is the whole job.
In a building, the first thing worth knowing is whether it is only your unit. If a neighbour has it too, the fault is in the shared line and nothing you do inside your own bathroom will change it.
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 North Sydney and the rest of the Lower North Shore. More on emergency plumbing.
Buildings that jet their stacks on a cycle spend materially less than those waiting for a backup, and in a suburb where towers went up in one burst, a lot of buildings hit that maintenance point together.
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.
Scoured back to full bore rather than opened just enough to run, which is what stops it closing over again in a month.
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 North Sydney:
Most often for one reason here: residential plumbing inside a commercial centre. Fat and wipes at the base of a tall stack, with commercial tenancies contributing load no household does. With 84.4% apartments and very little private drainage anywhere, essentially every finding here is inside a building. 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 North Sydney 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 and high-pressure jetting $250–$600. Grease jobs sit toward the jetting end, because cabling through a fat layer buys weeks rather than years. Those are market ranges rather than Voyager’s price list. Identifying the right riser and getting authorised access to it. In towers the clearing itself is rarely the long part — reaching the correct line, through the correct manager, at a permitted hour, is. We price by the job, not the hour, and you approve the number before anything starts.
Rarely. Supermarket products are designed for a hair clog in a basin, not a fat layer coating a metre of pipe wall — they open a channel through it at best. They also make the line hazardous to work on afterwards. If a chemical has already gone down, say so before anyone opens it up.
If it is a genuine one-off — something went down that shouldn’t have — clearing it is the whole job. If a kitchen or stack line has closed over before, a camera afterwards is what tells you whether it was actually cleaned or merely opened. We would rather tell you it is fine than clear it twice.
North Sydney is 84.4% apartments, so this comes up constantly. If the line serves more than one lot it is generally common property and the owners corporation’s to arrange; if it serves only your lot it is yours. We establish which before work is authorised and deal with the strata or building manager directly — the plumber page for North Sydney covers the ownership rules in full.
Density plus commercial load. North Sydney is 84.4% apartments and doubles as a major office centre, so residential stacks share a network with food tenancies and commercial buildings. More fat enters the system than the residential population alone would produce, and the towers largely went up in one burst — so many of them reach the same maintenance milestones at the same time.
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.
