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

Kirribilli is 86.8% apartments in half a square kilometre — effectively a vertical suburb, and almost every blockage is a building matter rather than a backyard one. Stacks block on what a whole building puts into them: fat, wipes and everything else that does not break down. The complication is underneath: this is land first granted in the 1790s with houses from the 1830s onward, so modern towers frequently connect into infrastructure far older than they are.
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.
Kirribilli sits in the North Sydney Council, postcode 2061. A compact half a square kilometre on the harbour, three kilometres from 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.
Almost always the stack. Nothing done inside a single apartment will change it.
Waste backs up at the base of the stack, so the unit reporting it is rarely the one causing it.
Restricted works on a listed building mean the method has to be agreed before anyone starts, not during.
Fat and wipes at the base of a stack, in a building that frequently connects into much older infrastructure than itself. Kirribilli’s twentieth-century towers sit on land built out from the 1830s, and the camera sometimes finds nineteenth-century pipe still carrying the load.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
Georgian and Gothic-revival houses were built here through the 1830s, ’40s and ’50s, and the twentieth-century apartment stock was layered on top of that fabric. Nineteenth-century pipe under twentieth-century plumbing is a genuine condition here, not a figure of speech.
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.
Building or strata management is the decision-maker on virtually every job here, and getting hold of the right one early is what stops a job stalling. Jetting restores an aged stack properly where a cable will not; on heritage fabric the camera comes first so the method can be chosen around what the pipe can actually take.
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 Kirribilli 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 Kirribilli and the rest of the Lower North Shore. More on emergency plumbing.
In a building this dense, individual behaviour matters less than the building’s maintenance schedule. A jetted stack on a regular cycle is the single most effective measure available here.
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 Kirribilli:
Most often for one reason here: vertical living on nineteenth-century ground. Fat and wipes at the base of a stack, in a building that frequently connects into much older infrastructure than itself. Kirribilli’s twentieth-century towers sit on land built out from the 1830s, and the camera sometimes finds nineteenth-century pipe still carrying the load. 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 Kirribilli 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. Heritage restrictions and building access. On a listed building the method has to be agreed before work starts rather than decided on site, and reaching the right strata or building manager early is what stops a job stalling. 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.
Kirribilli is 86.8% 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 Kirribilli covers the ownership rules in full.
It limits excavation and any work affecting the fabric, which in Kirribilli is a real constraint given houses here date from the 1830s onward. It rarely limits drain clearing itself. Where a repair is needed, relining works from inside the existing pipe and generally sits comfortably within heritage restrictions — but the camera comes first so the method can be agreed rather than improvised.
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.
