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

Artarmon is 68.4% apartments, so most blockages here are not in a private drain at all — they are in a stack serving a column of units. That changes the cause. A stack blocks on what a dozen kitchens and bathrooms put into it: cooking fat that cools and sets on the pipe wall, and wet wipes that do not break down no matter what the packet says. It also changes the symptom, because the fault usually shows up in the lowest unit rather than the one causing it.
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.
Artarmon sits in the City of Willoughby, postcode 2064. Ridge-top ground at about 88 metres elevation, which makes it flatter and easier to work than the harbourside suburbs east of here.

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.
A gurgling or slow drain appearing in more than one unit at the same time points at the shared stack, not at any one bathroom.
Waste backs up at the lowest point in the stack, which is why the unit reporting the problem is often not the unit causing it.
A drain that clears easily and blocks again within months is telling you the cause is still in the pipe — usually a build-up on the wall or a root at a joint.
In the apartment stock it is almost always a build-up on the pipe wall at the base of a stack — congealed fat with wipes caught in it, sitting where the vertical line turns horizontal. On the Federation streets it is the opposite picture: a root at an earthenware joint, with the pipe otherwise sound.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
The Federation-era streets carry the oldest drainage in the suburb, and pipework of that age is typically salt-glazed earthenware laid in short lengths. Every joint is a potential entry point once the ground moves. The apartment stock is far newer and mostly PVC, which does not admit roots the same way — but does hold grease just as well.
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.
On a shared stack the sequence matters: locate which line is affected before anything is cut or cleared, because clearing the wrong branch achieves nothing and the building still has a problem. A camera answers it quickly. Ridge-top ground at around 88 metres means there is reasonable fall to work with here, which is not true of the harbourside suburbs to the east.
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 Artarmon 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 Artarmon and the rest of the Lower North Shore. More on emergency plumbing.
In a unit, the fat is the thing you control: scrape pans into the bin rather than the sink, and treat ‘flushable’ wipes as not flushable. Buildings that jet their stacks on a schedule rather than waiting for a backup spend less over a decade.
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 Artarmon:
Most often for one reason here: grease and wipes in a shared stack. In the apartment stock it is almost always a build-up on the pipe wall at the base of a stack — congealed fat with wipes caught in it, sitting where the vertical line turns horizontal. On the Federation streets it is the opposite picture: a root at an earthenware joint, with the pipe otherwise sound. 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 Artarmon 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. Which line it is decides the price. A stack in a block means building access, often out of hours, and identifying the affected branch before anything is cleared. A house drain on the older streets is straightforward by comparison — the cost there is in what the camera finds afterwards. 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.
Artarmon is 68.4% 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 Artarmon covers the ownership rules in full.
It is common in Artarmon, where 68.4% of dwellings are apartments, and it is usually avoidable. A stack that blocks repeatedly has a build-up that clearing never fully removed. Jetting scours the wall properly, and a camera afterwards shows whether the line is genuinely clean or just open. Scheduled maintenance costs a building less than repeated emergency callouts.
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.
