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

Cremorne Point is 79.9% apartments on a narrow finger of land falling away steeply on both sides. Almost every job here is a building matter — a stack serving a column of units, blocking on the fat and wipes that a whole building contributes. The peninsula then adds its own complication: one road in, one road out, and long service runs from the buildings down to the main.
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.
Cremorne Point sits in the North Sydney Council, postcode 2090. A narrow peninsula extending south into the harbour, falling away steeply on both sides.

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 blockage is at the bottom and the symptom is wherever the water finds relief — often several levels up.
Waste backs up at the lowest point, which is rarely the unit responsible.
A stack narrows gradually. Several units reporting sluggishness over months is a maintenance signal.
A build-up at the base of a long stack, with the reported symptom often several floors above it. Long service runs from the buildings down to the main are the other recurring feature — more pipe between the building and the network than the site suggests.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
The point carried the Cremorne Gardens pleasure grounds from 1856 and was built out residentially through the last century, so the buildings here are largely older strata with plumbing of a similar generation. Long runs of aged stack pipe is the characteristic condition.
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 which line is affected before anything is cleared — on a building with long runs, clearing the wrong branch achieves nothing and the problem persists. Jetting restores the full bore of an aged stack better than a cable does. Access on the point is planned rather than assumed, because there is no second route in.
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 Cremorne Point 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 Cremorne Point and the rest of the Lower North Shore. More on emergency plumbing.
Buildings that jet on a schedule rather than waiting for a backup spend materially less over a decade, and on a peninsula where an emergency visit is harder to arrange that gap is wider than usual.
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 Cremorne Point:
Most often for one reason here: shared stacks on a peninsula with one way in. A build-up at the base of a long stack, with the reported symptom often several floors above it. Long service runs from the buildings down to the main are the other recurring feature — more pipe between the building and the network than the site suggests. 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 Cremorne Point 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. Run length and access. One road in and one road out means equipment and timing are planned rather than assumed, and a long stack takes longer to scour properly than a short one. 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.
Cremorne Point is 79.9% 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 Cremorne Point covers the ownership rules in full.
That is normal on a tall stack. The obstruction sits at the bottom; waste backs up until it finds the first available relief point, which can be several floors above the actual fault. It is why diagnosing from the reporting unit alone is unreliable in buildings like the ones on Cremorne Point.
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.
