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

Lane Cove North began as a post-war veterans’ housing area and is now 70.8% flats across 5,550 dwellings. Those two facts sit uncomfortably together: original post-war drainage in parts of the suburb, modern high-density stock in others, and a shared network carrying both. Most call-outs here are stack blockages — fat and wipes — but the older pockets still produce the root-into-old-joint problem.
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.
Lane Cove North sits in the Municipality of Lane Cove and the City of Willoughby, postcode 2066. Bounded by the Pacific Highway, Epping Road, the Lane Cove River and the golf course, about 11 km north-west 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.
In the newer blocks this means the stack, and nothing done inside one apartment will change it.
Post-war pipe declines slowly. A season of worsening flow points at the pipe, not the fixture.
The suburb straddles the Municipality of Lane Cove and the City of Willoughby, and Mowbray Road is the divide.
A stack build-up in the newer high-density stock, which is most of the suburb at 70.8% flats. In the surviving post-war pockets the finding is the older one — roots into aged jointed pipe.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
Post-war veterans’ housing carries drainage of that era, largely jointed earthenware now around seventy years old. The towers are modern PVC. Because the suburb only separated from Lane Cove in January 2006, the boundaries of the two are not obvious from the street.
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 line before clearing it — in a suburb this dense a wasted visit to the wrong branch is the most common avoidable cost. Worth knowing early: Lane Cove North sits across two councils, so anything needing approval depends on which side of the boundary the property falls.
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 Lane Cove North 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 Lane Cove North and the rest of the Lower North Shore. More on emergency plumbing.
In the towers this is a building-level problem with a building-level fix: a jetting schedule on the stacks. Individual households contribute a small share of the load in a block of that size.
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 Lane Cove North:
Most often for one reason here: veterans’ housing beside new towers, in two council areas. A stack build-up in the newer high-density stock, which is most of the suburb at 70.8% flats. In the surviving post-war pockets the finding is the older one — roots into aged jointed 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 Lane Cove North 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 era of building it is, and which council. The suburb straddles the Municipality of Lane Cove and the City of Willoughby along Mowbray Road, so anything needing approval depends on the address rather than the suburb name. 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.
Lane Cove North is 70.8% 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 Lane Cove North covers the ownership rules in full.
Both, depending on the street. The suburb straddles the Municipality of Lane Cove and the City of Willoughby, with Mowbray Road as the divide. For clearing a drain it makes no difference; for anything needing council approval or a compliance certificate it decides who you deal with.
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.
