Same-day drain clearing on the Lower North Shore.
Blocked drains cleared in Cammeray — starting with whether it is a blockage at all, because stormwater and ground water look identical from the surface.

Cammeray’s development was held back by its own terrain — steep ground across 1.5 square kilometres, with Flat Rock Creek and gully country cutting through the eastern side. When the estates finally went in through the 1920s, drainage had to follow that topography, and it still does. Water moving through gully ground finds cracked joints in century-old pipe, and the result is as often ingress and damp as a straightforward blockage.
How people live in a suburb decides what blocks its drains. Housing type matters less here than what the ground is doing, but it still decides whether a fault is yours alone or shared with the building.
Cammeray sits in the North Sydney Council, postcode 2062. At 87 metres across 1.5 square kilometres, with steep terrain that held back early development, and frontage to Long Bay and Middle Harbour.

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 gully ground a line that misbehaves after rain is usually taking water in, not blocked.
Water escaping a cracked joint on a slope shows as moisture long before flow is affected.
1920s earthenware fails slowly at the joints, and that is what a season of worsening flow looks like.
As often water getting into the line as anything blocking it. Gully ground either side of Flat Rock Creek moves, and a 1920s mortared joint that shifts becomes an entry point. Where it is a genuine blockage, it is usually roots that came in the same way.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
The interwar estates carry original drainage in many cases — jointed earthenware laid in the 1920s, now a century old and sitting in ground that moves. The 59.6% of dwellings that are flats bring the other pattern, with shared stacks blocking on fat and wipes rather than anything the ground does.
The first job is working out which system is actually failing, so the camera tends to come before the machine.
The starting point here rather than the finish, because stormwater ingress and a true blockage look identical from the surface.
Useful for clearing silt and debris washed into a line, which is a different problem from something stuck in it.
Seals a cracked or open-jointed section so ground and storm water stop getting in — which is the actual fault in a lot of these jobs.
Only where the camera has actually found roots, which on these blocks is less often than people assume.
Establishing whether water is getting in or out comes before clearing anything, because on gully ground the symptoms of ingress and blockage overlap almost completely. Steep terrain also limits machine access on a lot of these blocks, which is what makes sealing a joint from inside the practical repair rather than the premium one.
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 Cammeray property and we’ll tell you straight — including when the simple clear is the whole job.
Note whether it is raining, or was recently. In Cammeray that single detail separates a blockage from a stormwater or ingress problem, and the two are fixed completely differently.
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 Cammeray and the rest of the Lower North Shore. More on emergency plumbing.
On gully ground the useful habit is noticing weather patterns. A line that only misbehaves after rain is reporting a fault worth finding while it is still small.
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.
Sewer, stormwater or ground water — they look alike from the surface and are fixed completely differently.
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 Cammeray:
Most often for one reason here: gully country under interwar estates. As often water getting into the line as anything blocking it. Gully ground either side of Flat Rock Creek moves, and a 1920s mortared joint that shifts becomes an entry point. Where it is a genuine blockage, it is usually roots that came in the same way. 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’.
24/7, including nights and weekends — the line for Cammeray and the rest of the Lower North Shore is always answered. Severity sets the order rather than booking time: if sewage is surfacing or a main line has stopped, say so when you call and it goes ahead of routine work.
Across the Sydney market a simple blockage typically runs $150–$400 and a CCTV inspection $250–$550. Here the inspection often comes first, because paying to clear a line that was never blocked helps nobody. Those are market ranges rather than Voyager’s price list. Whether the fault is ingress or obstruction, and how reachable it is. Steep ground rules machine access out on a lot of these blocks, so the realistic comparison is between hand excavation and a no-dig repair rather than between digging and not digging. We price by the job, not the hour, and you approve the number before anything starts.
Rarely, and it can make things worse. Caustic product does not shift a root mass or a collapsed section, it sits in the line where it is a hazard to work on, and against an aged earthenware joint it does the pipe no favours. If a chemical has already gone down, tell us before anyone opens the line.
If it is a genuine one-off — something went down that shouldn’t have — clearing it is the whole job. Here it is often the first step rather than the last, because the symptoms of stormwater ingress and a true blockage are indistinguishable from above. We would rather tell you it is fine than clear it twice.
Cammeray is 59.6% 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 Cammeray covers the ownership rules in full.
Usually that water is entering the line rather than something blocking it. Cammeray’s gully country either side of Flat Rock Creek moves enough to open joints in interwar pipe, and a cracked line takes stormwater and ground water in. Clearing it will not help for long — sealing the opening will.
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.
