Same-day drain clearing on the Lower North Shore.
Blocked sinks, toilets and main sewer lines cleared in Riverview — with a camera down the line afterwards, because a root that got in once will get in again.

Riverview is 97.5% separate houses on the northern side of the Lane Cove River at the head of Tambourine Bay, with Tambourine Bay Park on the foreshore and Marjorie York, Tambourine Bay and Burns Bay reserves nearby. Established native root systems sit against private drainage on most blocks, and the runs down towards the river are long. Roots into an aged joint a fair way from the house is the standard job here.
How people live in a suburb decides what blocks its drains. A high proportion of separate houses means most of the drainage here is private line running under gardens, which is exactly where roots find it.
Riverview sits in the Municipality of Lane Cove, postcode 2066. On the northern side of the Lane Cove River at the head of Tambourine Bay, nine kilometres 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.
Long runs to the river mean the problem is frequently nowhere near the fixtures reporting it.
With reserves on the boundary, root intrusion is the norm rather than the exception.
Roots grow. A drain that blocks at the same time each year has a live root mass in it.
A root mass at a joint well down a long run towards the river, with Tambourine Bay Park and the surrounding reserves supplying the roots. At 97.5% separate houses there is almost never a shared line to consider.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
The suburb grew around St Ignatius’ College, a three-storey sandstone building in Victorian Classical style, and the housing spans from that era onwards. Older properties drain through jointed earthenware; the institutional land in the middle of the suburb operates on a different scale entirely.
Roots have to come out before anything else can be assessed, and what happens after that depends on the state of the joint they came through.
The first move here. A cutting head removes the root mass and flow returns the same visit — but roots regrow through the same opening, so on its own it is a treatment, not a cure.
Shows the joint the roots came through and whether the pipe around it is sound. That is what decides between an annual clear and a repair.
A new liner cured inside the old pipe seals the joints the roots came through, removing the entry point without excavation.
Used here to flush out debris once the root mass is cut, and to show the joint clearly enough for the camera to assess it.
Clearing restores flow the same visit; the camera afterwards is what decides whether this is an annual event or a repair. On long runs under established gardens and reserve planting, relining seals the joint without excavating a length of pipe that would be expensive to reach and worse to reinstate.
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 Riverview property and we’ll tell you straight — including when the simple clear is the whole job.
If this line has blocked before, say so when you call. In Riverview a repeat is the signal that something is growing in the pipe rather than stuck in it, and that changes what needs to happen on the visit.
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 Riverview and the rest of the Lower North Shore. More on emergency plumbing.
An annual clear means roots are re-entering through the same opening every season. Sealing that joint ends the cycle, and on runs this long it usually pays back inside a few years.
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.
A cutter or jetter takes the mass out and restores flow, usually the same visit.
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 Riverview:
Most often for one reason here: long private runs to the river, under bushland reserve. A root mass at a joint well down a long run towards the river, with Tambourine Bay Park and the surrounding reserves supplying the roots. At 97.5% separate houses there is almost never a shared line to consider. 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 Riverview 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, while cutting tree roots from a line runs $400–$1,200. Root jobs sit at the higher end because clearing the mass is only half of it — the joint it came through is the other half. Those are market ranges rather than Voyager’s price list. How far down the block the fault sits, and what is above it. Long runs under established gardens and reserve planting are expensive to reach and worse to reinstate, which is what makes accurate location the main lever on the bill. 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. If the same line has blocked before, a camera is what tells you whether you are looking at an annual clear or a pipe that needs repairing. We would rather tell you it is fine than clear it twice.
Cutting the roots restores flow but leaves the opening they came through, so they return — usually within a year or two. Relining seals the joints from inside, which removes the entry point without digging up whatever sits above the pipe. An annual clear means roots are re-entering through the same opening every season. Sealing that joint ends the cycle, and on runs this long it usually pays back inside a few years.
Very. Riverview properties sit on the northern side of the Lane Cove River with long private runs down towards the water, so the fault is regularly a long way from the fixtures reporting it. That is exactly why we locate before we excavate — guessing the position on a run this long is what makes drainage work expensive.
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.
