Hunters Hill was settled from 1835 and proclaimed a municipality in 1861, and it holds around 650,000 square metres of parks and reserves. Old pipe under mature canopy is the textbook condition for root intrusion, and it is the dominant cause here by a distance. What makes it harder than elsewhere is what sits on top: much of the suburb is heritage listed, and the sandstone houses the Italian stonemasons built from 1847 are not structures anyone excavates casually.
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.
Hunters Hill sits in the Municipality of Hunter’s Hill, postcode 2110. On the peninsula that separates the Lane Cove and Parramatta Rivers. The Aboriginal name for the area is Moocooboola, meaning ‘meeting of waters’.

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.
Very old pipe fails where it has failed before. A recurring location is structural, not bad luck.
Under this much canopy, root material in the debris is the norm rather than the exception.
Sandstone country shifts, and a century-old mortared joint reopens when it does.
Roots through a mortared joint in pipe that may be over a century old, often with two or three later generations of pipe spliced into the same run. The camera regularly finds more history than anyone expected, which is precisely why it goes down first here.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
The oldest housing stock Voyager works on. Drainage that has been altered, extended and patched across a century and a half rather than laid once — so a single property can carry three or four generations of pipe, joined wherever someone added a bathroom. Assume nothing about what is under it.
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.
This is the strongest case for no-dig repair anywhere on the North Shore. Locating the fault precisely, clearing it, then relining from inside keeps the work entirely within the existing pipe — which is what protects a heritage garden, a sandstone path or a listed streetscape that cannot be reinstated at any price.
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 Hunters Hill 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 Hunters Hill 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 Hunters Hill and the rest of the Lower North Shore. More on emergency plumbing.
Know where the line runs before anything is planted, paved or extended over it. On a heritage property that single piece of information is worth more than any amount of maintenance, because the alternative is lifting something irreplaceable.
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 Hunters Hill:
Most often for one reason here: the oldest drainage on the North Shore, under heavy canopy. Roots through a mortared joint in pipe that may be over a century old, often with two or three later generations of pipe spliced into the same run. The camera regularly finds more history than anyone expected, which is precisely why it goes down first here. 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 Hunters Hill 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. What sits above the pipe, and it is not close. Heritage listing and 1840s sandstone mean excavation is restricted, expensive to make good, and sometimes not permissible — so the money goes into locating the fault accurately and repairing from inside. 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. Know where the line runs before anything is planted, paved or extended over it. On a heritage property that single piece of information is worth more than any amount of maintenance, because the alternative is lifting something irreplaceable.
In most cases yes, and in Hunters Hill that is usually the whole point. Relining cures a new pipe inside the existing one through an existing access point, so sandstone, established gardens and listed streetscapes stay untouched. Where excavation genuinely cannot be avoided we say so before you commit to anything.
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.
