Warrawee sits on the ridge between Turramurra and Wahroonga and is small — around 1,140 dwellings — but split, with large Federation garden blocks alongside a substantial 30.6% unit share. The garden blocks produce the classic problem: century-old drainage under planting that has had a century to find it. The unit stock produces the other one. Ridge-top position means the ground falls away on both sides.
How people live in a suburb decides what blocks its drains. A split like this one is why no assumption holds across the suburb — the same fault means something different depending which type of property it is in.
Warrawee sits in the Ku-ring-gai Council, postcode 2074. Ridge-top between Turramurra and Wahroonga.

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.
Large gardens mean a lot of private pipe, and the fault is rarely near the house.
The unit share here is higher than the leafy streets suggest.
Ridge-top position means which side of the ridge a property is on decides where the run goes.
Roots through Federation joints under large garden blocks, or a loaded stack in the 30.6% of dwellings that are units. For a suburb of only about 1,140 dwellings, Warrawee produces a genuinely mixed workload.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
Federation-era drainage under the large garden blocks — early-1900s earthenware, jointed, well past its design life. The apartment stock is much newer, so a small suburb still carries two quite separate systems.
Which of these a job needs depends entirely on the property, which is why we look before quoting.
Shows what caused the blockage and whether the pipe is damaged. The step that stops you paying twice.
Scours the pipe wall back to full bore rather than punching a hole through a build-up.
A cutting head removes the root mass itself. It restores flow, but roots grow back through the same opening.
A new liner cured inside the old pipe, sealing the joints roots came through. No excavation, so nothing above the pipe comes up.
Property type sets the method: jetting for a loaded stack, camera-then-reline for roots through a Federation joint. On the garden blocks the reinstatement cost after excavation is what makes the no-dig route the sensible one rather than the expensive 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 Warrawee property and we’ll tell you straight — including when the simple clear is the whole job.
Note which fixtures are affected and whether any neighbour has the same thing. In a suburb as mixed as Warrawee that is what narrows down whether the fault is yours alone.
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 Warrawee and the rest of the Lower North Shore. More on emergency plumbing.
On a Federation garden block, know where the line runs. In a unit, the building’s maintenance schedule does more than anything a household can.
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.
Jetting, cutting or a machine, chosen by what the line is doing — not by what is quickest to bill.
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 Warrawee:
Most often for one reason here: two suburbs’ worth of character in 1,140 dwellings. Roots through Federation joints under large garden blocks, or a loaded stack in the 30.6% of dwellings that are units. For a suburb of only about 1,140 dwellings, Warrawee produces a genuinely mixed workload. 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 Warrawee 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, jetting $250–$600, root cutting $400–$1,200 and a CCTV inspection $250–$550. Those are market ranges rather than Voyager’s price list. Which of the two Warrawees the property is in. The Federation garden blocks are priced around run length and reinstatement; the unit stock around building access and strata authorisation. 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 tells you whether this is maintenance or a repair being postponed. 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. On a Federation garden block, know where the line runs. In a unit, the building’s maintenance schedule does more than anything a household can.
Because 30.6% of its roughly 1,140 dwellings are units, which is higher than the leafy Federation streets suggest. Warrawee is genuinely two suburbs in one — large garden blocks with century-old drainage on one hand, apartment stock with shared stacks on the other. Which one you are in decides the cause, the method and who authorises the work.
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.
