Terraces with no side access, steep blocks and lower levels that sit below the sewer. We bring gear that actually fits the property, and we camera anything that has happened before.

Two things about this suburb decide almost every drain job, and neither of them is about what went down the sink.
The first is the housing. These streets were subdivided for terraces from the 1860s onwards, and a terrace has party walls on both sides. There is no side path, so there is no way to walk a jetter or a camera reel to the back of the property. Everything comes through the front door and down the hallway. That is not a complaint, it is a planning consideration, and a plumber who turns up with a trailer-mounted machine and no way to reach the rear has wasted your morning.
The second is the slope. The ground drops hard toward the harbour through Kirribilli, McMahons Point, Lavender Bay and Waverton, and that has two consequences. Lower levels can sit below the sewer main, so those fixtures rely on a pump rather than gravity and flood when the pump fails. And stormwater on a slope moves rather than ponds, so a blocked pit sends water somewhere, usually under the house or onto whoever is downhill.
Underneath both is the age of the pipework. Original cast iron narrowing from the inside, and earthenware joints that a century of established gardens have found.
Tell us whether there is side access to the rear. On a terrace there usually is not, and knowing that before we load the van is what makes it a one-visit job.
A terrace is sealed on both sides. The only route to the rear is through the house, and that decides what equipment can reach a line and what it costs to get there.
So the practical question here is not what is wrong with the drain. It is how anybody reaches it, and that is worth establishing on the phone.
It also means anything carried through has to be carried back out, which is a real consideration on a job that produces mess.
On the steep harbour-side blocks, a converted basement, a garage turned into a room or a lower-level bathroom can sit below the level of the sewer it has to reach.
Those need a pump rather than gravity, and a pumped fixture fails completely and without warning rather than slowing gradually.
If you have one, that is worth mentioning when you ring, because it changes the diagnosis entirely.
Flat suburbs get ponding. Here the water has momentum, so a blocked pit or an overshooting gutter sends water into the building or onto the neighbour below rather than into a puddle.
That makes stormwater maintenance more consequential on these streets than it is on level ground.
Pits and downpipes are worth clearing on a schedule rather than on appearance, before the wet months rather than during them.
The terraces still run a great deal of original cast iron. It corrodes from the inside and loses bore steadily over decades with nothing visible from outside.
So the line is not only accumulating material, it has less room for it than it started with, and both effects compound.
That is why a building can go from occasional trouble to regular trouble without anything having obviously changed.
Terraces frequently share drainage, or run a line along or under a neighbour's property, and almost nobody knows which arrangement they have.
So a blockage can be caused upstream by a household with no symptom at all, and a repair may sit under somebody else's courtyard.
A camera survey settles it, and on a shared line it is worth doing before any conversation with a neighbour starts.
A single slow basin is that fixture and its trap. Several, or the lowest fixture in the house, is the main line out telling you so.
Once is an event. Three times in a year at the same point is a defect describing itself, and on a shared line the occurrences may move between houses.
Keep a rough note of the dates, and ask the neighbours. Both are genuinely useful here.
A sewer blockage is indifferent to the weather. Trouble that only arrives in a downpour and eases when it stops is the stormwater side.
On a steep block that distinction matters more, because stormwater moving fast does damage that stormwater sitting still does not.
Saying which one you have gets the right equipment to a street where parking is its own problem.
Roots do not break sound pipe. They enter at an opening the ground has given them, and jointed lines of this age offer one every metre.
Front gardens on these terraces are small and the street trees are mature, so a tree is frequently very close to the line.
The durable repair removes the opening rather than this season's growth, and it does not ask anybody to take a street tree out.
Wipes remain the largest single cause of what we cut out of drains, and on cast iron that has already lost bore there is less room to give up.
Kitchen fat is the slower version, and on a shared line it arrives from more than one kitchen.
So both of the ordinary causes have more effect here than they would in a modern house on its own line.
Whether the line is restricted by material, by corrosion or by a defect, where it runs, and whether anybody else is on it. All four are genuine questions here.
The recording is yours whatever it shows, and on a shared line it is worth sharing with whoever else is connected.
It is also the only way to establish a route that has never been documented anywhere.
Quoted at a fixed price before it starts. These are indicative 2026 ranges. Access moves the figure here more than in most suburbs, and we will tell you that up front rather than discovering it at your front door.
Hand tools or an electric eel through an existing access point. Most jobs land here.
High-pressure water where an eel will not do it, with gear that fits through a terrace.
Down the line with the footage handed over. The right call on a second blockage.
Mechanical cutting back to clean pipe, then a camera pass to show what is left.
Issued with the footage. What you need for a neighbour, an insurer or a sale.
Terrace or freestanding, side path or not, and how far down the block the drain sits. That decides which machine goes on the van.
On a terrace the gear comes through the hallway, so drop sheets go down first and the hoses are managed rather than dragged.
A first blockage gets cleared. A repeat gets the camera, because on century-old cast iron the question is how much bore is left.
You watch it on the screen, we mark where the fault sits on the surface, and the report goes to you with the invoice.
Stop using every fixture on that line. If it is only the lower level, check whether you have a pump and whether you can hear it, that changes the job completely.
Call 1300 381 569Yes, and it is most of what we do here. A terrace has party walls on both sides, so there is no path to the rear. Everything comes in the front door, through the hallway, and out the back, which means drop sheets, careful reel handling and a bit more time. It is worth saying when you book, because it changes which machine we bring: a large trailer jetter is no use if it cannot reach the back, and a compact unit that can is the difference between clearing it today and coming back.
On a block this steep that is often not a blockage at all. Where a lower level sits below the sewer main, those fixtures cannot drain by gravity and rely on a pump-out system. When the pump fails or its float sticks, the lower room fills while everything above it behaves perfectly. Check whether you have a pump and whether it is running before assuming the line is blocked, because the two problems have completely different fixes and prices.
On a slope, stormwater does not pond and wait. It arrives fast, and a blocked pit or downpipe redirects it, usually under the house or into whatever sits downhill, which on these streets is frequently the neighbour. That makes a blocked stormwater pit here more urgent than it would be on flat ground, and it is a genuinely worthwhile thing to clear before a storm rather than during one.
Age and roots, in that order. The terraces here date from the 1860s onwards, and many still run original cast iron above ground and earthenware below. Cast iron corrodes inward, so the usable bore narrows year by year while the pipe looks sound from outside. Earthenware joints open enough for roots from the mature planting these streets have had well over a century to grow.
Common in this housing and worth establishing before anyone pays. Where a line serves more than one property, responsibility usually follows the pipe rather than the postcode, and the camera is what settles where the fault actually sits. We put the finding in writing. It is a much easier conversation with a neighbour when there is footage rather than two opinions.
On soap or grease in a basin, occasionally. On what blocks drains here, roots, corroded cast iron, a collapsed section, no. They generate heat and sit against the obstruction rather than passing through it, which is particularly bad for old cast iron. They also make the job less safe for whoever comes next. If you have already used one, tell us when you call.
Most clears through an existing access point are $150 to $400, and a stubborn line needing the jetter is $400 to $700. A camera inspection is $250 to $450 with the footage included. Access is the thing that moves it here: a terrace with no side path, or a property where the drain sits down a steep set of steps, takes longer than the same job on a flat block with a driveway. We will say so before we start rather than after.
Tell us whether it is a terrace and whether there is any way to the rear other than through the house. That one answer decides what we bring.
Fixed price agreed before we start, and the footage handed over on anything we recommend.
