Richard Harnett bought the original 108 acres in 1859 and opened a sandstone quarry at Mosman Bay in 1878; land development spread east from Milsons Point through the 1870s once the ferries ran, and Mosman became a municipality in its own right in 1893.
Rows of shops and Federation homes went up around the start of the 20th century, then multi-storey apartments arrived from the late 1950s — enough of them that the council brought in height restrictions. At the 2021 census 52.0% of occupied dwellings were flats or apartments, 34.9% separate houses and 12.0% semis or townhouses.
That history leaves two plumbing worlds side by side: apartment blocks on shared stacks and common-property lines, and Federation-era houses whose drainage may never have been replaced.
These jobs come up here more than they come up elsewhere. They follow from what Mosman is built from, when it was built, and what it sits on.
Mosman is almost exactly half apartments and half houses. A Federation house with original drainage and a 1960s block on a shared stack need completely different approaches, and they sit a few doors apart.
The shops and homes that went up around the start of the 20th century are still here, and on plenty of them the original house drain has never been replaced. Old jointed pipe is where repeat blockages start.
The peninsula’s coastal slopes and sandstone headlands mean private drainage often runs a long way downhill over rock, which is expensive ground to open up.
Most repeat blockages are a pipe problem, not a blockage problem. We look before we quote.
Every job below is handled by a licensed plumber, quoted before it starts, and covered by the lifetime labour warranty on eligible work.
Cleared properly, with a camera down the line to find out why it blocked.
Fix a cracked or root-damaged pipe without digging up the garden.
Burst pipes, sewage overflows and gas faults — 24 hours a day.
Repairs and replacements across electric, gas, solar and heat pump.
Find a hidden leak before anyone opens a wall or a slab.
Licensed gas work — appliances, new lines and suspected faults.
See what is actually in the pipe instead of guessing at it.
Isolate, repair and make good — usually the same day.
Get roof and surface water away from the house properly.
Describe what’s happening at your Mosman property and we’ll tell you straight — including when the simple fix is the whole job.
What a job looks like here depends on what the suburb is built from and built on. Start with how people actually live in it:
A peninsula between Sydney Harbour and Middle Harbour, with sandstone headlands at Bradleys Head, Georges Head and Middle Head, harbour beaches and steep coastal slopes.
Established gardens on the older streets, with mature root systems sitting alongside drainage laid generations ago.
Mosman sits in the Municipality of Mosman, postcode 2088. Work needing a compliance certificate is lodged the same way across the LGA.

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.
| Drains and pipes | |
|---|---|
| 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 |
| Repairs | |
| Leaking tap — washer or cartridge | $120 – $250 |
| Burst pipe, accessible | $250 – $500 |
| Burst pipe, underground | $800 – $2,500+ |
| Hot water, leaks and emergencies | |
| Hot water repair (element, thermostat, anode) | $150 – $550 |
| Hot water replaced, supplied and installed | $1,200 – $3,500 |
| Water leak detection | $250 – $600 |
| After-hours emergency attendance | $400 – $900 |
Hot water replacement above is supplied and installed — labour-only quotes look cheaper because they are not the same thing. And relining costs more per metre than digging, but that comparison ignores excavation, spoil removal and putting your driveway back, which is where dig jobs get expensive.
Voyager prices by the job, not by the hour, so the number you approve is the number you pay.
In Mosman, 52.0% of homes are flats or apartments — so on most jobs here the first question is not what is wrong, it is whose pipe it is.
Under section 106 of the Strata Schemes Management Act 2015 (NSW), the owners corporation has to maintain and repair common property. Section 153 puts the opposite duty on a lot owner: not to cause a nuisance or hazard to other lots.
For the 34.9% of Mosman properties that are freestanding houses, the line is simpler: you maintain the pipes from your property to the point of connection, and Sydney Water maintains the main.

Some problems wait for a booking. Burst pipes, sewage backing up, a hot water unit emptying itself into the floor and any suspected gas fault do not.
Voyager runs a 24/7 line for Mosman and the rest of the Lower North Shore. When you call, say what’s happening, where it is, and whether water, sewage or gas is involved — that’s what decides how fast someone needs to be there.
Before we arrive: turn off the affected supply if it’s safe to do so, and move what you can away from the water. Don’t pour drain chemicals down a blocked line — it makes the pipe unsafe to inspect and rarely clears the blockage.
Access splits with the housing. Apartment work runs through a building or strata manager; on the older houses the constraint is usually steep ground and sandstone between the street and the drainage line.
We assess access before quoting rather than discovering it on the day. On constrained sites it often decides which repair method is realistic, and that changes the price.
Storm season finds every drain that was never quite right. Better to know before it rains.
A short call is usually enough to tell whether it’s urgent, and what’s likely to be involved.
Where it matters, that means a camera down the line rather than a guess from the surface.
Priced by the job, not the hour. You approve it before anything starts.
You get told what caused it and whether anything else needs attention — including when the answer is nothing.
Voyager covers the whole Lower North Shore. These are the closest to Mosman:
24/7, including nights, weekends and public holidays — there is always someone on the line for Mosman. Arrival time depends on where crews are when you call, and genuine emergencies — burst pipes, sewage overflows, suspected gas — go ahead of booked work. Say what is happening when you call 0485 028 787 and you will be told honestly how long it will be.
Two plumbing worlds on the same street. Mosman is almost exactly half apartments and half houses. A Federation house with original drainage and a 1960s block on a shared stack need completely different approaches, and they sit a few doors apart.
Usually the owners corporation, if the pipe is common property. 52.0% of homes in Mosman are apartments, and under section 106 of the Strata Schemes Management Act 2015 the owners corporation maintains common property — which generally means any pipe serving more than one lot. A pipe inside your apartment can still be common property. We identify which it is before any work is authorised.
There’s no callout fee on eligible jobs, and quotes are free. You get a fixed price for the work before anything starts — priced by the job, not by the hour, so a job that takes longer than expected doesn’t cost you more.
Usually because the blockage was cleared but the cause wasn’t found. That history leaves two plumbing worlds side by side: apartment blocks on shared stacks and common-property lines, and Federation-era houses whose drainage may never have been replaced. A camera inspection shows whether you’re dealing with a one-off or a damaged pipe that will keep catching.
Usually yes, but access shapes the method. Access splits with the housing. Apartment work runs through a building or strata manager; on the older houses the constraint is usually steep ground and sandstone between the street and the drainage line. We work that out before quoting, because on constrained sites it decides which repair method is realistic.
Often not. Because Mosman is genuinely half apartments and half houses, the first thing worth settling is which kind of job it is: a common-property line the owners corporation is responsible for, or a private drain that is entirely yours. Relining repairs the pipe from the inside, which leaves driveways, paving and established gardens intact. Whether it suits your pipe depends on its condition — that’s what the camera inspection determines.
Across the Sydney market a simple blockage runs $150–$400, jetting a main line $250–$600, and pipe relining $450–$800 per lineal metre with most whole jobs landing between $4,000 and $10,000. Those are market ranges rather than Voyager’s price list. Mosman splits almost evenly between apartments and houses, and that decides the cost more than anything else. On a common-property line the owners corporation carries it and the cost is shared across lots; on a Federation house with original drainage you are the whole job. Steep sandstone also makes excavation dearer here than on flat ground. Voyager prices by the job, not the hour, and the price is agreed before work starts.
