A ridge suburb on the rail line north of Asquith, running along the edge of Ku-ring-gai Chase National Park.
83.9% separate houses with a modest 12.3% flats across 2,820 dwellings.
Predominantly private drainage lines, with a small band of unit stock near the station where drainage is shared.
These jobs come up here more than they come up elsewhere. They follow from what Mount Colah is built from, when it was built, and what it sits on.
Ku-ring-gai Chase runs the length of the suburb’s eastern side, putting bushland against a long line of residential blocks.
83.9% houses with a 12.3% band of units near the station — predominantly private drainage with a shared-line exception.
Sloping ground either side of the rail corridor means drainage rarely runs flat or short.
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.

Describe what’s happening at your Mount Colah 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:
On the ridge north of Hornsby, with the national park falling away to the east.
Ku-ring-gai Chase National Park runs along the eastern side of the suburb.
Mount Colah sits in the Hornsby Shire, postcode 2079. 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.
Mount Colah is 83.9% freestanding houses, so the ownership question here is usually straightforward — and worth knowing, because it decides who pays.
You are responsible for the wastewater pipes between your property and the point of connection to the network. Sydney Water is responsible for the main that carries waste away from multiple properties. Most of the pipe that can actually fail on a block like yours is yours to maintain.
On a detached block the fault can be anywhere along a long private run, so locating it accurately is most of the job. A camera and a pipe locator turn a whole-yard excavation into a targeted repair.
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 Mount Colah 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.
Reasonable street access along the ridge; properties on the national park side fall away steeply and are harder to reach equipment onto.
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 Mount Colah:
Voyager runs 24/7 for urgent work in Mount Colah. How fast depends on where crews are at the time, but genuine emergencies — burst pipes, sewage overflows, suspected gas — are prioritised over booked jobs. Call 0485 028 787 and describe what’s happening.
National park along the eastern flank. Ku-ring-gai Chase runs the length of the suburb’s eastern side, putting bushland against a long line of residential blocks.
In Mount Colah, where 83.9% of homes are freestanding, you are responsible for the wastewater pipes between your property and the point of connection. Sydney Water maintains the main. Because that point is not always inside your boundary, a Sewer Service Diagram is the reliable way to know where your pipework actually runs.
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. Predominantly private drainage lines, with a small band of unit stock near the station where drainage is shared. A camera inspection shows whether you’re dealing with a one-off or a damaged pipe that will keep catching.
Reasonable street access along the ridge; properties on the national park side fall away steeply and are harder to reach equipment onto. We work that out before quoting, because on constrained sites it decides which repair method is realistic.
Often not. National park on one flank and a mostly detached housing stock: root intrusion into private lines is the recurring job. 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. National park along one flank means root damage rather than simple blockages, and root-damaged pipe is a relining conversation rather than a clearing one. Voyager prices by the job, not the hour, and the price is agreed before work starts.
