Blocked Sewer: What We Actually Do
Sewage moves through a separate pipe to stormwater, and it's the one job on this list that can't just wait for a convenient afternoon.
- Jetting and root cutting, shifting grease, solids and root mats out of the line
- Checking with the camera once we're done, so quiet doesn't get mistaken for clear
- Structural fixes, relining or repairing where the pipe has genuinely given way
- Checking the overflow relief gully is doing its job and nothing further along is wrong
- Working out why several fixtures are affected together, rather than treating each one separately

How to Tell You Need Blocked Sewer
Sewer trouble usually shows up as more than one symptom at a time, which is what separates it from a single blocked sink.
- Two or three fixtures acting up at once, not just the one you noticed first
- A smell hanging around the house that doesn't trace back to a single obvious source
- The gully outside your place bubbling or spilling over during normal use
- Every toilet in the property struggling, not just one, worth checking against our single-fixture guide first
- A shower or floor waste pushing water back up when the washing machine drains
- The same trouble spot flaring up again weeks after a clear, which a camera inspection will actually explain

Blocked Sewer in North Sydney Homes
North Sydney carries two very different generations of sewer pipe standing side by side on the same block, and that split shapes almost every job we run here.
The surviving Federation terraces and double-brick semis were connected with clay pipe from the 1830s township onward. That clay cracks with age and lets roots straight into the joints.
Newer stock tells a different story. High-rise towers around Miller Street run internal stacks and shared risers instead of a single house connection, so a blockage there can affect several units at once rather than one home.
Original clay drainage from that 19th-century housing fractures over time and lets in roots and debris exactly the way it has on Berry Street and blocks like it. On a shared building's stack, the same kind of blockage looks completely different from the outside: several apartments calling in the same afternoon instead of one house.

What Your Blocked Sewer Quote Depends On
The line and the blockage set the price, never a flat callout figure.
- Roots, grease or an actual structural failure in the pipe
- Depth and distance of the blockage from the nearest access point
- A single house connection, or one stack serving a whole block of units
- A jet clearing it for good, versus a reline or dig being the honest fix
- What's sitting over the line now, on blocks where paving went down after the pipe did
On streets like Berry Street, that clay-and-paving combination is often what turns a routine jet into a longer job, because reaching the cracked joint means working around whatever's since been built over it.
There's no call-out fee, and we don't charge to examine the line first. Approve the price, then we start. Book online and take $50 off.

The Process, and What It Typically Takes
A single blocked fixture is often sorted inside an hour once we're there. Root cutting or a full reline takes a fair bit longer, which we flag before picking up a tool.
- Get eyes on the pipe with a camera before touching anything
- Set the price there and then, so nothing's a surprise later
- Do the work the camera calls for, jetting, cutting or relining as needed
- Hand back a clear line, backed by the work for as long as it should hold

The Rules That Apply in NSW
NSW law requires sewer work to go through a licensed plumber or drainer, since a poorly repaired line can send sewage somewhere it was never meant to go.
Where that boundary sits depends on what you're living in. A terrace or semi has one connection running to the street.
Everything on your side of that connection, including the overflow relief gully (the grated outlet outside built to protect the bathroom first), falls to you as the owner, with the actual repair work falling to us.
A high-rise or walk-up building works differently again. The internal stack and shared riser serving multiple units are still private infrastructure, managed on the strata's behalf, right up until they join the street connection.
Either way, once a line crosses that connection point and runs under the road, it's Sydney Water's pipe, not ours or yours.
The tell is simple: if it's surfacing out at the street, or next door's having the identical problem at the identical time, that's Sydney Water's mains, which sits entirely outside what any plumber is permitted to touch.

What You Get When We Do Your Blocked Sewer
Sewage backing up isn't a job for guesswork, which is why we're on-site in 30 minutes guaranteed and answer the phone with a real licensed plumber, day or night, not a machine.
Our plumbers bring 35-plus years combined experience on the tools, enough to tell a single cracked joint apart from a shared stack affecting a whole building on sound alone.

Common questions
Your Blocked Sewer FAQs
Can blocked sewer be done without digging up the yard?
Usually. If the pipe's sound and roots or debris are the problem, jetting and cutting sort it without a shovel near your lawn. A genuinely cracked section is a different job, and we'll say so straight up.
Can you do blocked sewer in older homes with clay pipes?
Constantly. This suburb's earliest housing runs on original clay pipe, which cracks and lets roots in as it ages, so working on it is routine for us, not an exception.
What equipment do you use for blocked sewer?
A high-pressure jetter for grease, roots and solids, run through until the camera confirms nothing's left behind.
How much does blocked sewer cost in Sydney?
We can't give a number without seeing the pipe first. Once we've had a free look, you get one price to approve, with no charge just for us to attend.
How do I prepare before you arrive?
If sewage is close to the surface, stop running any tap feeding the affected fixtures, and keep kids and pets well clear of the gully outside. We'll manage the rest on arrival.
What are the signs I need blocked sewer?
Watch for two or more fixtures playing up together, a lingering smell indoors, or the gully outside spilling over. A single slow drain on its own is rarely the sewer line.
