Blocked Sewer: What We Actually Do
Fixing a sewer blockage means treating the whole line, not the nearest symptom.
Pinpointing where it's actually stuck. Not just where the water's showing up, but where the real hold-up sits.
Shifting roots and accumulated waste. Jetting or the electric eel reopens the line properly.
Handling junction and boundary-shaft trouble. These spots block differently to a straight run of pipe and need a different approach.
Chasing down repeat problems. If the same line keeps backing up, we find the actual reason instead of clearing it again on faith.
Two or three fixtures slowing down together is usually the clearest tell that this is a main-line issue.
Treating that as four separate small jobs instead of one sewer job almost always costs more in the long run, since the underlying blockage keeps sending problems back up through each fixture in turn.
When It Is Time for Blocked Sewer
Certain patterns point squarely at the main line rather than a single fixture.
- Two or more toilets, sinks or drains playing up around the same time
- A sewage odour that lingers outside or indoors without an obvious cause
- Gurgling that seems to travel through the house whenever water runs anywhere
- The lowest drain in the house, often a shower recess or floor waste, backing up first
- A toilet bowl rising when the washing machine or dishwasher empties out
- Several fixtures draining sluggishly at once, more than a plunger will fix
What We See in Mortlake Drains
Old trees on the original cottage allotments push roots into the suburb's older earthenware and clay drains, a recurring blockage cause.
Herbert Street's older blocks carry a good example of this, mature trees planted decades after the sewer lines went in, roots now working steadily into every joint they can reach.
Root growth doesn't pause once it's inside a pipe, so a line that drained fine last summer can start backing up abruptly once the growth reaches a certain point, sometimes with no warning at all before the first fixture slows down.
That's why these older streets tend to need proper root clearing rather than a quick flush that only buys a few weeks.
Blocked Sewer Pricing: What Moves the Quote
A short set of factors decides what a sewer job costs, all worked through with you on site.
- The number of fixtures involved and how far the fault sits from the house
- Whether it's roots, a collapsed length, or straightforward build-up causing it
- Access to the line, including whether a shaft near the boundary needs opening
- What actually shows up once the camera's had a proper look
- Whether a single clear will hold, or root cutting is genuinely needed
Given how many mature trees sit close to the older lines around Herbert Street, we generally know to expect root work before we even arrive, so it's rarely a surprise addition part-way through.
Diagnosis comes first, then a fixed figure before work begins, with same-day attendance where the job allows.
Our Blocked Sewer Process, Start to Finish
See what's happening. Camera down the main line before anything else, so the cause is known, not guessed.
Open the line up. High-pressure water jetting or the electric eel shifts the blockage clear.
Fix what caused it. Root cutting, a targeted repair, or simply flushing the line through, matched to the actual finding.
Confirm and pack up. We check the whole system is flowing again and leave things as tidy as we found them.
Straightforward sewer jobs usually finish within a few hours of arriving. Root cutting or a repair extends that timeframe, and we'll flag that honestly once we've actually seen inside the line.
Licensed, Insured and Accountable
Sewer work sits squarely inside licensed plumbing under NSW law, not a job for trial and error.
Getting it wrong on a main line risks sending the same problem straight back through every fixture connected to it.
Both water and gas licensing fall under Lic #292427C, covering everything a sewer job involves.
As a rule of thumb, the pipework belongs to the homeowner right up until it ties into the network, and Sydney Water takes over from that tie-in point onward.
We'll help work out which side a fault sits on, but the street-main side stays Sydney Water's to handle, never ours.
If the camera shows the trouble is genuinely on their side of that connection, we'll say so plainly rather than take on work that isn't ours to do.

Where it turns out to be one damaged stretch rather than the whole line, blocked drain repair picks up that job instead.

Your Blocked Sewer FAQs
Straight answers to what Mortlake homeowners ask us most about blocked sewer lines.
Who is responsible for a blocked sewer, me or Sydney Water?
Generally speaking, everything from your house out to where the pipe meets the network is on you, and Sydney Water takes it from that junction into the street. It's worth confirming with them directly if the exact boundary matters for your situation.
What warranty comes with blocked sewer?
Every sewer job we finish is backed by a lifetime labour warranty, regardless of scale.
Can tree roots be removed from a drain without digging?
Usually, yes. Cutting the roots back and jetting the line clears them out, and a follow-up camera pass confirms the pipe's condition before we sign off.
Do you offer blocked sewer after hours or on weekends?
Around the clock. A sewer backing up on a Sunday night gets exactly the same response as one on a Wednesday afternoon.
How much does blocked sewer cost?
It depends on the number of fixtures involved and the underlying cause once we've had a proper look. We assess it in person, then settle on a figure before anything starts.
Do you put a camera down the drain before you clear it?
On every sewer job, yes. With several fixtures involved there's usually more than one possible cause, so seeing the pipe first stops us guessing.
