What Our Blocked Sewer Work Covers
Sewer work means the wastewater side of the system, everything carrying it away from toilets, showers and kitchens.
- Main line clearing where multiple fixtures back up at once.
- Root intrusion repairs on sewer pipe that's cracked or joint-damaged.
- Overflow relief gully attention, the outdoor grate doing its job when the line's overloaded.
- Camera diagnosis to confirm whether it's a clear, a repair, or both.
- No-dig relining on damaged sewer sections, where the pipe allows it.
- Boundary shaft work on the section of pipe between your house and the street connection.
When It Is Time for Blocked Sewer
Some signs mean call now, not later, because sewage backup gets worse fast.
- More than one toilet, shower or sink is backing up together.
- The overflow relief gully outside is overflowing or bubbling.
- A sewage smell has appeared around the yard or under the house.
- Toilets gurgle when you run the washing machine or shower.
- Water rises in one fixture when you flush another.
- Neighbours nearby have mentioned the same problem lately.
If only one fixture is affected, our blocked toilets page covers the narrower, less urgent case.
Don't run more water down an already-struggling line hoping it clears. Turn off what's feeding the fixture, stop using the toilets and drains you can, and get someone qualified to look before it spreads further through the house.
What We See in Collaroy Drains
A lot of Collaroy's housing dates from the mid-20th century, the brick and fibro dotted up the slope behind the beach. Underneath it, the original earthenware sewer pipe is now well past its intended life.
Those clay joints are where root intrusion starts, and it's the single biggest driver of the blocked sewer calls we get out this way.
Florence Avenue and the older streets nearby sit on that same vintage of pipe. Where a private line has failed, we can usually pinpoint it fast because the pattern repeats block to block: hand-jointed clay, decades of tree growth, and a root finding the gap eventually.
Newer builds closer to the beachfront strip tend to be on modern pipe and see far fewer of these calls. It's the older slope housing doing most of the heavy lifting on this list.
What Affects the Cost of Blocked Sewer
A handful of things decide what a sewer job actually costs, and none of it is a guess.
- Whether it's one blocked fixture or the whole main line.
- How deep the affected section runs and what's above it.
- Roots versus a genuine crack or collapse.
- Whether relining is realistic or the section needs digging up.
On Florence Avenue's older blocks, tree-lined nature strips often mean root cutting is part of the job before we can even assess the pipe properly, and that gets accounted for early. Either way, you're covered by $0 call-out, no charge to look, and a single number to approve first.
Our Blocked Sewer Process, Start to Finish
Assess urgency first. Multiple fixtures backing up together gets priority dispatch, on-site in 30 minutes guaranteed.
Camera the line. We find the exact cause before deciding what the fix needs to be.
Clear or repair. Jetting and root-cutting for a clean; relining or excavation where the pipe's damaged.
Confirm it's done. Camera proof the line is running clear, then we pack up.
What NSW Requires for Blocked Sewer
The private drain, everything from the house to your boundary shaft, is on you as the owner, and that's the stretch we work on. Sydney Water takes over from the mains onward, everything downstream of that shaft.
NSW rules mean this work sits with a licensed plumber, and our licence #275278C covers it.
Telling the two apart is usually simple. If it's just your place affected, it's private; if neighbours nearby have the same issue and there's sewage surfacing at the street, that's a Sydney Water mains problem to report to them, not us.
The Difference on a Blocked Sewer Job
We treat a sewer callout as urgent because it is. 15,000 Sydney families have called us for exactly this, and the response doesn't change based on how unpleasant the job sounds on the phone.
Book online and the current $50 offer comes off the top. We've also picked up Best & Brightest recognition three separate years, judged on jobs like this one.
Related Work and Surrounding Areas
Where the camera turns up a crack or a collapse, blocked drain repair is the follow-on job, and a single stubborn toilet rather than the whole line points to blocked toilets instead.
Collaroy and the surrounding Northern Beaches area get the same urgent response, Narrabeen and Dee Why included, whatever hour the call comes in. Cromer and Brookvale homes further inland see the same clay-pipe pattern and the same fixed-price terms.

Common questions
Your Blocked Sewer FAQs
What tools get used to sort out a blocked sewer?
Locating the fault comes first, on camera, since roots, grease and a collapsed joint all need different handling. Buildup gets jetted off the pipe wall; a straightforward clog is often quicker with an electric eel.
Is a blocked sewer something I can sort myself?
One fixture on its own, maybe a plunger's worth trying. Several fixtures going at once is the main line, and that's not something a plunger or a bottle of drain cleaner is going to fix.
The last plumber cleared it and it's blocked again, why?
Clearing shifts the blockage, it doesn't mend a cracked pipe or a joint that's already given way to roots. Without a camera confirming the actual cause, the same spot just fills back up on its own schedule.
Does fixing a blocked sewer mean digging up the garden?
Not in most cases we see. A damaged section of sewer pipe usually relines from the inside, leaving your lawn and paving alone. Digging comes into it only where the pipe has properly caved in.
How much does blocked sewer cost in Sydney?
It depends on depth, access and what's actually causing the blockage, so we won't quote a figure sight unseen. What's fixed is the process: $0 call-out fee, a free on-site look, and one price you approve before we start.
Do you offer blocked sewer in Collaroy on weekends?
Yes, weekends included. Sewage doesn't check the calendar, so we run 24/7, 365 days a year, with a real licensed plumber answering the phone every time.
