Blocked Sewer: What We Actually Do
A blocked sewer needs speed and the right diagnosis, not just a snake down the nearest opening. Getting both right the first time is what stops a bad afternoon turning into a bad week.
- Run a camera to pinpoint the blockage before touching anything
- Clear roots, grease or solids from the main run
- Check the overflow relief gully and reset it if it's tripped
- High-pressure jet the line where clearing alone won't hold
- Reline or repair a section if the pipe itself has failed
- Confirm the fix on camera before we leave
When It Is Time for Blocked Sewer
Some signs point straight to the sewer line rather than a single fixture.
- Several fixtures gurgling or emptying sluggishly together
- The toilet rising when you run the shower or washing machine
- The overflow relief gully outside bubbling, overflowing or smelling
- A smell of sewage inside or near the house
- The lowest drain fixture in the house filling up first
- A blockage that returns within days of an earlier clear
One toilet on its own, with everything else draining fine, is a smaller job covered on our blocked toilets page. Want the exact cause confirmed before we start clearing anything? CCTV drain inspection handles that.
What We See in Double Bay Drains
Mature street trees along Knox, Cross and Bay Streets are doing more damage underground than most homeowners realise.
Their roots reach into the older clay and earthenware sewer lines running through the village's heritage blocks, following any hairline crack or loose joint they find. Once inside, they thicken every year and narrow the pipe further.
It's a pattern we see often enough near Gladswood Gardens that root-related sewer callouts there rarely surprise us.
Shared sewer lines add another layer here too. With apartments making up around 77% of Double Bay's housing, a single blocked stack can affect several units at once, which is exactly when speed and a clear answer for the strata committee both matter.
The Factors Behind a Blocked Sewer Quote
Sewer pricing depends on what the camera finds, not a flat rate for every callout. Two jobs that look identical from the street can turn out completely different once we're actually inside the line.
- How far into the property the blockage sits
- Whether it's roots, grease, solids or a structural fault
- Single-fixture backup versus a whole-house sewer issue
- Access to the boundary shaft or cleanout point
- Whether jetting clears it or the section needs repair
Roots from the street trees along Knox and Cross Streets often mean the jetting run has to go further than a straightforward blockage would.
That extra length shows up as time on the quote, never as a surprise fee afterwards. Either way: $0 call-out, a free on-site quote, $50 off when you book online, and the 10% seniors discount.
Whose Drain Is It, and What NSW Requires
One boundary decides who fixes what: your pipework up to the shaft on your property is yours to maintain, and it's exactly what our licence covers. Sydney Water owns and manages everything past that, out through the street mains.
Telling the two apart usually isn't hard. Sewage pooling out near the road, with more than one house in the same street affected, points to Sydney Water's network rather than anyone's private pipe. Our camera confirms which side of that line your problem actually sits on.
We stick to our side of that boundary, always. Anything genuinely in Sydney Water's territory gets referred on rather than touched.
The Process, and What It Typically Takes
Locate first. A camera confirms exactly where the blockage sits before anything else happens.
Clear it properly. Jetting, root cutting or a repair, whichever the line actually needs.
Reset the overflow relief gully. The grated drain outside that protects your bathroom gets checked too.
Prove it and back it. A final camera pass, backed by our lifetime labour warranty.
Most single-property jobs wrap up within the hour. A tougher root-cut main or a section that needs relining takes more time on-site, and we'd rather say that upfront than promise something we can't keep.
Why This Is a Job for Our Team
A sewer callout is the one job where speed matters as much as the fix itself, and that's where our team earns its keep.
Every call is answered by a real, licensed plumber, day or night, never a machine reading a script. That's the promise a burst or backed-up line actually needs.
Blocked Sewer Across Double Bay and Surrounding Areas
If the problem turns out to be a single fixture rather than the main line, our blocked toilets team can usually sort it the same visit. Want the cause confirmed before anything gets cleared? CCTV drain inspection does exactly that.
We're regularly working Double Bay and the surrounding Woollahra area, so a sewer callout here is never the first time we've seen this street.

Common questions
Your Blocked Sewer FAQs
What Double Bay homeowners ask us most when the sewer backs up.
How long does blocked sewer take?
A straightforward single-property blockage is usually sorted inside an hour of us arriving. Root-cut sections or a job that needs relining take longer, and we'll talk you through the real timeframe on-site rather than guess over the phone.
Do you offer blocked sewer in Double Bay on weekends?
We're on call weekends and public holidays the same as any other day. A sewer backup doesn't pick convenient timing, so our roster doesn't either.
Can I try to clear it myself first?
Not with a sewer blockage. Sewage is a health risk, and DIY tools can push the blockage further in or crack an already stressed pipe. This is one job worth calling a licensed plumber for straight away.
What are the signs I need blocked sewer?
Several fixtures acting up together, water rising in the shower when someone flushes, or the overflow relief gully outside starting to bubble. Any of these points to the main line rather than one isolated fixture.
Do I need a licensed plumber for blocked sewer?
NSW law requires it for sewer work, full stop. Our plumbers carry licence #275278C and the insurance to match, so you're covered on both counts.
Do you handle strata or commercial blocked sewer in Double Bay?
Yes. Strata blocks and commercial premises across Double Bay call us for shared sewer lines regularly, and we understand common property responsibility on top of the plumbing itself.
