What We Handle Under Blocked Sewer
Not every blocked sewer looks the same, and the right fix depends on which kind you've got:
- A single toilet or floor drain playing up while everything else in the house runs fine
- Every fixture backing up together, the surest sign the main line itself is choked
- The overflow relief gully doing its job, that grated drain outside surcharging as designed
- Roots working into a jointed line, thickening year on year until they choke it
- Grease and solids narrowing the pipe until nothing moves through freely
Diagnosing which of these applies comes before we quote. A single stuck toilet and a full-line jet are two entirely different jobs.
When It Is Time for Blocked Sewer
Certain signs mean pick up the phone rather than wait it out:
- Two or more fixtures backing up or gurgling in the same stretch of time
- A sewage smell reaching inside the house, beyond just the yard near the gully
- The overflow relief gully surcharging out onto the ground
- Water rising in one fixture the moment a different one gets used
- Drainage slowing across the whole house, not just at a single sink or toilet
- A backup that clears, then returns within days, worth ruling out with CCTV drain inspection
Why Neutral Bay Properties Call For This
Established trees along Neutral Bay's older streets send their roots hunting for moisture, and a sewer line is exactly where they find it.
Pre-1940 stock here mostly runs on jointed clay and earthenware, and Yeo Street sits right in the middle of that older run, where we see root intrusion cause more blockages than anything else.
A joint doesn't need much of a gap for a root to find its way in. From there it just keeps thickening, season after season, until a house that's drained fine for years backs up with almost no warning.
What Affects the Cost of Blocked Sewer
A sewer quote moves on a specific set of factors, and we run through them before pricing:
- Single fixture, or the whole property backing up
- Depth and location of the blockage, and what's causing it
- Access at the boundary shaft versus a line running under paving or a driveway
- Whether jetting alone clears it or the pipe needs repair too
- Strata common property versus one dwelling's own line
The older jointed sections around Yeo Street show how much cause changes cost. Roots choking an earthenware joint usually clear with jetting alone, but a joint that's actually cracked under that same root pressure needs the pipe fixed, not just the blockage cleared.
What matters in practice is the model behind the number: $0 call-out, a free on-site look and one figure you approve before anything starts.
Most Neutral Bay addresses are units rather than standalone houses, so shared sewer stacks come up constantly in this line of work. A backup in one apartment can trace back to a section serving several floors above or below it, which changes both who's affected and who ends up covering the fix.
Our Blocked Sewer Process, Start to Finish
- Assess the scope. We work out fast whether it's one fixture or the whole line.
- Camera and locate. A drain camera finds the exact cause before anything is quoted.
- Clear it properly. Jetting, root cutting or repair, whichever the camera shows is needed.
- Prove it's clear. A final camera pass, backed by our lifetime labour warranty.
The Rules That Apply in NSW
Sewer drainage work must be carried out by a licensed plumber in NSW, without exception.
Here's how the boundary actually works. Everything from your house to the property boundary shaft is yours to maintain as the owner.
Past that shaft sits Sydney Water's mains network, and fixing that side is on them, not you.
Telling the two apart usually comes down to your neighbours. Sewage surfacing at the street with the same trouble next door points to Sydney Water's mains.
A problem confined to just your property is almost always sitting inside your own boundary instead.
The Difference on a Blocked Sewer Job
A blocked sewer at an odd hour is exactly when the named awards and the paperwork stop mattering and the response does.
We guarantee on-site in 30 minutes, and a licensed plumber answers the phone 24 hours a day, 365 days a year. Not a call centre reading from a script.
That's part of why over 1000 Sydney homes have left us five-star reviews. A blocked sewer at 2am is the moment that reputation actually gets tested.
Servicing Nearby Homes Too
A blocked sewer often turns out to be one symptom of a bigger issue once we're on-site.
Single fixtures playing up point instead to blocked toilets, and if you'd rather confirm the cause before booking a clear, CCTV drain inspection settles it on camera first.
We're servicing Neutral Bay and the wider North Sydney area, including Kirribilli, North Sydney and Crows Nest, on the same terms.

Common questions
Your Blocked Sewer FAQs
Straight answers to what Neutral Bay callers ask about a blocked sewer.
How long does blocked sewer take?
A choke on one fixture is usually gone within the hour. A root-cut line or a full-property backup runs longer, and we'll tell you which situation you're in before starting.
What warranty comes with blocked sewer?
Lifetime labour cover on every sewer job. If it fails again, we're back at no cost to you.
Why does my drain keep blocking after other plumbers clear it?
A clear that keeps failing usually means the sewer line itself has a fault nobody's found yet, whether that's a root, a crack or a misaligned joint.
Do you handle strata or commercial blocked sewer in Neutral Bay?
Often. Shared sewer stacks in Neutral Bay's apartment blocks mean strata plumbing, and we work with building managers so the right party is billed.
Can I try to clear it myself first?
A plunger can help on one toilet. Once several fixtures are backing up together, stop, because that points to the main line and a plunger won't reach it.
Who is responsible if the blockage is in the sewer main?
Everything from your property boundary to the house is yours to maintain. Past that boundary shaft, it belongs to Sydney Water, and their mains are their responsibility, not yours.
