Blocked drain costs in Sydney run from about $150 for a simple fixture clear to $800 or more once you are into a main sewer line. Most straightforward jobs land between $150 and $400 during business hours. Roots in an older clay line, poor access, or an after-hours call-out all push it up, and this guide explains exactly how much and why.
Quick cost snapshot
- Simple fixture clear: $150 to $300
- Toilet or kitchen line: $180 to $400
- Main sewer line clear: $300 to $800 and up
- After hours: add 30% to 60%, and up to double on a public holiday
R&G charges a $0 call-out fee, so you are never billed simply for us turning up and looking.
The Short Answer: The Price Band
For a standard residential blocked drain in Sydney, cleared during business hours with an electric drain machine, the market sits between $150 and $400. That covers the plumber’s time, the machine, and clearing a single accessible line.
Above that band, you are usually paying for one of four things: heavier equipment, more depth, tree roots, or the clock. Below it, you are usually not getting a complete job, which is the subject of the last section.
One number worth knowing before you ring anyone: a job that costs around $300 on a Tuesday morning commonly runs $600 to $900 as a Sunday night emergency. Same blockage, same pipe. If it can wait until morning, waiting is the single biggest saving available to you.
What Actually Changes the Price
Four variables do almost all the work. Any quote that does not account for them is a guess.
Access. Whether there is an inspection opening the plumber can actually use. A property with a clear boundary shaft is a quick job. A line with no accessible opening, or one buried under decking, paving or a garden bed, adds labour before any clearing starts. Older Sydney suburbs with tight side passages, long runs and raised floors are consistently the more expensive jobs for this reason alone.
Depth and length of run. A blockage two metres in is a different task from one twenty metres down at a metre and a half deep. More pipe means more time and, past a point, different equipment.
Roots versus debris. Fat, paper and debris come out with a standard machine. Roots need cutting, and cutting roots is slower, harder on equipment, and rarely a one-visit fix if the pipe itself has failed. This is the single largest step up in price, and it is far more common in homes built before about 1970, where the sewer line is vitrified clay with joints that were never fully watertight.
The hour and the day. After-hours rates in Sydney typically run 30% to 60% above standard, and late-night or public holiday attendance can reach double. This is standard practice across the trade, not a mark-up unique to any one company.
Price by Job Type
These are typical 2026 Sydney market ranges. They are what the trade charges across the city, not a quote for your property, and the whole point of the section above is that your job will sit somewhere inside the range for identifiable reasons.
| Job | Typical Sydney range | What it involves |
|---|---|---|
| Standard machine clear Sink, shower or basin |
$150 to $300 | Electric drain machine or auger on an accessible branch line |
| Toilet or kitchen line | $180 to $400 | Slightly higher than a basin: different access, and kitchen lines usually mean grease |
| Main sewer line clear | $300 to $800+ | Heavier equipment, more depth, more labour |
| CCTV drain inspection | $250 to $700 | Camera run of the line, depth and position marked. Often bundled with a clear rather than billed separately |
| Hydro jetting | $250 to $600 | High-pressure water scours the pipe wall back to full bore. The right tool for grease |
| Root cutting | $350 to $1,200 | Wide range because root volume and run length vary enormously |
| Sectional or patch relining | $2,500 to $5,000 | Repairs an isolated damaged section, typically half a metre to three metres |
| Full line relining | $4,000 to $10,000 | A full run, commonly $400 to $800 per metre plus a setup charge |
| Excavation and replacement | $2,500 to $15,000+ | Digging, then reinstating whatever was above the pipe. Usually the last resort |
The jump from clearing to relining is the one that surprises people, and it is worth understanding why it exists. Clearing restores flow through a pipe that still works. Relining rebuilds a pipe that has structurally failed. They are not competing options; one is maintenance and the other is a repair.

Does R&G Charge a Call-Out Fee?
No. There is no call-out fee, which means you are not billed for the trip, the assessment or the conversation. You pay for work, and you agree on the price for that work before it begins.
This matters more than it sounds on a blocked drain in particular, because the honest answer on site is sometimes that you do not need us. A dry floor waste trap, a cistern that is not filling, a dishwasher hose loop that has slipped: those are ten-minute conversations, not invoices. A call-out fee turns every one of those into a charge, which is exactly the wrong incentive.
What Should Be on the Quote Before Work Starts
Five things. If any are missing, ask.
- A fixed price, not an hourly rate. Hourly billing on a drain puts the risk of a difficult job entirely on you.
- What the price covers, and what it does not. Specifically: Is a camera included, and is root cutting included if roots are what is found?
- What happens if the pipe turns out to be damaged? The answer should be that work stops, you are shown the problem, and you approve a separate quote. Not that the invoice quietly grows.
- The licence number. Plumbing work in NSW must be done by a licensed plumber, and you can check any licence through NSW Fair Trading.
- Whether after-hours rates apply. Confirm it on the phone before the van is dispatched.
Why the Cheapest Quote Is Often the Most Expensive Outcome
A very low headline price usually means one of three things, and none of them are good news.
It is a call-out price, not a job price. The number gets you a van in the driveway. The actual work is quoted once someone is standing in your yard, which is the worst possible moment to be comparing options.
The tool is wrong for the blockage. A machine punched through a grease deposit restores flow and looks like a finished job. The layer is still on the pipe wall, and you are usually back within six to twelve months. Two cheap clears in a year cost more than one proper one.
Nobody looked at why it blocked. This is the expensive one. A recurring blockage in an older line is a symptom, and clearing it repeatedly without ever putting a camera down is a subscription rather than a repair. The gap between “cleared it again” and “found the cracked joint at 8.2 metres” is the difference between paying four times and paying once.
Quote spreads in this trade are genuinely enormous, particularly on relining, where documented cases exist of two licensed plumbers quoting an order of magnitude apart for the same scope. The lesson is not that the expensive one is dishonest. It is that you cannot compare two numbers until you know both are pricing the same work.
Get a fixed price before anyone starts
R&G quotes blocked drains upfront, with a $0 call-out fee and no charge for the assessment. If we find the pipe itself has failed, we show you the footage and quote that separately rather than growing the invoice. See how we find and clear blocked drains across Sydney.
Frequently Asked Questions
Why won’t a plumber quote a firm price over the phone?
Because the four things that move the price- access, depth, roots and timing- cannot be established over the phone. A firm phone quote on a main line is either padded to cover the worst case or it will change on site. A range on the phone and a fixed price on site is the honest version.
Is a blocked drain covered by home insurance?
Clearing a blockage generally is not, because it is treated as maintenance. Damage caused by an escape of water sometimes is, depending on the policy. Check your product disclosure statement, and if there has been water damage, photograph it before anything is cleaned up.
Do I pay if the blockage turns out to be Sydney Water’s?
You are responsible for the wastewater pipes on your property up to where they connect to Sydney Water’s network. If your neighbours have the same problem, or it overflows while nobody is using water, call Sydney Water on 13 20 90 first, because that call is free and a plumber’s is not.
Is it cheaper to clear a drain repeatedly than to reline it?
Only for a while. If you are paying to clear the same line two or three times a year, the arithmetic turns over about three to four years, and you have been living with backups the whole time. The camera footage is what tells you which side of that line you are on.
