Blocked Drain Repair Sydney
When clearing isn't enough — locate the fault, get a fixed repair quote, fix it once.
If a drain keeps blocking, something is broken: a cracked pipe, a collapsed section, a root-invaded joint. We run the CCTV, mark the exact location and depth, and give you a fixed repair quote on the spot — spot excavation or no-dig pipe relining. Nothing starts until you approve the price.

Not sure this is the problem?
If you're not certain, scan it first. A photo of the drain, gully or overflow is usually enough for us to tell you what's actually going on, which service fixes it, and what that costs fixed.

Questions
- How much does drain repair cost in Sydney?
- A spot dig and repair typically runs $1,500–$5,000 depending on depth and what's on top; relining is $2,500 setup plus $450–$550 per metre. The $249 diagnostic is credited against either.
How pipe relining works
Relining repairs a cracked, root-damaged or offset pipe from the inside, without digging it up. It's the usual answer in Sydney's older suburbs where the sewer runs under a driveway, paving or an established garden.
- 1
Camera survey
The damaged section is measured and located with the CCTV camera and a sonde. This tells us pipe diameter, length, number of junctions and whether the pipe can be relined.
- 2
Clean the host pipe
The line is jetted and, where roots have grown through joints, cut back with a robotic cutter so the liner bonds to a clean wall.
- 3
Insert the liner
A felt or fibreglass liner soaked in epoxy resin is pulled or inverted into the pipe from the access point. No trench: it goes in through the existing opening.
- 4
Inflate and cure
A bladder inflates the liner against the pipe wall and it's cured with hot water, steam or UV light in a few hours. The result is a seamless new structural pipe inside the old one.
- 5
Reinstate and check
Junctions to other branches are re-opened with a robotic cutter, then a final camera pass records the finished pipe. You get the footage and a warranty certificate, typically 35 to 50 years.

| Reline | Dig & replace | |
|---|---|---|
| Time | Usually 1 day | 2–5 days plus reinstatement |
| Disruption | One access hole or none | Trench through whatever's on top |
| Typical cost | $3,000–$12,000 | $10,000–$30,000+ |
| Warranty | 35–50 years | New pipe, standard |
| Not suitable when | Pipe is fully collapsed or badly out of line | Access is impossible or too costly |
How it's priced: a setup cost of around $2,500, plus $450–$550 per metre of liner depending on pipe diameter, plus $650–$750 for each junction that has to be re-opened. We start with a $249 camera diagnostic, then give you a fixed written quote for both relining and excavation so you can compare. The $249 is credited to whichever you choose.
How Block Drains works
We're a marketplace for plumbers and drainers, not a plumbing company. We connect you with a licensed, insured drain plumber who covers your suburb, at one fixed price per job. We take the booking and handle the payment; the plumber does the work, is responsible for it, and is paid per job through us, so there's no incentive to pad the bill and nothing to negotiate at the door.
- 1
Tell us what's wrong
Pick the symptoms (toilet overflowing, sink slow, sewage outside) and your postcode. The site works out the right service and shows the fixed price before you give us a single detail.
- 2
Pick a two-hour window
Choose 'as soon as possible' or a window from 7am to 10pm, seven days. Availability is live: it's based on the plumbers who actually cover your suburb.
- 3
We assign a licensed local plumber
The job goes to the nearest available NSW-licensed drain plumber in our network. You get their name, licence number and ETA by text and email, plus a link to reschedule or cancel.
- 4
The job's done and reported
They clear the drain, put a camera through the line, flow-test everything and leave a short written report. Anything beyond the fixed price is quoted in writing first.
- 5
Your card is charged only when it's done
You save a card when you book; nothing is charged until the plumber marks the job complete. Any extra work is quoted in writing and only charged if you approve it online. Block Drains handles the payment and pays the plumber, so there's never a bill to settle at the door.

Come back for less
10% off every future job, $50 credit for every friend you refer, a discounted annual Drain Care clean, and a free return from the same plumber within 30 days if the drain re-blocks with no damage found.
