What a fair quote should include
- Call-out
- Clearing the trap and waste with a machine (not just a plunger)
- Flow test of the sink and any dishwasher or washing machine on the same line
What pushes the price up
- Grease that has set hard along the waste line needs jetting, not a snake
- A blockage further down the shared line turns a sink job into a drain job
- Old galvanised waste pipes can crack when disturbed

Questions
- How much does a blocked sink cost in Sydney?
- Typically $150–$300 in business hours, with most quotes around $220 (October 2026). Block Drains charges $199 fixed, including call-out, at any hour.
- How much more is it after hours?
- Most Sydney plumbers add 20–50% for nights and weekends and 50–100% on public holidays, plus a call-out of $0–$200. Our price doesn't change.
- Can I unblock a sink myself?
- Often, yes. Clear the trap under the sink with a bucket underneath, and use a plunger with the overflow covered. Skip caustic drain cleaners: they rarely shift grease and damage older pipes.
- Why does my sink keep blocking?
- Usually grease building up in the waste line. A one-off clear treats the symptom; jetting the line removes the build-up.
