Blocked Kitchen Sinks

Sink draining slow or not at all? It's almost always grease — and we blast it off the pipe wall with the jetter so the drain runs freely again.

J Jason B 19 reviews · 4 days ago ★★★★★

I've had a fantastic experience from start to finish. Kevin's quote was very fair, and his work was completed to the highest standard. He turned up on time, communicated clearly, and delivered exactly what he promised me. It's rare to find someone these days who offers both great pricing and genuinely excellent service. I highly recommend Blocked Busters.

What we do

Blocked Kitchen Sinks

Kitchen sinks block up because of what goes down them — fats, oils and grease that wash in warm, then cool and set hard onto the pipe wall. It builds up layer by layer until the drain narrows to nothing, which is why a sink usually goes slow for a while before it blocks completely.

This is where our extreme high-pressure jetter comes into its own. We run specialised grease nozzles through the drain that break up the solidified grease and scour it right off the pipe wall — not just melt a narrow channel through it like a chemical cleaner does. The full width of the pipe is opened back up, so the sink drains freely and stays that way.

Blocked Kitchen Sinks on the Sunshine Coast
The process

How it works

1

Find the buildup

We work out where the grease has set hard and narrowed the drain.

2

Match the nozzle

We fit the right grease nozzle for the buildup and the pipe.

3

Jet it clean

High-pressure water breaks up the solidified grease and scours the pipe wall clean.

4

Flush & test

We flush the drain through and check it's running at full flow again.

Good to know

Common questions

Why does my kitchen sink keep blocking?

Fats, oils and grease. They go down warm and liquid, then cool and set hard onto the pipe wall, narrowing the drain a little more each time until it blocks. It's gradual, which is why the sink runs slow before it stops completely.

Do chemical drain cleaners work?

Not really — they tend to melt a thin channel through the grease that seals back up within days, and they can damage pipes. Physically blasting the grease off the pipe wall with the jetter lasts far longer.

How do you clear a grease blockage?

With our extreme high-pressure jetter and specialised grease nozzles. The nozzles break up the solidified grease and scour it off the pipe wall, opening the full width of the drain back up rather than just clearing a small hole through it.

How can I stop it happening again?

Don't pour fats or oils down the sink — let them cool and bin them — use a strainer for food scraps, and run hot water after washing up. We'll give you the specifics for your setup when we're there.

How does the ‘cleared or it’s free’ guarantee work?

If we can’t clear your blockage, you don’t pay. The guarantee applies where there’s sufficient drain access to reach the blockage. If adequate access isn’t available, we can’t guarantee it can be cleared — additional work may be needed, like installing inspection openings or extra drain access points, to reach those sections. We’ll always quote any of that before we do it.
