Sink Blockage / Unclogging
Clearing blocked kitchen and bathroom sinks quickly, without damaging your pipes.
What Is Sink Blockage & Unclogging?
Sink blockage happens when grease, food waste, hair, soap scum or debris builds up in the drain or the trap under the sink and stops water from flowing out. HaziPlumbing clears blocked kitchen and bathroom sinks in homes and buildings across Kuala Lumpur and Selangor, finding where the blockage sits first so the sink is cleared properly and does not block again a few days later.
A blocked sink usually shows up as water draining slowly, water pooling in the basin, gurgling sounds or a bad smell coming from the drain. Our plumbers check the trap and the pipe behind it, use suitable tools for the type of blockage, and clean up after the job so your sink is ready to use straight away.

Frequently Asked Questions
Kitchen sinks usually block from grease, oil and food waste, while bathroom sinks block from hair, soap scum and toothpaste. Over time this builds up in the trap and drain pipe until water drains slowly or stops.
Common signs include water draining slowly, water pooling in the basin, gurgling sounds from the drain and a bad smell. If water backs up into the sink when another fixture is used, the blockage may be further down the line.
You can try a plunger, or place a bucket under the sink and clean out the trap by hand. Avoid harsh chemical drain cleaners, as they can damage pipes and are unsafe to mix. If the sink stays slow or the water keeps backing up, it is better to call a plumber.
Repeated blockages usually come from grease building up on the pipe walls, food waste going down the drain, or a pipe with poor slope. We check whether it is a one-off clog or a bigger drain problem so you know what to expect.
A bad smell usually comes from food waste, grease or hair trapped in the drain or trap. Clearing the blockage and cleaning the trap normally removes the smell. If it keeps coming back, the trap or the pipe may need checking.
A simple blockage in the trap or the first part of the drain is often cleared within an hour once the plumber is on site. A deeper or stubborn blockage can take longer, and we explain what to expect after checking.
We take care not to. We choose the clearing method based on the type of blockage and the condition of your pipes and sink, so the blockage is cleared without causing unnecessary damage.
Yes. We clear blockages in kitchen sinks, bathroom basins and other sinks in homes and commercial spaces across KL and Selangor.
The cost depends on where the blockage is, how severe it is and how easy the pipe is to reach. We confirm the plan and price with you before starting any work, and a photo or short description on WhatsApp helps us give a more accurate quote.
Wipe grease and oil off plates before washing, do not pour fat down the sink, and use a strainer to catch food waste and hair. Flushing the drain with hot water now and then also helps. If the sink starts draining slowly, getting it cleared early is easier than waiting for a full blockage.
