Emergency Blocked Sink Services

Fast sink unblocking for kitchens, bathrooms and utility rooms.

Kitchen Sink Unblocking

Kitchen sink blocked by food waste, grease and fat build-up. We clear kitchen sink blockages using drain rods, augers and water jetting where needed.

Bathroom Basin Unblocking

Bathroom basin blocked by hair, soap scum and toothpaste build-up. We clear basin traps and waste pipes to restore free flow.

Trap and U-Bend Clearance

Blockage in the sink trap or U-bend is the most common cause of a blocked sink. We remove and clean traps that are clogged with debris.

Waste Pipe Unblocking

Blockage further down the waste pipe beyond the trap. We use drain rods and augers to reach and clear blockages in sink waste pipes.

Grease and Fat Blockage

Cooking fat and grease poured down the sink solidifies in the pipes and causes blockages. We clear grease blockages and advise on prevention.

Gully and External Drain Blockage

Blocked sink may be caused by an external gully or drain blockage rather than the sink itself. We check and clear external blockages.

Blocked Sink FAQs

Common questions about blocked sink emergencies

Can I pour boiling water down a blocked sink?

Boiling water can help with grease blockages but should not be poured down a PVC waste pipe as it can soften and damage the pipe. Warm water with washing up liquid is safer for grease.

Should I use a chemical drain unblocker?

We do not recommend chemical drain unblockers. They can damage pipework, rubber seals and chrome finishes. They are hazardous to handle and harmful to the environment.

What causes most kitchen sink blockages?

The most common cause is cooking fat, oil and grease poured down the sink. This solidifies in the pipes and traps food waste. Also coffee grounds, rice, pasta and vegetable peelings.

What causes bathroom sink blockages?

Bathroom sinks are usually blocked by a build-up of hair and soap scum in the trap and waste pipe. This forms a sticky mass that catches more debris over time.

How do you clear a blocked sink?

We start with the trap or U-bend underneath the sink. If the blockage is there we remove and clean it. If the blockage is further down we use drain rods or an auger to clear it.

How can I prevent sink blockages?

Never pour cooking fat, oil or grease down the sink. Use a sink strainer to catch food waste. For bathroom sinks use a hair catcher over the plug hole. Run hot water through the sink weekly.
