Drainage & Blockages

Blocked Sink Clearance

Blocked sink clearance restores normal drainage when your kitchen or utility sink is slow, backing up, or giving off unpleasant odours. The aim is to locate the restriction, clear it using the right method for your pipework, and confirm wastewater is flowing freely again.

More information

What blocked sink clearance includes

Blocked sinks are often caused by a build-up of grease, food waste, soap residue, or debris. This service focuses on removing the blockage safely and getting your sink back to normal.

  • Checks to confirm the blockage and assess how severe it is
  • Locating the likely position and cause of the restriction
  • Clearing the blockage using suitable tools and methods
  • Testing the sink and waste to confirm free-flowing drainage
  • Practical advice to reduce the risk of repeat blockages

When this service is right for you

This service is a good fit if the sink is draining slowly, gurgling, or backing up when you run the tap. It is also appropriate if there is an unpleasant smell from the plughole, or if water overflows when using a dishwasher or washing machine connected to the same waste.

How the clearance is carried out

The work starts with a quick assessment of the symptoms and recent usage, then a check of the waste and trap area. The blockage is cleared using the least disruptive approach first, stepping up only if needed. Once cleared, the sink is tested to ensure the flow has returned to normal and the problem is resolved.

Aftercare and preventing repeat blockages

After clearance, you will be told what most likely caused the issue and what to change day to day. Simple steps, such as managing fats and food scraps and using strainers, can significantly reduce repeat call-outs. If there are signs of a deeper issue, you will be advised on the next sensible step.

Frequently Asked Questions

What usually causes a kitchen sink to block?
Most blockages come from a build-up of grease, food scraps and soap residue inside the waste pipe. Over time, this narrows the pipe until water can no longer pass freely.
Do I need to stop using the sink before you arrive?
If the water is backing up or close to overflowing, avoid running taps and appliances connected to the same waste. If it is only slow draining, minimise use to prevent it worsening.
Will you need to remove pipework to clear the blockage?
Often, no. Many blockages can be cleared through access at the sink waste without dismantling much. If removal is required, it is usually limited to the trap or an accessible section to reach the restriction safely.
Is blocked sink clearance safe for older pipework?
Yes, when the method is matched to the pipework and the cause of the blockage. The approach should avoid unnecessary force and focus on restoring flow without damaging joints or seals.
How can I prevent my sink from blocking again?
Let cooking fats cool and dispose of them in the bin, not down the sink. Use a plughole strainer for food waste and avoid washing coffee grounds and starchy foods into the waste. Regular hot water flushing can help, but it will not solve an existing blockage.
