Blocked Sink across Banbury

A blocked sink disrupts your day, whether it is in the kitchen or the bathroom. Kitchen sinks block with grease, food scraps and soap. Bathroom basins block with hair, soap scum and toothpaste.

The engineer clears the trap, then rods or jets the waste pipe if needed. Hard water scale and grease need different tools, so the method depends on the cause. The engineer also checks the outside gulley, because debris often collects there.

A good visit checks the whole waste run, not just the visible trap. As a result, the sink drains freely after the work. The engineer tests the flow before leaving.

Signs you need blocked sink help

These are common signs that you need blocked sink. If you spot one, act early, because small faults often grow.

  • ✓ Water pools in the basin and drains very slowly or not at all
  • ✓ Gurgling sounds come from the plughole when water drains
  • ✓ Unpleasant smells rise from the sink drain, particularly in warm weather
  • ✓ Water backs up into the adjacent sink bowl in a double-basin kitchen setup
  • ✓ The overflow outlet starts leaking because the basin cannot empty fast enough

Our process

These steps show a typical visit. However, the exact method depends on what the engineer finds on site.

  1. 1.
    Inspect the Trap
    We check the U-bend or bottle trap beneath the sink for visible obstructions and assess whether the blockage is in the trap itself or further along the waste pipe.
  2. 2.
    Clear the Waste Pipe
    Using drain rods, a powered drain snake, or targeted micro-jetting, we remove the blockage and flush accumulated debris from the full length of the waste run.
  3. 3.
    Check the External Gulley
    We inspect the gulley or hopper where the waste pipe exits the property, clearing any debris that could restrict drainage or cause future problems.
  4. 4.
    Flow Test
    We run both taps at full pressure to verify the sink drains freely with no residual slow drainage or gurgling, confirming the blockage has been fully resolved.

Pricing guide

The price depends on the blockage and how much work it needs. Heavy grease in a kitchen sink may need jetting, which adds to the job. Send a request online and we pass it to a local engineer, who agrees the price before starting.

Blocked Sink — frequently asked questions

Why does my kitchen sink keep blocking?

Grease is the usual cause. Cooking oil sets as it cools, so it narrows the pipe bit by bit. A sink strainer helps, and so does wiping greasy pans before washing up.

Are chemical drain cleaners safe to use on a blocked sink?

Chemical cleaners may give short relief for a minor blockage. However, they can corrode old metal pipes and harm rubber seals. For a stubborn blockage, mechanical clearing is safer for your pipework.

Can a blocked sink cause other drainage problems?

Yes, it can. If the sink shares a pipe with other fixtures, a blockage in the shared section can slow them all down. This is common in older terraced homes.
