Blocked Basin Clearance
Blocked basin clearance restores proper drainage when a bathroom sink is slow to empty, overflowing, or giving off unpleasant smells. The service focuses on finding the cause of the blockage and clearing it safely, then checking the basin is draining freely again.
More information
What blocked basin clearance covers
Blocked basins are usually caused by a build-up close to the plughole or in the trap. The service is designed to fix the immediate problem and confirm everything is running as it should.
- Identify where the blockage is forming (plughole, trap, or waste pipe)
- Clear common causes like hair, soap residue and limescale build-up
- Restore normal flow and check drainage performance
- Reduce odours by removing trapped debris and stagnant water build-up
- Inspect the trap and waste connections and refit securely after access
- Provide practical guidance to help prevent repeat blockages
When you should book this service
This service is a good fit if your basin:
- Drains slowly, gurgles, or backs up
- Overflows when running the tap
- Smells even after cleaning the bowl and plughole
- Blocks repeatedly after short periods of normal use
- Is in a rental property between tenancies or after heavy use
What happens during the visit
The work starts with simple checks to confirm symptoms and locate the restriction. Access is then gained at the most appropriate point, often at the plughole or under-sink trap, to remove the build-up without damaging fittings.
Once cleared, the basin is tested with running water to confirm free-flowing drainage. Any disturbed seals or connections are checked and left watertight.
After the blockage is cleared
You will get a clear explanation of what caused the blockage and what was done to resolve it. If there are signs of an underlying issue, such as a partially restricted waste run or recurring limescale, you will be advised on the next sensible step.
Where helpful, you will also be given straightforward prevention tips, such as better hair capture, safe cleaning routines, and early warning signs to watch for.
