SINK UNBLOCKING · LONDON
Blocked sink help in Lewisham
A sink that drains slowly, holds standing water or smells unpleasant can interrupt a kitchen or bathroom. Blockage Busters helps clear blocked sinks at homes, rented properties and business premises in Lewisham. Tell us which sink is affected and whether any other fixtures are backing up so we can discuss the appropriate next step.

Common signs of a blocked sink
- Water drains more slowly than usual or remains in the bowl.
- Gurgling comes from the waste pipe when water runs.
- Unpleasant smells persist around the plughole.
- Water backs up into another sink or appliance connection.
Kitchen waste pipes may collect grease and food debris. Bathroom basins can become restricted by hair, soap residue and other deposits. A problem affecting several fixtures may be further along the drainage system rather than in the sink trap alone.
What to do while waiting for help
Stop running water into a sink that is backing up, and avoid using appliances that discharge into the same waste pipe. Remove loose debris from the plughole only if it is easy to reach. Avoid mixing chemical products. If you have already used a drain cleaner, tell the engineer what it was before work begins.
How we assess and clear the blockage
We assess the symptoms, pipe layout and available access before agreeing the work. The clearance method depends on where the obstruction is and the condition of the pipework. We explain the proposed approach and quote before proceeding. If the symptoms suggest a wider drainage problem, we discuss whether additional investigation is appropriate.
If the blockage keeps returning
Repeated blockages can need more than another clearance. An appropriate CCTV drain survey can help investigate accessible drainage and visible defects further along the system. A camera survey is not automatically required for every blocked sink; the recommendation depends on the findings and access.
Arrange access to your Lewisham property
Provide the full postcode, building number or name, and a contact number. Mention parking restrictions, entry arrangements and who can authorise the work. For rented properties, tell us who will meet the engineer. For business premises, share opening hours and any restrictions affecting access.

Accessible fittings and concealed waste routes
When booking sink help in Lewisham, mention whether the waste pipe is accessible beneath the sink or disappears behind fixed units. Clear loose belongings where safe, leaving pipe joints in place. Point out existing leaks before work starts.
Describe whether water remains after sink use or enters during another appliance’s discharge. Mention symptoms elsewhere and any recent changes to the connections. This helps direct checks without assuming the restriction is at the plughole.
What if both bowls back up?
Tell us whether they are affected together and what was being used beforehand. The connected waste route may need assessment, but the symptoms alone do not locate the obstruction.
Does another clearance always solve recurrence?
Not necessarily. Explain what earlier work involved and whether normal drainage resumed. A remaining restriction or issue further along the route may warrant different checks.
Should I run an appliance to demonstrate it?
Do not deliberately reproduce a backup where overflow is possible. Describe the behaviour already observed and stop using appliances that make it worse.
