Blocked sink help in London
A slow sink is not always blocked at the plughole. Tell us whether one basin is affected or whether water backs up elsewhere too.
What we do
Tell us about the job so we can check the scope and the next step.
- Slow kitchen or bathroom sinks
- Waste and trap blockages assessed
- Multiple affected outlets checked for wider drainage problems
- Further drainage work scoped separately when needed
Blocked sinks in London
Water draining slowly from one basin may point to a local waste or trap problem. If a second sink, shower or outside gully also backs up, the obstruction may be further along the shared drain. Those situations need different access and equipment.
Stop running water into an overflowing sink. Tell us which outlets are slow, whether there is a smell or leak at the trap, and what you have already tried. Do not mix drain-cleaning chemicals or take apart pipework if you are unsure how to isolate it.
One slow sink or several affected outlets?
If only the kitchen sink empties slowly, the waste and trap beneath it may be where the problem begins. If another sink, shower or outside gully is also slow, the shared drain needs consideration instead of treating the plughole as the whole fault.
Tell us whether water backs up when a washing machine or dishwasher drains into the same waste. This detail helps identify when several fixtures share the same route. Do not assume that a chemical poured into one basin will clear a problem further along.
What to do while the sink is blocked
Stop using an overflowing basin and move items away from water beneath the cabinet. If you have already used a drain chemical, tell us exactly what it was; do not add another product or mix chemicals, because the result can be hazardous.
Note any gurgling, smell or leak at the pipe connections. Photographs under the sink are useful only if you can take them safely without opening pipework or reaching near electrical appliances. Tell us if other people share the drain.
Checking the waste and drainage scope
A local sink obstruction may be accessible at the waste or trap. A blockage farther along a shared pipe or external drain can require separate drainage equipment. We ask about the affected outlets and access before deciding which type of visit to arrange.
Recurring blockages may need investigation rather than repeated attempts at clearing. Our main drainage page explains the existing manual unblocking and CCTV routes. We do not claim that every blocked sink can be cleared by the same method or in one visit.
Request help and confirm costs
Give us your postcode, the room affected, whether the water drains at all, and what has already been tried. Mention chemicals, leaks under the basin and any other blocked outlet so the scope is assessed correctly.
We confirm the appropriate visit and applicable charge before booking. If a local waste problem turns out to involve the wider drain, we explain the findings and quote any additional work rather than treating it as an automatic extension of the first job.
Frequently asked questions
Can you help with a blocked kitchen sink?
Yes. Tell us whether only that sink is affected and whether any water is leaking beneath it. We check the right approach before confirming a visit.
Why does my kitchen sink drain slowly?
The waste or trap may be restricted, or the problem may lie farther along the shared drain. Tell us whether any other outlet is slow too.
Should I keep using chemical drain cleaner?
Do not mix products or add more after an unsuccessful attempt. Tell us which product was used before a visit so the work can be assessed safely.
What if the sink and shower are both blocked?
That can point to a shared waste or wider drainage fault. Tell us both outlets are affected so we can check the right scope and equipment.
Can you check a blockage that keeps returning?
Yes, describe how often it returns. Repeated problems can need a drainage investigation rather than another local clearance attempt.
