Leak coming from the sink, and the water on top of the cupboard

£100

Roehampton, Greater London

25th Aug 2026

noticed a problem in the kitchen. There is a leak coming from the sink, and the water is getting onto the top of the cupboard underneath. I think it may be something as simple as one of the rubber seals having become dry and worn over the years, rather than anything caused by normal use. However, it would be best for a plumber to have a look at it and replace whatever is needed.

Repair loose kitchen tap mounting + leaking toilet flush pipe

£100

Hampstead, Greater London, NW3

24th Aug 2026

Two small plumbing/repair jobs: 1. Kitchen tap mounting: an auxiliary kitchen tap has come loose because the laminate worktop has cracked/broken around its mounting hole beside the sink. The tap and pipework appear intact and are currently supported. I would like a neat, permanent repair rather than simply filling the damaged area — likely involving a suitable reinforcing/cover plate and remounting the existing tap. The space is quite tight beside the sink, so some cutting/drilling or fabrication of a metal plate may be required. 2. High-level toilet cistern: an older Burlington-style high-level cistern has a very small clean-water leak around the flush-pipe connection when the toilet is flushed. Only a few drops at present. I would like the joint/seal inspected and properly repaired. Photos available. Ideally looking for someone experienced with plumbing and practical kitchen/worktop repairs who can supply or advise on the necessary small parts/materials.

Replace Leaking Kitchen Sink Waste Trap / P-Trap

£75

Bermondsey, Greater London, SE1

17th Aug 2026

I’m looking for a plumber to repair my kitchen sink waste pipe. The existing P-trap/U-bend has come apart and I haven’t been able to refit it correctly. I purchased what I thought was the correct replacement, but it appears the fittings/washers aren’t compatible with my existing pipework. Job required: * Assess the current waste pipe setup. * Supply any correct fittings/washers if needed. * Replace and fit a new P-trap/U-bend. * Ensure all joints are watertight and test for leaks before leaving. The sink is currently unusable as the waste pipe has come apart (see photos). Please let me know: * Your availability. * Whether you’ll bring any standard 40mm waste fittings that may be required. * Your total price including any small parts. Looking to have this fixed as soon as possible.

Great job and called out straight away to us - would highly recommend

Leak in the kitchen

£100

Chingford Green, Greater London

Kitchen Leak Investigation and Repair Required I have a kitchen leak that is appearing between the laminate floorboards. The leak often occurs after the dishwasher has been running, particularly towards the end of the cycle when it is draining. I am looking for someone with plumbing experience to investigate the source of the leak and carry out any necessary repairs.

Yilnas did an excellent job. He quickly identified the source of the leak and repaired it efficiently. He was professional, polite, courteous, and clearly knew what he was doing. I would happily recommend him and would not hesitate to use his services again.
