Great job quick and efficient
Leaking tap in the bathroom
£50
I would definitely recommend Christopher. Very good service. He was available on short notice & friendly. He identified the problem quickly, explained what the issue was & what my options were. In the end, he changed the leaky pipes & installed a new faucet & took time to check that everything was working properly. He managed to resolve the issue quickly, within a couple of hours eventhough he had to go & get some additional part within that time.

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.

I am looking for someone with plumbing experience to investigate the source of the leak and carry out any necessary repairs.
