Fix Leaky Mixer Tap and Handle Issue

£50

Wallington Square, Greater London

7th Nov 2025

Looking for a handyman or plumber to repair my kitchen mixer tap. The tap is leaking, and the handle is stuck (internal metal part and screw involved). Task may involve removing the handle and making a basic repair or adjustment. Budget: £50 for labour, plus up to £20 for parts if needed. Requirements: • Experience with kitchen taps and plumbing • Bring your own tools The leaks below the handle I’m pretty sure and I think the handle has to be replaced plus inner part due to there being no screw behind the screw handle to remove it.

Fix a leaking bottle trap

£80

Acton Green, Greater London, W4

24th Oct 2025

Need a leaking bottle trap under sink fixed. Reattach or replace. Very short on space

Really happy I found Silva. He’s clearly very talented and skilled. What was thought to be a simple task of replacing a bottle trap, turned into a complicated job because of the structure and placement of my pipe work. Silva went the extra mile to disconnect and re attach the pipe and guided me on what he thought was best & not the easiest for him. Really pleased I’ve found him!! I’ve already booked him in for more work. Highly recommend!!

The ceramic discs in my old basin taps are broken and won’t stop dripping. Want to replace with new pair purchased online.

I need someone to fix my downstair neighbour's bathroom ceiling. There is some minor damage caused due to a single incident of a tap in my bathroom that was left open for a short period of time. It's a small hole in their celing, photos attached. We can confirm that this is not an issue that also requires input from a plumber. Please send your quotes

Brilliant! Thank you so much Jason
