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. There is also a slow dripping leak from the ubend behind the sink so I think this will need to be replaced too. I can either purchase or you can supply the ubend. Plumbers preferred.

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
