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!!
