Mixer Tap Leaking in Kitchen (Cartridge Replacement)

£115

Shacklewell, Greater London

3rd Feb 2026

Issue: Kitchen mixer tap leaking from the gap between the hot/cold handle. The water dribbles down the shaft when in use. No flooding, the tap is still usable for now, but needs dealing with. Thoughts:likely a cartridge replacement or issue with sealing. I'd rather not replace the whole tap, but you'll do a diagnosis first and we'll discuss. Hopefully, it's a short one-and-done job: There's a Screwfix and a Toolstation nearby. If after diagnosis, the right part is available, I can nip off and buy it. Or, I can purchase one from you if you carry spares... Budget is for labour if this is the kind of job we're looking at... I'll cover you for parking vouchers during your visit as needed.

Ali came, and knew exactly what to do. Thanks!

Fix pipe leakage under sink

£60

Brownswood Park, Greater London, N4

16th Dec 2025

I dismantled the pipes under my sink after fitting everything back together there is a leak. Specifically the leak is between the top of the ubend and the exit pipe. The problem is that the end of the ubend has a screw nut and the exit pipe is just a flat pipe so the connection isn’t tight enough

Yilmaz clearly knows what he’s doing!

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!!

Bathroom Tap Replacement & U-Bend Leak fix

£100

Haggerston, Greater London, E2

27th Aug 2025

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.

Michael arrived on time and completed the task very quickly ! Lovely guy and nice to meet you. Thank you Michael !
