Leak in shower tray

£250

Brockwell Park, Greater London

27th Mar 2026

I previously had a leak from my shower tray, which a plumber confirmed was most likely due to failed sealant. He advised it could be fixed with resealing, so I attempted a DIY repair, but it didn’t fully resolve the issue. As a temporary measure, I applied waterproof tape, which has stopped the leak for now. However, I’ve since noticed a gap forming in the skirting board behind the shower wall, and there is also an old stain on the carpet from the earlier leak. I’m now looking for someone to properly fix the issue permanently. This would likely involve removing old sealant, resealing the shower tray correctly, and checking for any underlying issues. I’d also appreciate advice on whether anything else (e.g. movement in the tray or damage behind the wall) needs addressing.

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!
