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!
