Shower Mixer Valve Repair in Kingston upon Thames

Local engineers, same-day emergency response, fixed prices — from the team based right here in KT1/KT2.
Shower Mixer Valve Repair for Kingston upon Thames homes
Thermostatic cartridges scale up and stick, which is why a shower suddenly runs cold or refuses to reach temperature. We identify the valve brand, source the correct cartridge and service the valve body, filters and check valves at the same time — the filters are blocked far more often than people expect.
Where a valve is obsolete or the body is corroded we replace it, matching the existing plate and pipe centres wherever possible so there's no tiling work. We cover Kingston upon Thames, New Kingston upon Thames, Putney, Richmond, Surbiton and the wider South West London area.
When your boiler dies on a Sunday morning or a pipe bursts under the kitchen sink, the last thing you want is a national callout line dispatching whoever's "nearest" — sometimes an hour away. Maxfix Plumbing and Heating is based in Kingston upon Thames.
Areas of Kingston upon Thames we cover: Kingston town centre, Norbiton, Coombe, Canbury, Kingston Hill.

Frequently asked
Your questions, answered
Why does my shower go cold when a tap is used?
Either a failed thermostatic cartridge or low, unbalanced pressure. We test both — sometimes the real fix is a shower pump or pressure correction rather than a new valve.
Can a shower valve be repaired or must it be replaced?
Most branded valves can be repaired with a new cartridge and clean. Replacement is only needed when the body is corroded or parts are discontinued.
Will you have to remove tiles?
Usually not. Concealed valves are serviced through the face plate, and replacements are matched to the existing pipe centres wherever possible.
The shower drips after turning off — is that the valve?
Yes, typically a worn cartridge seal or a failed check valve. Both are replaced during a standard repair visit.
