Scope of Works
• inspect mixer, trim and visible pipework to diagnose leak, low flow, temperature or stiffness issues
• isolate water supply and remove handles/trim to access cartridge or ceramic discs
• replace cartridge, seals or washers and descale components where required
• reassemble, pressure test and adjust hot/cold balance and flow
• fit a replacement mixer or order specialist parts if the valve is beyond repair and advise on options
• remove and dispose of old parts, tidy the work area and use PPE where there is scale or contamination risk

Time on Site
Most straightforward mixer cartridge replacements take 0.5–1 hour on site; diagnosing intermittent temperature or concealed valve faults can take 1–4 hours or require a follow‑up visit for parts. Factors that extend time include seized fittings, hidden valves behind tiles, waiting for ordered parts and restricted access in small bathrooms
Questions to Ask Your Tradie
• are you insured and do you carry public liability cover?
• can you supply the cartridge or will I need to buy parts separately and what is the parts warranty?
• will you isolate and drain the supply and do you expect any water outage upstairs or elsewhere?
• what guarantee do you offer on labour and fitted parts and for how long?
• will work require opening tiles or an access panel and how will you reinstate finishes?
• do you charge for call‑out separately from repair time and what payment methods do you accept?
How to Avoid Surprises
• ensure isolating valves are accessible and know where the stopcock is
• clear the area around the bath, remove toiletries and protect nearby surfaces
• provide short‑term parking or let the trader know of restrictions in flats or gated estates
• mention hard‑water scale or previous repairs and whether the mixer is still under any manufacturer warranty
• expect a short hot water outage and agree where the engineer can store removed tiles or old parts
• advise of pets, insurance requirements or building management rules before the visit
