Typical duration: 1 – 2 hours for fill/flush‑valve or seal replacement.
May extend if:
- leak mis‑diagnosed and pan must be lifted;
- rusted bolts need cutting out;

Is your quote fixed‑price or by the hour, and does it include the call‑out?
Will you supply WRAS‑approved replacement parts or fit items I provide?
Does the price cover all seals, valves and small sundries, or are they extra?
If the pan needs lifting, will you allow for floor/tile re‑sealing in the quote?
Do you carry public‑liability insurance and offer a workmanship guarantee?
Can you show me how to isolate the toilet in case of future leaks?
Will you provide a waste‑transfer note if any hazardous items (e.g., POPS seat) are removed?
