Begin with a fault diary, even if it is brief
A useful report says when the problem started, how often it appears and what changes it. Note whether a door binds after rain, a fitting loosens only when fully loaded, a stain darkens after using a nearby appliance, or a drawer fails at one point in its travel. Include previous repairs and any parts already replaced. This evidence prevents the visit starting with a blank surface after the customer has cleaned, tightened or covered the symptom. Camden Council’s appraisal recognises distinct commercial and residential sub-areas, but the same diagnostic habit helps in both: understand normal use and the sequence of failure before choosing a tool or material.
