Keep the paint label or colour reference where available. An original colour can still look different beside a weathered finish. A sample supports discussion, but no exact invisible match should be promised solely from a colour code or phone photograph.
Include nearby glass, paving, plants and fittings in the photographs. A small paint area can still need careful protection. Access to neighbouring property or removal of fixtures should never be assumed from the size of the mark.
Show whether the spot is sheltered or directly exposed and identify the material where known. The compatible exterior product must suit that setting. This task does not extend to specialist wet-area systems, waterproofing or remediation of an unresolved substrate problem.
Prepare and touch up the agreed small accessible exterior areas with compatible materials, keeping the repair boundaries clear. Scope limits: Small accessible sound exterior spots only. No full exterior restoration, waterproofing, hazardous coating disturbance or specialist high-access work.
