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.
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.
A touch-up can differ in sheen, texture or colour from aged paint. Agree whether a visible local finish is acceptable before proceeding. Repainting a complete component may be a better separate option, but it must not be silently added to the spot-work quote.
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.
