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.
The edge of the damaged paint may need suitable ordinary preparation before a touch-up. Show surrounding flaking and previous repairs. Hazardous-material disturbance and extensive stripping are excluded; the accepted area must be sound enough for the proposed local treatment.
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.
