Rubbing, loose hinges and latch problems should be identified before painting. Extra paint can make tight clearances worse. Suitable hardware repairs can be requested separately, but a new finish is not a substitute for correcting an underlying door movement issue.
Colour, sheen and the condition beneath the coating all influence the result. An agreed repaint should not be described as factory refinishing. Matching neighbouring aged surfaces exactly cannot be guaranteed just by choosing a paint colour with the same name.
Handles, hinges and nearby floor surfaces need an agreed protection plan. Explain whether the hardware is delicate or has a specialist function. Removal or refitting of components should be discussed, and no alteration to a certified door assembly is implied.
The agreed service covers small internal-door painting jobs, compatible surface preparation and agreed finish. Exclusions: Fire/smoke door certification or modifications, exterior coating systems, hazardous paint stripping, door replacement.
