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.
List whether the request covers one face, both faces or accessible edges. A door frame and surrounding architraves are separate surfaces. Defining those boundaries helps keep a small internal-door painting quote clear before preparation begins.
Timber, coated composite and previously painted surfaces do not always take the same preparation. Send product information where available. A coating choice should follow compatibility checks rather than assuming any household paint can be applied over the existing finish.
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.
