Grooves and moulded corners can retain loose paint or dirt that affects adhesion. The profile should be visible in the enquiry photos. Preparation must stay within suitable non-hazardous methods and does not imply stripping unknown old coatings.
Carpet, hard flooring and adjacent walls need appropriate protection while low trim is prepared. Explain whether furniture can be moved away from the edges. Tight access may require more preparation than the visible length of skirting initially suggests.
Fresh trim may look different beside aged walls or an unpainted door. Discuss the intended boundary and finish expectation. The quote should identify the actual surfaces rather than imply that all adjoining paintwork will be refreshed at the same time.
The agreed service covers small interior trim preparation and recoating after substrate suitability review. Exclusions: Structural timber repair, hazardous coating removal, external window restoration, large renovation repaint.
