Identify the whole door, frame or trim section to be coated, including any edges and returns you want finished. A complete timber component can need more preparation than an isolated paint spot. The quote should identify exactly where the new finish starts and stops.
Old paint condition and product history affect preparation. Show flaking, glossy and bare sections together. Hazardous coatings and extensive specialist stripping are excluded; a compatible system should be selected only after the accepted sound substrate is understood.
A painted door or window component still needs suitable movement and contact clearances. Excess paint build-up can affect operation. Agree which accessible faces can be coated and how they will remain separated while drying, without treating painting as a substitute for alignment repair.
Prepare and paint the accepted accessible timber component with a compatible exterior system, protecting adjacent surfaces and operating clearances. Scope limits: Complete ordinary accessible sound timber components only. No glazing work, structural rot reconstruction, hazardous stripping, waterproofing or high-access specialist work.
