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.
Exposed edges and ordinary joints need an agreed preparation boundary. Painting cannot reconstruct rotten timber or correct structural movement. If deterioration appears during preparation, discuss suitable separate work before applying a finish that could conceal the condition.
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.
