The remaining cornice and adjacent surfaces must be sound enough for ordinary work. Large loose or heavy sections are outside this minor service. Do not pull at a suspect section for photographs; describe the concern so suitable next steps can be discussed.
A repaired cornice section may need sealing and paint after drying. Local paint can look different from aged surrounding surfaces. List decoration separately so a cornice repair does not silently become a room repaint or promise an invisible colour match.
Where a local piece is unsuitable for repair, a matching short section may be considered. The scope should identify removal, fitting and joint finishing. It does not imply rebuilding the ceiling edge or replacing hidden framing behind the decorative material.
Repair suitable minor joints or fit an agreed short compatible cornice section, then prepare the accepted area for decoration. Scope limits: Minor ordinary stable cornice repairs and short matching sections only. No ornate heritage restoration, large loose sections, structural movement diagnosis or hazardous materials.
