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 small stable joint defect may be suitable for minor repair. Repeated opening, loose material or uncertain attachment changes that assessment. Describe when the defect appeared without assuming its cause; this service does not diagnose structural movement or certify a ceiling junction.
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.
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.
