A practical cornice repair decision starts with the affected item, its condition and the surrounding materials. Repair suitable minor joints or fit an agreed short compatible cornice section, then prepare the accepted area for decoration.
Signs: a stable local hole, dent, crack, patch edge or surface mark is visible or a finish looks damaged and needs preparation before painting. Causes: a previous patch or coating that needs preparation or minor finish movement at a suitable stable surface.
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.
Cornice profiles differ in projection and shape, even where the front view looks similar. Send end or side details where already visible. The service covers ordinary profiles and minor work, not replication of ornate heritage mouldings or specialist decorative restoration.
Allow finishing materials to dry and agree the paint boundary. Report recurring separation rather than repeatedly covering a moving joint. Limits: Minor ordinary stable cornice repairs and short matching sections only. No ornate heritage restoration, large loose sections, structural movement diagnosis or hazardous materials.
