Joint finishing needs to suit the profile without flattening its shape. Existing paint build-up or textured surfaces can affect the match. Agree the intended finish before work starts, including whether remaining surrounding defects are outside the quoted minor repair.
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.
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.
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.
