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 local area needs a bounded cosmetic repair rather than an assumed structural diagnosis. Causes: minor finish movement at a suitable stable surface or a previous patch or coating that needs preparation.
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.
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.
fill and prepare a suitable shallow surface repair. fit a local patch where backing and material condition allow. Limits: Minor ordinary stable cornice repairs and short matching sections only. No ornate heritage restoration, large loose sections, structural movement diagnosis or hazardous materials.
