the component no longer sits level, opens or supports ordinary use as intended. Replace the accepted ordinary decorative surround with suitable joints and fixings, leaving the agreed preparation for finishing.
Signs: the component no longer sits level, opens or supports ordinary use as intended or a practical repair or compatible installation needs a clear product and access review. Causes: ordinary wear, loose compatible fixings or minor fitting movement or local damage that does not establish a structural requirement.
Top corners and returns need appropriate ordinary cutting and fitting. Show any unusual junctions before ordering material. A compatible profile and adequate lengths matter; filling large mismatches is not equivalent to a properly planned replacement surround.
Agree filling, joint preparation and the painting boundary. A primed replacement can still need final decoration after fitting. Window glazing, specialist seals and rated-door certification are outside the task even where the new architrave sits beside those systems.
Replace the accepted ordinary decorative surround with suitable joints and fixings, leaving the agreed preparation for finishing. Limits: Ordinary decorative surrounds only. No structural jamb or opening modifications, specialist glazing, fire-door certification or hazardous-material disturbance.
