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 supplied item, trim or fitting is loose, incomplete, damaged or needs adjustment. Causes: local damage that does not establish a structural requirement or an incomplete assembly or a mismatched replacement component.
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.
Complete separately agreed paint after preparation dries. Decorative trim replacement does not correct structural frame movement. Limits: Ordinary decorative surrounds only. No structural jamb or opening modifications, specialist glazing, fire-door certification or hazardous-material disturbance.
