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: a practical repair or compatible installation needs a clear product and access review or the component no longer sits level, opens or supports ordinary use as intended. Causes: an incomplete assembly or a mismatched replacement component or ordinary wear, loose compatible fixings or minor fitting movement.
Measure both sides and the top and identify whether one face or both are included. A doorway may have different trim on each side. The quote should describe the actual surround instead of assuming one opening means every adjacent decorative surface.
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.
