architrave replacement can be appropriate when a supplied item, trim or fitting is loose, incomplete, damaged or needs adjustment. Check decorative profile and reveal compatibility on a sound unchanged opening before agreeing removal and replacement.
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: ordinary wear, loose compatible fixings or minor fitting movement or local damage that does not establish a structural requirement.
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.
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.
