A practical architrave replacement decision starts with the affected item, its condition and the surrounding materials. 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: an incomplete assembly or a mismatched replacement component 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.
Existing paint, adhesive and fasteners affect how the old surround can be removed. Some surrounding making-good may be needed. The service should not promise damage-free removal from every finish, and any unexpected deterioration needs discussion before the opening is covered again.
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.
