A sound leaf that only rubs or latches poorly may suit adjustment or hardware repair instead. Replacement is considered for an unsuitable or damaged leaf after checking that the existing opening can accept the proposed door.
A hollow-core or factory-finished leaf may allow only limited edge trimming. Share the exact product specification before purchase. A door that needs more material removed than its instructions permit should be exchanged for a suitable product rather than improvised to fit.
Clear the swing and provide somewhere safe for the removed door. Agree whether disposal is required before the visit. If the existing frame is damaged or movement is apparent, the replacement plan needs review rather than using a new leaf to conceal the problem.
Show which side carries the hinges and how the door swings into the room. Nearby furniture, another door or a light switch can affect practical use. Replacing the leaf does not automatically include reversing the opening direction or moving the stop.
Hang the compatible replacement leaf, fit agreed ordinary hardware and check floor clearance, alignment and closing in the unchanged opening. Scope limits: Ordinary compatible internal leaf replacement only. No structural opening changes, fire or smoke-rated doors, certification, locksmith services or powered security integration.
