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 practical internal door replacement decision starts with the affected item, its condition and the surrounding materials. Hang the compatible replacement leaf, fit agreed ordinary hardware and check floor clearance, alignment and closing in the unchanged opening.
Signs: the door closes poorly despite an otherwise sound visible opening or the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Causes: normal wear in hinges, latches or compatible mechanical hardware or loose fixings, minor alignment drift or ordinary timber movement.
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.
Factory cut-outs can restrict which handle or latch will fit. Show the hardware from both sides and the latch edge. Ordinary compatible hardware transfer can be considered, but existing holes should not be assumed to match a different product simply because both are internal doors.
