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.
internal door replacement can be appropriate when the door sags, rubs, sticks or has uneven gaps around the opening. Check the supplied leaf against the opening, hinge positions and product trimming allowance before removing the old door.
Signs: the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door closes poorly despite an otherwise sound visible opening. Causes: local damage to an accessible component rather than an assumed structural defect or normal wear in hinges, latches or compatible mechanical hardware.
Check the swing across the actual floor, including rugs and any planned flooring change. The aim is a workable clearance with an aligned leaf. Removing excessive material to compensate for an unsuitable opening is not a substitute for checking compatibility first.
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.
