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 loose fixings, minor alignment drift or ordinary timber movement.
A nominal door size is only a starting point. Measure the existing leaf and show the clear opening at several points. Differences can affect the available margins, so ordering a replacement before checking the frame may leave too little material for a suitable fit.
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.
