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.
the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Hang the compatible replacement leaf, fit agreed ordinary hardware and check floor clearance, alignment and closing in the unchanged opening.
Signs: the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door sags, rubs, sticks or has uneven gaps around the 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 replacement leaf may arrive unfinished, primed or factory coated. Cutting and fitting can leave edges needing the product-specified protection. Agree who supplies the finish and whether painting is included; hanging a door alone should not be mistaken for a complete decoration package.
Existing hinge recesses and screw positions need checking against the replacement leaf. Reusing a hinge depends on its condition and suitability for the new door. Damaged screw holes or a heavier leaf may change the agreed hardware work without making structural changes appropriate.
