An ordinary hardware or alignment problem may be repairable without a new leaf. If replacement is appropriate, first confirm that the proposed external door suits the sound existing opening and exposure; a new leaf cannot remedy underlying frame or threshold defects.
A practical external door replacement decision starts with the affected item, its condition and the surrounding materials. Fit a suitable ordinary supplied leaf with agreed mechanical hardware and check closing, clearances and existing seal contact without altering the 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: normal wear in hinges, latches or compatible mechanical hardware or loose fixings, minor alignment drift or ordinary timber movement.
Handles and an ordinary mechanical lockset may be reusable if dimensions and condition are suitable. Send model details and edge photographs. Key cutting, rekeying, emergency entry and electrical access systems are separate specialist services, not implied additions to a door-leaf quote.
Existing seals need space to contact the leaf without preventing closure. Show damaged or missing strips separately in the enquiry. A leaf replacement can include checking the agreed fit against compatible existing seals, but it is not certification of a complete weather-sealing system.
