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 door sags, rubs, sticks or has uneven gaps around the opening 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.
Show how the doorway is exposed to weather and provide the product’s installation conditions. Exposure can affect whether the selected leaf is suitable. Replacing a leaf cannot correct a defective wall envelope, and no weatherproofing performance should be inferred from a photo quote.
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.
