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.
the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. 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 latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Causes: loose fixings, minor alignment drift or ordinary timber movement or local damage to an accessible component rather than an assumed structural defect.
Photograph the bottom clearance and threshold from inside and outside. An ordinary leaf fit retains the existing threshold arrangement. Changing drainage, waterproofing or the building opening is outside this task and should not be hidden inside a request to shorten the door.
A heavier replacement can demand different support from the original door. Identify the proposed material and weight where available. Fixing condition and hinge compatibility must be reviewed before hanging; ordinary replacement does not authorise reinforcement or structural modification of the opening.
