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.
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.
An external opening cannot always remain exposed while fitting or finishing proceeds. Scheduling depends on safe conditions and product requirements. Discuss forecast-sensitive stages and the finish plan before the visit rather than assuming the opening can be left incomplete overnight.
Identify an authorised person who can remain available and explain any other access route. Keep pets and belongings away from the opening. Agree the handling and storage of the old leaf so a temporary opening does not create an unmanaged access problem.
Fit a suitable ordinary supplied leaf with agreed mechanical hardware and check closing, clearances and existing seal contact without altering the opening. Scope limits: Ordinary non-rated solid leaf replacement only. No structural opening work, glazing systems, fire-door certification, building-envelope alterations or specialist security work.
