The inspection is more than checking whether a door shuts. It considers the door leaf, frame, clearances, seals, hinges, self-closing device and relevant ironmongery, together with visible damage, alterations and anything else that may affect the door's performance.
The door and frame
The inspector considers the condition of the door leaf and frame, signs of damage or distortion, and whether the door appears to fit its frame appropriately. The inspection is visual unless a different scope has been agreed, so concealed construction cannot automatically be confirmed.
Gaps, seals and interfaces
Clearances around the door are important because excessive or inconsistent gaps can affect smoke and fire resistance. Intumescent and smoke seals, where required, should be present, suitably located and in serviceable condition. The threshold and any drop seal or other smoke-control feature should also be considered where relevant.
Self-closing performance and ironmongery
A fire door that is intended to self-close needs to close fully into its frame from the appropriate opening positions. Hinges, closers, latches and other relevant ironmongery should be secure and suitable for the door. Defective or poorly adjusted hardware is a common reason for otherwise serviceable doors failing to perform properly.
Glazing, letterplates and alterations
Vision panels, glazing systems, letterplates and other apertures can be significant parts of the door set. Unauthorised alterations, new locks, damaged glazing beads, replacement letterplates or other changes should be considered because they may affect the intended fire performance.
What the report should include
A useful inspection report identifies the individual door, records the visible findings and distinguishes repairable defects from issues requiring further investigation or replacement. A door-by-door defect schedule makes it easier for a managing agent to instruct works and then verify that the remedial work has been completed.
