Inspection Defect Guide
Fire Door Inspection Defects
Fire door inspections identify defects that may affect compartmentation, smoke control, safe escape and the overall fire-resisting performance of a door set.
How Defects Are Recorded
Common Issues Found During Fire Door Assessments
Inspectors review door sets against accepted inspection criteria and document visible defects where observed.
During a fire door inspection, defects are recorded with photo records where captured, location notes, condition comments and remedial priority guidance where required. This helps duty holders understand what was observed, where issues were found and which actions may need attention first — including follow-up remedial works or re-inspection where appropriate.
For follow-up planning, see what happens after a fire door inspection, inspection vs maintenance and certification, and our Regulatory Reform Fire Safety Order guidance.
