As building owners, we all want to keep maintenance costs down. When a fire door fails an inspection or starts sticking, the immediate hope is that it can be quickly repaired.
While many issues—like worn hinges or failing closers—can be fixed by a specialist, there comes a point where a fire door is simply beyond repair. Attempting to “patch up” a severely compromised door is illegal and incredibly dangerous.
Here are the clear signs that it is time to bite the bullet and invest in new fire doors for your property.
1. Structural Damage to the Door Core
Fire doors are built with a specialized solid core (often timber, particleboard, or mineral core) designed to burn at a slow, predictable rate.
- Deep Gouges or Holes: If a door has been severely damaged by impacts, vandalism, or heavy equipment, exposing the inner core, it cannot be safely repaired.
- Modifications: If a previous tenant or contractor has cut large holes in the door (for instance, to install uncertified ventilation grilles or letterboxes), the fire rating is permanently voided.
2. Severe Delamination or Splintering
The outer layer (veneer or laminate) of a fire door isn’t just for aesthetics; it protects the core.
- If the edges of the door are heavily splintered, or the surface veneer is peeling away (delaminating) significantly, the door’s structural integrity is compromised. This often happens at the bottom of doors in high-traffic areas where they are repeatedly kicked or hit by trolleys.
3. Excessive Warping or Bowing
A fire door must sit flush against its frame to create a tight seal when the intumescent strips expand.
- Over time, changes in humidity or poor initial installation can cause a heavy timber door to warp or bow.
- If the door is significantly bowed, it will never sit flush in the frame again. No amount of hinge adjustment can fix a warped door—it must be replaced.
4. Uncertified Glass Replacements
Many fire doors feature vision panels (glass windows). This glass is highly specialized, fire-rated ‘integrity’ glass.
- If a panel was broken and replaced by a standard glazier using normal glass or non-fire-rated glazing tape, the door is a severe hazard. In a fire, normal glass shatters in seconds.
- While the glass can sometimes be professionally replaced, if the wooden glazing beads holding the glass have been badly damaged or modified, replacing the entire door is often the safest and most cost-effective route.
5. Age and Missing Certification
Every fire door must have proof of its fire rating, usually in the form of a certification plug on the top edge or a label on the side.
- If you have inherited an old building with heavy wooden doors, but there is absolutely no certification, no traceability, and they do not meet modern BM TRADA or BWF-CERTIFIRE standards, they should be upgraded. You cannot legally prove they will hold back a fire.
