Repair or replace? Deciding what to do with a failed fire door

When a fire door fails an inspection, the next question is practical: do we repair it or replace it? Get that decision right and you protect both safety and budget. Get it wrong and you either spend money replacing a door that could have been fixed, or you patch up a door that should have been condemned.

This article sets out how to think about the choice, how to keep a repair compliant, and what to do while the work is pending.

The deciding question

There is one question underneath the decision: can the door be returned to its certified condition? A fire door is only as good as the assembly it was tested as. A repair is appropriate when it restores the door to that certified specification using compatible, certified components and approved methods. If it cannot be restored to spec, it needs replacing.

What can usually be repaired

Many common failures are genuinely repairable without touching the leaf itself:

• Replacing worn, damaged, missing or painted-over seals with the correct certified product
• Adjusting or replacing a self-closing device so the door closes and latches properly
• Replacing missing or incorrect hinge screws, or fitting the correct fire-rated hinges
• Replacing damaged but repairable glazing beads or fire-rated glazing
• Re-hanging or adjusting a dropped leaf so the gaps return to tolerance

The key constraint is that repairs must follow the door manufacturer's instructions and use components covered by the certification. A repair carried out with the wrong parts, or that cuts or fills the leaf in ways the certification does not allow, can quietly invalidate the rating even though the door looks fixed.

When replacement is the answer

Some situations point clearly to replacement rather than repair:

• Significant damage to the leaf itself, such as deep gouges, holes, splitting or warping that cannot be made good within the certification
• A door that has been modified beyond what its certification permits, for example a standard letterplate cut into it
• A door of unknown or uncertain origin, with no certification evidence, where you cannot establish what it is supposed to be
• A door that fails repeatedly on the same point, where repeated repair is really just deferring the inevitable

In these cases the honest answer is that you cannot demonstrate the door will perform, and a certified replacement is the route to confidence.

Do not forget the interim

A door that has failed on something critical, that will not close or latch for instance, is not protecting anyone in the meantime. Where a defect is serious, interim measures may be needed while repair or replacement is arranged, and the building's fire risk assessment and a competent adviser should guide what those are. The point is that "it is on the list" is not the same as "it is safe", and the gap between identifying a serious defect and fixing it needs managing.

Record the decision and the evidence

Whichever route you take, record it: what the defect was, what was decided, what was done, by whom, and with before-and-after evidence. That record is what links back into the door's history and supports the golden thread of the building's safety information. The relevant standard for the assessment is BS 8214, and seals specifically are covered in our guide on intumescent and smoke seals.

How DoorTRACE helps

In DoorTRACE every defect carries its priority, its remedial action and its evidence, so the repair-or-replace decision and the work that followed are recorded against the door for good. Repeated failures on the same door become obvious across its history, which is often the signal to replace rather than repair again. See defect management or book a demo.
