Repair and lifecycle guide

Fire door maintenance guide

Maintenance should restore the doorset’s intended function using compatible materials and competent work. Cosmetic improvement is not the same as a fire-performance repair.

Direct answer

Which defects should be dealt with first?

A door that cannot close, is wedged open, has severe damage or fails to protect a critical escape route may require urgent action. Priority should reflect people at risk, evacuation strategy, door location, credible fire spread and available interim controls—not a generic defect count.

Risk-based action

Which defects should be dealt with first?

A door that cannot close, is wedged open, has severe damage or fails to protect a critical escape route may require urgent action. Priority should reflect people at risk, evacuation strategy, door location, credible fire spread and available interim controls—not a generic defect count.

Make the immediate area safe, preserve escape, and record temporary arrangements while competent repair or replacement is arranged.

Compatible work

What makes a fire-door repair suitable?

A suitable repair identifies the original or defensible specification, uses compatible products and methods, remains within the relevant field of application and is completed by a person competent for the task. Filling damage with ordinary materials or replacing hardware by appearance alone is unreliable.

Some damage can be repaired under an approved method; other damage requires a new leaf or complete doorset. The decision should be recorded rather than hidden by paint or filler.

  • Door identity and intended performance established
  • Repair method supported by product or specialist evidence
  • Replacement components compatible
  • Work photographed and recorded
  • Door retested after repair

Ongoing management

How should a maintenance programme work?

Combine frequent user or caretaker observations with periodic competent inspection at a depth appropriate to risk. Use unique door IDs, assign actions, set risk-based dates and track repeat defects.

Where doors repeatedly fail through misuse, pressure, heavy traffic or access needs, address the underlying building and operational cause rather than repeatedly adjusting the same component.

Frequently asked questions

Fire door maintenance guide FAQs

These answers provide general guidance for England. The correct conclusion depends on the door, building, design evidence and people at risk.

Can a fire door be repaired instead of replaced?

Often, if the defect and original specification are understood and an evidence-supported repair is available. Major damage or uncertainty may make replacement more appropriate.

Who should maintain fire doors?

Use competence proportionate to the task. Routine observations can be completed in house; performance-affecting repair and uncertain defects need suitably competent specialists.

Should fire doors be painted?

Decoration can be acceptable if it does not damage seals, labels, glazing systems, gaps or hardware. Excessive paint build-up can impede operation and obscure evidence.
