Fire door maintenance

Fire door maintenance: can your door be repaired?

A survey finding does not automatically mean a complete replacement. The useful question is whether a suitable repair can address the defect while retaining the performance required for that door. That decision needs the condition of the complete doorset, the building requirements and the available evidence - not just a photograph of the damaged part.

Start with the door, frame and building requirement

A gap, damaged seal or closer problem may be the visible symptom rather than the whole defect. Before pricing a permanent solution, review the leaf, frame, glazing, hardware, surrounding construction and operation together. Check any labels, plugs, product records and earlier alterations. The rating and smoke-control requirements should come from the relevant building information; a heavy leaf or an FD30 description in a schedule is not enough on its own.

Identify the door and its exact location
Review the survey, fire strategy and product records
Check the complete assembly and existing alterations

When targeted maintenance may be appropriate

Possible maintenance tasks include closer adjustment, renewal of compatible seals or hinges, and permitted repairs to fixings or local damage. Each task must suit the particular assembly and available repair evidence. A replacement seal needs the correct type and dimensions, not merely the same colour. A door that slams may need investigation of the closer, alignment and latch rather than immediate replacement of every component.

Confirm compatible replacement components
Check the permitted repair method before work
Recheck closing and latching after maintenance

Excessive gaps need a diagnosis

A photograph can show an uneven gap without explaining why it exists. Frame movement, distortion, hinge wear, previous trimming and installation defects can require different responses. Packing, trimming or adding lipping should only be considered where the construction and supporting evidence allow the proposed method. Do not specify a universal repair or gap limit for every door; use the applicable doorset information, including its threshold and smoke-seal detail.

Record where the gap occurs and investigate its cause
Consider the frame and surrounding construction
Confirm evidence for any alteration to the leaf or frame

When replacement or further assessment is needed

Widespread damage, incompatible alterations or an unsupported repair may make replacement the appropriate option. Uncertain evidence may require further assessment before either route can be agreed. Missing identification does not by itself settle the replacement decision: Government guidance recognises that existing doors can remain in use where suitable and effective. Equally, age or familiarity is not proof of adequate performance. Document the decision and any unresolved information.

Explain why the proposed repair is supported - or why it is not
Identify investigations or information still needed
Check the replacement specification before ordering

Compare the complete scope, then record the result

Compare quotations on the same basis: investigation, components, access, making good, final checks and the documents to be supplied. Agree how additional defects will be authorised if discovered on site. At completion, keep the original finding, work description, photographs and recorded outcome under the same door reference. FireX can review an existing report and advise whether an on-site survey is needed to define a reliable scope.

Confirm the documentation applicable to the work
Keep unresolved defects on the action schedule
