Fire Door Replacement Surveys for Commercial Buildings

A door can look sound and still fail to close when it matters. In an occupied commercial building, worn hinges, a damaged frame or a new floor covering can change how a fire door works.

A fire door survey gives you a door-by-door record before you commit to replacement. It helps you separate repairable faults from doors that need further investigation or renewal, so you can plan the work around people using the building.

Why survey before replacing fire doors?

Match the decision to the building’s fire risk

In England, the Regulatory Reform (Fire Safety) Order 2005 places fire safety duties on the person responsible for non-domestic premises. That person needs to assess risks and maintain appropriate precautions. A survey provides evidence to support decisions about the doors that protect escape routes and fire compartments.

Start with the building’s fire risk assessment and fire strategy, where available. A door on a protected stair may have a different role from one between back-of-house rooms. Its required performance cannot be established from appearance alone.

Avoid replacing the wrong part

A new leaf won’t solve a distorted frame or a damaged opening. Likewise, replacing a closer without checking the latch may leave a door that still won’t shut properly.

The survey should establish what is fitted, what has failed and what evidence exists for the door assembly. Only then can the specification identify whether to retain, repair or replace it. This matters especially in older buildings, where several generations of doors and hardware may sit along the same corridor.

What a fire door survey should check

A useful inspection follows the complete assembly and records each door by location. It also checks the surrounding construction where a visible defect could affect how the door fits.

Leaf, frame and surrounding opening

The inspector looks for splits, warping, impact damage and previous cut-outs. Glazing, vision panels and any fitted grilles need attention too. A replacement pane or grille cannot be assumed suitable because it fits the opening.

Frame movement matters as much as leaf damage. The survey should note loose fixings, a damaged rebate, gaps between the frame and wall, and signs that the opening has changed. Architraves may conceal parts of the installation, so the report should distinguish what was seen from what still needs investigation.

Seals, gaps and closing action

Intumescent strips and smoke seals should be checked for missing lengths, paint, tears and poor contact. The inspector measures relevant perimeter gaps and checks the threshold, particularly where carpet or vinyl has been changed.

Government fire-door guidance cites 4 mm as an industry-standard maximum gap at the sides and top, but the applicable door specification must guide the assessment. Closing tests should show whether the leaf shuts and latches from fully open and from a position close to the frame, around 15 degrees. Hinges, closer, latch and any hold-open device all affect that result.

How survey findings lead to a replacement decision

A failed check does not automatically condemn a door. The next step is to identify the defect, the door’s required role and whether an evidenced repair can restore suitable performance.

Retain or repair where the evidence supports it

A loose fixing or faulty closer may be repairable with a compatible part and appropriate workmanship. The survey should state the fault and recommend verification after the work, rather than recording a vague “pass” or “fail”.

For example, “leaf stalls before latching after new carpet was fitted” tells the repairer more than “closer defective”. It also points the building manager towards a follow-up closing test once the flooring issue is resolved.

Replace when condition or compatibility rules out repair

Extensive leaf damage, a compromised frame or repeated failed repairs may make replacement the sensible option. Missing technical information can also require further investigation before anyone claims an older door has a particular fire-resistance rating.

A replacement leaf is only one part of the decision. The frame, hardware, seals and installation all need to suit the proposed assembly.

Record uncertainty clearly. If a label is missing or the construction is concealed, the surveyor should not assign a rating based on thickness or appearance.

Specify the right replacement for the opening

A replacement should reflect the building’s fire strategy, the door’s use and the evidence available for the proposed product. Fire-resistance and smoke-control requirements need to be confirmed for that location, rather than copied from the nearest door.

Treat the doorset as a matched assembly

Check the specified leaf, frame, glazing, seals, hinges, latch and closer together. If there are access-control devices or hold-open equipment, their compatibility also needs review. Manufacturer instructions and supporting test evidence should inform the choice of components and installation details.

Approved Document B for buildings other than dwellings gives practical guidance on Building Regulations requirements. It is relevant when planning building work, but it does not replace the fire risk assessment for an occupied premises.

Distinguish escape doors from fire-resisting doors

A final exit must allow people to escape readily. A fire-resisting door is intended to protect an escape route or compartment by resisting fire, and sometimes smoke, for the required period. Some doors must do both jobs.

This distinction matters at commercial entrances and service areas. A security shutter is not automatically a fire door, and a fire exit door specification must account for emergency use. If an opening serves both security and escape needs, discuss both functions before ordering. UK Doors & Shutters offers fire exit door surveys and quotations for businesses planning an installation.

Turn the survey into a workable replacement plan

A survey is most useful when the facilities team can act on it without returning to identify every opening again. Photographs, door references and clear recommendations reduce confusion when several contractors or shifts share a site.

Record each door and its priority

The report should identify the location, door type where known, observed defects and the action proposed. It should also state whether evidence was available to verify the existing assembly. Photographs can show a damaged hinge edge, failed seal or obstruction more clearly than a short note.

Prioritise doors by the risk presented, not simply by how worn they look. A door that fails to close on a protected route needs prompt attention. Cosmetic damage elsewhere may have a different priority, although it still needs assessment.

Quote for the whole job

Replacement costs depend on the specified assembly, opening size, glazing, access equipment and condition of the surrounding wall. Disposal, making good and work outside trading hours can also affect a quotation.

Ask whether the proposal includes frame work, compatible hardware, installation and final testing. That makes comparisons more meaningful than a price for the leaf alone. A free installation site survey can help establish measurements and scope, but it should not be confused with a documented fire-door inspection.

Plan installation around an occupied building

In a working office, hospital, shop or factory, access arrangements are part of the job. Agree which openings will be unavailable, how staff will move through the building and when noisy or dusty work can take place.

Keep escape arrangements effective during the work. If a door is removed from a protected route, the responsible person and installer should agree suitable temporary precautions before work starts. Do not leave an opening unprotected or assume a closed roller shutter solves the problem.

After installation, check that each leaf closes and latches, seals meet as intended and access devices operate correctly. Give the building manager the product and installation information needed for future maintenance. Where the replacement changes the building’s arrangements, review the fire risk assessment and relevant records.

Keep replacement doors working after handover

Traffic, trolleys and changes to flooring can alter a door’s operation long after installation. Staff should know how to report a door that drags, slams, sticks or fails to latch. They should not wedge it open or make improvised hardware adjustments.

There is no single statutory inspection interval for every commercial fire door. Set a suitable schedule using the risk assessment, manufacturer information, door usage and site conditions. Also arrange a check after impact damage, alterations or repeated complaints. London Fire Brigade’s property-management guidance explains why doors must remain effective in use, while planned fire door maintenance and testing helps identify faults before they persist.

Key takeaways

• Survey the leaf, frame, opening, seals and hardware before deciding what to replace.
• Record each defect against a door location, with photographs and a clear action.
• Specify compatible components for the door’s required fire, smoke and escape functions.
• Test the completed installation, then maintain it according to the building’s risks and use.

Frequently asked questions

Does every damaged commercial fire door need replacing?

No. A competent assessment may find that a compatible repair can address a particular defect. Replacement becomes more likely when the leaf or frame is extensively damaged, the required performance cannot be supported, or a suitable repair is not available. The report should explain the recommendation and any uncertainty.

How often should commercial fire doors be inspected?

The interval for an ordinary commercial premises should follow its fire risk assessment, door usage and manufacturer guidance. A heavily used warehouse door may need closer attention than a lightly used office door.

Do not apply the residential inspection timetable to every workplace. The government’s fire-door fact sheet covers additional duties for relevant residential buildings in England, including checks of communal doors at least every three months and best-endeavours annual checks of flat entrance doors in buildings over 11 metres.

Can we fit a new leaf into the existing frame?

Possibly, but only after checking whether the frame, dimensions, fixings, seals and hardware suit the proposed leaf and its supporting evidence. A sound-looking frame is not proof of compatibility. A survey should establish whether retaining it is a defensible option or whether the opening needs a complete replacement assembly.

Is a free site survey the same as a fire-door compliance inspection?

No. An installation visit can establish access, measurements and a proposed scope of work. A documented fire door survey should also record condition, function, defects and the evidence behind recommendations. Tell the provider which type of assessment you need and whether you require a door-by-door report.

Conclusion

A door that looks sound may still fail the closing test. That is why a door-by-door survey should come before a commercial replacement programme.
