A fire door that is wedged open, badly adjusted or fitted with unsuitable hardware may look like a minor maintenance issue. In a fire, it can allow smoke and flames to spread through a building far more quickly than intended. The best practices for fire door maintenance therefore need to be part of normal premises management, not a task left until an inspection identifies a fault.
For duty holders, the aim is straightforward: make sure each fire door can close, latch and perform as part of the building’s fire safety strategy. That requires planned checks, competent repairs and clear records, while keeping disruption to staff, residents, pupils, patients or visitors to a minimum.
Understand the duty holder’s responsibility
Fire doors are a critical part of passive fire protection. Unlike an alarm or extinguisher, they work by containing fire and smoke within a compartment, protecting escape routes and buying occupants valuable time to leave safely.
Under the Regulatory Reform (Fire Safety) Order 2005 in England and Wales, the responsible person must take general fire precautions and maintain measures provided to safeguard relevant persons. Fire doors should be considered within the fire risk assessment, alongside escape routes, alarm systems, emergency lighting and fire-fighting equipment. Scotland and Northern Ireland have separate fire safety legislation, but the need for suitable inspection and maintenance remains.
The level and frequency of attention should reflect the premises, the door location, how heavily it is used and the people at risk. A busy corridor door in a school, care setting or shared office is likely to need closer monitoring than a rarely used plant room door. Where fire doors form part of a residential building’s common areas, further duties may apply under the Fire Safety (England) Regulations 2022.
Best practices for fire door maintenance start with a register
A fire door register gives a site team and its contractors a clear baseline. It should identify every fire-resisting door, its location, its likely rating where known, its function and the results of previous checks. Numbering doors is particularly useful on larger sites, multi-occupancy buildings and estates with several blocks.
The register should not rely on assumptions. A door may look substantial but not be a certified or suitable fire door assembly. Conversely, an older door may still provide the required protection if it has been assessed and maintained correctly. Where there is uncertainty over a door’s specification, construction or rating, seek competent advice rather than recording unverified information.
A planned programme should also distinguish between routine visual checks by trained on-site staff and more detailed inspections by a competent fire door inspector. Day-to-day checks catch obvious problems quickly. Periodic professional inspection provides a more thorough assessment of the door, frame, seals, glazing, hinges, closer and ironmongery.
Set inspection intervals based on risk
There is no single inspection interval that suits every building. A fire risk assessment and the door’s use should guide the schedule. As a practical approach, many commercial premises arrange detailed fire door inspections at least every six months, with more frequent checks for doors subject to heavy use or higher risk.
Routine site checks can be carried out monthly or more often where conditions demand it. A door that is used hundreds of times a day deserves more attention than one that is normally kept closed and only accessed by authorised maintenance staff. Any report of impact damage, a failed closer or an alteration to nearby works should trigger an additional check.
Check the door as a complete assembly
A fire door is not just the leaf. Its performance depends on compatible components working together. Replacing a closer, lock, hinge or vision panel with a non-fire-rated alternative can compromise the assembly, even when the door itself appears undamaged.
During a routine inspection, look for the following issues:
- The door should close fully into the frame from any open position and engage positively with the latch where fitted.
- The self-closing device should operate smoothly, without slamming, sticking or needing assistance to shut the door.
- Intumescent strips and smoke seals should be present where required, securely fitted and free from paint, damage or excessive gaps.
- Hinges, handles, locks, latches and closers should be secure, suitable for the door and show no significant wear or missing screws.
- The door leaf, frame and glazing should be free from holes, splits, warping, loose beading and unauthorised alterations.
- Gaps around the door should be consistent and within the limits appropriate to its tested or assessed design. Excessive gaps can permit smoke and hot gases to pass.
The practical test is often revealing. Open the door fully, then release it. It should close under the power of its closer, without catching on flooring, carpets or the frame, and should latch without someone pushing or pulling it into place. If it does not, record the fault and arrange repair promptly.
Repair faults with compatible materials and competent workmanship
Fire door repairs are not general joinery work. A well-meaning repair can create a serious compliance issue if it involves trimming too much from the leaf, drilling holes for unsuitable hardware, filling damage with inappropriate materials or changing the closer without checking compatibility.
Use contractors who understand fire door assemblies and can explain the scope of repair. For more substantial works, such as replacing a leaf, frame, glazing system, seals or ironmongery, the specification should be checked against the door’s evidence of performance or a competent assessment. Where replacement is necessary, consider the whole assembly rather than fitting a new leaf into an unsuitable existing frame.
Do not postpone defects simply because a door still looks presentable. A failed self-closer, damaged smoke seal or door that will not latch affects the very function the door is there to provide. Temporary controls may be appropriate while repairs are arranged, but they should be documented and reviewed rather than becoming a permanent workaround.
Prevent everyday misuse and damage
Many fire door failures are caused by ordinary building activity. Door wedges, bins, furniture, delivery trolleys and loose cabling can all stop a door from closing. Decorations, notices and signs may conceal damage or interfere with seals, while repeated impacts can loosen closers and hinges.
Staff awareness is a practical control. People should understand that fire doors must not be wedged open and that a door which does not close properly must be reported. If a location genuinely needs to remain open for operational reasons, seek suitable advice on compliant hold-open solutions linked to the fire alarm system. A wedge or improvised restraint is never an acceptable substitute.
Facilities teams should also consider how cleaning, refurbishment and access work affect doors. New flooring can cause a door to drag. Repainting can cover smoke seals. Security changes may introduce incompatible locks or access-control equipment. Bringing fire door checks into the planning stage of these works prevents avoidable remedial costs later.
Keep records that support compliance decisions
Good records demonstrate that faults have been identified, prioritised and addressed. They also make recurring problems easier to spot, such as a particular doorway repeatedly being struck by deliveries or a closer that is being adjusted without resolving the underlying issue.
For each inspection, retain the door reference, date, inspector, findings, photographs where helpful, recommended actions, repair completion date and any outstanding risk. Records should be accessible to the responsible person and available when reviewing the fire risk assessment.
Competence matters as much as documentation. On-site staff can be trained to identify obvious defects, but detailed assessment and repair should be undertaken by people with suitable knowledge, experience and qualifications. This is especially relevant where a defect may affect a door’s fire or smoke performance. DBS-cleared, qualified engineers can also be a sensible requirement for schools, healthcare settings and occupied residential environments.
Coordinate fire doors with the wider fire safety plan
Fire door maintenance works best when it is coordinated with the site’s wider compliance schedule. Fire risk assessment findings, fire extinguisher servicing, alarm testing and emergency lighting checks can reveal changes to occupancy, layouts and escape routes that affect the condition or importance of particular doors.
For example, a storage area converted into an office, a revised evacuation route or a change in occupant vulnerability may alter the risk associated with a door. Reviewing this information together helps the responsible person prioritise action appropriately rather than treating each compliance task in isolation.
Janus Safety Solutions can support organisations with practical fire door inspections planned around the site, its working hours and its safety responsibilities. The objective is not to create unnecessary disruption, but to provide clear findings and workable actions for maintaining safer premises.
A fire door only protects people when it is able to close and contain fire at the moment it is needed. Making checks routine, acting promptly on defects and using competent support turns that requirement into a manageable part of day-to-day compliance.
