This content does not constitute legal, regulatory, or technical advice for your specific circumstances. Always consult qualified fire safety professionals, FIRAS-certified installers, and relevant authorities before making decisions about fire door specification, installation, or maintenance.

Like smoke alarms and fire extinguishers, fire doors require regular inspection and maintenance to perform when lives depend on them. Yet unlike these more obvious safety devices, fire door maintenance is often overlooked until problems arise. Our decades of experience across Lancashire’s schools, hospitals, and commercial buildings have taught us that proactive fire door maintenance prevents both safety risks and costly emergency repairs.
Legal Requirements: What the Law Demands
The Regulatory Reform (Fire Safety) Order 2005 places clear legal obligations on responsible persons to ensure fire doors are “correctly installed and adequately maintained.” This isn’t merely guidance – it’s enforceable law with serious penalties for non-compliance.
For buildings over 11 metres in height, the Fire Safety (England) Regulations 2022 specify minimum inspection frequencies:
- Flat entrance fire doors: At least every 12 months
- Common area fire doors: At least every 3 months
- High-use doors: Monthly or even weekly inspections
These are minimum requirements. Our experience suggests that newly occupied buildings, areas with heavy foot traffic, or doors in challenging environments benefit from more frequent checks.
The A&H Hargreaves 8-Point Inspection System
Drawing on our FIRAS certification training and decades of practical experience, we’ve developed a comprehensive inspection approach that goes beyond basic compliance:
Certification and Labelling Verification
Every genuine fire door carries identification proving its certification status. Look for labels or plugs indicating:
- Fire resistance rating (FD30, FD60, etc.)
- Manufacturer details
- Certification body approval
- Installation date where applicable
Red flags: Missing labels, handwritten modifications, or unofficial markings suggesting unauthorised alterations.
Gap Measurements and Tolerances
Gap tolerances are critical for fire door performance:
- Perimeter gaps: Maximum 4mm when door is closed
- Threshold gap: Usually 8mm maximum (can vary by manufacturer)
- Consistent gaps: No significant variations around the perimeter
Inspection tip: Use a £1 coin (3mm) as a quick gauge. If it fits easily in perimeter gaps, closer inspection is needed.
Intumescent and Smoke Seal Assessment
Seals are often the first component to fail through wear or damage:
- Check for continuous coverage around door frame
- Look for splits, tears, or missing sections
- Ensure seals haven’t been painted over or compressed
- Verify smoke seals (where fitted) are intact and properly positioned
Common problems: Paint build-up from decorating, damage from cleaning equipment, or compression from heavy door use.
Hardware and Ironmongery Inspection
All hardware on fire doors must be certified for fire door use:
- Hinges: Check all screws are present and tight (minimum 3 hinges on FD30 doors)
- Locks and latches: Ensure proper operation and fire certification
- Handles and hardware: Verify fire door certification markings
- Vision panels: Check for impact damage and proper sealing
Safety note: Standard ironmongery cannot be substituted for fire door hardware without compromising certification.
Door Closer Function and Adjustment
Self-closing mechanisms are mandatory on most fire doors:
- Door should close fully without assistance
- Closing speed should allow safe passage
- Check for oil leaks or mechanical wear
- Verify closer arm connections are secure
Adjustment requirements: Door closers may need seasonal adjustment as building air pressures change with heating and ventilation systems.
Structural Integrity Assessment
Examine both door leaf and frame for:
- Warping, splitting, or impact damage
- Loose joints in door construction
- Frame damage or movement
- Signs of water damage or rot (timber doors)
Professional assessment needed: Structural damage often requires expert evaluation to determine whether repair or replacement is necessary.
Glazing and Vision Panel Checks
Fire-rated glazing requires specific attention:
- Look for cracks, chips, or impact damage
- Check glazing compound or beading is intact
- Verify fire rating matches door rating
- Ensure glazing size doesn’t exceed certified limits
Replacement requirements: Fire-rated glazing must be replaced with identical or superior rated products.
Environmental Factors and Positioning
Consider the door’s operating environment:
- Check for obstructions preventing full closure
- Assess impact from cleaning equipment or trolleys
- Look for unauthorised modifications (door stops, holders, etc.)
- Evaluate exposure to moisture, chemicals, or extreme temperatures
Frequency Guidelines Based on Usage
Low Traffic Areas (Storage, Plant Rooms)
- Quarterly visual inspections
- Annual comprehensive assessment
- Immediate response to any obvious damage
Medium Traffic Areas (Office Corridors, Stairwells)
- Monthly visual checks
- Quarterly detailed inspections
- Semi-annual comprehensive assessment
High Traffic Areas (School Corridors, Hospital Wards)
- Weekly visual inspections
- Monthly detailed checks
- Quarterly comprehensive assessments
Critical Areas (Means of Escape Routes)
- Daily visual checks during normal building operations
- Weekly detailed inspections
- Monthly comprehensive assessments
Documentation and Record Keeping
Proper documentation serves multiple purposes:
- Legal compliance: Demonstrating due diligence to authorities
- Insurance requirements: Supporting claims and coverage
- Maintenance planning: Tracking patterns and predicting needs
- Budget planning: Anticipating replacement schedules
Essential Records
- Inspection dates and findings
- Maintenance actions taken
- Parts replaced with certification details
- Inspector qualifications and training records
- Photographic evidence of conditions
Common Problems and Solutions
Doors Not Closing Properly Often caused by worn door closers, warped frames, or accumulated paint on seals. Solutions range from closer adjustment to professional realignment.
Damaged or Missing Seals Usually results from impact damage or cleaning practices. Replacement seals must match original specifications exactly.
Hardware Failures Worn handles, loose hinges, or failed locks compromise both security and fire performance. All replacements must carry fire door certification.
Unauthorised Modifications Well-meaning modifications like additional vision panels or ventilation grilles can void fire door certification entirely.
The Lancashire Advantage: Local Expertise
Our experience across Lancashire’s diverse building stock – from Victorian mills converted to modern offices to purpose-built schools and hospitals – provides unique insights into fire door maintenance challenges. Climate conditions, building movement, and usage patterns all affect fire door performance differently.
We’ve developed maintenance programmes tailored to specific building types and usage patterns. Schools require different approaches than offices, whilst heritage buildings need specialist attention to balance conservation requirements with fire safety compliance.
When to Call Professionals
Whilst building managers can perform basic inspections, certain situations require professional intervention:
- Structural damage to doors or frames
- Seal replacement or adjustment
- Hardware installation or replacement
- Certification queries or compliance concerns
- Integration with building management systems
Our FIRAS certification means we can provide both maintenance services and compliance documentation that satisfies regulatory requirements and insurance conditions.
The Cost of Neglect
Poor fire door maintenance creates multiple risks:
- Life safety: Compromised protection during emergencies
- Legal liability: Prosecution under fire safety legislation
- Insurance implications: Potential coverage issues following incidents
- Financial costs: Emergency repairs cost significantly more than planned maintenance
