Fire door inspections are a critical aspect of building safety, yet many properties across Lancashire and the UK continue to fail these essential checks. As FIRAS-certified fire door specialists with over 70 years of experience, we have witnessed firsthand the most common fire door inspection failures and understand exactly how to prevent them.
Understanding why fire doors fail inspections, and more importantly, how to avoid these failures, is crucial for protecting lives, maintaining compliance, and avoiding costly remedial work.
Why Fire Door Inspections Matter
Under Article 17 of the Regulatory Reform (Fire Safety) Order 2005, it’s a legal requirement to ensure that fire-resisting doors are correctly installed and adequately maintained. The Fire Safety (England) Regulations 2022 further emphasise this responsibility, particularly for buildings over 11 metres in height, where fire doors must be checked at least every twelve months for individual domestic premises and every three months for communal areas.
Fire door inspection failures don’t just represent compliance issues – they represent genuine safety risks that could prove catastrophic in an emergency. When properly installed and maintained, fire doors provide crucial minutes for evacuation during a fire, containing smoke and flames that could otherwise spread rapidly throughout a building.
The Most Common Fire Door Inspection Failures
1. Incorrect Gap Tolerances
The Problem: Gap tolerances are one of the most frequent causes of fire door inspection failures. Fire doors require precise gaps around the door frame – typically no more than 3mm around the sides and top, and no more than 8mm at the bottom. Gaps that are too wide allow smoke and flames to pass through, whilst gaps that are too narrow can prevent the door from closing properly.
How to Avoid It: Regular measurement and adjustment of door gaps is essential. Professional installation by FIRAS-certified contractors ensures correct initial fitting, whilst periodic maintenance can address any settling or warping that occurs over time. During routine inspections, look for gaps that appear obviously too wide (you shouldn’t be able to easily see light through the sides or top) or doors that don’t sit flush in their frames. If you notice concerning gaps, have them professionally measured and adjusted.
2. Damaged or Missing Intumescent Seals
The Problem: Intumescent seals expand when exposed to heat, sealing gaps to prevent smoke and fire spread. These seals are frequently damaged by everyday use, painted over during decorating, or simply missing entirely. Damaged seals are immediately obvious during professional inspections and represent a critical safety failure.
How to Avoid It: Inspect seals monthly for damage, gaps, or paint coverage. Replace damaged seals immediately and ensure decorating contractors understand they must not paint over intumescent strips. When refurbishing, always use qualified fire door specialists who understand the importance of maintaining seal integrity.
3. Faulty or Inadequate Self-Closing Mechanisms
The Problem: Self-closing devices ensure fire doors close automatically, but they’re frequently adjusted, removed, or allowed to deteriorate. Common issues include closers that don’t fully close the door, have been wedged open, or lack sufficient force to overcome door resistance. The Fire Safety (England) Regulations 2022 specifically require checks to ensure self-closing devices are working.
How to Avoid It: Test self-closing mechanisms monthly by opening each fire door and ensuring it closes fully without assistance. Adjust closing force if doors don’t latch properly, but ensure they still comply with accessibility requirements. Never prop fire doors open with wedges or other makeshift devices – use proper magnetic hold-open systems where required.
4. Incorrect or Substandard Hardware
The Problem: Fire door hardware must be tested and certified for use with fire doors. Standard hinges, handles, and locks often cannot withstand fire conditions and will cause inspection failures. Additionally, the wrong number or type of hinges can compromise the door’s performance.
How to Avoid It: Never replace fire door hardware with standard alternatives from DIY stores. Always use FIRAS-certified fire door specialists like A&H Hargreaves for any hardware repairs or replacements, as we understand which components are certified for fire door use. If you notice loose handles, squeaky hinges, or doors that don’t close properly, contact us rather than attempting DIY fixes that could compromise the door’s fire rating.
5. Structural Damage and Warping
The Problem: Fire doors that are warped, have damaged edges, or show signs of impact often fail inspections. Even minor damage can compromise the door’s ability to fit properly within its frame, affecting gap tolerances and seal performance.
How to Avoid It: Address any damage immediately, no matter how minor it appears. Regular visual inspections should identify warping, cracks, or impact damage early. Ensure doors are protected during building work and that staff understand the importance of reporting any damage promptly.
6. Glazing Issues
The Problem: Fire-rated glazing within fire doors must maintain its integrity, but it’s often cracked, has failed seals, or has been replaced with non-certified glass. Any glazing issues typically result in immediate inspection failure.
How to Avoid It: Inspect glazing regularly for cracks, gaps in sealing, or signs of deterioration. Only use certified fire-rated glazing for replacements and maintain certificates for all glazed elements. Consider protective films or guards in high-traffic areas to prevent impact damage.
7. Poor Installation Standards
The Problem: Many fire door inspection failures stem from poor initial installation. This includes incorrect frame preparation, inadequate fixing, missing fire-stopping around frames, or failure to follow manufacturer instructions precisely.
How to Avoid It: Always use FIRAS-certified installers who understand the critical importance of precise installation. Ensure all installation work is properly certificated and that any building work around fire doors maintains fire-stopping integrity.
Creating an Effective Fire Door Inspection Checklist
To avoid these common failures, implement a comprehensive inspection routine:
Monthly Checks:
- Visual inspection of door and frame condition
- Test self-closing mechanism
- Check intumescent seals for damage
- Verify gap tolerances using a gap gauge
- Ensure no damage to glazing
- Confirm hardware is secure and functioning
Quarterly Checks (for communal areas):
- Detailed inspection of all components
- Document any wear or maintenance needs
- Check certification labels remain in place
- Verify fire-stopping around frames
Annual Checks (for domestic premises in tall buildings):
- Comprehensive professional inspection
- Detailed reporting of any issues
- Planning of any required maintenance work
The Role of Professional Fire Door Specialists
Whilst regular in-house checks are essential, professional fire door inspections and maintenance by certified specialists ensure compliance and safety. As FIRAS-certified contractors, we bring decades of experience in identifying potential issues before they become inspection failures.
Our approach includes detailed documentation, photographic evidence of any issues, and clear recommendations for remedial work. We also provide ongoing maintenance services to keep fire doors compliant between formal inspections.
Planning Ahead: When to Schedule Fire Door Work
Many fire door inspection failures can be avoided through proactive planning. Schools often use summer holidays for fire door maintenance and upgrades, whilst commercial buildings may schedule work during quieter periods or planned refurbishments.
The key is not waiting for inspection failures to drive action. Regular professional maintenance, combined with diligent in-house monitoring, ensures fire doors remain compliant and effective throughout their operational life.
Ensuring Long-Term Fire Door Compliance
Fire door inspection failures represent serious safety risks that are entirely preventable through proper installation, regular maintenance, and professional oversight. Understanding the common causes of failure – from gap tolerances to hardware issues – enables building managers to implement effective prevention strategies.
At A&H Hargreaves, our FIRAS certification and many years of experience across commercial, educational, and residential sectors means we understand both the regulatory requirements and practical challenges of maintaining fire door compliance. We work with clients to develop maintenance programmes that prevent inspection failures whilst ensuring optimal safety performance.
