Fire door hardware plays a critical role in the overall performance of a fire-rated door assembly. While product selection and certification often receive significant attention, regular inspection and ongoing maintenance are equally essential to ensure that fire door hardware continues to function as intended throughout its service life.
In public buildings such as airports, schools, hospitals, and commercial facilities, improperly maintained fire-rated door hardware can compromise fire compartmentation, delay evacuation, and lead to non-compliance with fire safety regulations.
This article provides a practical overview of how fire door hardware should be inspected and maintained from a lifecycle and compliance perspective, helping building owners and facility managers reduce risk and maintain long-term performance.
Fire-rated door hardware is designed and tested to perform under extreme conditions. However, certification alone does not guarantee long-term performance if the hardware is incorrectly installed, modified, or poorly maintained during use.
Regular inspection and maintenance help to:
Ensure that fire doors self-close and latch correctly
Maintain the integrity of certified locking and latching mechanisms
Reduce operational failures caused by wear, misuse, or unauthorized component replacement
Support compliance with applicable fire safety regulations and building codes
In many jurisdictions, building owners and facility managers are legally responsible for ensuring that fire doors and their hardware remain functional throughout the building’s lifecycle—not only at the point of installation.
A complete fire door hardware inspection should include, but is not limited to, the following components.
• Verify that the latch bolt fully engages into the strike plate
• Ensure smooth operation without binding or excessive resistance
• Check that all fixing screws are present and securely tightened
• Inspect for the presence of dust, debris that may affect performance
• Confirm that the mortise lock bears a valid CE marking
• Verify that no non-certified internal components have been replaced
• Verify that lever handles return fully to their horizontal position after operation
• Confirm that the latch bolt re-engages smoothly and completely with the strike plate
• Inspect for excessive looseness, sagging, or signs of spring fatigue
• Ensure that fixing screws and mounting points remain secure
• Confirm that the lever handle is compatible with the door’s fire rating and locking system
• Confirm correct key or thumbturn operation from both sides of the door
• Check for signs of wear, misalignment, or damage caused by forced entry
• Verify that the profile cylinder length, configuration, and function remain unchanged from the certified specification
• Verify that all fixing screws are present and securely fastened
• Check for hinge misalignment or door sagging that may cause uneven gaps or binding
• Perform an open-and-close test to ensure smooth operation without abnormal noise
• Inspect hinge leaves and knuckles for wear, deformation, cracks, corrosion, or mechanical damage. Pay particular attention to pivot points subject to frequent operation and load
• Ensure hinges are compatible with the door’s fire rating and bear appropriate CE marking
• Verify that all fixing screws are present and the closer body and arm are securely installed
• Inspect for signs of oil leakage or visible damage to the housing
• Ensure the door closes fully from any open position
• Verify correct closing speed and latching action, ensuring controlled movement without slamming or hesitation
• Confirm that the door closer bears a valid CE marking
• Confirm immediate and unobstructed operation under emergency pressure
• Ensure that all latching points fully retract when the device is activated
• Verify that no additional locking devices or unauthorized modifications have been added
• Confirm that the device bears a valid CE marking and remains consistent with the certified configuration

Fire door hardware does not function in isolation. Its performance is directly linked to the condition of the door leaf, frame, and sealing system. During hardware inspection, the following elements should also be reviewed to ensure overall system integrity:
Fire door leaf and frame
Check that the door leaf and frame are free from significant deformation, penetration damage, or structural defects. Fire rating labels and identification marks should remain clearly visible and legible.
Intumescent seals
Inspect intumescent seals to ensure they are continuous, intact, securely fixed, and free from excessive wear or deterioration. Damaged or missing seals must be replaced immediately.
Where applicable—particularly on timber fire doors—verify that hardware such as locks and hinges is used in conjunction with appropriate intumescent protection as required by the door’s fire test evidence.
Maintenance principles for fire door hardware
Any issues identified during inspection should be addressed promptly through proper maintenance. Maintenance activities should follow the hardware manufacturer’s instructions. In general, the following principles apply:
1. Cleaning
Regularly remove dust, dirt, and debris from hardware surfaces using a soft, dry cloth. Avoid abrasive materials or corrosive solvents, as these may damage finishes or coatings.
2. Lubrication
Lubricate latch bolts, hinge pivots, and other moving parts only where recommended. Avoid grease-based lubricants, which tend to attract dust, form residue, and may degrade seals or internal components over time.
3. Tightening and adjustment
Re-tighten any loose fixing screws and ensure all components are securely installed. Door closer closing speed and latching action may be adjusted in accordance with the manufacturer’s guidance, using appropriate tools and without applying excessive force.
4. Replacement
Components showing functional failure, excessive wear, deformation, or damage must be replaced without delay. All replacement parts must match the original specification, fire rating, and certification (e.g. CE marking). The use of non-fire-rated or non-tested generic hardware components is strictly prohibited, as it can invalidate the fire door’s compliance and compromise overall fire performance.
Conclusion
Fire door hardware inspection and maintenance should not be viewed as a one-time compliance task, but as an ongoing responsibility throughout the building’s service life. Even certified and correctly installed hardware may fail to perform as intended if it is neglected, modified, or repaired using non-approved components.
By implementing regular inspections, carrying out timely maintenance, building owners and facility managers can help ensure that fire-rated door assemblies continue to provide reliable compartmentation, safe evacuation, and regulatory compliance when it matters most.
