Introduction
Fire doors are often described as the “silent guardians” of a building. They sit unnoticed in corridors, stairwells, and entryways, performing their day-to-day function like any other door. But in the event of a fire, their importance becomes crystal clear. A well-maintained fire door can mean the difference between safe evacuation and tragedy.
At Guardian Shield Doors, we understand that manufacturing and installing certified fire doors is only part of the journey. To continue performing their life-saving role, fire doors need consistent, expert maintenance. Just as a car requires servicing to stay roadworthy, fire doors must be inspected, repaired, and maintained to remain compliant and effective.
This article explores why ongoing maintenance is essential, which components require regular attention, what common faults arise over time, and how preventative strategies ensure fire doors achieve maximum lifespan and safety.
Why Fire Door Maintenance Matters
A Legal and Moral Responsibility
UK building regulations require fire doors to be kept in good working order. Failure to maintain them not only risks non-compliance — with potential legal and financial consequences — but also endangers lives.
For organisations in social housing, public sector, and commercial property management, fire door maintenance is more than a statutory duty. It is a moral responsibility to protect residents, staff, and the public.
The Hidden Dangers of Neglect
When a fire door is installed, it has been tested and certified to resist fire for a specific time (FD30, FD60, FD90, or FD120). But that rating only applies if the door and its components remain in their original, tested condition.
A missing seal, loose hinge, or faulty closer may seem minor in daily use. Yet in an emergency, these defects can allow smoke and flames to spread rapidly, undermining the entire fire protection strategy of a building.
Key Components That Require Maintenance
Fire doors are complex systems, not just single units. Each element plays a role in ensuring the door achieves its fire rating. Regular inspection and maintenance of the following components is essential.
- Hinges
Hinges support the weight of the door and ensure it closes properly. Over time, they can loosen, corrode, or even become damaged by repeated heavy use.
- What to check: Screws should be tight, hinges should be free from oil leakage or distortion, and there should be no visible cracks.
- Prevention: Use only certified fire-rated hinges and schedule routine tightening or replacement.
- Closers
Closers ensure that fire doors shut automatically, sealing off a fire compartment. A door left ajar is effectively useless in an emergency.
- What to check: The door should close firmly onto the latch from any position without slamming. Resistance should be smooth, without sticking or jerking.
- Prevention: Adjust closers regularly and replace any that are leaking or failing to control the door’s motion.
- Intumescent & Smoke Seals
Seals are designed to expand under heat, blocking the passage of smoke and flames. Over time, they can wear down, become damaged, or even be painted over.
- What to check: Ensure seals are continuous, unbroken, and free from damage. They must not be obstructed by paint or adhesives.
- Prevention: Replace damaged seals immediately and educate maintenance teams about correct repainting practices.
- Door Leaves & Frames
The leaf and frame must fit correctly. Excessive gaps can allow smoke to bypass the door, reducing its effectiveness.
- What to check: The gap should be consistent (generally 2–4mm). Warping, swelling, or damage must be addressed quickly.
- Prevention: Use correct installation techniques and monitor environmental conditions like humidity that affect timber.
- Ironmongery (Handles, Locks, Latches)
Handles and locks not only serve everyday functionality but also ensure a door remains securely closed during a fire.
- What to check: All components should operate smoothly, without sticking or wobbling.
- Prevention: Use only certified ironmongery tested with the door set. Replace faulty parts promptly.
Common Faults That Arise Over Time
Guardian Shield Doors has worked across countless properties, and we consistently see recurring issues that compromise fire door performance.
- Doors wedged open – A common shortcut in busy environments like offices or hospitals. This completely undermines the door’s purpose.
- Worn or missing seals – Often overlooked but critical for smoke containment.
- Damaged hinges – Heavy use can loosen screws, leading to misalignment.
- Non-compliant replacements – Using uncertified components during repairs.
- Poor closing action – A closer that doesn’t shut the door properly leaves a dangerous gap.
- Warped or damaged door leaves – Especially in high-traffic housing blocks where impact damage is frequent.
Preventing Issues: A Proactive Approach
Regular Inspections
Fire doors should be checked at least every six months, or more frequently in high-use areas. Guardian Shield Doors recommends quarterly checks for social housing communal doors and monthly checks for hospitals or schools.
Trained Inspectors
Inspections must be carried out by competent personnel with knowledge of fire door regulations. Our trained teams use detailed checklists to spot even minor issues.
Scheduled Maintenance Plans
Rather than waiting for faults to arise, proactive maintenance ensures longevity. Guardian Shield Doors offers structured maintenance packages to reduce downtime and spread costs.
Education & Awareness
Residents, tenants, and staff need to understand why fire doors must not be wedged open or tampered with. Simple awareness campaigns can reduce misuse dramatically.
Case Studies in Repair & Maintenance
Housing Association – Large-Scale Door Servicing
A housing association responsible for 500 residential units asked Guardian Shield Doors to assess the condition of their fire doors. Inspections revealed worn seals, loose hinges, and several non-compliant repairs from previous contractors. Our team replaced components, restored compliance, and implemented a long-term maintenance plan. Result: improved resident safety and reduced legal exposure for the client.
Commercial Office Block – High-Traffic Repairs
In a busy London office building, frequent use had caused several fire doors to misalign, preventing proper closing. Guardian Shield Doors carried out targeted repairs, replacing faulty closers and reinforcing hinges. The client passed their next fire inspection without issue.
Hospital Environment – Continuous Monitoring
Hospitals present unique challenges with high footfall and accessibility requirements. Guardian Shield Doors provided a rolling maintenance programme, ensuring fire doors were checked and repaired monthly. This proactive approach helped maintain critical safety standards in a demanding environment.
