Fire Door Maintenance in Norwich and throughout Norfolk – SAB Group

Effective fire door maintenance involves much more than checking whether a door still opens and closes. It requires a competent understanding of how a certified fire door assembly is supposed to function and how wear, damage, or incompatible alterations can affect its fire performance.

SAB Group’s fire door maintenance service includes checking the condition and serviceability of all major fire door components, including:

• Fire door leaves
• Frames and frame alignment
• Intumescent seals and smoke seals
• Hinges and fixings
• Self-closing devices
• Latches, locks, and other ironmongery
• Fire-rated glazing and glazing systems
• Signage
• Thresholds and clearances
• Fire door retainers and associated hardware

Where faults are identified, we carry out remedial works and repairs in line with industry-approved methods and manufacturer guidance wherever possible. Our aim is always to restore compliance and performance in the most practical and cost-effective way.

SAB Group carries out planned and reactive fire door maintenance across commercial, residential, healthcare, education, industrial, and public sector environments.

Our fire door maintenance services include:

• Routine planned preventative maintenance
• Remedial works following fire door inspections
• Reactive fire door repairs
• Replacement of worn or damaged seals, hinges, and ironmongery

• Ongoing support as part of wider passive fire protection strategies

We inspect and maintain all types of fire doors, including FD30 fire doors, FD60 fire doors, internal fire doors, external fire doors, and fire door retainers.

Fire doors should be maintained according to their level of use, location, risk profile, and the environment they are exposed to. Doors in high-traffic or high-risk areas will generally require closer attention than those in less demanding locations.

In practice, regular monthly in-house checks can help identify visible faults early, while formal maintenance by a competent specialist should be carried out whenever defects are found and as part of a planned maintenance strategy.

Maintenance should not be treated as a one-off response to failure. A structured programme helps keep doors operational, reduces disruption, and ensures that issues are resolved before they affect fire safety performance.

Many fire doors fail not because the original door leaf was unsuitable, but because the complete assembly has not been maintained properly over time.

Common maintenance-related issues include:

• Excessive gaps between door and frame
• Worn, damaged, or missing seals
• Poorly performing self-closing devices
• Loose or damaged hinges
• Non-compliant replacement ironmongery
• Damaged glazing or glazing beads
• Unauthorised alterations
• Doors being wedged or held open incorrectly
• General wear and impact damage

These issues are often straightforward to correct when identified early. A proactive maintenance approach helps avoid larger compliance failures and preserves the performance of the existing door set.

The cost of fire door maintenance depends on the number of doors involved, the type and extent of defects, the age and condition of the assets, and whether the work is planned or reactive.

In many cases, regular maintenance is significantly more cost-effective than allowing defects to worsen until complete replacement becomes necessary. Planned maintenance also helps reduce disruption, improve budgeting, and keep buildings compliant over time.

SAB Group takes a practical approach focused on restoring serviceability, extending asset life, and reducing avoidable replacement costs wherever possible.
