Repair vs Replacement
Practical guidance for assessing when fire doors may be repaired, conditionally repaired or require full replacement.
Introduction
One of the most significant challenges within existing buildings is determining whether a fire door defect requires full replacement or may be practically repaired.
In many cases, automatic replacement assumptions can result in significant cost escalation, unnecessary waste and disruption to building operations.
This guidance promotes practical, evidence-based and proportionate approaches to assessing repair viability while maintaining focus on fire and smoke performance outcomes.
Core Principle
Not every fire door defect automatically requires full door replacement.
Fire doors should be assessed based on:
- Extent of damage
- Impact on fire resistance performance
- Impact on smoke control performance
- Door operation and latching
- Structural integrity
- Repair practicality
- Availability of supporting evidence
- Long-term maintainability
Potentially Repairable Conditions
The following conditions may be capable of practical repair depending on severity, location, repair methodology and supporting evidence.
Repair decisions should be informed by structured Defect Classification methodologies together with operational performance, smoke control and available supporting evidence.
In some situations, practical Repair Methods may provide proportionate remediation pathways for existing buildings.
Surface Damage
- Minor dents and impact damage
- Surface scratches
- Paint deterioration
- Localised laminate damage
Hardware Defects
- Failed closers
- Loose hinges
- Latch adjustments
- Damaged handles or locks
Seal Replacement
- Damaged smoke seals
- Perished intumescent seals
- Localised seal deterioration
Minor Edge Repairs
- Localised edge damage
- Minor frame separation
- Small penetrations
Conditions Likely Requiring Replacement
Certain defects may significantly compromise the structural integrity or fire performance of the doorset and may not be practically repairable.
- Severe structural damage
- Extensive delamination
- Major warping or twisting
- Non-compliant door construction
- Extensive unauthorised modifications
- Severe frame failure
- Loss of positive latching capability
- Extensive glazing failure

Practical Position
Existing buildings often contain legacy fire door systems with varying construction methods, undocumented modifications and ageing components.
Practical repair methodologies may provide proportionate and maintainable outcomes where replacement is not immediately practical or commercially achievable.
Repair decisions should be supported by documented assessment processes, repair evidence and ongoing maintenance considerations.
