What Is The Difference Between Active and Passive Fire Protection?
Commercial Fire Door Replacement Services
Contact our experts for more information.
A compliant and properly functioning fire door is essential to maintaining compartmentation and protecting life in the event of a fire. Over time, fire doors can become damaged, worn, or non-compliant due to building changes, poor installation, or general use. When this happens, a fire door replacement is often the safest and most effective solution.
At Fire Industry Specialists (FIS), we provide professional fire door replacement services for commercial and multi-occupancy buildings across the UK. Whether you require a single replacement or a full programme of fire door replacement across your site, our IFC third-party certified engineers ensure every installation meets the latest UK fire safety standards.

When is fire door replacement required?
Fire doors are subject to regular use and ongoing wear, particularly in high-traffic environments such as offices, residential blocks, healthcare settings, and industrial buildings. Over time, this can compromise their performance.
You may need a replacement fire door if:
- The door is damaged, warped, or no longer closes correctly
- Gaps around the door exceed recommended tolerances
- Intumescent or smoke seals on doors are missing or ineffective
- The door doesn’t meet current fire safety regulations
- There is no certification or traceable evidence of performance
- Building alterations have affected fire compartmentation
In many cases, older doors simply don’t meet modern compliance requirements, making fire door replacement the most practical way to ensure safety and legal compliance.
Fire door replacement vs repair
Not every fire door needs to be replaced. In some cases, repairs can restore performance and compliance. However, it’s important to understand when repair is no longer suitable.
A fire door may be repaired if:
- Minor issues, such as seals, hinges, or closers, need to be replaced
- The door leaf and frame are still structurally sound
- The original certification remains valid
A full fire door replacement is usually required if:
- The door is heavily damaged or altered
- Certification is missing or cannot be verified
- The door set doesn’t meet the required fire ratings (e.g. FD30 or FD60)
- Multiple components have failed or been incorrectly installed
At FIS, we carry out detailed surveys to determine whether repair or replacement of fire doors is the most appropriate solution, ensuring cost-effective and compliant outcomes.
Our fire door replacement services
Full door set replacement
For most commercial projects, replacing the entire door set is the safest and most reliable approach.
A full fire door replacement includes:
- Door leaf
- Frame and lining
- Intumescent and smoke seals
- Hinges, closers, and ironmongery
- Glazing systems where required
Replacing the complete door set ensures all components are tested and certified to work together, which is critical for compliance with standards such as BS 476-22 and BS EN 1634-1.
Our team ensures every installation meets the requirements of Approved Document B, as well as ongoing obligations under the Regulatory Reform (Fire Safety) Order 2005 and the Fire Safety Act 2021.
Glass replacement
In some cases, only the glazing element of a fire door needs to be replaced. Fire door glass replacement must be handled carefully, as the glazing system is a critical part of the door’s fire resistance.
We provide compliant fire-rated glazing replacements, ensuring:
- Correct fire-rated glass is used
- Compatible glazing seals and systems are installed
- Certification is maintained across the full door assembly
Where glazing damage has compromised the integrity of the door, we may recommend a full fire door replacement to ensure complete compliance.
What affects the cost of fire door replacement?
The fire door replacement cost can vary depending on several factors. While every project is different, key considerations include:
- The type of fire door required (e.g. FD30, FD60, or higher ratings)
- The size and specification of the door set
- Whether glazing is included
- The condition of the existing frame and surrounding structure
- Access requirements and installation complexity
- The number of doors being replaced
Because of these variables, most projects require a site survey to provide an accurate quote. At FIS, we offer transparent pricing and clear recommendations based on your building’s specific requirements.

Fire door replacement FAQs
- How do I know if I need a fire door replacement?
- You may need a fire door replacement if your existing door is damaged, no longer closes properly, has missing seals, or doesn’t meet current UK fire safety standards. A lack of certification or evidence of performance is also a strong indicator that a replacement fire door is required. The best way to confirm this is through a professional fire door survey, where issues can be assessed against compliance requirements.
- What is included in a fire door replacement service?
- A professional fire door replacement service typically includes the removal of the existing door, installation of a fully certified replacement fire door set, and fitting of all essential components such as frames, intumescent seals, smoke seals on doors, hinges, and closers. At FIS, we ensure every element of the installation meets standards such as BS 476 and BS EN 1634, providing a fully compliant solution.
- Can fire door glass be replaced without replacing the whole door?
- In some cases, fire door glass replacement is possible if the door leaf and frame remain compliant and undamaged. However, the glazing system must be replaced using approved fire-rated glass and compatible seals to maintain performance. If the integrity of the door has been compromised, a full fire door replacement may be required to ensure compliance and safety.
- Do replacement fire doors need to be certified?
- All replacement fire doors should be third-party tested and certified to ensure they meet required fire resistance standards. Certification to standards such as BS 476-22 or BS EN 1634-1, along with installation by competent professionals, is essential for demonstrating compliance with UK fire safety legislation.
- What’s the difference between fire door replacement and repair?
- Fire door repair is suitable for minor issues such as replacing seals or adjusting hardware, while a full fire door replacement is needed when the door is significantly damaged, non-compliant, or lacks certification. A professional assessment will determine whether repair is sufficient or if a complete replacement fire door is required.
