Brief:

Following a fire door inspection survey conducted by an LPCB-accredited company on behalf of The Crown Estate, Active was appointed to carry out the necessary fire door remedial and replacement works. The scope included the complete replacement of multiple fire door and frame sets, all delivered in accordance with the BM TRADA Q-Mark certification scheme, ensuring full compliance with current fire safety regulations and performance standards. Additionally, various remedial works were undertaken on multiple doors, including:
  • Door and frame adjustments to achieve compliant gap tolerances.
  • Installation of new intumescent strips.
  • Installation of dropdown smoke seals.
  • Replacement of ironmongery components such as hinges and door closers.
  • Repairs to damaged doors and frames
  • Repairs to walls around the door sets
  • Encapsulation of existing asbestos
This comprehensive approach ensured that all fire doors—whether newly installed or remediated—fully met the required safety, performance, and compliance standards.

Delivery:

Carrying out works in open and operational buildings presents inevitable challenges—particularly when it comes to minimising disruption to staff and tenants. Drawing on our extensive experience delivering projects in live environments, we prioritise building strong working relationships with our clients. This collaborative approach enables us to schedule works at the most appropriate times, whether that involves working outside of normal hours or during quieter periods of the day. Recognising the impact of noise in office environments, we make every effort to carry out disruptive activities within pre-agreed time windows, ensuring minimal disturbance to building occupants. What made this project particularly unique compared to most fire door replacement schemes was the client’s requirement to match the new, compliant fire door sets to the building’s original period-style doors. These bespoke door types are not commonly available through standard manufacturers. However, by working in close collaboration with our fire door manufacturer and referencing relevant test evidence, we were able to make controlled modifications in our workshop to replicate the original design features, while ensuring the fire integrity and certification remained fully intact.

Results:

The final outcome was a great success for both our client and the landlord. Replacing feature doors in a historic building often raises concerns about achieving the correct finish, but this project was executed seamlessly, meeting both aesthetic expectations and compliance requirements. The customer was able to select a new finish that aligned perfectly with the planned re-decoration of the communal areas. This project is just one of many similar schemes that Active has successfully completed within this client’s portfolio, reflecting their continued confidence in the quality of our workmanship and the final product we consistently deliver.
