Fire door frames in Derry, done to the evidence
When you book fire door frames in Derry, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
Fire doors in Derry protect escape routes in care homes, houses with integral garages and HMOs alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Frame-to-wall gaps on Derry jobs are sealed with materials supported by the test evidence, as BS 8214:2026 sets out. In older buildings the frame can be the weak point even where the leaf is sound, so we check it on every Derry survey.
BS 8214:2026 and the frame-to-wall gap
The 2026 revision of BS 8214 strengthened its guidance on sealing the gap between the frame and the surrounding structure, listing material types such as stone wool, mastic and fire-rated foam, and putting the emphasis on using what the evidence supports. We fill and seal that gap with materials covered by the doorset's or sealant's test evidence and photograph it before the architraves go back on.
Each installation includes:
- Architraves and making good
- Hardwood or certified frames to suit the door
- Fixing at specified centres with packing
- Photographs of fixing and sealing before covering

Questions
Do you cover BT48 and nearby postcodes?
Yes. We cover Derry including BT48, and nearby towns such as Coleraine and Omagh. The survey and written quote are free.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
Can a new frame be fitted to my existing door?
Sometimes, if the frame is compatible with the door's certification. Often it is simpler and better evidenced to replace the whole doorset.
What is the frame-to-wall gap?
It is the space between the door frame and the surrounding wall, normally hidden by the architrave. If it is not filled with a suitable fire-resisting material, fire and smoke can pass around the door.
