Getting fire door frames right in Windsor
We provide fire door frames in Windsor (SL4 and the surrounding postcodes), from the first survey through to a documented handover.
In and around Windsor, fire door work covers everything from houses with integral garages to light industrial buildings. We plan each job around the people who use the building.
In older buildings the frame can be the weak point even where the leaf is sound, so we check it on every Windsor survey. We photograph every frame we fix in Windsor before the architraves go on, so the hidden work is on record.
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.
What you get:
- Hardwood or certified frames to suit the door
- Architraves and making good
- Fixing at specified centres with packing
- Frame-to-wall gap sealing with evidenced materials
Fire door law for Windsor properties
England's framework applies in Windsor. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in Windsor, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.
Which buildings in Windsor need fire door frames?
From converted houses to older blocks of flats, the requirement for fire door frames in Windsor comes from the fire strategy or risk assessment for the building. We work from that document, or help you interpret your inspection report, before quoting.

Questions
Do you work in Windsor?
Yes, we take on fire door frames in Windsor and the surrounding area, including Slough and Egham. Send your postcode and a few details and we'll come back with survey dates.
How quickly can you survey in Windsor?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
Why do you photograph the frame before fitting architraves?
Because the fixing and sealing are hidden once the architraves go on. Photographs give you evidence that the hidden work was done correctly.
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.
