What FD30 fire doors in Windsor should include
From the SL4 postcode district outwards, we take on FD30 fire doors across Windsor for homes, blocks and workplaces.
Windsor has a broad mix of buildings, including family homes after loft conversions, care homes and small blocks of flats, and the same fire door principles apply to all of them.
In Windsor, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes. For a mixed portfolio in Windsor, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side.
What does a correct FD30 installation include?
A typical timber FD30 leaf is around 44mm thick and hangs on at least three fire-tested hinges. The gaps between leaf and frame are set to the manufacturer's data, usually around 3mm. Intumescent strips, and smoke seals where needed, go in the frame or leaf edge as specified. The closer must pull the door shut and latch it from any angle. Every hole cut for a lock, latch or hinge is lined with intumescent material where the certification calls for it.
Then comes the part that is often skipped: sealing the gap between the frame and the wall with a tested material, as BS 8214:2026 now sets out in more detail.
On a typical job that means:
- Frame-to-wall gap sealed with an evidenced material
- Intumescent strips and smoke seals to the certification
- Overhead closer set to close and latch
- Certified FD30 or FD30S leaf, or full doorset
What the rules say for Windsor
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.

Common questions
Do you cover SL4 and nearby postcodes?
Yes. We cover Windsor including SL4, and nearby towns such as Slough and Egham. The survey and written quote are free.
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.
Can a new FD30 door go into my old frame?
Sometimes. The frame has to be sound, square, securely fixed and compatible with the new leaf's certification. Many older frames are not, especially softwood linings or frames altered for previous doors. We check each frame on the survey and recommend a doorset only where the frame cannot be relied on.
How long does it take to fit an FD30 door?
A leaf into a sound frame is often a few hours. A full doorset including frame removal, fixing, sealing and making good is usually half a day to a day per opening, depending on access and the wall construction.
