Fire door frames in City of Westminster: what's involved
Our fire door frames service in City of Westminster is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Fire doors in City of Westminster protect escape routes in purpose-built blocks of flats, schools and hotels alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Frame-to-wall gaps on City of Westminster 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 City of Westminster survey.
Why frames fail inspections
Many fire door problems start with the frame: softwood linings too thin for the door, frames cut back to fit a previous door, frames loose in the wall, or gaps behind the architrave stuffed with ordinary foam or left open. A perfect leaf hung in a frame like that cannot be relied on.
What you get:
- Hardwood or certified frames to suit the door
- Photographs of fixing and sealing before covering
- Assessment of frame condition and compatibility
- Fixing at specified centres with packing
What the rules say for City of Westminster
England's framework applies in City of Westminster. 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. In London, the London Fire Brigade is the enforcing authority for fire safety law.
For blocks over 11 metres in City of Westminster, 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.

The need for fire door frames usually arises in converted houses or schools, and sometimes older blocks of flats.

Common questions
Do you cover SW1E and nearby postcodes?
Yes. We cover City of Westminster including SW1E, and nearby towns such as Pimlico and London. 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.
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.
