Fire door frames in Harrow, done to the evidence
When you book fire door frames in Harrow, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
Buildings in and around Harrow range from schools to student accommodation and restaurants. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Frame-to-wall gaps on Harrow 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 Harrow 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.
On a typical job that means:
- Frame-to-wall gap sealing with evidenced materials
- Architraves and making good
- Hardwood or certified frames to suit the door
- Photographs of fixing and sealing before covering
Fire door law for Harrow properties
The rules that apply to fire doors in Harrow are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts. In London, the London Fire Brigade is the enforcing authority for fire safety law.
Where a Harrow block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

Questions from Harrow

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.
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.
