Fire door frames in Harpenden, done to the evidence
Looking for fire door frames in Harpenden? We supply and fit certified fire doors and components across Harpenden and the wider Hertfordshire area, working from a free survey and a fixed written quote.
Fire doors in Harpenden protect escape routes in family homes after loft conversions, houses with integral garages and care homes alike. We adapt the programme to the building and its occupants, never the standard of the installation.
We photograph every frame we fix in Harpenden before the architraves go on, so the hidden work is on record. Frame-to-wall gaps on Harpenden jobs are sealed with materials supported by the test evidence, as BS 8214:2026 sets out.
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.
As standard, the work covers:
- Assessment of frame condition and compatibility
- Frame-to-wall gap sealing with evidenced materials
- Architraves and making good
- Photographs of fixing and sealing before covering
The regulations behind fire doors in Harpenden
In Harpenden, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Harpenden building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.
Who needs fire door frames in Harpenden?

In Harpenden, as anywhere, the duty holder varies: a responsible person for a workplace, a landlord or managing agent for a block or HMO, or a homeowner after building work. We adjust access, timing and paperwork to suit whoever commissions the work.

Questions from Harpenden
Do you work in Harpenden?
Yes, we take on fire door frames in Harpenden and the surrounding area, including St Albans and Luton. Send your postcode and a few details and we'll come back with survey dates.
Can you work from an existing inspection report for my Harpenden building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
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.
Can I use expanding foam around a fire door frame?
Only a fire-rated foam with evidence for that use and gap size. Ordinary expanding foam is not suitable.
