Certified fire doorsets in Durham: what's involved
We provide certified fire doorsets in Durham (DH1 and the surrounding postcodes), from the first survey through to a documented handover.
Durham has a broad mix of buildings, including small offices, light industrial buildings and small blocks of flats, and the same fire door principles apply to all of them.
Doorsets suit refurbishment programmes in Durham, where several openings can be measured, ordered and fitted in one planned sequence. Every doorset we fit in Durham is handed over with its certificate reference and photographs of the frame fixing and gap sealing.
How is a doorset installed?
The opening is prepared to the size and tolerances in the manufacturer's instructions. The frame is fixed with the specified fixings at the specified centres, packed where needed, and checked for square, plumb and twist. The gap between frame and wall is then sealed with a material covered by the evidence, which BS 8214:2026 now describes in more detail. Finally the leaf is adjusted, the closer is set and the assembly is tested before the architraves go on.
What you get:
- Certificate references and photo record per opening
- Installation to the manufacturer's instructions
- Frame fixing and frame-to-wall gap sealing
- Pre-hung, pre-machined doorsets where available
Which fire door rules apply in Durham?
Fire doors in Durham fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in Durham above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.
Who needs certified fire doorsets in Durham?
The need for certified fire doorsets usually arises in new-build and conversion projects or blocks of flats, and sometimes schools and offices. Each has its own pressures, such as residents at home or a building that must stay open, so we plan the sequence of work in Durham to keep escape routes protected throughout.

Questions
Do you cover DH1 and nearby postcodes?
Yes. We cover Durham including DH1, and nearby towns such as Chester-le-Street and Houghton-Le-Spring. The survey and written quote are free.
How quickly can you survey in Durham?
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.
How long do doorsets take to arrive?
Lead times depend on the manufacturer, size, finish and ironmongery. Standard sizes can be quick; bespoke sizes and finishes take longer. We give you the lead time with the quote and confirm it at order.
Are doorsets more expensive than a leaf?
The product costs more, but the labour is often lower and the result is better evidenced. Where a frame would need replacing anyway, a doorset is usually the better value.
