Certified fire doorsets: our service in Kent
For certified fire doorsets anywhere in Kent, one team handles the survey, supply, installation and handover, covering Maidstone, Gillingham, Chatham and the rest of the county.
Pre-hung doorsets keep disruption down in occupied buildings in Kent, with less cutting and fewer return visits. Doorsets suit refurbishment programmes in Kent, where several openings can be measured, ordered and fitted in one planned sequence.
Managing agents, landlords, schools, care providers, businesses and homeowners in Kent can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
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 the rules say for Kent
Fire doors in Kent 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 Kent 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.

Questions
Do you provide certified fire doorsets across Kent?
Yes. We cover all of Kent, including Maidstone and Gillingham. Surveys and written quotes are free.
Can a doorset be fitted into an existing opening?
Usually, yes. Doorsets are made to fit the structural opening once the old frame is removed. We measure the opening on the survey so the doorset is made to the right size and the gaps to the wall stay within what the evidence allows.
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.
