Getting steel fire doors right in Cornwall
For steel fire doors anywhere in Cornwall, one team handles the survey, supply, installation and handover, covering Redruth, Falmouth, St Austell and the rest of the county.
For steel fire doors in Cornwall we order factory-prepared doorsets so the hardware matches the test evidence exactly. We anchor and seal steel frames in Cornwall buildings to the manufacturer's instructions and photograph the work before it is covered.
Wherever your building is in Cornwall, the fire safety duties come from national rules, and our installation standard is the same.
How installation differs from timber
Steel frames are fixed with the anchors and fixing centres the manufacturer specifies, and frames are often grouted or packed according to the instructions. Steel doors usually arrive with hinges and hardware preparations made in the factory, so the hardware set must be ordered correctly at the outset. BS 8214:2026 now covers steel, metal and composite doors as well as timber, including how to seal them to the surrounding structure.
The regulations behind fire doors in Cornwall
The rules that apply to fire doors in Cornwall 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.
Where a Cornwall 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
Do you provide steel fire doors across Cornwall?
Yes. We cover all of Cornwall, including Redruth and Falmouth. Surveys and written quotes are free.
Do steel fire doors need intumescent seals?
Some steel doorsets use intumescent seals and some do not, depending on how they were tested. The certification sets out exactly what is required.
Are steel fire doors better than timber?
Not better, just suited to different places. Steel doors are tougher and resist damp and impact, so they suit plant rooms and industrial areas. Timber doors are more common in residential and office interiors.
