Managing agents, landlords, schools, care providers, businesses and homeowners in County Durham 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.
The regulations behind fire doors in County Durham
In County Durham, 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 County Durham 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.

Certified fire doorsets questions
Do you provide certified fire doorsets across County Durham?
Yes. We cover all of County Durham, including Darlington and Hartlepool. Surveys and written quotes are free.
Do doorsets come painted?
They can be supplied primed, factory painted, veneered, laminated or with a composite skin, depending on the product. Factory finishes avoid painting over seals and labels on site.
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.
