Certified fire doorsets in Lincolnshire: what's involved
Whether your building is in Lincoln, Grimsby or a smaller place in Lincolnshire, we can provide certified fire doorsets with the same evidence-led approach.
Doorsets suit refurbishment programmes in Lincolnshire, where several openings can be measured, ordered and fitted in one planned sequence. Every doorset we fit in Lincolnshire is handed over with its certificate reference and photographs of the frame fixing and gap sealing.
Managing agents, landlords, schools, care providers, businesses and homeowners in Lincolnshire can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
Why choose a doorset over a door leaf?
A fire door's rating belongs to the assembly that was tested, not to the leaf on its own. When a certified leaf is hung in an old frame with mismatched hinges and seals, nobody can say with confidence how it will perform. A doorset arrives with the frame, gaps and ironmongery already matched, so the installer's job is to fix it correctly into the opening and seal it to the structure.
Doorsets also cut time on site, which matters in occupied buildings: less cutting, less dust and fewer return visits.
Which fire door rules apply in Lincolnshire?
The rules that apply to fire doors in Lincolnshire 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 Lincolnshire 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.
The steps on a Lincolnshire installation
- Survey and measure every structural opening
- Specify doorsets by rating, size, hand, finish and hardware
- Prepare openings and remove existing doors and linings
- Fix and seal the frames to the structure
- Hang, adjust and test each leaf and closer
- Fit architraves, make good and hand over evidence
What does certified fire doorsets cost in Lincolnshire?
As a guide, budget £650–£1,300 for an FD30 doorset and £850–£1,800 for FD60, supplied and fitted, ex VAT for certified fire doorsets. The figure for your Lincolnshire building depends on the number of doors, the rating, the condition of the frames, finishes, hardware and access. We confirm a fixed price after the free survey.
Common questions
Do you provide certified fire doorsets across Lincolnshire?
Yes. We cover all of Lincolnshire, including Lincoln and Grimsby. 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.
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.
