FD30 fire doors in Thetford: what's involved
When you book FD30 fire doors in Thetford, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
Thetford has a broad mix of buildings, including family homes after loft conversions, care homes and schools, and the same fire door principles apply to all of them.
In Thetford, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes. For a mixed portfolio in Thetford, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side.
Leaf only or a full doorset?
If the existing frame is sound, correctly sized, securely fixed and compatible with the new leaf's certification, a new FD30 leaf can be hung in it. Many frames do not pass that test: old softwood linings, frames that have been cut about for previous doors, or frames with no evidence of how they were fixed. In those cases a certified doorset (leaf, frame and ironmongery tested together) is the cleaner answer and usually the quicker one on site.
We tell you which route each opening needs on the survey, door by door, and why.
As standard, the work covers:
- Intumescent strips and smoke seals to the certification
- Survey of the opening, frame and existing ironmongery
- Frame-to-wall gap sealed with an evidenced material
- Overhead closer set to close and latch
The regulations behind fire doors in Thetford
In Thetford, 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 Thetford 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.

Common questions
Is Thetford within your coverage area?
It is. We cover Thetford in Norfolk and neighbouring towns such as Bury St Edmunds. There is no charge for the survey.
What happens on a survey in Thetford?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
Do FD30 doors need a closer?
Most do. Doors on escape routes, flat entrance doors and doors in the common parts of buildings need a self-closing device that shuts and latches the door. Some doors inside houses and locked riser doors are exceptions, depending on the fire strategy.
What is the difference between FD30 and FD30S?
FD30S has been tested for smoke control as well as fire. It adds a smoke seal, usually a brush or blade, and needs a tight threshold gap. Flat entrance doors and doors onto protected escape routes are commonly specified as FD30S.
