FD30 fire doors in Lisburn, done to the evidence
Our FD30 fire doors service covers Lisburn and the wider County Antrim area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
Lisburn has a broad mix of buildings, including industrial estates, schools and low-rise blocks of flats, and the same fire door principles apply to all of them.
In Lisburn, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes. Each FD30 leaf we supply for Lisburn is sized for the opening, rather than trimmed beyond what its certification allows.
What does a correct FD30 installation include?
A typical timber FD30 leaf is around 44mm thick and hangs on at least three fire-tested hinges. The gaps between leaf and frame are set to the manufacturer's data, usually around 3mm. Intumescent strips, and smoke seals where needed, go in the frame or leaf edge as specified. The closer must pull the door shut and latch it from any angle. Every hole cut for a lock, latch or hinge is lined with intumescent material where the certification calls for it.
Then comes the part that is often skipped: sealing the gap between the frame and the wall with a tested material, as BS 8214:2026 now sets out in more detail.
On a typical job that means:
- Fire-tested hinges, latch or lock and intumescent pads
- Intumescent strips and smoke seals to the certification
- Photo record, product data and certificate references at handover
- Frame-to-wall gap sealed with an evidenced material
The regulations behind fire doors in Lisburn
Lisburn is in Northern Ireland, where fire doors are covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E on fire safety. Duties in non-domestic premises come from the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010.
The English regulation 10 checking regime does not apply here, so the fire risk assessment sets how often doors in Lisburn are checked. We hand over evidence that supports it.

Common questions
Do you work in Lisburn?
Yes, we take on FD30 fire doors in Lisburn and the surrounding area, including Belfast and Castlereagh. Send your postcode and a few details and we'll come back with survey dates.
What happens on a survey in Lisburn?
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.
Can a new FD30 door go into my old frame?
Sometimes. The frame has to be sound, square, securely fixed and compatible with the new leaf's certification. Many older frames are not, especially softwood linings or frames altered for previous doors. We check each frame on the survey and recommend a doorset only where the frame cannot be relied on.
