Double fire doors in Derry: what's involved
When you book double fire doors in Derry, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
Derry has a broad mix of buildings, including low-rise blocks of flats, industrial estates and houses with integral garages, and the same fire door principles apply to all of them.
Every pair we fit in Derry is commissioned so both leaves close in the right order and latch. Leaf-and-a-half doors are a practical option for Derry care homes and schools that need occasional wide access.
Leaf-and-a-half for wider routes
Leaf-and-a-half doors give a usable everyday opening through the main leaf, with the smaller leaf opened for beds, trolleys or deliveries. They are common in care homes, hospitals and schools. The smaller leaf may be held with flush bolts; any bolts and their positions must be covered by the evidence.
On a typical job that means:
- Equal pair or leaf-and-a-half doorsets
- Closers matched to each leaf
- Meeting-stile intumescent and smoke seals
- Door coordinators where meeting edges are rebated

Common questions
Do you cover BT48 and nearby postcodes?
Yes. We cover Derry including BT48, and nearby towns such as Coleraine and Omagh. The survey and written quote are free.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
Why does the gap between the two leaves matter?
The meeting edges are where flame and smoke can pass most easily. The gap and the seals there must match the certification for the pair to perform as tested.
Can double fire doors be held open?
Yes, with hold-open devices that release on the fire alarm, or with free-swing closers. Wedges and hooks are not acceptable.
