Double fire doors for Gwynedd buildings
Our double fire doors service covers all of Gwynedd, across postcode districts including LL23, LL78 and LL57.
Every pair we fit in Gwynedd is commissioned so both leaves close in the right order and latch. Double doors on wards, school corridors and lobbies in Gwynedd take heavy use, so closing sequence and meeting-edge seals get extra attention.
Fire door work in Gwynedd spans housing providers with large estates, individual landlords, businesses and homeowners. We price every job from a survey, never from a list price alone, because the condition of the frames and the hardware makes a real difference.
Why pairs need extra care
The meeting stiles are the weak point of a pair. Gaps there must be controlled, both leaves need intumescent and smoke seals as specified, and if the meeting edges are rebated, a door coordinator is usually needed so the leaves close in the right order. If they close out of sequence, the door may not latch and will not perform as tested.
Fire door law for Gwynedd properties
Because Gwynedd is in Wales, we work to the Building Regulations as they apply in Wales and to the Welsh version of Approved Document B. The responsible person duties under the Fire Safety Order 2005 still apply to workplaces and common parts.
England's fire door checking rules for tall residential buildings do not apply in Wales, so the checking frequency for doors in Gwynedd comes from your fire risk assessment.
The steps on a Gwynedd installation
- Survey opening width, use and traffic
- Select pair configuration and hardware set
- Order certified doorset with coordinator and bolts if needed
- Install frame and hang both leaves
- Set closing sequence, seals and latching
- Test hold-open release and record evidence

Do both leaves need closers?
Usually, yes. Each leaf of a fire door pair needs to close itself. The closers are sized to each leaf's width and weight.
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.
