Getting certified fire doorsets right in Castlereagh
From the BT6 postcode district outwards, we take on certified fire doorsets across Castlereagh for homes, blocks and workplaces.
Buildings in and around Castlereagh range from houses with integral garages to HMOs and family homes after loft conversions. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Pre-hung doorsets keep disruption down in occupied buildings in Castlereagh, with less cutting and fewer return visits. Every doorset we fit in Castlereagh is handed over with its certificate reference and photographs of the frame fixing and gap sealing.
How is a doorset installed?
The opening is prepared to the size and tolerances in the manufacturer's instructions. The frame is fixed with the specified fixings at the specified centres, packed where needed, and checked for square, plumb and twist. The gap between frame and wall is then sealed with a material covered by the evidence, which BS 8214:2026 now describes in more detail. Finally the leaf is adjusted, the closer is set and the assembly is tested before the architraves go on.
On a typical job that means:
- Installation to the manufacturer's instructions
- Doorset selection to rating, size and use
- Frame fixing and frame-to-wall gap sealing
- Pre-hung, pre-machined doorsets where available
