Steel fire doors for Lisburn buildings
If you need steel fire doors in Lisburn, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
Buildings in and around Lisburn range from houses with integral garages to low-rise blocks of flats and care homes. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Plant rooms, bin stores and warehouses in and around Lisburn often call for steel doorsets that can take knocks and damp. We anchor and seal steel frames in Lisburn buildings to the manufacturer's instructions and photograph the work before it is covered.
How installation differs from timber
Steel frames are fixed with the anchors and fixing centres the manufacturer specifies, and frames are often grouted or packed according to the instructions. Steel doors usually arrive with hinges and hardware preparations made in the factory, so the hardware set must be ordered correctly at the outset. BS 8214:2026 now covers steel, metal and composite doors as well as timber, including how to seal them to the surrounding structure.
On a typical job that means:
- Single and double steel doorsets
- Ratings to suit the wall, including 60 minutes
- Frame anchoring and gap sealing to instructions
- Powder-coated finishes

Common questions
Do you cover BT27 and nearby postcodes?
Yes. We cover Lisburn including BT27, and nearby towns such as Belfast and Castlereagh. 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.
Do steel fire doors need intumescent seals?
Some steel doorsets use intumescent seals and some do not, depending on how they were tested. The certification sets out exactly what is required.
Can steel fire doors be painted?
They are usually supplied powder coated. Repainting on site is possible but must avoid covering seals and labels, and should follow the manufacturer's guidance.
