Getting certified fire doorsets right in Lisburn
For property owners, landlords and managing agents in Lisburn, we offer certified fire doorsets with one team for the survey, the product and the installation.
Buildings in and around Lisburn range from low-rise blocks of flats to high-street shops and industrial estates. 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 Lisburn, with less cutting and fewer return visits. Every doorset we fit in Lisburn 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:
- Certificate references and photo record per opening
- Installation to the manufacturer's instructions
- Doorset selection to rating, size and use
- Closer set-up and close-and-latch testing
Fire door law for Lisburn properties
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.

Questions from Lisburn
Do you work in Lisburn?
Yes, we take on certified fire doorsets 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.
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.
Can a doorset be fitted into an existing opening?
Usually, yes. Doorsets are made to fit the structural opening once the old frame is removed. We measure the opening on the survey so the doorset is made to the right size and the gaps to the wall stay within what the evidence allows.
How long do doorsets take to arrive?
Lead times depend on the manufacturer, size, finish and ironmongery. Standard sizes can be quick; bespoke sizes and finishes take longer. We give you the lead time with the quote and confirm it at order.
