Questions from Belfast clients

Does regulation 10 apply in Belfast?

No. Belfast is in Northern Ireland, where the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 apply.

Why do gaps open up over time?

Hinges wear and drop, frames shrink or move, leaves warp, and doors are sometimes planed after flooring changes. Each needs a different repair.

How big can the gap under a fire door be?

It depends on the door's evidence. Doors without smoke control often allow a larger threshold gap, sometimes up to around 8 to 10 mm, while smoke control doors usually need 3 mm or less or a tested drop seal.

Do you work in occupied buildings in Belfast?

Yes. Inspections and repairs in Belfast can be carried out in occupied flats, schools, care homes and workplaces, with doors kept closable at all times.
