Common questions in Coleraine

Do you cover the area around Coleraine?

Yes. As well as Coleraine itself we cover nearby towns including Ballymena, Derry and Londonderry County Borough.

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.

Which fire safety law applies in Coleraine?

The Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 require fire safety measures, including fire doors, to be maintained.
