Loft conversion fire doors questions
Do you provide loft conversion fire doors across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
Do loft conversion fire doors need closers?
Not usually within a single-family house in England. In Scotland, doors onto the protected stair enclosure are expected to be self-closing. Wales and Northern Ireland have their own guidance, and your building control body may ask for something different in particular layouts.
Do all my doors need to be fire doors after a loft conversion?
Usually the doors from habitable rooms onto the stair do, on every floor. Bathrooms are often excluded. Building control decides for your house.
