Getting loft conversion fire doors right in Harpenden
Our loft conversion fire doors service covers Harpenden and the wider Hertfordshire area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
Fire doors in Harpenden protect escape routes in family homes after loft conversions, houses with integral garages and schools alike. We adapt the programme to the building and its occupants, never the standard of the installation.
A loft conversion in Harpenden that adds a new storey often brings a building control requirement for fire doors on rooms off the stair. For homes in Harpenden, we match fire doors to your existing style wherever certified options allow.
Why loft conversions trigger fire doors
A two-storey house usually lets people escape from upstairs windows. Once a loft room is added, the top floor is too high for that, so the stair becomes the escape route and has to be protected from the ground floor up. That is why building control often asks for fire doors on rooms off the stair, including existing ground and first-floor rooms, not just the new loft room.
What you get:
- Check of which openings need fire doors
- Fire-tested hinges and intumescent strips as required
- FD20 or FD30 doors in your chosen style
- Work coordinated with your builder

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.
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.
