What loft conversion fire doors in Windsor should include
We provide loft conversion fire doors in Windsor (SL4 and the surrounding postcodes), from the first survey through to a documented handover.
Windsor has a broad mix of buildings, including small blocks of flats, small offices and family homes after loft conversions, and the same fire door principles apply to all of them.
A loft conversion in Windsor that adds a new storey often brings a building control requirement for fire doors on rooms off the stair. We can fit loft conversion fire doors in Windsor as your builder's subcontractor or directly for you.
Working with your builder and building control
We can work as a subcontractor to your loft conversion builder or directly for you. We fit doors to match your existing style where certified options exist, and leave product details for building control. Wales, Scotland and Northern Ireland have their own guidance on escape from upper floors; we check which applies to your home.
Each installation includes:
- Frame repairs or new linings where needed
- Fire-tested hinges and intumescent strips as required
- FD20 or FD30 doors in your chosen style
- Check of which openings need fire doors
Fire door law for Windsor properties
England's framework applies in Windsor. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in Windsor, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.
Which buildings in Windsor need loft conversion fire doors?
The need for loft conversion fire doors usually arises in detached family homes or bungalows gaining an upper floor, and sometimes terraced houses. In Windsor we can work for you directly or alongside your builder, and single doors are as welcome as whole-house jobs.

Common questions
Is Windsor within your coverage area?
It is. We cover Windsor in Berkshire and neighbouring towns such as Slough. There is no charge for the survey.
Can you work from an existing inspection report for my Windsor building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
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.
Can I just add intumescent strips to my existing doors?
Generally no. A standard internal door is not a fire door, and strips alone will not make it one. Existing doors need to be replaced with certified fire doors.
