For property owners, landlords and managing agents in Chalfont St Peter, we offer loft conversion fire doors with one team for the survey, the product and the installation.
In and around Chalfont St Peter, fire door work covers everything from small blocks of flats to light industrial buildings. We plan each job around the people who use the building.

FD20 or FD30?
In England, the guidance generally asks for FD20 (E20) doors in this situation, and self-closers are not usually required within a house. Scotland is different: the domestic Technical Handbook expects doors onto the protected stair enclosure to be self-closing fire doors, so closers are part of the job there. Many homeowners choose FD30 doors anyway, because they are widely available and the price difference is small. Either way, the door must be fitted properly: correct gaps, fire-tested hinges and an intumescent strip where the product requires one.
What you get:
- Product details for building control
- Work coordinated with your builder
- Fire-tested hinges and intumescent strips as required
- Check of which openings need fire doors

Usually the doors from habitable rooms onto the stair do, on every floor. Bathrooms are often excluded. Building control decides for your house.
Can you match my existing doors?
Certified fire doors come in many styles, including panelled and cottage designs, so a close match is usually possible.
