A correctly installed and maintained fire door helps slow the spread of fire and smoke, protects escape routes and supports the wider fire safety strategy for a building.

    FAQs

    Frequently asked questions

    Yes. Inspection frequency should reflect the fire risk assessment and the door's use. In blocks of flats where the top storey is above 11 metres, communal fire doors must be checked at least every three months and best endeavours used to check flat entrance doors at least every 12 months.

    Cost varies with door type, quantity and site conditions. We provide clear, itemised pricing following a site survey.

    Check that the door and frame are undamaged, the door closes fully into its frame, hinges and other hardware are secure, strips and smoke seals (if present) are intact, and the gap between the door and frame does not exceed 4 mm. The threshold gap should be as small as practicable. A simple visual check does not replace a specialist assessment.

    Yes, but decoration must follow the door manufacturer's instructions and must not damage or cover seals, certification labels or other safety-critical components.

    Flat entrance fire doors and fire doors in common parts generally need effective self-closing devices. Doors to plant rooms, service cupboards and risers may instead be kept locked shut where appropriate. The building's fire risk assessment should be followed.

    Modern fire doors commonly use intumescent strips as part of their tested specification. However, current government guidance says their absence on an older door does not automatically mean the door is unfit for purpose. Suitability must be considered through the fire risk assessment and available evidence.

    An FD30 door provides 30 minutes of fire resistance, while an FD60 provides 60 minutes — used in higher-risk areas and critical compartment boundaries.

    In blocks of flats where the top storey is above 11 metres, communal fire doors must be checked at least every three months and best endeavours used to check flat entrance doors at least every 12 months. Other inspection frequencies should follow the fire risk assessment, building use and level of wear.

    Typically in stairwells, corridors, compartment lines, plant rooms, escape routes and other high-risk zones as defined by your fire risk assessment.

    Fire doors should be installed by certified, competent professionals to ensure and evidence compliance — which is exactly what our accredited team provides.
