    FAQs

    Frequently asked questions

    Yes. Fire doors are safety-critical and should be inspected regularly — typically every six or twelve months depending on building use and footfall.

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

    Look for a valid certification label, correct gaps (typically 2–4 mm), a working self-closer, intact intumescent and smoke seals, and certified hardware. If in doubt, book a compliance survey.

    Yes, provided approved products are used and applied correctly so as not to compromise the door's fire performance.

    Most fire doors require a working self-closer to ensure they close fully and hold back fire and smoke.

    Yes. Intumescent strips expand when heated to seal the gaps around the door, preventing the spread of fire and smoke.

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

    Communal and high-traffic fire doors should be inspected every six months; lower-use doors at least every twelve months.

    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.
