    How the Timber Fire Escape Checker Works

    Step 01

    Check Use and Duty

    The tool first checks whether the timber stair serves a private home, flat, HMO, commercial property or formal fire escape route.

    Step 02

    Identify Timber Defects

    It then assesses rot, slippery treads, soft boards, loose supports, weak handrails, movement, poor layout and report findings.

    Step 03

    Recommend Next Step

    The final result recommends maintenance, a site survey, or likely replacement with a galvanised steel fire escape staircase.

    Useful Fire Escape & External Staircase Resources

    Compare timber condition with replacement cost, fire escape pricing, planning permission and Building Regulations before committing to repair or fabrication.

    Frequently Asked Questions

    Timber Fire Escape Replacement — Common Questions

    Can a timber fire escape staircase be repaired? +

    Sometimes, if the timber is generally sound and the problem is isolated. Minor coating failure, local staining or small non-structural repairs may be manageable. Repair is less sensible where there is rot at posts, soft treads, movement, loose guarding, poor layout or fire risk assessment comments.

    When should a timber fire escape be replaced with steel? +

    Replacement with steel is usually recommended when the timber is rotten, moving, slippery, structurally weak, repeatedly patched, or part of a tenant/HMO/commercial fire escape route. Galvanised steel is normally a better long-term option for external escape stairs.

    Why replace timber with galvanised steel? +

    Galvanised steel is stronger, non-combustible, more durable outdoors, easier to inspect and less maintenance-heavy than timber. It is usually better suited to long-term external access and fire escape use. See our fire escape stairs and outdoor steel staircase pages for more information.

    Is a slippery timber fire escape dangerous? +

    It can be. Timber treads can become slippery due to rain, algae, failed coatings and poor drainage. On a fire escape route, slip risk is more serious because occupants may need to use the staircase quickly in an emergency.

    Does a fire risk assessment mean I must replace the staircase? +

    Not always, but if the report calls for action or identifies rot, movement, loose guarding, slippery treads or inadequate escape provision, replacement should be considered seriously. A steel replacement may be easier to justify than repeated timber repairs.

    Can the new steel staircase follow the same layout? +

    Sometimes, but it should be checked. Older timber fire escapes may be too steep, too narrow, poorly guarded or missing suitable landings. A steel replacement should improve the escape route rather than simply copy a poor layout. Use our staircase compliance checker for initial Building Regulations guidance.

    What photos should I send for a steel replacement quote? +

    Send a full view of the staircase, close-ups of post bases, supports, treads, landings, rotten or soft timber, handrails, guarding, wall fixings and the fire escape route. Any fire risk assessment or survey comments are also helpful.
