Fire Door Maintenance & Remediation

What is fire door maintenance and remediation?

Fire door maintenance is the planned, ongoing work that keeps a certificated fire door performing exactly as it was tested — adjusting the self-closer, replacing worn or damaged seals, renewing loose ironmongery and correcting the gaps around the leaf. Remediation is the corrective work that puts right defects a fire door inspection or survey has identified, either door by door or as a programme across a whole building. Both share one non-negotiable rule: every repair must keep the door within its tested and certified specification.

The distinction matters for planning: maintenance is cyclical work on a set cycle, while remediation is finite, defect-led work that clears a survey backlog and returns a stock of doors to a compliant baseline before a maintenance regime takes over. Neither is cosmetic — a repair that departs from the certified design can quietly undo the very performance it was meant to preserve.

What is the legal duty to maintain fire doors?

Once a building is occupied, Article 17 of the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to ensure that fire safety measures — fire doors among them — are 'subject to a suitable system of maintenance and are maintained in an efficient state, in efficient working order and in good repair'. Maintenance is therefore not optional housekeeping; it is a standing legal duty that runs for the whole life of the building and sits with the responsible person, not the contractor.

Statutory checking intervals in England

In England, the Fire Safety (England) Regulations 2022 add specific checking duties in buildings containing two or more sets of domestic premises that are above 11 metres in height. Under regulation 10, the responsible person must undertake checks of any fire doors in communal areas at least every 3 months, and use best endeavours to check flat entrance doors at least every 12 months. These are minimum residential checking intervals for tall blocks in England only — they do not set the maintenance frequency for non-domestic premises or for buildings elsewhere in the UK, where the fire risk assessment and standards such as BS 9999 govern.

Repairs must be carried out by a competent person

Government guidance under the 2022 Regulations is explicit that where a check identifies the need for repair or replacement of a fire door, 'this work must be undertaken by a competent contractor as soon as reasonably practicable', and a replacement door should be installed by a competent person. There is no statutory licence to work on fire doors in the UK, but competence — the right skills, knowledge, experience and behaviours — is a legal requirement, reinforced by regulation 11F of the Building Regulations 2010 for building work. Maintenance and remediation should therefore be evidenced, traceable and carried out by people who understand what keeps a door within its certification.

What does fire door maintenance and remediation involve?

Most fire door faults fall into a handful of recurring categories, and the correct response is defined by the doorset's certified design and the manufacturer's instructions rather than by improvisation. The table below sets out common faults, the maintenance or remediation action, and — the question that matters most — whether that action keeps the door within its certification.

Closing and latching adjustment

A fire door only works if it is shut. The most common maintenance task is restoring reliable self-closing and latching: adjusting closer speed and latching action, freeing binding hinges, and confirming the leaf engages the frame from any angle. Where a closer has failed, it is replaced with a device to BS EN 1154 that sits within the doorset's certified scope — not simply the nearest closer to hand.

Seal replacement matched to the certified spec

Intumescent and cold smoke seals degrade, get painted over or are torn out over time. They are replaced like-for-like with the seal specified in the certified design — the same type, dimensions and configuration — because a substituted seal can change how the door behaves in a fire. Fitting a smoke seal where the certified design calls for a combined intumescent and smoke seal, or vice versa, is not a valid repair.

Hinge, ironmongery and gap correction

Loose or non-fire-rated hinges are renewed with graded hinges to BS EN 1935 within the certified scope, and fixing holes are made good so the leaf still hangs true. Gap correction — bringing head and jamb gaps back within tolerance — may involve frame adjustment or certified lipping, but only up to the point where the door still matches its tested configuration. Beyond that, the door is a replacement candidate, not a repair one.

When must a fire door be replaced instead of repaired?

A fire door only performs as tested if every element stays within the certified design, so the repair-versus-replace decision turns on whether the fix can be made using the manufacturer's approved methods and components. Minor, well-defined damage — a worn closer, a missing seal, a loose hinge — is squarely maintenance. Damage that goes beyond the certified repair scope — a split or through-holed leaf, an aperture cut outside the tested limits, or a door with no traceable certification at all — cannot legitimately be patched. It should be replaced with a certified fire doorset.

The honesty point matters: a non-certified 'fix' does not just look untidy, it voids the tested performance. Bulking out an oversized gap with an unproven material, fitting a random closer, cutting a letterplate into an FD30 leaf, or bonding modern seals onto a door that was never fire-tested all take the door outside its evidence — so it can no longer be relied on to meet the rating the fire risk assessment depends on.

Any replacement must match the required rating on its own certified evidence, not on appearance. An FD30 doorset demonstrates at least 30 minutes' integrity — broadly E30 under BS EN 13501-2, not EI30 — so replacing 'like for like' means matching the tested classification the building needs, confirmed by the fire strategy or risk assessment. Fitting a complete factory-assembled doorset removes the component-compatibility risk that comes with patching a hung leaf and gives the responsible person a single traceable certificate for the opening.

How do planned maintenance contracts and remediation programmes work?

Planned maintenance contracts

A planned maintenance contract sets a fixed cycle of visits aligned to the checking intervals that apply to your building, with each door serviced, adjusted and — where needed — repaired within its certified specification. The frequency is driven by the fire risk assessment and, where relevant, the statutory intervals below. Every visit produces a per-door record with photographic evidence, so the responsible person can demonstrate the 'suitable system of maintenance' that Article 17 requires.

Remediation programmes following a survey

A remediation programme starts from a survey. Every fire door is assessed against its certification and the current guidance, defects are logged door by door, and the findings are turned into a prioritised schedule — worst-first, weighted by risk and location. Work is then delivered in a controlled sequence: seals, closers, ironmongery and gaps corrected within the certified design where the door can be brought back to standard, and full certified doorset replacement scheduled where it cannot.

The output is an auditable trail: before-and-after photographs, the action taken on each door, the components fitted and the date. That record supports the golden thread on higher-risk buildings and the fire safety information the responsible person must hold, and it gives a fire risk assessor or enforcing authority a clear picture of what was found and what was put right.

How will our fire door maintenance and remediation service work?

When we open in 2026, our maintenance and remediation service will be built around one principle: keep every door within its certified specification, or replace it with one that carries its own certification. We will not offer cosmetic 'fixes' that leave a door looking compliant while its tested performance has been quietly lost. What the service will include:

• Planned maintenance visits on a cycle matched to your building's fire risk assessment and any applicable statutory checking intervals.
• Repairs kept within the certified design — closers to BS EN 1154, hinges to BS EN 1935, and seals replaced like-for-like with the certified specification.
• Survey-led remediation programmes with a prioritised, worst-first schedule and clear repair-versus-replace decisions.
• Certified doorset replacement where damage or a notional door falls outside any repairable scope.
• Per-door photographic reporting that feeds the responsible person's maintenance records and, where relevant, the golden thread.
• Competence you can verify — any third-party accreditation will be published here the day it is granted, never claimed in advance.

Because we are pre-launch, we cannot quote a job today and we do not publish our own prices. Where you need indicative figures, the fire door cost guide sets out typical UK market ranges for repair and replacement so you can budget realistically. When we open, you will be able to get in touch to arrange a survey or discuss a planned maintenance contract.
