The short answer

Fire door remedial works are the corrective repairs carried out on a fire door after an inspection or fire risk assessment finds it will not perform for its rated period. The most common failures are excessive gaps around the leaf, missing or damaged intumescent and cold smoke seals, non fire rated or incorrectly fitted ironmongery, self closers that do not shut the door into the latch, unsealed penetrations from cables or vision panels, and damage to the leaf or frame. Most of these are fixable in situ. A minority need a full certified doorset replacement. Under Article 17 of the Regulatory Reform (Fire Safety) Order 2005, the responsible person has a legal duty to keep fire doors in efficient working order, so a survey with no remedial plan behind it is not compliance, it is just paperwork.

What are fire door remedial works?

A fire door survey tells you what is wrong. Fire door remedial works are what you do about it.

In practice, a survey produces a defect schedule: a list of doors, each with a pass, a fail, or a fail with remedial action noted. The remedial works package is the job of closing that list out, door by door, with the right components, fitted in line with the door’s supporting test evidence, and documented so you can prove it later.

That last part matters more than people expect. A fire door is a tested system, not a collection of parts. Swap in an uncertified intumescent strip or a cheaper hinge and you have quietly invalidated the evidence that the whole assembly relies on. Good remedial work is as much about the paper trail as the screwdriver.

Elmstone Fire carries out fire door surveys and fire door remedial works for commercial buildings across Kent, Medway and the South East, alongside our fire damper and passive fire protection remedials.

Why do so many commercial fire doors fail inspection?

The Fire Door Inspection Scheme has reported that roughly three quarters of the fire doors its inspectors assessed did not meet the required standards, with a significant share of those failures traced back to poor installation rather than the door itself. That figure gets quoted a lot, and the reason it keeps holding up is simple: fire doors are the one life safety system that everyone in a building physically touches, every single day.

Doors get kicked, wedged, drilled, re-keyed, painted over and fitted with a new access control reader by a contractor who has never heard of BS 8214. Over a ten year life, that adds up.

Here is what our engineers flag most often on commercial surveys, and what the fix usually looks like.

Defect found on survey	Why it fails	Typical remedial action
Gap at head and jambs outside 2mm to 4mm	Intumescent seal cannot bridge the gap when it expands	Re-hang the leaf, pack and re-fix the frame, or fit a lipping to the leaf edge
Threshold gap too large	Smoke and hot gases pass under the door long before the seal activates	Adjust or replace the leaf, or fit a certified threshold or drop seal where the evidence allows
Missing, painted over or damaged intumescent strip	The seal cannot expand and close the perimeter	Rout out and fit the correct size and type of certified seal, continuous around the leaf or frame
No cold smoke seal on a smoke control door	Door may be fire rated but not smoke rated, so escape routes fill with smoke	Fit a certified combined intumescent and brush or fin seal to the tested specification
Only two hinges, or non CE or UKCA marked hinges	Leaf distorts under heat and the door falls out of the frame	Fit three certified fire rated hinges, correctly recessed, with all screw holes filled
Self closer will not close the door onto the latch from any angle	Door sits ajar, so the rating is irrelevant	Adjust closing and latching power, service or replace the closer, correct the strike plate
Hold open devices wedged, tied or propped	Door cannot self close in a fire	Remove the wedge and fit a certified acoustic or alarm linked hold open device
Unsealed penetrations for cables, locks or conduit	Direct path for fire and smoke through the leaf	Seal with tested intumescent components, or replace the leaf if the core is compromised
Non certified vision panel or glazing bead	Glazing fails early and opens up the compartment	Reglaze with certified fire rated glass, beads and glazing system
Air transfer grille fitted into a fire door	Permanent hole in a fire barrier unless it is an intumescent grille	Replace with a certified intumescent air transfer grille or fill and make good
Damaged, warped or previously repaired leaf	Repair history is undocumented so the evidence chain is broken	Replace with a certified doorset of the correct rating
Missing or illegible signage and no door ID	You cannot evidence inspection history per door	Apply correct signage and a permanent unique door reference

Notice how many of those are cheap. The gap between a compliant door and a failed one is often a twenty minute job with the right certified component in the van.

What changed in BS 8214:2026?

This is the update most facilities managers have not caught up with yet, and it is worth two minutes of your time.

On 20 March 2026, BSI published a revised BS 8214. It replaces BS 8214:2016 and it is a bigger change than a normal refresh. According to the Architectural and Specialist Door Manufacturers Association, which helped draft it, the headline changes are:

• It is no longer timber only. The 2016 version covered timber based fire door assemblies. The 2026 edition covers fire doors of all materials, including steel, aluminium and composite, with the core principles applied across the board.
• It treats the door as a coordinated system. Leaf, frame, ironmongery, seals, glazing and installation quality are handled as one performing whole, however the door arrives on site, whether as an assembly, a doorset or a kit.
• It is less prescriptive and more evidence led. Rather than dictating fixed on site details, it focuses on what supporting evidence is needed for a given door construction, and on maintaining the specification that evidence sets.
• Smoke control guidance has been expanded. There is more on seal selection, including threshold seals for smoke control doors, reflecting a sharper focus on limiting toxic smoke spread.
• Frame to structure sealing is clarified, including the evidence expected for stone wool, mastic and foam sealants.
• It also now covers both national and European classifications, and reorders the guidance to follow the construction process from roles and responsibilities through to handover and maintenance.

The practical takeaway for a building owner: “we used a fire rated strip” is no longer a good enough answer. The question your surveyor, your insurer and your enforcing authority will ask is whether the component you fitted is covered by the supporting evidence for that specific door. If your remedial contractor cannot answer that, get a different contractor.

How often should commercial fire doors be inspected?

There is no single legal interval for most commercial buildings. There is a legal duty, and there is guidance that tells you how to discharge it sensibly.

Building type	Typical inspection frequency	What drives it
General commercial premises, offices, retail	Six monthly as best practice, minimum annually	BS 9999 guidance, backed by the Article 17 duty to maintain
High traffic doors, schools, healthcare, hospitality	Three to six monthly	Footfall, damage rate and vulnerability of occupants
Residential buildings over 11m with common parts	Quarterly for communal fire doors, annually for flat entrance doors on a best endeavours basis	Regulation 10, Fire Safety (England) Regulations 2022
Newly installed or recently remediated doors	Inspect shortly after handover, then on normal cycle	Installation defects show up early
Any door after damage, a break in, or contractor works	Immediately	Compartmentation is only as good as its last alteration

The legal backbone is Article 17 of the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to keep fire safety measures, fire doors included, in an efficient state, in efficient working order and in good repair. Your fire risk assessment then sets the frequency that suits your building. If you are unclear who carries that duty in your organisation, our guide to the responsible person’s fire safety duties is a good starting point.

For residential blocks over 11m in England, the position is firmer. Regulation 10 of the Fire Safety (England) Regulations 2022 has required quarterly checks of communal fire doors and annual best endeavours checks of flat entrance doors since January 2023.

Who is allowed to carry out fire door remedial works?

There is no single licence, which is exactly why standards vary so much. What you should be looking for instead:

• A competent, qualified inspector doing the survey. FDIS certificated inspectors or equivalent third party assessed competence is the benchmark. The person who inspects should be able to explain their findings against the door’s evidence, not just tick a form.
• Third party certificated installation. BM TRADA Q-Mark Fire Door Installation, BWF Certifire registration or an equivalent UKAS accredited scheme. This is the single most useful filter.
• Certified components with traceable documentation. Every seal, hinge, closer and glazing system should come with the paperwork that ties it back to the tested door.
• A door by door completion record. Photographs before and after, component data sheets, and a signed off defect schedule. This is what you hand to an inspecting officer or an insurer.
• A firm that will tell you when a door cannot be repaired. A contractor who says every door is fixable is either very lucky or not looking properly.

One practical warning. Fire doors are increasingly used as a wedge by companies selling long contracts on the back of alarming survey results. If a survey comes back with a very high failure rate and a very large quote from the same supplier, it is entirely reasonable to get the defect schedule independently reviewed. The same principle applies when you are choosing any commercial fire safety maintenance provider.

What do fire door remedial works cost?

Honest answer: it depends almost entirely on how many of your failures are component level and how many are doorset level.

Component level remedials, meaning seals, hinges, closers, signage, minor gap adjustment and intumescent packing, are usually a modest per door cost and can be done in bulk across a site in a single visit. This is where most of a typical defect list sits.

Doorset replacement is a different order of cost, because you are buying a certified door, frame and ironmongery package and paying for a proper installation. Where a leaf is warped, water damaged, previously butchered or has no traceable evidence at all, replacement is often the cheaper long term route anyway, because you stop paying to patch a door that will keep failing.

The cost drivers worth understanding before you get quotes:

• Number of doors and how tightly grouped they are, since mobilisation is a real share of small jobs
• Whether works must be out of hours, which is common in occupied offices, retail and hotels
• Whether the door is fire only or fire and smoke rated, as smoke control specifications are more demanding
• Whether glazing, access control or automatic operators are involved
• Whether you need a full evidence pack and O&M documentation, which most larger clients do

The sensible way to buy this is a survey first, then a priced defect schedule you can prioritise, rather than a single lump sum with no visibility of what you are paying for.

How should you prioritise a long defect list?

Almost nobody fixes every door in one go. Sequence the work by risk, not by what is cheapest:

1. Escape route and stairwell doors first. These protect the route everyone uses to leave.
2. Doors to high risk rooms. Plant rooms, kitchens, electrical intake rooms, refuse stores and boiler rooms.
3. Doors protecting sleeping risk. Hotels, care settings and any residential element.
4. Any door that will not self close or latch, wherever it is, because that is a door doing no job at all.
5. Cosmetic and administrative items last. Signage and door numbering matter for records but do not stop fire.

Then log it. A remedial programme with dates against each priority band is evidence of a reasonable approach, which is worth a great deal if you ever have to justify your decisions.

What happens if you ignore the action plan?

The risk is not usually a fine out of nowhere. It is a sequence.

An enforcing authority visits, finds unaddressed compartmentation defects, and issues an enforcement notice with a deadline. Ignore that and it escalates to prohibition of part of the building or prosecution. Alongside that, insurers increasingly ask for fire door inspection records at renewal, and a known unaddressed defect is a difficult conversation after a loss. And under the Building Safety Act regime, duty holders in higher risk buildings are expected to hold a genuine, evidenced safety case, not a folder of surveys with nothing done about them.

The common thread in enforcement cases is not that the defect existed. It is that it was known about and left.

Fire Door Safety Week, 21 to 25 September 2026

Handy timing if you need internal buy in. Fire Door Safety Week, run by the British Woodworking Federation Fire Door Alliance, lands on 21 to 25 September 2026. It is a genuinely useful hook for getting a walk round booked, briefing staff on why wedging doors open is a problem, and getting a survey approved by whoever holds the budget.

Frequently asked questions

What counts as a fire door remedial? Any corrective work that restores a fire door to its tested performance. That covers replacing intumescent and smoke seals, correcting gaps, fitting certified hinges and closers, sealing penetrations, reglazing with certified systems, and in some cases replacing the complete doorset.

Can a failed fire door be repaired, or does it have to be replaced? Most failed doors can be repaired. Replacement is normally needed when the leaf is warped, water damaged, has been cut or drilled in a way that compromises the core, or has no traceable evidence of what it is. A competent inspector should tell you which category each door falls into.

How big should the gap around a fire door be? Current guidance is a gap of roughly 2mm to 4mm at the head and jambs, so the intumescent seal can bridge it when it expands. Threshold gaps depend on the door’s test evidence and whether it is also a smoke control door. Always work to the specific door’s supporting evidence rather than a rule of thumb.

How often do commercial fire doors need to be inspected? There is no fixed legal interval for most commercial premises, but BS 9999 guidance points to six monthly inspections as best practice, with your fire risk assessment setting the final frequency. Residential buildings over 11m in England have a firmer requirement of quarterly communal door checks under Regulation 10 of the Fire Safety (England) Regulations 2022.

What is BS 8214:2026 and does it apply to my building? BS 8214:2026 is the current code of practice for fire resisting and smoke control doors, published on 20 March 2026, replacing BS 8214:2016. It now covers doors of all materials, not just timber, and treats the door as a complete system. It is guidance rather than law, but it is the benchmark a surveyor, insurer or enforcing authority will measure your doors against.

Who is legally responsible for fire doors in a commercial building? The responsible person under the Regulatory Reform (Fire Safety) Order 2005, which in practice is usually the employer, building owner, landlord or managing agent. Article 17 requires them to keep fire doors in efficient working order and good repair.

Do fire doors need to be labelled? Certified doors normally carry a plug or label identifying the manufacturer and rating. Beyond that, giving each door a unique reference makes inspection records auditable, which is what you need when you are asked to evidence compliance.

Can my usual maintenance contractor do fire door remedial works? Only if they hold third party certificated fire door installation accreditation and use certified components with traceable documentation. General joinery work on a fire door, however neat, can invalidate the door’s performance evidence.
