By Sebastian Grabowski, DC Fire & Security. Fire door repairs by our own carpenters, priced from your report or photos. Updated October 2026.
Usually, yes. If the leaf and frame are sound, most failed fire doors are a repair job: new intumescent and smoke seals, a closer adjusted or replaced, gaps brought back to around 3mm, hinges and screws put right. Our own carpenters do the work to BS 8214, and every door gets before and after photos and a completion report. If a door can't be saved, we say so and price a replacement instead.
Some doors are past saving: a hollow or delaminated leaf, a door with no evidence it was ever a fire door, or a frame that has been cut about too much. Those get a replacement price instead, and we tell you why.
All prices are plus VAT and fixed for a compliant, certified result. Parts we don't use come off, everything else stays the same whatever we find on the day.

If you have more than a handful of doors and no recent report, an inspection first usually saves money, because we only fix what has actually failed. Fire door inspections are £25 a door, minimum £250 for up to 10 doors.
In blocks of flats over 11 metres, communal fire doors must be checked every three months and flat entrance doors every year. That is Regulation 10 of the Fire Safety (England) Regulations 2022. In other buildings your fire risk assessment sets the frequency, and we suggest a professional inspection at least once a year. More on how often fire doors need inspecting.
The responsible person for the building. In a block of flats that is usually the freeholder, or the managing agent acting for them, and the cost normally goes through the service charge. Flat entrance doors depend on the lease: some put the door on the leaseholder, some keep it in the service charge. In an HMO or a rented house it is the landlord, and in a workplace it is the employer or whoever controls the premises. See who is responsible for fire doors in flats.
We are based in Luton and repair fire doors across Bedfordshire, Hertfordshire, Buckinghamshire and London, in blocks of flats, HMOs, schools, care homes and offices.
