Fire Doors

Commercial Fire Door Repairs and Maintenance

We repair fire doors in commercial buildings: offices, schools, care homes, hotels, warehouses and shops. Seals, closers, gaps, hinges and glazing are fixed to BS 8214, every door is photographed before and after, and each one is certified on completion. We price from your inspection report and work out of hours where the building needs it.

Commercial fire door repairs we carry out

  • New intumescent strips and smoke seals
  • Closers adjusted, refixed or replaced so every door latches from any angle
  • Gaps brought back within tolerance by re-hanging, frame re-sets, lipping or drop seals
  • Fire-rated hinges, locks, latches, push plates and panic hardware
  • Fire-rated glazing and beads fitted to the tested detail
  • Hold-open devices that release on the fire alarm, tested and certified
  • Signs fitted where they are missing

The full list of faults we fix is on our fire door repairs and remedial works page.

Buildings we work in

  • Offices and business parks, with work in the evening or at weekends so staff are not disturbed.
  • Schools and academies, planned for half terms and holidays.
  • Care homes and healthcare, one corridor at a time so residents stay protected.
  • Hotels, room by room around bookings.
  • Warehouses and industrial units, including large double doors and doors on escape routes.
  • Shops and restaurants, outside opening hours.

Fixed price, certified result

We price every door from your report or photos, so you can see the cost door by door and budget across sites. The price is fixed for a compliant, certified result. If a door we have repaired fails a fire door inspection within 12 months, on anything we fitted or adjusted, we come back and put it right free of charge.

Maintenance contracts

Commercial buildings need their fire doors checked regularly under the fire risk assessment. A maintenance contract books the checks, fixes small faults on the same visit and keeps your door register up to date. See fire door maintenance and servicing contracts.

Frequently Asked Questions

Can you repair fire doors outside business hours?
Yes. We plan evening, weekend and holiday work for offices, schools and shops so the building keeps running and the doors are back in service the same day.
Do you work from another company's inspection report?
Yes. Send the report and any photos and we price every door from it. If something on site differs from the report, we tell you before doing anything extra.
What paperwork do we get?
A certificate of conformity for each door and a before and after photo record, ready for your fire risk assessment, insurer and fire service visits. Need the doors checked first? See fire door inspections.
