Why Fire Doors Matter

Fire doors are vital life-saving barriers designed to prevent the spread of fire and smoke. Strategically placed throughout a building, they provide protected escape routes and buy valuable time for safe evacuation.

Fire doors can be:
FD30 and FD60 timber doors
FD90 and FD120 industrial doors
Smoke-rated door sets (for example FD30S)
Fully equipped with certified seals, closers and hardware

FAQs

Do fire doors need regular maintenance?

Yes. Wear and tear can affect seals, closers, hinges and alignment. Regular maintenance ensures continued compliance, proper operation and full fire protection performance.

How much does a fire door installation cost?

Costs vary depending on door type, rating (FD30 / FD60), hardware requirements and building layout. We provide clear, itemised quotations following a site survey.

How can I tell if my fire door is compliant?

Check for:

  • A valid certification label or plug
  • Correct gaps (2–4 mm)
  • Working self-closer
  • Intact intumescent and smoke seals
  • Certified hinges and hardware
  • If any part is missing or damaged, the door may fail compliance.

Can you paint or varnish a fire door?

Yes — as long as approved paint or varnish is used and the door’s certification label, seals and hardware remain untouched. Improper painting can compromise compliance.

Are fire doors required to have self-closing devices?

Most fire doors must have a working self-closer. This ensures the door closes automatically during a fire, maintaining compartmentation and protecting escape routes.

Do fire doors need intumescent strips?

Yes. Intumescent strips expand in heat to seal gaps around the door, preventing fire and smoke spread. Missing or damaged strips can invalidate the door’s performance.

What is the difference between FD30 and FD60 fire doors?

FD ratings refer to how long a fire door can withstand fire.

  • FD30 = 30 minutes
  • FD60 = 60 minutes
  • Higher-rated doors provide extended protection for more critical areas.

How often should fire doors be inspected?

Commercial and residential buildings typically require fire door inspections every 6 or 12 months, depending on the building type and traffic levels. High-use doors may need more frequent checks.

Where should fire doors be installed?

Fire doors should be installed in areas that help contain fire and smoke, such as stairwells, corridors, compartment lines, plant rooms, escape routes and between high-risk rooms and communal areas.

Do you need a certificate to install fire doors?

Yes. Fire doors must be installed by a certified professional to ensure they meet UK fire safety regulations. Proper installation guarantees correct clearances, hardware, seals and overall performance in the event of a fire.
