Fire Door Maintenance 101: How Often Should Your Fire Doors Be Checked?

Fire doors do one job, but it's an important one. They hold back smoke and flames long enough for people to get out safely and for fire crews to get in. That's why fire door maintenance isn't something to leave until an inspector points out a problem. Regular checks are what keep a fire door doing its job when it matters most.

Why Fire Door Maintenance Matters

A fire door is not the same as an ordinary door once you get past the glance. It has intumescent seals, self-closing devices, smoke seals, and precise gaps around the frame – millimetres, not centimetres. Any one of these being damaged, painted over, or simply worn out reduces the amount of time the door can hold back fire. Regulations in the UK require landlords, employers, and building owners to keep fire doors in a state that will perform in an emergency, and that means routine fire door maintenance rather than a one-off check.

How Often Should Fire Doors Be Checked?

Guidance from bodies such as the British Woodworking Federation recommends checking fire doors in communal areas of blocks of flats every three months, and doors elsewhere in a building at least twice a year. High-traffic doors – ones that get opened and closed dozens of times a day – wear out faster and may need checking more often. If a building has recently had work done nearby, or if a door has taken repeated knocks from trolleys or furniture, it's worth checking it sooner rather than waiting for the next scheduled visit.

What a Certified Fire Door Inspection Involves

A proper check goes beyond looking at whether the door closes. A certified fire door inspection looks at the gaps around the door, the condition of hinges and seals, whether the door closes fully from any angle, and whether the glazing and any vision panels are still fire-rated and intact. It also checks that the door hasn't been altered in a way that voids its certification, such as extra holes drilled for locks or cables.

Signs Your Fire Doors Need Attention Now

A few things shouldn't wait for the next scheduled check. If a door doesn't close on its own, if there are visible gaps around the edges, if the seals are peeling or missing, or if the door has been propped open with a wedge for months, get it looked at straight away. These are the details that make the difference between a door that protects a building and one that only looks like it does.

Frequently Asked Questions

How often should fire doors be checked in a residential block?

Every three months is the standard recommendation for communal fire doors in blocks of flats, with a more thorough annual inspection alongside the quarterly checks.

Who is responsible for fire door maintenance?

In most buildings, the responsibility sits with the landlord, building owner, or the appointed "responsible person" under fire safety law, though day-to-day checks are often carried out by a facilities team or a fire door specialist.

Can I check a fire door myself?

Basic visual checks – gaps, seals, self-closing – can be done by anyone trained to spot the warning signs, but a full certified fire door inspection should be carried out by someone qualified to assess compliance.
