Fire door inspection
the doorset, not just the leaf

A fire door only works as a doorset: leaf, frame, seals, hinges, glazing and closer working together. A painted hollow-core door with a sticker is not that.

Not legal advice. This page is general UK guidance only. Duties vary by tenure, nation and premises type. Confirm current requirements for your property and take professional advice where needed.

What inspectors actually look at

  • Gaps at the head, jambs and threshold — oversized gaps leak smoke and fire
  • Intumescent strips and cold-smoke seals still present and continuous
  • Three suitable hinges, not decorative two-hinge hangings
  • A closer that fully latches the door from any angle, including with a seal drag
  • Glazing and letter plates that belong on a fire doorset

Common defects on rented stock

Tenant-fitted extra locks, planed meeting stiles, missing seals after a repaint, and closers wound so weak the door sits ajar. Each one can undo the rating the door was sold with.

An FRA should say which doors are fire doors. The survey then checks those doorsets against that intent.

Repair versus replace

Seals, closers and some ironmongery can be replaced. A warped leaf, the wrong core, or a frame that was never a fire frame usually means a new doorset. We will not sell a seal kit as a miracle fix.

Fire door services or contact. Mention if the FRA already listed the doors — it shortens the quote.

Common questions

Can I plane a fire door that sticks?

Often that destroys the lipping and the certified gaps. Get the doorset surveyed before anyone takes a plane to it.

Do all internal doors in a house need to be fire doors?

No. The FRA and the layout decide. Escape routes, kitchens and protected stairs are the usual triggers.
