Quick answer

A failed fire door inspection isn't a fine — it's a defect list with a clock on it. Most failures are repairs, not replacements: seals, closers, hinges and gaps get sorted for £250–£350 a door, a full refurbishment runs £950, and a new FD30S doorset £1,350–£1,500. Work through the report in priority order, keep the records, and the problem closes out. Ignore it and it becomes evidence.

First, read the grading

A competent inspection report grades every door: compliant, remedial (with the specific task — seals, closer, gaps, hinges) or replace (with reasons). That grading is your work plan. The common surprise is how it splits: on most blocks we inspect, the replace column is a small minority. Doors that look ropey usually fail on seals and gaps — the cheap end of the fix list.

If your report has no per-door grading, just a verdict, ask for a proper one before spending anything. Nobody should be buying doorsets off a report that doesn't say why.

The timeline after a fail

Can the building stay in use? Almost always yes. Stopping use of a building over door defects is prohibition-notice territory — reserved for serious, immediate risk, and rare. What's expected is a plan, visible progress and records.

  • Day 0 — report lands. Read the priority column first, not the total
  • First days — anything graded critical on an escape stair or high-traffic communal route goes to the front of the queue
  • Weeks 1–4 — remedial visits: seals, closers, hinge work, drop seals. A carpenter day (£625 +VAT) clears several doors
  • Then — replacements, if any, on lead time: doorsets take 2–6 weeks to arrive, so order early and fix everything else while you wait
  • Finally — re-check and certificates per door, and the door schedule updated so the quarterly checks have a clean baseline

Repair or replace: how the call gets made

Prices are our standard retail rates, +VAT. The repair-first logic isn't generosity — a certified door that can be brought back within its tested configuration is a better door than an unknown new leaf badly fitted.

Deadlines and enforcement

There's no single statutory number of days to fix a failed door. What exists is sharper than that: under the Fire Safety Order 2005 the responsible person must maintain fire doors as fire-resisting equipment, and under the Fire Safety (England) Regulations 2022 residential buildings over 11 metres re-check doors quarterly — so an unfixed defect resurfaces in writing every three months, each time with your name closer to it.

If a fire authority audits and finds defects unaddressed, the ladder runs: informal advice, then an improvement notice with a compliance date (typically 21 days or more), then prosecution — fines are unlimited, and directors can be personally liable. Insurers read the same reports. The cheapest place to stop that ladder is the first rung: a dated remedial plan and invoices that match it.

Closing it off properly

Every remedial visit ends with the door re-checked against the original defect and a pass certificate issued — our £350 remedial visit includes that re-check. The door schedule gets updated door by door, which matters more than it sounds: the schedule is what the quarterly checker, the fire risk assessor and any future auditor work from. A fixed door that isn't recorded as fixed still looks like a defect on paper.

We inspect and repair as separate line items, so the report stands alone and the remedial quote is priced defect by defect — you can tender it elsewhere and lose nothing. Recent work includes a 230-door two-school inspection and remedial programme completed over the summer holidays, and a 50-door schedule for a contractor on a government science campus.

Frequently Asked Questions

How long do I have to fix a failed fire door?
No fixed statutory period — but escape-route doors should move within days, and an improvement notice, if one ever arrives, typically gives 21+ days. In over-11m residential the quarterly checks mean any defect gets re-recorded every three months until it's closed.
Can the building stay open after a failed inspection?
Almost always yes. Prohibition notices are for serious, immediate danger and are rare. What's expected is prioritised action and records — not evacuation.
Do all failed doors need replacing?
No — replacement is usually the minority outcome. Most fails are seals, gaps, closers and hinges: £250–£350-a-door territory. Replacement wins only where the leaf is damaged, warped or has no provable certification.
Who's allowed to do the repairs?
Someone competent with fire doors specifically — remedials must keep the door inside its tested configuration, and the evidence trail (photos, certificates) matters as much as the carpentry. Ask any contractor how they'll document the fix.
What does reinspection cost?
Built into our remedial pricing — the £350 visit ends with the defect re-checked and a pass certificate. If a third party did the repairs, we re-inspect at normal per-door rates (£20–£30, from £20 a door on 20+ doors).
Can leaseholders be charged for the work?
In blocks, remedial costs normally flow through the service charge. Larger replacement programmes can trigger Section 20 consultation if any leaseholder's share tops £250 — we produce the spec and options to make that consultation straightforward.
