Fire door survey has found widespread failures across a building or estate in London

This is the one that lands on a managing agent's desk and ruins the afternoon. A survey comes back and it's not one dodgy door on the third floor - it's forty out of sixty flat entrance doors flagged, half the communal doors on the escape stairs failing to latch, cores breached, closers missing. Sometimes it's a housing association doing its rounds. Sometimes it's a fire risk assessor who's flagged doors as part of a wider report and told the responsible person to get a proper fire door survey done.

Whatever's brought you here, the pattern's usually the same - a block that's had no consistent oversight for years, and now the bill for that has landed all at once. We hear the same language every time: "how did nobody catch this sooner", "we didn't know it was this bad", "the whole block needs doing, not just a few."

What it might mean

There's rarely a single cause when failures show up across a whole building. A few things tend to overlap.

Age is usually part of it. Fire doors in a communal environment are typically expected to last 20-30 years, and a lot of post-war council stock across London is well past that now - original timber FD30 doors with perished intumescent strips and closers that gave up years ago.

It's also common to find no planned maintenance programme has ever existed. Nobody's been checking these doors on a rolling basis, so small issues - a dropped hinge, a missing seal - have quietly built up across dozens of doors at once, all surfacing on the same survey.

Sometimes there's a batch issue involved. Certain fire door products have been withdrawn or found not to meet their tested performance, and if a block was fitted out with one of those batches, it can explain why so many doors fail in a similar way. And in older buildings, repeated patch repairs over the years - done cheaply, without the right intumescent spec - may have quietly compromised the fire rating across multiple doors without anyone noticing until now.

None of these are confirmed just because the pattern fits. That's what a proper survey is for.

How urgent is it?

A building-wide replacement or remedial programme is planned work - it needs phasing, budgeting, and usually a conversation with leaseholders before anything gets signed off. You're not going to fix sixty doors in a week, and you shouldn't try to.

But within that programme, some doors can't wait for their slot in the phase plan. Any flat entrance door or communal door on an escape route that won't close, won't latch, or has a breached core needs treating as urgent regardless of where it sits in the wider schedule. Compartmentation only works if every door in the chain does its job - one door failing to close is one less barrier between a fire and the people trying to get past it.

So: plan the programme properly, but don't let the worst doors sit in a queue behind the ones that are just tired-looking.

What you can safely check

Before any professional turns up, it's worth doing a rough first pass yourself. Walk the block and note which doors physically won't close on their own, which have obvious gaps or damage to the leaf, and which sit on an escape route rather than a low-risk cupboard or store. Those are your priority group.

What you shouldn't do is try to fix everything yourself, or get a handyman patching intumescent strips and hanging new closers across the block without a plan. A fire door isn't just a door with a strip round the edge - the leaf, frame, hinges, seals and ironmongery all have to work together as a tested set. Get that wrong across forty doors and you've spent money creating a false sense of security.

Worth also checking whether the works trigger a Section 20 consultation if the building's leasehold - that affects timing and how the costs get communicated before anyone starts pulling doors off.

What we check

If there's already a survey report, we start there - going through the failure categories and severity grading door by door rather than treating the whole block as one problem. If no survey exists yet, that's the starting point: a full building fire door survey, with each door individually graded rather than a blanket "the block needs new doors" statement.

From there, doors get sorted into three groups - replace, repair, and monitor. Not every failed door needs pulling out; some can be brought back to a compliant state with the right remedial work, and that's a fraction of the cost of a full replacement. Others are too far gone or too poorly specified to bring back and need taking out properly.

That sorting is what turns a scary survey result into a phased programme with real numbers attached - costs per phase, which is exactly what's needed for a service charge budget or a Section 20 consultation.

How it's fixed

Once the doors are categorised, the fix usually runs in stages: doors that can't wait get dealt with first, then the wider communal fire door upgrades programme rolls through the rest in a planned order. Doors that just need remedial work - new intumescent strips, a proper closer, seals reinstated - get repaired rather than replaced where the leaf and frame still stack up. And once the programme's finished, it needs an ongoing maintenance schedule behind it, so the block doesn't end up back in this same position in five years' time.

Inspection reports and installation records get supplied as part of the works, which matters when the next fire risk assessment comes round or a leaseholder asks what they're actually paying for.

Call now if any door on an escape route won't close or latch

If that's happening on even one door in the block, that's not a phased-programme problem - that's now. Everything else - the wider survey, the replacement schedule, the Section 20 conversation - can be planned properly once the immediate risk is dealt with. Leave a whole estate's worth of failed doors sitting untouched and the next inspection will find the same list, just longer.
