Fire Door Installation in London

Common Problems We Find With London Fire Door Fitting

Most fire door problems we find in London aren't obvious until someone actually opens the door and looks properly. That's the trouble - a door can look fine, close fine, and still fail everything it's supposed to do in a fire.

The one we see most in converted terraces across East London and North London: a flat entrance door that was never fire rated to begin with. Someone's put in a nice-looking timber door during a refurb, no FD30S specification, no intumescent strip, no smoke seal - and it sails through until a survey or a Regulation 10 check flags it. That's a routine fail across period conversion stock, and it's usually the managing agent who finds out the hard way.

In post-war council blocks it's a different problem. The original FD30 doorsets are still there - but the intumescent strips have perished, the closers are knackered or missing, and the gaps around the frame have opened up well past what BS 8214 allows at head and jamb. A door that used to hold 30 minutes now might not hold ten.

Newer buildings aren't automatically safe either. We turn up to post-2000 developments with a properly certified doorset system and find the leaf's been drilled for ironmongery that was never tested with it - non-fire-rated handles, a closer that doesn't meet BS EN 1154, hinges that aren't the fire-rated three-hinge set the certification requires. One incompatible part and the whole certified assembly's compromised. That's an altered door leaf, and it invalidates the paperwork whether anyone notices or not.

Steel doors in plant rooms and commercial units get propped open with a fire extinguisher or wedge more often than you'd think - which defeats the point of an FD60 doorset entirely.

DIY fitting doesn't help. Fire door installation isn't like hanging a normal door - gap tolerances, frame fire stopping, hinge pads, certification traceability, it all has to line up with the tested scope or it's not a fire door anymore, it's just a door that looks like one. If you're wondering who can fit a fire door and have it actually hold up to inspection, that's the question worth asking before the work starts, not after a failed survey lands on your desk.

Fire Door Fitting Near Me - What We See Across London

Every borough throws up something different, and the age of the building tells you most of what you need to know before we even get the tape measure out. Interwar terraces in South West London still have their original timber doors on loft conversions that were never fire rated to begin with - nobody flagged it at building control because loft conversions are notorious for being signed off without anyone checking the door to the stairwell. West London's mansion blocks are a different problem again: solid, well-built structures from the 1930s, but the flat entrance doors have been swapped out over the decades by different leaseholders, so you'll walk a single corridor and find three different door specs, none of them matching the frame.

Purpose-built blocks are where FD30 doorset installation comes up most. A lot of post-war council stock in inner London still has its original 1960s and 1970s timber fire doors - and by now the intumescent strips have perished, the closers have seized or been removed altogether, and the leaf itself has usually been cut about for extra locks or letterboxes that were never part of the tested design. That's an altered door leaf, and once it's been modified outside its tested scope, it doesn't matter how good the door used to be - it's not doing its job.

Commercial premises and conversions bring their own issues. Central London office fit-outs regularly have steel fire doors to plant rooms propped open with a fire extinguisher - every day, without fail - because nobody's told the cleaning staff why that door matters. And period conversions across inner London routinely fail survey on the flat entrance door itself: nice looking door, non-rated, no FD30S certification anywhere on it, no closer to BS EN 1154 fitted.

Landlords going through HMO licence renewal hit this constantly - the door that's been fine for years suddenly isn't fine on paper. Managing agents on 11m-plus blocks run into it too, once they realise which doors actually fall under their Regulation 10 duties versus the leaseholders'. Get the doorset checked before someone else flags it for you.

Common Questions Before You Install Fire Doors in London

How long does it take to fit a fire door? Depends entirely on what's behind the old door. If the frame's sound and square, an FD30 doorset can go in within a day. If the frame's rotten, out of tolerance, or the opening needs fire stopping around the new doorset, you're looking at longer - plus making good the plaster and decoration afterwards. We've fitted flat entrance doors in Victorian conversions in an afternoon and spent two days on a single communal corridor door because the brickwork behind the old frame had moved. Anyone quoting you a fixed time before they've seen the opening is guessing.

What should I look for when choosing a fire door company? Ask for their certification - FIRAS or BM TRADA, not a general joinery qualification. Ask for sample installation certificates from previous jobs, not just a sales pitch. A proper installer checks certification traceability on every doorset, gives you a handover pack with your O&M documentation, and can tell you which tested scope or field of application your door falls under. If they can't answer that, they're guessing at compliance same as you.

FD30 or FD60 - which one do I need? That's not your call to make on price or preference. It comes from the building's fire strategy - flat entrance doors are typically FD30S, protected escape routes and higher-risk buildings often call for FD60, and plant rooms in commercial premises usually need it too. Approved Document B sets out where each rating applies. Get the wrong one specified and you've got a door that looks right and fails the one time it matters.

What does supply and fit actually cost? Varies with the door type, the rating, whether the frame's being replaced, the ironmongery spec, and how easy the access is. A composite fire door with CE-marked hardware costs differently to a solid timber core doorset with fire-rated glazing. What we don't do is quote blind over the phone - we look at the opening first.

Can I fit a fire door myself? There's no law against it. But a fire door only performs to its rating if it's installed to that tested scope - gap tolerances, three fire-rated hinges, the right intumescent strip and smoke seal fitting, a closer to BS EN 1154. Get any of that wrong and the certification's worthless, because it's the installation being tested, not just the leaf. New installs need intumescent strip replacement done to spec, not fitted by eye. Worth having someone who does this daily check it before it's signed off.
