How we handle fire rated sealant in Kingsbury
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. Common call-outs are for old fire sealant that has split or come away and holes left by a change of layout, across pipe & cable gaps, flats & HMOs and plasterboard & masonry.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Kingsbury can’t close.
Whatever the size of the job, it’s backed by our one-year guarantee.

- Big openings where sealant alone isn’t the tested solution
- Deciding what fire stopping a building needs

Commercial buildings in Kingsbury
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
As a London address, Kingsbury can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Hendon station? Then any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as Kingsbury Green Primary School, service openings in fire-resisting walls need checking after any refurbishment.

FAQs for Kingsbury
Is parking an issue for fire rated sealant in Kingsbury?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you do fire rated sealant in Kingsbury?
Yes, Kingsbury is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
How much does fire rated sealant cost in Kingsbury?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.
Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Why us?
- Domestic, commercial and hotel work
- 12-month guarantee on every job
- More than 20 years in sealant work
- Sanitary silicone with an anti-fungal additive in wet areas
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Ask every contractor to reseal any fire stopping they disturb
- Include fire stopping when you schedule refits
- Keep the record of products and locations with your fire safety documents
- Do not fill fire-stopping gaps with ordinary foam or silicone
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

Surface by surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified room by room.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Kingsbury. A visitor permit or a nearby bay makes the visit run more smoothly.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
