The process
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work normally takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Kenton. 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 earlier repairs to the joints
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

How we handle fire rated sealant in Kenton
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you’re dealing with gaps filled with a product that isn’t fire-rated and gaps around pipes and cables through fire-resisting walls, we can put it right.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Kenton needs to stay open, work can be planned outside normal hours.
All our work is covered by our 12-month guarantee, wherever you are in Greater London.

Common questions in Kenton
Can parking be tricky for a visit in Kenton?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is Kenton in your area for fire rated sealant?
Yes. We work across London and the South East, and Kenton is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Fire rated sealant in Kenton: local notes
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Kenton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Kenton is about 2 miles south of Stanmore, in Greater London. Across the HA3 area, our applicators can take on fire rated sealant. Kenton is one of 764 towns and villages in Greater London we cover. Our London page covers work nearby, about 11 miles away.
We cover every part of HA3, HA7 and HA1 for fire rated sealant and the streets around it. Fire rated sealant is available to properties on Retreat Close, Kenton Road and Woodgrange Avenue and the roads around them. Kenton sits on or near the A4006. We also cover the places around Kenton: South Kenton (1 mile south), Northwick Park (1 mile south-west), Greenhill (1 mile west), Wealdstone (1 mile north-west) and Harrow on the Hill (2 miles south-west).

What’s near Kenton
We work in homes and buildings around Uxendon Manor Primary School, The New Moon pub and Preston Park. For rail, the closest station is Kenton station, roughly 0.5 miles south-west. Other landmarks nearby include St. Anns (1.3 miles west) and Hilfield Castle (4.9 miles north). For a walk, there’s Masons Field and Northala Fields.
Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.

How to look after the new joints
After the cure time, these simple habits help:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Include fire stopping when you schedule refits
- Check whether a sealant can be painted before decorating over it
- Store the list of sealed gaps with your building paperwork
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Where we work in Kenton
- Service penetrations
- Door frames
- Pipe & cable gaps
- Flats & HMOs
- Plasterboard & masonry
- Linear gaps
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Signs you need fire rated sealant in Kenton
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Linear gaps at the head of walls
- Gaps left after a refit or conversion
- Standard silicone or caulk in a fire-stopping gap
Rented homes near Kenton station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
