About our fire rated sealant in Staples Corner
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We’re often asked to deal with seals cut through by electricians, plumbers or data installers and gaps where walls meet ceilings or slabs, across flats & HMOs, plasterboard & masonry and pipe & cable gaps.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Staples Corner, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
A one-year guarantee comes as standard.

How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes from a few hours to a few days, depending on the number of gaps and the access. In Staples Corner, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed 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 for your files.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
How to get a quote
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.

How to look after the new joints
So the new joints stay in good condition:
- Flag any open gap you spot round a pipe or cable
- Ask which product was used before you paint
- Photograph sealed gaps before they’re covered up
- Tell trades working in the building that fire seals must be put back
Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
FAQs for Staples Corner
Can parking be tricky for a visit in Staples Corner?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you take on hotel work around Staples Corner?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
How much does fire rated sealant cost in Staples Corner?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
What information do you need?
Let us know what needs doing and where. If we need more, we will ask.
Why it’s worth doing now in Staples Corner
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that does not depend on other work. 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 for homes in Staples Corner.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Commercial buildings in Staples Corner
There are hotels and other places to stay in and around Staples Corner. Hotel work can be planned room by room, with out-of-hours working where needed. 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.
For landlords with property near Brent Cross West station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Church of St John, older buildings that have had new heating or wiring often have service gaps worth checking.

What the job involves on each surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.
Flats and HMOs
Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product.
What we’re called out for in Staples Corner
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
It’s worth asking for a quote if you see:
- New service routes left unsealed after building work
- Fire seals that have cracked with movement
- Damaged fire sealant left by other trades
- Gaps where walls meet ceilings or slabs
For site and facilities teams at buildings such as Parkfield Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
