Finsbury: your questions answered
Do you take on hotel work around Finsbury?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Is parking an issue for fire rated sealant in Finsbury?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you carry out fire risk assessments?
No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We’ll give you a better idea when we quote.
About our fire rated sealant in Finsbury
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have sealant items on a fire risk assessment action list and ordinary sealant used where a fire-rated product was needed, we can help.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Finsbury, we agree timings and access before anything starts.
A one-year guarantee comes as standard, so you are covered after we have gone.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Issuing a fire rating or certificate for a building
- Assessing a building’s fire safety
- Problems with the door itself rather than the gap around the frame
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
Where we work in Finsbury
- Pipe & cable gaps
- Plasterboard & masonry
- Linear gaps
- Service penetrations
- Door frames
- Flats & HMOs
Different surfaces, different methods
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.
Workplaces and buildings in Finsbury
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. Finsbury has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Letting a property close to Old Street station? Then any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Prior Weston Primary School and Children's Centre are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

How to look after the new joints
Aftercare is simple:
- Check risers, ceiling voids and cupboards during building checks
- Store the list of sealed gaps with your building paperwork
- Photograph sealed gaps before they’re covered up
- Ask every contractor to reseal any fire stopping they disturb
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.
How it works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to 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 Finsbury. It helps if you can point us to a visitor permit or a bay close to the door.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces 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 if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we are working on

Related advice
What we’re called out for in Finsbury
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
These are the problems we’re asked about most:
- New service routes left unsealed after building work
- Fire stopping disturbed by later work
- Ordinary sealant used where a fire-rated product was needed
- Old fire sealant that has split or come away
Finsbury is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before booking anyone
- Who does the work, and how experienced they are
- Whether VAT is included
- Which sealant they’ll use, and why
- How the colour is chosen
How we quote for fire rated sealant
Jobs vary more than people expect. What affects the quote:
- How easy the joints are to reach
- Any working-time requirements on site
- The product the joint needs
- Any mould that needs treating
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- Where the property is
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
