Fire rated sealant in Swiss Cottage
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, with a record of the products and locations if you need one. We work on plasterboard & masonry, linear gaps and door frames, and the jobs we see most are gaps flagged on a fire risk assessment and standard silicone or caulk in a fire-stopping gap.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Swiss Cottage, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Surface by surface
Door frames
Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details.
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Fire rated sealant in Swiss Cottage: local notes
There are hotels and other places to stay in and around Swiss Cottage. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.
Letting a property close to South Hampstead station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like The UCL Academy? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building and we leave things clean and tidy. In Swiss Cottage, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Tell us if parking is tricky
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

Advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Don’t paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
- Include fire stopping when you schedule refits
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Common problems we fix in Swiss Cottage
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Signs it’s time to call us include:
- Cracked or shrunken fire-rated sealant
- Gaps flagged on a fire risk assessment
- Ordinary sealant used where a fire-rated product was needed
- Damaged fire sealant left by other trades
Swiss Cottage is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

- Who turns up on the day
- Which colour the sealant will be
- How long the guarantee is
- Whether they seal over old material or remove it
Swiss Cottage questions
Do you work for hotels and guest houses in Swiss Cottage?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can parking be tricky for a visit in Swiss Cottage?
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.
Are you insured?
Yes. Full insurance covers our work.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What fire rating will the seal have?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it, recording the locations and products.
What affects the quote in Swiss Cottage
We quote each job individually. These are the things that affect it:
- The size of the job
- Any working-time requirements on site
- How easy the joints are to reach
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- Photos by email, if that’s easy
- The type of property
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or email us.
Why act early in Swiss Cottage
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. 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.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Trusted Arbo and Everbuild sealants
- Old sealant always removed completely
- Every job guaranteed for a year
- Anti-fungal silicone where joints get wet
