Fire rated sealant for homes and businesses in West Hampstead
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over. We work on plasterboard & masonry, door frames and flats & HMOs, and people most often call us about old fire sealant that has split or come away and fire stopping disturbed by later work.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in West Hampstead can’t close.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In West Hampstead, 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.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- On commercial sites, let us know about site rules

Advice
Landlord and commercial work in West Hampstead
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What affects the cost of fire rated sealant
Jobs vary more than people expect. What affects the quote:
- The amount of work
- Any mould that needs treating
- Whether the work is at height
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What we need to know
To make quoting easier, let us know:
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Whether it has been sealed before
Every job is quoted individually. Simply ring 0345 464 0079 or email us and describe the job.
Looking after it afterwards
To keep the joints looking good and working properly:
- Allow for resealing whenever new services are run
- Photograph sealed gaps before they’re covered up
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
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.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Commercial buildings in West Hampstead
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you let a flat or house near Finchley Road & Frognal station, any gap left by new services in shared walls should be closed with a fire-rated product. As a London address, West Hampstead can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Emmanuel Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.

What happens if it’s left?
If an assessor has flagged gaps, it makes sense to close them before 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, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Read what affects the cost or what customers say.
What we can’t put right
It helps to know what we cannot do too:
- Sign-off of the building, which sits with building control or your assessor

- Walls or floors that weren’t built to resist fire
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Where we work in West Hampstead
- Linear gaps
- Door frames
- Flats & HMOs
- Plasterboard & masonry
- Pipe & cable gaps
- Service penetrations
Different surfaces, different methods
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.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.
Your questions about fire rated sealant in West Hampstead
Do you take on hotel work around West Hampstead?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near Finchley Road & Frognal station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How long does fire rated sealant take?
A typical job takes anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. We’ll confirm how long when we quote.
Do you cover West Hampstead?
Yes. We cover West Hampstead and the rest of Greater London, as part of our work across South East England, London and Scotland. For a quote, phone 0345 464 0079 or email us.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What fire rating will the seal have?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
