Fire rated sealant in Forty Hill, done properly
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, one gap at a time. If you have open holes round services passing through fire walls and sealant items on a fire risk assessment action list, we can put it right, whatever the surface.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Forty Hill.

When to call us in Forty Hill
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
The problems people normally mention when they call include:
- Fire stopping disturbed by later work
- Open joints along the top of partitions
- Gaps left after a refit or conversion
- Standard silicone or caulk in a fire-stopping gap
As a London address, Forty Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

FAQs for Forty Hill
Can you do fire rated sealant in Forty Hill?
Yes. Our work covers London and the South East, and Forty Hill is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is parking an issue for fire rated sealant in Forty Hill?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is standard sealant good enough for a fire gap?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
What does intumescent mean?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Fire rated sealant in Forty Hill: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Managing a site like Worcesters Primary School? Then fire-stopping around service openings should be restored whenever new services go in. For buildings such as Jesus Church, gaps around pipes and cables are worth checking after any building work there.

How the visit works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Related advice
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- Fire doors that need new seals, closers or hardware
- A wall that isn’t a fire-resisting element to begin with
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Linear gaps
- Pipe & cable gaps
- Door frames
- Service penetrations
- Plasterboard & masonry
- Flats & HMOs
Different surfaces, different methods
Flats and HMOs
In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Ask which product was used before you paint
- Tell trades working in the building that fire seals must be put back
- Include hidden areas like risers in routine checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
What affects the quote in Forty Hill
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- The size of the job
- How easy the joints are to reach
- Which sealant suits the joint
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- If someone has resealed it before
- Where the property is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.
