About fire-rated sealant
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, 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.
Commercial buildings in Cranbourne
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’re given, installing the product to its tested details.
Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Cranbourne Primary School, fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Ascot station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Cranbourne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Openings too large for sealant, which need batts, boards or another system
- Deciding what fire stopping a building needs
- Doors that aren’t fire doors in the first place
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Flats & HMOs
- Door frames
- Service penetrations
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
Why act early in Cranbourne
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Older cottages and farmhouses around Cranbourne can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Why us?
- Arbo and Everbuild products
- Full insurance on every job
- Tidy, careful work
- Any old sealant cut out fully, not covered over

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Photograph sealed gaps before they’re covered up
- Allow for resealing whenever new services are run
- File the fire-stopping record where your assessor can find it
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Different surfaces, different methods
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement.
Your questions about fire rated sealant in Cranbourne
Do you work for landlords with property near Ascot station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do fire rated sealant in Cranbourne?
Yes. We work across London and the South East, and Cranbourne is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
