All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Cross Gate needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

Advice
How we handle fire rated sealant in Cross Gate
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you have joints picked up in a fire-stopping survey and open holes round services passing through fire walls, we can help.
Work in a small place like Cross Gate is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
Our work is backed for twelve months.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What we can’t put right
We won’t take on work that won’t last, so these are the limits:
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone is not the tested solution
- Certifying a building or signing off its fire safety
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What else we do in Cross Gate
Do you need fire rated sealant in Cross Gate?
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
If you can see any of these, it’s time to have the joints looked at:
- Joints picked up in a fire-stopping survey
- Ordinary sealant used where a fire-rated product was needed
- Damaged fire sealant left by other trades
- New service routes left unsealed after building work
If you let a flat or house near Amberley station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one 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.
Keeping the joints in good condition
So the new joints stay in good condition:
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
- Flag any open gap you spot round a pipe or cable
- Ask which product was used before you paint
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. In a small place like Cross Gate, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Commercial buildings in Cross Gate
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 work to the specification you’re given, installing the product to its tested details.
If you look after a building such as Amberley CofE Primary School, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as The Parish Church of St Michael and All Angels, gaps around pipes and cables are worth checking after any building work there.

Is Cross Gate in your area for fire rated sealant?

How long does fire rated sealant take?

Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
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 fit a product whose tested details meet it, recording the locations and products.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.
How much does fire rated sealant cost in Cross Gate?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
