The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In Berry's Green, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.

Fire rated sealant in Berry's Green
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you have linear gaps at the head of walls and cracked or shrunken fire-rated sealant, we can put it right, on plasterboard & masonry, flats & HMOs and pipe & cable gaps alike.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, 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 Berry's Green can’t close.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Do you need fire rated sealant in Berry's Green?
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.
Most people get in touch when they notice one of these:
- Linear gaps at the head of walls
- Cracked or shrunken fire-rated sealant
- Gaps flagged on a fire risk assessment
- Damaged fire sealant left by other trades
If you look after a church, hall or community building such as Church of St Peter and St Paul, gaps around pipes and cables are worth checking after any building work there.

Your questions about fire rated sealant in Berry's Green
Is parking a problem for a job in Berry's Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Chelsfield station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What information do you need?
A short description and the location. We will ask anything else we need to know.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
Honest limits
It helps to know what we cannot do:
- Problems with the door itself rather than the gap around the frame
- Fire risk assessments, which need a qualified assessor
- Issuing a fire rating or certificate for a building
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Aftercare tips
After the cure time, these simple habits help:
- Include fire stopping when you schedule refits
- Ask every contractor to reseal any fire stopping they disturb
- Don’t paint over fire sealant until it has cured
- Get damaged fire seals looked at promptly
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Surface by surface
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
Quotes for fire rated sealant in Berry's Green
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Whether the work is at height
- How many areas need sealing
- Whether there’s mould to deal with
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.
Commercial buildings in Berry's Green
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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Schools such as Cudham Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. As a London address, Berry's Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
