Fire rated sealant for homes and businesses in Radfall
Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. Common call-outs are for damaged fire sealant left by other trades and ordinary sealant used where a fire-rated product was needed, across door frames, linear gaps and plasterboard & masonry.
If you have holiday lets, a converted barn used for business or a community building near Radfall, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Radfall needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Commercial buildings in Radfall
For seaside hotels, guest houses and holiday lets around Radfall, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.
For landlords with property near Chestfield & Swalecliffe station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as The Whitstable School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Leave it or put it right?
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again once someone inspects it. In a small place like Radfall, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

FAQs for Radfall
Do you cover Radfall for fire rated sealant?
Yes, Radfall is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Do you work for landlords with property near Chestfield & Swalecliffe station?

What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Can new sealant go over the old?
No, it will not last. 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 tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Keep the record of products and locations with your fire safety documents
- Allow for resealing whenever new services are run
- Include hidden areas like risers in routine checks
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
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.
