About our fire rated sealant in Knatts Valley
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. If you’re dealing with holes left by a change of layout and gaps around pipes and cables through fire-resisting walls, we can put it right.
For holiday lets, converted business premises or a community building near Knatts Valley, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Allow for resealing whenever new services are run
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Check whether a sealant can be painted before decorating over it
- Ask every contractor to reseal any fire stopping they disturb
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we’re called out for in Knatts Valley
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.
Signs it’s time to call us include:
- Gaps filled with a product that is not fire-rated
- Sealant items on a fire risk assessment action list
- Gaps around pipes and cables through fire-resisting walls
- Fire stopping disturbed by later work
If you let a flat or house near Kemsing station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

When something else is needed
It helps to know what we can’t do:
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone is not the tested solution
- Fire risk assessments, which need a qualified assessor
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Workplaces and buildings in Knatts Valley
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 are given, installing the product to its tested details.
If you look after a building such as West Kingsdown CofE VC 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 Church of Saint Mary the Virgin, gaps around pipes and cables are worth checking after any building work there.

How the job changes by surface
Door frames
Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
