When to call us in Cotman's Ash
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
The most common problems we see are:
- Fire stopping disturbed by later work
- Open joints along the top of partitions
- Cracked or shrunken fire-rated sealant
- Gaps flagged on a fire risk assessment
Letting a property close to Kemsing station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common questions in Cotman's Ash
Can you help a landlord with a rental near Kemsing station?
Yes. We work for landlords and letting agents as well as householders. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Cotman's Ash for fire rated sealant?
Yes, Cotman's Ash is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
How long does fire rated sealant take?
A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. We’ll confirm how long when we quote.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
What does intumescent mean?
An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Can you tell me which gaps need fire stopping?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
When something else is needed
It helps to know what we cannot do:
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Fire rated sealant in Cotman's Ash: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Kemsing Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of Saint Mary the Virgin are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What the job involves on each surface
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point against the product’s tested range.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall.
