Fire-rated sealant in Newtown, Kent
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in Newtown and across Kent. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps flagged on a fire risk assessment
- Damaged fire sealant left by other trades
- New service routes left unsealed after building work
How we handle fire rated sealant in Newtown
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you’re dealing with seals cut through by electricians, plumbers or data installers and open gaps behind door architraves, we can put it right, on linear gaps, service penetrations and flats & HMOs alike.
In a village or hamlet like Newtown, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Different surfaces, different methods
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- Access and height
- The product the joint needs
- How many areas need sealing
- The size of the job
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before work begins.
What to tell us for a quote
When you call or email, it’s useful to know:
- The rough size of the job
- A few photos by email, if you can
- The problem you’ve noticed
- Access, such as stairs, a lift or height
We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or drop us an email and describe the job.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Include fire stopping when you schedule refits
- Take pictures of fire stopping before ceilings or boxing go back
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
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.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Leave it or put it right?
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. In a small place like Newtown, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Fire rated sealant in Newtown: local notes
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Hever station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of the Holy Trinity, gaps around pipes and cables are worth checking after any building work there.

Related advice
When to call us in Newtown
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 isn’t always sealed again.
These are the problems we’re asked about most:
- Gaps around pipes and cables through fire-resisting walls
- Gaps left after a refit or conversion
- Damaged fire sealant left by other trades
- Gaps filled with a product that is not fire-rated
Schools such as Hever Church of England Voluntary Aided Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
