Fire rated sealant for homes and businesses in Hever
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on linear gaps, plasterboard & masonry and service penetrations, and common reasons people get in touch are sealant items on a fire risk assessment action list and old fire sealant that has split or come away.
If you have holiday lets, a converted barn used for business or a community building near Hever, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Fire rated sealant around Hever
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Hever Church of England Voluntary Aided Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Hever is about 6 miles north-east of East Grinstead, in Kent. Hever gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Hever is one of 922 towns and villages in Kent we cover for fire rated sealant. Our Crawley page covers work nearby (14 miles or so).

Different surfaces, different methods
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
When to call us in Hever
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
Most people get in touch when they notice something like this:
- Ordinary sealant used where a fire-rated product was needed
- Gaps flagged on a fire risk assessment
- Fire stopping disturbed by later work
- Gaps around pipes and cables through fire-resisting walls

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Hever questions
Is Hever within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Hever in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Hever is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Why deal with it now?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like Hever, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
