Specialist fire rated sealant for Chevening: careful preparation, the right product and tidy work. Call for a quick quote.
- Unsealed gaps around fire door frames
- Fire seals that have cracked with movement
- Gaps filled with a product that isn’t fire-rated
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep the record of products and locations with your fire safety documents
- Never patch a fire seal with standard sealant
- Allow for resealing whenever new services are run
- Flag any open gap you spot round a pipe or cable
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Fire rated sealant in Chevening
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. If you have gaps around pipes and cables through fire-resisting walls and open joints along the top of partitions, we can help, on linear gaps, flats & HMOs and plasterboard & masonry alike.
For a small place like Chevening, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Whatever the size of the job, it’s backed by our 12-month guarantee.

More services for Chevening
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Chevening needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

FAQs for Chevening
Do you cover smaller places like Chevening?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Dunton Green station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do you work in flats, HMOs and commercial buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you tell me how many minutes the seal will last?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.
Different surfaces, different methods
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist.
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
What affects the cost of fire rated sealant
Jobs vary more than people expect. What affects the quote:
- The number and length of the joints
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Whether the work is at height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
To help us quote quickly, let us know:
- Any access issues, like height or stairs
- Whether it has been sealed before
- What’s wrong with the joints now
- Roughly how big the job is
For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
What happens if it’s left?
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, so both the product and the method matter. Around Chevening, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Fire rated sealant around Chevening
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.
Community buildings like Church of St Botolph are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Dunton Green station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as Combe Bank School, fire-stopping around service openings should be restored whenever new services go in.
