Fire-rated sealant in Kingston Blount, Oxfordshire
Problem with your fire-stopping gaps in Kingston Blount? We cut out the old, prepare the joints and apply the right sealant.
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Joints picked up in a fire-stopping survey
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, 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.
Fire rated sealant for homes and businesses in Kingston Blount
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. Typical jobs include old fire sealant that has split or come away and joints picked up in a fire-stopping survey, across plasterboard & masonry, service penetrations and door frames.
For holiday lets, converted business premises or a community building near Kingston Blount, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job, large or small.

Your questions about fire rated sealant in Kingston Blount
Will you come out to Kingston Blount?
Yes, Kingston Blount is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Princes Risborough station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
What fire rating will the seal have?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will you assess my building’s fire safety?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Why deal with it now?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a small place like Kingston Blount, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

How the job changes by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.
What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Kingston Blount needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
Getting a quote
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Deciding what fire stopping a building needs
- Openings too large for sealant, which need batts, boards or another system
- Problems with the door itself rather than the gap around the frame
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Linear gaps
- Pipe & cable gaps
- Door frames
- Plasterboard & masonry
- Service penetrations
- Flats & HMOs
Common problems we fix in Kingston Blount
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
These are the problems we’re asked about most:
- Standard silicone or caulk in a fire-stopping gap
- Seals cut through by electricians, plumbers or data installers
- Sealant items on a fire risk assessment action list
- Unsealed gaps around fire door frames
Managing a site like Aston Rowant Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

What fire rated sealant looks like in Kingston Blount
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 are given, installing the product to its tested details.
For buildings such as Church of the Nativity of the Blessed Virgin Mary, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Princes Risborough station, any gap left by new services in shared walls should be closed with a fire-rated product.

Looking after it afterwards
So the new joints stay in good condition:
- Ask which product was used before you paint
- Keep pictures of seals that will be hidden
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
File the record of locations and products with your fire safety paperwork. 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.
