About our fire rated sealant in Sharpthorne
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. Common call-outs are for gaps around pipes and cables through fire-resisting walls and door frames with gaps between frame and wall, across service penetrations, flats & HMOs and plasterboard & masonry.
For holiday lets, converted business premises or a community building near Sharpthorne, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All of our work is guaranteed for twelve months, in Sharpthorne and everywhere else we cover.

What affects the quote in Sharpthorne
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Signs you need fire rated sealant in Sharpthorne
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Keep an eye out for these signs:
- Open gaps behind door architraves
- Fire stopping disturbed by later work
- Cracked or shrunken fire-rated sealant
- Linear gaps at the head of walls
If you look after a church, hall or community building such as St Margaret's Church, older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- What happens if they find a problem under the old sealant
- What insurance they hold
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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 fails, we can still redo it.
Sharpthorne questions
Is Sharpthorne in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Sharpthorne is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Sharpthorne?
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 standard sealant good enough for a fire gap?
No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service and we can apply it for you.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Sharpthorne, along with the rest of our area.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.

Why it’s worth doing now in Sharpthorne
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. Around Sharpthorne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?
- Tidy, careful work
- Anti-fungal sanitary silicone in wet areas
- Approved under the ARBOMaster scheme
- Any old sealant cut out fully, not covered over

Fire rated sealant in Sharpthorne: 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.
For landlords with property near East Grinstead station, any gap left by new services in shared walls should be closed with a fire-rated product. Managing a site like West Hoathly CofE Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building from start to finish. Somewhere like Sharpthorne needs a little journey planning: let us know about lanes, gates and parking. 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.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
How to prepare
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
