Fire Rated Sealant in Wilsley Green
Our applicators work in Wilsley Green on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.

Fire rated sealant for homes and businesses in Wilsley Green
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on service penetrations, plasterboard & masonry and door frames, and common reasons people get in touch are gaps flagged on a fire risk assessment and gaps where walls meet ceilings or slabs.
For holiday lets, converted business premises or a community building near Wilsley Green, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Every job is covered by our 12-month guarantee, wherever you are in Kent.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Tell trades working in the building that fire seals must be put back
- Include hidden areas like risers in routine checks
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Don’t paint over fire sealant until it has cured
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
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.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Wilsley Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Wilsley Green: your questions answered
Will you come out to Wilsley Green?
Yes, Wilsley Green is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Staplehurst station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Wilsley Green, along with the rest of our area.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used, so you have it on file.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
How long does fire rated sealant take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Around Wilsley Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Large holes that need a different fire-stopping system
- Problems with the door itself rather than the gap around the frame
- Construction that does not provide fire resistance on its own
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

What we are called out for in Wilsley Green
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
People usually contact us after spotting one of these:
- Gaps where walls meet ceilings or slabs
- Ordinary sealant used where a fire-rated product was needed
- New service routes left unsealed after building work
- Open gaps behind door architraves
Letting a property close to Staplehurst station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
Questions to ask before booking
- What guarantee comes with the work
- Whether they’re fully insured
- How the surfaces are prepared before sealing
- How much experience the applicator has
Fire rated sealant around Wilsley Green
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For buildings such as Church of St Dunstan, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Cranbrook Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.
