Radfield Fire Rated Sealant
We cover Radfield for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Cracked or shrunken fire-rated sealant
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Problems with the door itself rather than the gap around the frame
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Linear gaps
- Door frames
How we handle fire rated sealant in Radfield
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Common call-outs are for holes left by a change of layout and standard silicone or caulk in a fire-stopping gap, across flats & HMOs, service penetrations and linear gaps.
In a village or hamlet like Radfield, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All our work comes with our 12-month guarantee.

FAQs for Radfield
Do you work for landlords with property near Teynham station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Radfield?
Yes. Radfield is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you tell me which gaps need fire stopping?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Do you certify the fire stopping?
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.
Are you insured?
Yes. We’re fully insured.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. We use whichever the specification and tested details call for.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
What affects the cost of fire rated sealant
For a quick quote, just ask. What matters most is:
- Access and height
- When we can work, for business premises
- Any mould that needs treating
- How many rooms, windows or areas are involved
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
- Where the property is
- How we’d reach the joints
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved.
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. For a village or hamlet like Radfield, the journey is planned in advance: 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.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Related advice
What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. In a small place like Radfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why choose Mr Mastic in Radfield
- Any old sealant cut out fully, not covered over
- 12-month guarantee on every job

Fire rated sealant around Radfield
For seaside hotels, guest houses and holiday lets around Radfield, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.
For buildings such as Church of St Lawrence, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Teynham Parochial Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Teynham station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
