How we handle fire rated sealant in Michelmersh
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. We work on door frames, plasterboard & masonry and flats & HMOs, and people most often call us about unsealed gaps where pipes and cables go through a wall and gaps left after a refit or conversion.
Somewhere as small as Michelmersh, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Michelmersh, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip 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.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask every contractor to reseal any fire stopping they disturb
- Keep the record of products and locations with your fire safety documents
- Look in service cupboards and ceiling voids from time to time
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we 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.
Fire rated sealant around Michelmersh
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 St Mary, gaps around pipes and cables are worth checking after any building work there.

What affects the cost of fire rated sealant
We do not publish a price list. What we look at:
- The number of rooms or windows
- The size of the job
- How easy the joints are to reach
- The old material and how stubborn it is
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- The rough size of the job
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, phone 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.
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Deciding what fire stopping a building needs
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Plasterboard & masonry
- Flats & HMOs
- Door frames
- Pipe & cable gaps
- Linear gaps
- Service penetrations
When to call us in Michelmersh
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
The problems people generally mention when they call are:
- Open joints along the top of partitions
- Gaps left after a refit or conversion
- Unsealed gaps where pipes and cables go through a wall
- Fire seals that have cracked with movement
Rented homes near Mottisfont & Dunbridge station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
What to look for in a quote
- Whether you can choose the colour
- How the surfaces are prepared before sealing
- What happens if the job turns out different
- What guarantee comes with the work
Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Michelmersh: your questions answered
Can you do fire rated sealant in Michelmersh?
Yes, Michelmersh is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Mottisfont & Dunbridge station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available and agree one before any work starts.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why it’s worth doing now in Michelmersh
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Michelmersh, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- Over 20 years’ experience
- Tidy, careful work
- Approved under the ARBOMaster scheme
