Fire rated sealant in Gossops Green
Until it’s heated, intumescent sealant behaves like an ordinary sealant; 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, so we follow the tested detail for each one. If you have sealant items on a fire risk assessment action list and gaps filled with a product that isn’t fire-rated, we can help, on linear gaps, flats & HMOs and service penetrations alike.
In a smaller place like Gossops Green, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
Whatever the size of the job, it’s backed by our one-year guarantee in Gossops Green and across West Sussex.

Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. In a smaller place like Gossops Green, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Do you need fire rated sealant in Gossops Green?
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where walls meet ceilings or slabs
- Ordinary sealant used where a fire-rated product was needed
- Seals cut through by electricians, plumbers or data installers
- Joints picked up in a fire-stopping survey
Schools such as Ifield Community College are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

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.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
What affects the quote in Gossops Green
There’s no set price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- Whether the work is at height
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- A few photos by email, if you can
- The rough size of the job
- How we’d reach the joints
- Any previous sealing or DIY work
For a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before we start.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are. In a smaller place like Gossops Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Tell us about any water getting in
Getting a quote
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
Advice
Common questions in Gossops Green
Do you cover Gossops Green for fire rated sealant?
Yes. We work across London and the South East, and Gossops Green is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Ifield station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Where do you work from?
Mr Mastic is based in Crawley. We cover Gossops Green and the rest of West Sussex.
How do I get a quote for fire rated sealant in Gossops Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
What does intumescent mean?
An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Issuing a fire rating or certificate for a building
- Fire risk assessments, which need a qualified assessor
- A wall that is not a fire-resisting element to begin with
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Plasterboard & masonry
- Flats & HMOs
- Door frames
- Pipe & cable gaps
- Linear gaps
- Service penetrations
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Other services in Gossops Green
Fire rated sealant around Gossops Green
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. Crawley, which Gossops Green is part of, is one of England’s post-war new towns. Crawley was planned with its own industrial and business areas, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere.
Community buildings like St Peter's are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Letting a property close to Ifield station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
