Fire rated sealant for homes and businesses in Fontwell
We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. If you’re dealing with damaged fire sealant left by other trades and open gaps behind door architraves, we can put it right, on door frames, pipe & cable gaps and plasterboard & masonry alike.
If you have holiday lets, a converted barn used for business or a community building near Fontwell, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Big or small, you get the same one-year guarantee in Fontwell and across West Sussex.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Flag any open gap you spot round a pipe or cable
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Fire rated sealant around Fontwell
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, 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.
Schools such as Ormiston Six Villages Academy are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Fontwell needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Mention any parking rules near the property

How we quote for fire rated sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- The product the joint needs
- The size of the job
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
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, and we will explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- The problem you’ve noticed
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why it’s worth doing now in Fontwell
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Around Fontwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Common problems we fix in Fontwell
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
These are the problems we are asked about most:
- Gaps flagged on a fire risk assessment
- Fire stopping disturbed by later work
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
Rented homes near Barnham station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- Which sealant they’ll use, and why
- What guarantee comes with the work
- Who turns up on the day
- How the joint is cleaned and prepared
