Fire-rated sealant in Westfield, East Sussex
Fire rated sealant across Westfield and nearby, with old sealant always removed completely and a 12-month guarantee.
- Gaps left after a refit or conversion
- Open holes round services passing through fire walls
- Fire seals that have cracked with movement
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Plan fire stopping into any work that goes through walls or floors
- Ask every contractor to reseal any fire stopping they disturb
- Photograph sealed gaps before they’re covered up
- Never patch a fire seal with standard sealant
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
How we handle fire rated sealant in Westfield
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have cracked or shrunken fire-rated sealant and gaps where walls meet ceilings or slabs, we can help, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Westfield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
There’s a 12-month guarantee on every job.

Commercial buildings in Westfield
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 are given, installing the product to its tested details.
For site and facilities teams at buildings such as Westfield School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like The Parish Church of St John the Baptist are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Doleham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Westfield is about 3 miles north of Hastings, in East Sussex. From the centre of Westfield to the outskirts, fire rated sealant is available for homes and businesses alike. Westfield is one of 289 towns and villages in East Sussex where we work for fire rated sealant. You can also see our page for Brighton, about 31 miles away.

Near you in Westfield
In Westfield, that means homes and buildings near Ark Helenswood Academy, among other places. Westfield’s nearest station is Doleham station, roughly 1.6 miles north-east of the centre.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. Around Westfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

How we quote for fire rated sealant
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- The type of sealant required
- Working hours on commercial sites
- The number of rooms or windows
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
To make quoting easier, please include:
- Whether it has been sealed before
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Westfield, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- 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.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit

Advice
How the job changes by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
