How we handle fire stopping in Ansty
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance in Ansty and nearby. The enquiries we see most involve fire-rated sealant that has cracked or shrunk back and unsealed penetrations discovered above suspended ceilings, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers. A single leaking joint is often how a building in Ansty first comes to us: we look at the rest while we’re there and tell you what we find.
Rural conversions around Ansty can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

How the job changes by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
When to call us in Ansty
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Typical triggers for a call:
- Service penetrations left open after M&E works
- Head-of-wall gaps with no fire seal
- Seals that don’t match their tested detail
- Fire seals cut back for extra cables and never reinstated
Large healthcare estates like The Dene Hospital, 2 miles south of Ansty, change their services often, so penetration seals are worth checking after M&E work.
Questions to ask before you book
- How they’ll work around occupants
- Will RAMS and insurance details be available?
- Whether primer will be used where the manufacturer specifies it
- What level of public liability insurance do they hold?
Questions about Ansty
Is hospital work, at somewhere like The Dene Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
What does the BS 476 change mean for fire-rated sealant in Ansty?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do you cover Ansty?
Yes. We cover Ansty, and the simplest way to start is to speak to us on 01277 525 020 or use the quote form.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
- Walls or floors that aren’t fire-resisting to begin with
If you are not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer before you book.
Joints and surfaces we work on
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
Fire-rated sealing for Ansty buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Ansty takes in a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
For a site team at a college like Haywards Heath College, 2.5 miles north-east of Ansty, fire-rated sealing is best scheduled after the summer works. Offices at parks like Bolney Grange Business Park (1.7 miles south-west of Ansty) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Ansty is about 3 miles west of Haywards Heath, in West Sussex. We send applicators to Ansty for service penetrations. We work across 373 places in West Sussex. Sites around Brighton have their own page, about 11 miles away.
We cover the RH17 postcode districts for service penetrations. If your site is on Upton Drive, Bolney Road and Deaks Paddock or close by, send details and we will quote for service penetrations. Just outside Ansty, we also work in Abbotsford (2 miles south-east), Goddards Green (2 miles south), Hickstead (2 miles south-west), Jacob's Post (3 miles south-east) and World's End (3 miles south-east). A short drive away, we cover Crawley (8 miles north), Horsham (8 miles north-west), Haywards Heath (3 miles east), East Grinstead (11 miles north-east), Shoreham-by-Sea (12 miles south-west) and Lancing (13 miles south-west).
What’s near Ansty
The nearest railway station is Haywards Heath station, roughly 2.6 miles east. Other landmarks nearby include The Dene Hospital (2 miles south) and Cuckfield Museum (1.3 miles north-east). For a walk, there’s Blunts Wood and Paiges Meadow.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- How much existing material needs removing
- Induction, permit and paperwork requirements
- Quantities, in metres or numbers
- The size and state of each joint
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- Your programme or deadline
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- How the joints are reached, and at what height
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.

- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
