Fire stopping in Ashurst
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on linear gaps at wall heads, pipe penetrations and cable penetrations, and what we are called in for most is open linear gaps along the top of fire-resisting walls and openings found when ceilings come down for a refit. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ashurst is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions around Ashurst 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Fire-rated sealing for Ashurst 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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 40 miles from Ashurst. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
Where a unit on an estate such as Hollands Lane Industrial Estate (1.8 miles east of Ashurst), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Older community buildings such as The Parish Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Ashurst is about 7 miles north of Shoreham-by-Sea, in West Sussex. Our applicators travel to Ashurst for work on service penetrations. Across West Sussex, 373 places are covered, including Ashurst. We also cover Brighton, around 11 miles from Ashurst.
We take on service penetrations across the BN44 postcode area, whatever the building. For a building on Church Lane and School Lane or nearby, send details and we’ll quote for service penetrations. Just outside Ashurst, we also work in Partridge Green (2 miles north-east), Dial Post (2 miles north-west), Wiston (2 miles south-west), Littleworth (3 miles north) and Ashington (3 miles west).

Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Ashurst are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- Let us know about inductions and permits

Advice
Other services in Ashurst
What we are called out for in Ashurst
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
If one of these sounds familiar, it’s time for a closer look:
- Unsealed openings around new pipes and cables
- Snag lists that include open service penetrations
- Head-of-wall gaps with no fire seal
- Fire-rated sealant that has cracked or shrunk back
Holiday works at schools like Ashurst CofE Primary School often leave service openings to seal before pupils return.
What to look for in a quote
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Can the work be phased to keep areas open?
Quoting for work in Ashurst
What shapes the price:
- Distance, for remote addresses
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
We can often quote from photos and a few details. Please tell us:
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- The type of building and who uses it
- Photos of the joints, close up and from further back
For a fixed quote, call 01277 525 020 or email drawings and photos. You can also send details through our quote form.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Foam or ordinary sealant is never a fire-seal repair
- Leave fire sealant to cure fully before covering it
- Include service cupboards in routine inspections
- Flag new cables with no seal around them
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.
How the job changes by surface
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and any bundle too large for sealant alone is flagged.
Metal pipes
Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.
Ashurst: questions and answers
What happens to BS 476 references for fire stopping in Ashurst?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
Will you take on work at estates like Hollands Lane Industrial Estate, close to Ashurst?
Yes. We cover Ashurst and the area around it, including industrial estates, business parks and retail parks such as Hollands Lane Industrial Estate. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Why deal with it now?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Around Ashurst, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
