Fire stopping in South Down, done properly
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Site teams most often ask us about fire sealant pulled out of the opening and builders’ foam or ordinary silicone in compartment walls, across linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations. Most enquiries from South Down start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as South Down still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
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 spell out the cover before we begin.

On site: what to expect
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near South Down may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Arrange parking or a loading space
- Flag any permit to work we’ll need
- Clear stock, furniture or equipment away from the joints

What else we do in South Down
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Older rural buildings around South Down move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

When to call us in South Down
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Clients usually get in touch after noticing something like this:
- Hidden openings found during inspections
- Openings left by services added after handover
- Old intumescent sealant that has split away
- Penetration schedules that need working through
Residences at universities like University of Winchester (3.1 miles north of South Down) have compartment walls that must be resealed whenever services change.
Before you book anyone
- How they handle RAMS and site documents
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Signing off or certifying a building’s fire stopping
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
What we seal
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
South Down: questions and answers
Could you schedule work at a campus like University of Winchester for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Does your area include sites such as Hazeley Enterprise Park, near South Down?
Yes. Our area takes in South Down and its surroundings, with estates and business parks such as Hazeley Enterprise Park included. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you reseal penetrations after our M&E works?
Yes. Send the schedule or marked-up drawings and the specified product details. We can follow the services contractor floor by floor keeping pace with the programme.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Looking after the joints
A few simple habits keep the new joints working:
- Look above ceilings when tiles are lifted for other jobs
- Leave fire sealant to cure fully before covering it
- Get seals inspected before ceilings and boxing close
- Foam or ordinary sealant is never a fire-seal repair
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Penetration seals near South Down
At about 63 miles from central London, South Down is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Offices at parks like Hazeley Enterprise Park (1.5 miles north-east of South Down) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Hospital estates such as Wessex Hospital, 1.7 miles to the south-west of South Down, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
