How we handle fire stopping in Calbourne
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and unsealed joints where partitions meet the slab. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Calbourne, that means joint design, primers and backing rod as standard.
Barn and farm-building conversions near places like Calbourne often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Common questions from Calbourne clients
Is a hospital such as Whitecroft Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Calbourne?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.

Different surfaces, different methods
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Fire stopping around Calbourne: how the place shapes the job
Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a building at a site such as Porchfield Business Park, 2.3 miles north of Calbourne, a check of penetration seals after each fit-out is good practice. Theatres, wards and plant rooms at sites like Whitecroft Hospital (to the east of Calbourne) all have compartment walls crossed by services. Older community buildings such as All Saints' Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- Specification clauses that apply
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email the details over.
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Reviewing a building’s overall fire safety
- Signing off or certifying a building’s fire stopping
- Deciding what a wall or floor needs, which belongs to the designer
Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
What we seal
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Why it’s worth doing now in Calbourne
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. Halls, stores and units around places like Calbourne may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
