Fire stopping in St Mary Bourne
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. Most enquiries involve penetration schedules that need working through and openings found when ceilings come down for a refit, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads. Whoever orders the work in St Mary Bourne, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like St Mary Bourne, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Whoever the client is, the cover is the same: 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.

Common questions from St Mary Bourne clients
What happens to BS 476 references for fire stopping in St Mary Bourne?
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.
Would you work within a site like Andover War Memorial Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
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.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Doing it in-house
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Why it’s worth doing now in St Mary Bourne
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these and the building feels the difference. Halls, stores and units around places like St Mary Bourne may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Cost factors for service penetrations
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- Any access equipment needed
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
The more we know, the firmer the quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- The product your specification calls for
- The type of building and who uses it
- Access details, including height
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or send photos by email if you’d rather talk the job through.

Signs you need fire stopping in St Mary Bourne
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Any of the following is a good reason to get the joints checked over:
- Non-fire-rated filler around services
- Damaged fire seals in risers and voids
- Improvised or mixed-product fire seals
- Snag lists that include open service penetrations
For a school such as St Mary Bourne Primary School, penetration sealing fits best at the end of the summer works.
Questions to ask before you book
- Their approach to joint depth and backing
- What level of public liability insurance do they hold?
- How the existing material will be dealt with
- Is the sealant right for the movement and the substrate?
Where services cross fire walls in St Mary Bourne
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail. Central London is about 59 miles from St Mary Bourne. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
In a building such as Church of St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail. Wherever services are added at a hospital such as Andover War Memorial Hospital, 4.9 miles to the south-west of St Mary Bourne, the compartment line has to be made good with the specified product.
St Mary Bourne is about 5 miles north-east of Andover, in Hampshire. Anywhere in SP11, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. St Mary Bourne is one of 723 places we cover in Hampshire. Our Southampton page has more on work in that area, about 23 miles away.
We take on service penetrations across the SP11 postcode area, whatever the building.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. If others near St Mary Bourne need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
