Fire stopping in Hensting, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations, and the failures we’re asked to look at most are head-of-wall gaps with no fire seal and fire-stopping items raised at inspection or handover. Whether you call it commercial sealant work, mastic application or joint sealing, in Hensting it comes down to the same thing: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Hensting often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Whether the work must be split into stages
- Travel to remote or island sites
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- Access details, including height
- Any specification or named product
- Whether an asbestos survey exists
- Any dates the work must fit around
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or email a schedule or drawings.
Other services in Hensting
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep product data and details in the fire safety file
- Ask the designer to confirm details early on refits
- Brief every trade that openings they make must be sealed
- Look above ceilings when tiles are lifted for other jobs
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a single visit for a short list of penetrations, or a phased programme for a whole building. For work around Hensting, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Send your site hours and access windows
- Confirm the product named in the specification

Related advice
Signs you need fire stopping in Hensting
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Damaged fire seals in risers and voids
- Open linear gaps along the top of fire-resisting walls
- Improvised or mixed-product fire seals
- Non-fire-rated filler around services
Large healthcare estates like Wessex Hospital (to the west of Hensting) change their services often, so penetration seals are worth checking after M&E work.

Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Commercial clients in Hensting
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

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. Either way, we install the specified product to its tested detail. Hensting is about 62 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Office fit-outs on sites such as Wessex Business Park, 1 mile south-west of Hensting, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. In a hotel such as Marwell Hotel, 0.7 miles to the south of Hensting, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Your questions answered
Can work at a site such as University of Winchester fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How does the move away from BS 476 affect penetration seals in Hensting?
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.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Is Hensting in your area?
Yes. We cover Hensting, and you can call 01277 525 020 or send photos by email to get started.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
