What we are called out for in Wintershill
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.
Look out for the following:
- Openings left by services added after handover
- Openings found when ceilings come down for a refit
- Fire-rated sealant that has cracked or shrunk back
- Fire seals cut back for extra cables and never reinstated
In a school such as Wyvern Technology College, fire-rated sealant goes in around service penetrations where it is specified.

Fire stopping for commercial buildings in Wintershill
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. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations, and the failures we’re asked to look at most are openings found when ceilings come down for a refit and fire-rated sealant that has cracked or shrunk back. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Wintershill it comes down to the same thing: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Wintershill 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.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Wintershill are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site

Advice
Keeping the joints sound
After handover, these steps help:
- Include service cupboards in routine inspections
- Ask which product is in place before decorating
- Brief every trade that openings they make must be sealed
- Get seals inspected before ceilings and boxing close
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.
Questions about Wintershill
Is hospital work, at somewhere like Moorgreen Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Wintershill too far out for you?
No. Places such as Wintershill are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you design or specify fire stopping?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal any opening with fire-rated sealant?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed, specified by your designer.
Penetration seals near Wintershill
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. At about 62 miles from central London, Wintershill is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
At a healthcare site like Moorgreen Hospital, which lies south-west of Wintershill, new services through compartment walls are a constant, and each needs the specified seal. For a unit at a site such as Deer Park Farm Industrial Estate, 1.4 miles west of Wintershill, new power or data runs between office and warehouse can breach a compartment wall.

Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Openings that need collars, wraps, batts or boards rather than sealant
- Writing the fire-stopping specification
- Signing off or certifying a building’s fire stopping
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer.

Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Building owners, agents and FMs in Wintershill
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
