Fire stopping for commercial buildings in Winterbourne
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with expanding foam used as fire stopping and unsealed openings around new pipes and cables, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Winterbourne is the same: the right product in a properly prepared joint.
Smaller places such as Winterbourne still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work in West Berkshire. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we will arrange a return visit.

Different surfaces, different methods
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Common problems we fix in Winterbourne
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Look out for the following:
- Damaged fire seals in risers and voids
- Open linear gaps along the top of fire-resisting walls
- Fire stopping installed outside its tested range
- Fire-rated sealant that has cracked or shrunk back
Holiday works at schools like Mary Hare School often leave service openings to seal before pupils return.
What your quote should include
- What the guarantee covers, and for how long
- Who will actually carry out the work
- Will failed sealant be removed rather than covered?
- Their approach to joint depth and backing
How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Winterbourne, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected
- Explain the parking and delivery arrangements

Questions we are asked in Winterbourne
Would you work within a site like West Berkshire Community Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Winterbourne, such as Red Shute Hill Industrial Estate?
Yes, sites like Red Shute Hill Industrial Estate are within our area, along with the rest of Winterbourne. A few photographs and the unit address let us price the work.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
What will the job cost?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or email a schedule or drawings with a description of the work.
Can you tell us what fire stopping our building needs?
No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Compartments and services around Winterbourne
In England, Approved Document B covers fire stopping of 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. At about 54 miles from central London, Winterbourne is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Halls and meeting rooms at places like Church of St James sometimes gain new services, and any compartment wall crossed needs the specified seal. For a unit at a site such as Red Shute Hill Industrial Estate (2.9 miles east of Winterbourne), new power or data runs between office and warehouse can breach a compartment wall.

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Reviewing a building’s overall fire safety
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
