About our fire stopping in Fullerton
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are fire-rated sealant that has cracked or shrunk back and openings left by services added after handover. For commercial sealant work in Fullerton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A job near Fullerton is normally planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Why act early in Fullerton
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Converted and older buildings near places like Fullerton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What else we do in Fullerton
Signs you need fire stopping in Fullerton
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Look out for the following:
- Service penetrations left open after M&E works
- Expanding foam used as fire stopping
- Hidden openings found during inspections
- Fire-rated sealant that has cracked or shrunk back
In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Fire-rated sealing for Fullerton buildings
In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Fullerton lies roughly 64 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
Hospital estates such as Andover War Memorial Hospital, 4.6 miles north of Fullerton, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Fullerton is about 4 miles south of Andover, in Hampshire. We cover commercial sites throughout Fullerton. Fullerton is one of 723 places in Hampshire on our list for service penetrations. Southampton is covered too, some 16 miles away.

Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Fullerton can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Warn occupants and staff about the work
- Move anything stored against the joints
- Send any specification or drawings in advance

Your questions answered
Is a hospital such as Andover War Memorial 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.
Is Fullerton off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What do BS EN 1366-3 and BS EN 13501-2 mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.
Is sealant suitable for all service openings?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, specified by your designer.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Foam or ordinary sealant is never a fire-seal repair
- Brief every trade that openings they make must be sealed
- File the specified details where the next contractor can find them
- Treat an open penetration as a priority repair
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
What the job involves on each surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
