About our fire stopping in Enfield Highway
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on cable penetrations, linear gaps at wall heads and service gaps in risers, and the failures we’re asked to look at most are seals that don’t match their tested detail and snag lists that include open service penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Enfield Highway, that means joint design, primers and backing rod as standard.
In a London area such as Enfield Highway, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Building owners and contractors get the same cover: 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.

Why it’s worth doing now in Enfield Highway
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Failed sealant in a building in Enfield Highway can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

What else we do in Enfield Highway
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Record which product was used where
- Check risers and ceiling voids after each round of works
- Agree the fire-stopping specification before services go in
- Have penetrations checked while they can still be seen
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.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
On site: what to expect
Occupied buildings need a little choreography. 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. All of Greater London is in the ULEZ, and kerbside space in Enfield Highway can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work
- Send any specification or drawings in advance

Compartment walls and floors in Enfield Highway
Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Refits at places like Enfield Highway Shopping Centre (to the south-west of Enfield Highway) often reroute services through walls between units. Theatres, wards and plant rooms at sites like St Michael's Community Hospital (1.8 miles west of Enfield Highway) all have compartment walls crossed by services. Colleges such as Capital City College (to the south of Enfield Highway) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Questions about Enfield Highway
Is Enfield Highway Shopping Centre, near Enfield Highway, within your area?
Yes, sites like Enfield Highway Shopping Centre are within our area, along with the rest of Enfield Highway. Send details of the unit and the work through our quote form for a quick quote.
Could you schedule work at a campus like Capital City College for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is the BS 476 change in 2029 relevant to fire stopping?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, with transitional arrangements set by the Government. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Is sealant suitable for all service openings?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution, as set out by the designer.
Surface by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.
Metal pipes
Heat travels along metal pipework, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Reviewing a building’s overall fire safety
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly.
