Fire stopping in Foxbury
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 have fire seals cut back for extra cables and never reinstated and open linear gaps along the top of fire-resisting walls, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Foxbury, preparation and product choice get the time they need.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Walls or floors that aren’t fire-resisting to begin with
- Deciding what a wall or floor needs, which belongs to the designer
- Plastic pipes whose detail calls for a collar or wrap
If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal
- Pipe penetrations
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Check with the data sheet before painting over fire sealant
- Keep general-purpose fillers away from compartment walls
- Look above ceilings when tiles are lifted for other jobs
- Report damaged or disturbed seals as soon as they’re spotted
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
When to call us in Foxbury
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
If one of these sounds familiar, it’s time for a closer look:
- Openings found when ceilings come down for a refit
- Penetration schedules that need working through
- Openings left by services added after handover
- Damaged fire seals in risers and voids
Shop fits in centres such as Nugent Retail Park (to the south-east of Foxbury) can bring new services through fire-resisting walls between units, which then need the specified seal.
Before you book anyone
- What site paperwork they can supply
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?
Fire stopping around Foxbury: points for this area
In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. Foxbury has 16 care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
For a site team at a college like Bird College, 1.2 miles north-east of Foxbury, fire-rated sealing is best scheduled after the summer works. Tenant changes at parks like Crayfields Business Park (to the south-east of Foxbury) bring new data and services, and openings through fire-resisting walls need the specified seal.

Different surfaces, different methods
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. For a job in Foxbury, access comes first. Send the building rules and access times with your enquiry.

Common questions from Foxbury clients
What happens to BS 476 references for fire stopping in Foxbury?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you work on a hospital site such as Queen Mary's Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
