How we handle fire stopping in Cox Green
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, ring 01277 525 020 or send photos by email with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve seals that don’t match their tested detail and fire seals cut back for extra cables and never reinstated, on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Looking for mastic applicators who cover Cox Green? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Converted and extended buildings around places like Cox Green can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Every job we finish is backed by a 12-month workmanship guarantee, in Cox Green as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Signing off or certifying a building’s fire stopping
- Writing the fire-stopping specification
- Plastic pipes whose detail calls for a collar or wrap
If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.
What we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
Our process
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a site in Cox Green, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

Advice
Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. In a smaller place such as Cox Green, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

FAQs: Cox Green
How does the move away from BS 476 affect penetration seals in Cox Green?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Could you schedule work at a campus like Berkshire College of Agriculture for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Fire stopping around Cox Green: points for this area
Approved Document B is the English guidance that covers fire stopping around 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. What we install is set by the specification, and it goes in to the tested detail. Cox Green has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.
Shop fits in centres such as Cliveden View Shopping Centre, 2.2 miles to the north of Cox Green, can bring new services through fire-resisting walls between units, which then need the specified seal. In a hotel such as Bear Hotel, 1.5 miles north-east of Cox Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Theatres, wards and plant rooms at sites like St Mark's Hospital (1.2 miles north of Cox Green) all have compartment walls crossed by services.

Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Drawings or a marked-up plan, if available
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, 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.
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, and each stage is agreed with your contact.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
