Fire stopping for commercial buildings in Colliers Green
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. 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 pipe penetrations, service gaps in risers and linear gaps at wall heads, and what we’re called in for most is fire sealant pulled out of the opening and hidden openings found during inspections. One point of contact handles commercial sealant work in Colliers Green from the first photos to the final walk-round, whether it’s one building or several.
A job near Colliers Green 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Older rural buildings around Colliers Green move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Fire-rated sealing for Colliers Green buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. There are a number of hotels within about 2 miles of Colliers Green. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
Schools such as Colliers Green Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Offices at parks like Hartley Dyke Business Centre (2.4 miles south of Colliers Green) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Colliers Green is about 7 miles south-east of Paddock Wood, in Kent.

What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
- Travel to remote or island sites
- Whether old sealant has to be cut out first
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Sending details for a quote
However big the job, the same details help:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- Specification clauses that apply
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or send details through our quote form to discuss it first.
Different surfaces, different methods
Metal pipes
Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.
Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. For a building around Colliers Green, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send 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.
- 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.
Before we start on site
- Make sure the joints can be reached
- Have the specification and drawings to hand
- Agree which areas must stay open

What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Signing off or certifying a building’s fire stopping
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Gaps in walls that were never built as compartment walls
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Joints and surfaces we work on
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
Your questions answered
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Colliers 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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Does your area include sites such as Hartley Dyke Business Centre, near Colliers Green?
Yes. Estates, retail parks and business parks around Colliers Green, Hartley Dyke Business Centre among them, are all within reach. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Do you work in Colliers Green?

Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
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.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Does weather matter for sealant work?
Outside, 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.
Common problems we fix in Colliers Green
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.
Most enquiries start with one or more of the following:
- Fire-rated sealant that has cracked or shrunk back
- Seals disturbed by maintenance and left open
- Penetration schedules that need working through
- Open linear gaps along the top of fire-resisting walls
Theatres, wards and plant rooms at sites like Benenden Hospital (to the south-east of Colliers Green) all have compartment walls crossed by services.
