How we handle fire stopping in Green Street Green
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Green Street Green. If you’re dealing with improvised or mixed-product fire seals and seals disturbed by maintenance and left open, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Green Street Green, that means joint design, primers and backing rod as standard.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in Green Street Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Confirm the product named in the specification
- Agree which areas must stay open
- Tell us what induction or permit system the site runs

Cost factors for service penetrations
A fixed quote reflects the actual work. It allows for:
- Induction, permit and paperwork requirements
- How much there is to seal
- Working within restricted access windows
- How much existing material needs removing
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- Specification clauses that apply
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call 01277 525 020 or send details through our quote form to discuss it first.
How the job changes by surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Fire stopping in Green Street Green: the local picture
Four care or nursing homes sit less than 2 miles from Green Street Green. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Schools such as Green Street Green Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Older community buildings such as St Mary's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Tenant changes at parks like Glebe Farm Business Park, 2.4 miles to the west of Green Street Green, bring new data and services, and openings through fire-resisting walls need the specified seal.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Green Street Green: questions and answers
What happens to BS 476 references for fire stopping in Green Street 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. Our part doesn’t change: the specified product, to its tested detail.
Would you work within a site like Orpington Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you work in Green Street Green?
Yes. Sites across Green Street Green are covered, and the same phone number covers every area.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
