Fire stopping in Green Street Green, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. We work on joints between fire-resisting walls and floors, service gaps in risers and linear gaps at wall heads, and what we’re called in for most is unsealed openings around new pipes and cables and head-of-wall gaps with no fire seal. A single leaking joint is often how a building in Green Street Green first comes to us: we look at the rest while we are there and tell you what we find.
Smaller places such as Green Street Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

FAQs: Green Street Green
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is Green Street Green too far out for you?
Not at all. Green Street Green is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
What will the job cost?

Compartment walls and floors in Green Street Green
Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Green Street Green is about 17 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For a hospital such as Darent Valley Hospital, 1.7 miles to the north-west of Green Street Green, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a building at a site such as Fawkham Business Park, which lies south-east of Green Street Green, a check of penetration seals after each fit-out is good practice.
Green Street Green is about 3 miles south-east of Dartford, in Kent. Looking for fire stopping in Green Street Green? We can help. Green Street Green is one of 931 places we cover in Kent for service penetrations. London is covered too, some 17 miles away.

Around Green Street Green

The closest station to Green Street Green is Longfield station, roughly 1.5 miles south-east. Other landmarks nearby include Bluewater (1.8 miles north) and Stone Castle (2.1 miles north). Green spaces nearby include Wansunt Pit and Sawyers Lake.
Looking after the joints
A few simple habits keep the new joints working:
- Don’t let anyone top up a fire seal with the wrong product
- Flag new cables with no seal around them
- Look above ceilings when tiles are lifted for other jobs
- Check with the data sheet before painting over fire sealant
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
What we can’t put right
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think before you book.
Joints and surfaces we work on
- Pipe penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows

What else we do in Green Street Green
What we are called out for in Green Street Green
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
Common reasons buildings call us in:
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
- Fire-stopping items raised at inspection or handover
- Fire seals cut back for extra cables and never reinstated
At a university such as University of Greenwich, which lies north of Green Street Green, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
