Fire stopping in Forty Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
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 confirm material and size first and tell you if sealant isn’t the right product.
Fire stopping in Forty Green
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. If you have hidden openings found during inspections and openings left by services added after handover, we can put it right, on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows alike. A single leaking joint is often how a building in Forty Green first comes to us: we look at the rest while we are there and tell you what we find.
Smaller places such as Forty 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.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Forty Green
Would you work within a site like The Paddocks Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Forty Green too small for you to travel to?
No. Places such as Forty Green are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
What do BS EN 1366-3 and BS EN 13501-2 mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
Are you members of a third-party fire-stopping installer scheme?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. Where it isn’t required, we install the specified sealant to the maker’s details.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you design or specify fire stopping?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Service penetrations in Forty Green buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 38 miles from central London, Forty Green is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
Hospital estates such as The Paddocks Hospital (to the east of Forty Green) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Common problems we fix in Forty Green
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Site and facilities staff are often the first to spot these:
- Expanding foam used as fire stopping
- Penetration schedules that need working through
- Fire seals cut back for extra cables and never reinstated
- Head-of-wall gaps with no fire seal
Where a unit on an estate such as Bandet Way Industrial Estate, 3 miles to the west of Forty Green, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Questions to ask before you book

On site: what to expect
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out.

What sets the cost
Your fixed quote is built from the real scope. It allows for:
- The site’s rules and procedures
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
- Location, for remote and island sites
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Photos of the joints, close up and from further back
- The site address and postcode
- Whether the building will be occupied during the work
- How the joints are reached, and at what height
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email the details over.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Large openings beyond what any sealant detail covers
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.
