Fire stopping in Lynsore Bottom
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you have hidden openings found during inspections and damaged fire seals in risers and voids, we can put it right, whatever the surface. Whoever orders the work in Lynsore Bottom, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A job near Lynsore Bottom is typically planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
- Openings that need collars, wraps, batts or boards rather than sealant

FAQs: Lynsore Bottom
Is Lynsore Bottom off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Would you work within a site like Kent and Canterbury Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Which standards are fire seals tested to?
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.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. New services after M&E works often breach existing seals and we close them with the specified product.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When to call us in Lynsore Bottom
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
Clients typically get in touch after noticing one or more of the following:
- Non-fire-rated filler around services
- Seals that don’t match their tested detail
- Fire seals cut back for extra cables and never reinstated
- Hidden openings found during inspections
On a hospital site such as Kent and Canterbury Hospital, which lies north of Lynsore Bottom, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include
- Their plan for phasing and protecting the area
- How the existing material will be dealt with
- The named product and why it was chosen
- Health and safety accreditation such as CHAS

What else we do in Lynsore Bottom
Why it’s worth doing now in Lynsore Bottom
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Older rural buildings around Lynsore Bottom 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.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Aftercare for building managers
To get the most from the new sealant:
- Have penetrations checked while they can still be seen
- Keep general-purpose fillers away from compartment walls
- File the specified details where the next contractor can find them
- Ask the designer to confirm details early on refits
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match.
Our process
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Lynsore Bottom may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
- Send your site hours and access windows

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or send details through our quote form with what you know.
Advice
Penetration seals near Lynsore Bottom
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. At about 55 miles from central London, Lynsore Bottom is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.
For a building at a site such as Barham Business Park, which lies south-east of Lynsore Bottom, a check of penetration seals after each fit-out is good practice. Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Different surfaces, different methods
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
