Fire stopping in Lions Green
Facilities managers in Lions Green often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with head-of-wall gaps with no fire seal and hidden openings found during inspections, we can put it right, on service gaps in risers, pipe penetrations and linear gaps at wall heads alike. Searching for sealant specialists in Lions Green? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Rural conversions around Lions Green can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When to bring in a specialist
For most general trades, sealant is a sideline. 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.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Why deal with it now?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. One visit to deal with every failing joint makes more sense than several trips to a place like Lions Green, rather than one at a time. Photos of every joint help us quote for the whole job.
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Questions we are asked in Lions Green
Is Merrydown Business Park, near Lions Green, within your area?
Yes. We cover Lions Green and the area around it, including industrial estates, business parks and retail parks such as Merrydown Business Park. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
What happens to BS 476 references for fire stopping in Lions Green?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.
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.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Surface by surface
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
What we are called out for in Lions Green
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Most enquiries start with something like this:
- Expanding foam used as fire stopping
- Unsealed penetrations discovered above suspended ceilings
- Unsealed openings around new pipes and cables
- Improvised or mixed-product fire seals
Older community buildings such as The Parish Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What to look for in a quote
- Whether their applicators hold CSCS cards
- How joint depth will be controlled
- Will RAMS and insurance details be available?
- Which product they’ll use, and why it suits the joint
After the work
Regular inspection catches problems early. Specifically:
- Have penetrations checked while they can still be seen
- Brief every trade that openings they make must be sealed
- File the specified details where the next contractor can find them
- Don’t let anyone top up a fire seal with the wrong product
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
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.
Where services cross fire walls in Lions Green
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Lions Green lies roughly 41 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
Office fit-outs on sites such as Merrydown Business Park, 1.2 miles to the south-east of Lions Green, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Wherever services are added at a hospital such as Hellingly Hospital Railway, 4.1 miles south-east of Lions Green, the compartment line has to be made good with the specified product.
