How we handle fire stopping in Marden's Hill
Facilities managers in Marden's Hill often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors, and the failures we are asked to look at most are damaged fire seals in risers and voids and non-fire-rated filler around services. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Marden's Hill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller places such as Marden's Hill 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, in Marden's Hill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Questions about Marden's Hill
Is Crowborough Business Park, near Marden's Hill, within your area?
Yes. Estates, retail parks and business parks around Marden's Hill, Crowborough Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Marden's Hill?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Marden's Hill can form part of a wider programme.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Cost factors for service penetrations
Each job is priced on its own details. The things that drive the figure:
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Backing rod, priming and other preparation
- Distance, for remote addresses
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Clear photographs of the problem areas
- Any dates the work must fit around
- Any specification or named product
- Whether the building will be occupied during the work
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or send photos by email.
Service penetrations in Marden's Hill buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Marden's Hill is about 31 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
Office fit-outs on sites such as Crowborough Business Park, 1.3 miles south-east of Marden's Hill, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Schools such as St John's Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
Marden's Hill is about 2 miles north-west of Crowborough, in East Sussex. Businesses, contractors and managing agents in Marden's Hill use us for work on service penetrations. Across East Sussex, 308 places are covered, Marden's Hill among them. For work in that direction, see our Brighton page.

Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Leave it or put it right?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. One visit to deal with every failing joint makes more sense than several trips to a place like Marden's Hill, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Common problems we fix in Marden's Hill
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Common reasons buildings call us in:
- Builders’ foam or ordinary silicone in compartment walls
- Improvised or mixed-product fire seals
- Penetration schedules that need working through
- Head-of-wall gaps with no fire seal
At a healthcare site like Crowborough War Memorial Hospital, 1.5 miles to the south-east of Marden's Hill, new services through compartment walls are a constant, and each needs the specified seal.
