Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
About our fire stopping in Dukes Green
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Dukes Green. We work on service gaps in risers, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are unsealed penetrations discovered above suspended ceilings and head-of-wall gaps with no fire seal. Facilities teams, main contractors and managing agents in Dukes Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions around Dukes Green can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer.
Surfaces we seal

Penetration seals near Dukes Green
At about 50 miles from central London, Dukes Green is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail.
For a building such as The Parish Church of St Michael the Archangel, new heating or data runs are the usual reason penetrations need sealing. In a hotel such as Dean's Place Hotel, under half a mile north of Dukes Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Residences at universities like University of Brighton (to the west of Dukes Green) have compartment walls that must be resealed whenever services change.

Building owners, agents and FMs in Dukes Green
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Dukes Green can form part of a wider programme across East Sussex.
Why it’s worth doing now in Dukes Green
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. Older rural buildings around Dukes Green 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.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Common questions from Dukes Green clients
What happens to BS 476 references for fire stopping in Dukes Green?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is a hospital such as Chailey Heritage Marine Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How many days will you need on site?
It depends on the scope, but the work typically 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.
How long do sealant joints 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.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
