Why it’s worth doing now in East Dean
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Older rural buildings around East Dean 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.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

About our fire stopping in East Dean
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. Where there isn’t one, the designer or fire engineer needs to set one first. The enquiries we see most involve improvised or mixed-product fire seals and fire-stopping items raised at inspection or handover, on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations. A specialist sealant contractor works differently from a general builder: on jobs in East Dean, preparation and product choice get the time they need.
Around smaller places like East Dean, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Service penetrations in East Dean buildings
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. Either way, we install the specified product to its tested detail. Central London is about 53 miles from East Dean. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
At a university such as University of Brighton, 2.5 miles east of East Dean, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. In a building such as The Parish Church of St Simon and St Jude, any service penetration through a fire-resisting wall should be sealed to the specified detail. On a hospital site such as Eastbourne District General Hospital (3.3 miles north-east of East Dean), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
East Dean is about 4 miles south-west of Eastbourne, in East Sussex. We cover commercial sites throughout East Dean, whether it’s a single job or part of a planned programme. Across East Sussex, 308 places are covered, East Dean among them. Brighton is covered too, some 16 miles away.
Work on service penetrations is covered throughout BN20, for business premises of every kind. Among the streets we cover are Lower Street, Went Way and Gilberts Drive. If your building is just outside East Dean, we cover Friston (1 mile north-east), Birling Gap (1 mile south), Jevington (2 miles north), Meads (3 miles east) and Old Town (3 miles east). Bigger towns within reach include Eastbourne (4 miles north-east), Bexhill-on-Sea (13 miles north-east), Seaford (4 miles west), Lewes (12 miles north-west), Hailsham (8 miles north) and Uckfield (15 miles north).

Different surfaces, different methods
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any outside it are raised with you.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

Aftercare for building managers
Once the work is signed off, these steps help:
- Ask the designer to confirm details early on refits
- Include service cupboards in routine inspections
- Get seals inspected before ceilings and boxing close
- Don’t let anyone top up a fire seal with the wrong product
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: for instance 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.
From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like East Dean are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Move anything stored against the joints
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space

Advice
Common questions from East Dean clients
Is East Dean too far out for you?
No. Places such as East Dean are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What does the BS 476 change mean for fire-rated sealant in East Dean?
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.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Reviewing a building’s overall fire safety
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
If in doubt, phone 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
