How we handle fire stopping in Wilmington
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. We work on pipe penetrations, cable penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and seals that don’t match their tested detail. Whether you call it commercial sealant work, mastic application or joint sealing, in Wilmington it comes down to the same thing: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Wilmington often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.
Surfaces we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
What affects the price in Wilmington
These are the things that shape the price:
- The total length or number of joints
- The site’s rules and procedures
- Travel to remote or island sites
- The size and state of each joint
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- The site address and postcode
- A wide shot and a close-up of the area
- The product your specification calls for
- Whether the building will be occupied during the work
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send photos by email.
Fire stopping around Wilmington: what changes locally
In England, Approved Document B covers fire stopping of 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. Our part stays the same: the specified product, installed to its tested detail. A 2-mile radius around Wilmington takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Theatres, wards and plant rooms at sites like Eastbourne District General Hospital (4 miles south-east of Wilmington) all have compartment walls crossed by services. In a building such as St Mary and St Peter's Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Wilmington is about 4 miles south-west of Hailsham, in East Sussex. We cover commercial sites throughout Wilmington, whether it’s a single job or part of a planned programme. We work across 308 places in East Sussex. Sites around Brighton have their own page, roughly 14 miles from Wilmington.
We cover the BN26 postcode districts. If your site is on The Street and Ades Field or close by, we can quote for service penetrations. Just outside Wilmington, we also work in Milton Street (1 mile south-west), Winton (2 miles west), Arlington (2 miles north), Berwick (2 miles north-west) and Lullington (2 miles south-west).

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for.

For a building around Wilmington, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.

Common questions from Wilmington clients
Can you seal penetrations in a hotel in Wilmington after a refit?
Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.
Can you work on a hospital site such as Eastbourne District General Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Signs you need fire stopping in Wilmington
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Common reasons buildings call us in:
- Improvised or mixed-product fire seals
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed penetrations discovered above suspended ceilings
- Fire-stopping items raised at inspection or handover
Holiday works at schools like Willingdon Community School often leave service openings to seal before pupils return.
Questions to ask before you book
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
- How the existing material will be dealt with
- Their plan for phasing and protecting the area
What happens if it’s left?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Older rural buildings around Wilmington 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.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
