Fire stopping in Seaton, done properly
Facilities managers in Seaton 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 using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. The enquiries we see most involve fire stopping installed outside its tested range and unsealed joints where partitions meet the slab, across service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Seaton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a smaller site near Seaton, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
A 12-month guarantee applies to all our work in Kent. Should something we installed fail, call the office on 01277 525 020 or use the quote form and we will come back to it.

For managing agents and facilities managers
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Seaton can sit alongside others in a wider programme.
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Around Seaton, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. For work around Seaton, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
- Move anything stored against the joints
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

What we’re called out for in Seaton
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Clients normally get in touch after noticing something like this:
- Damaged fire seals in risers and voids
- Snag lists that include open service penetrations
- Head-of-wall gaps with no fire seal
- Openings left by services added after handover
For a building such as Church of St Andrew, new heating or data runs are the usual reason penetrations need sealing.

Compartment walls and floors in Seaton
Central London is about 57 miles from Seaton. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. 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. Either way, we install the specified product to its tested detail.
Where a unit on an estate such as Wingham Industrial Estate, which lies south-east of Seaton, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. At a university such as Canterbury Christ Church University (4.3 miles west of Seaton), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Seaton is about 5 miles east of Canterbury, in Kent. Seaton sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, Seaton among them. London is covered too, some 57 miles away.

What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Deciding what a wall or floor needs, which belongs to the designer
- Approving the work on behalf of building control
- Construction that lacks the fire resistance the seal relies on
If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Joints and surfaces we work on

FAQs: Seaton
What happens to BS 476 references for fire stopping in Seaton?
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. Our part doesn’t change: the specified product, to its tested detail.
Is Seaton off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Surface by surface
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
