About our fire stopping in Whitstable
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, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you have open linear gaps along the top of fire-resisting walls and penetration schedules that need working through, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Whitstable, that means joint design, primers and backing rod as standard.
Older buildings in towns like Whitstable have often been rewired and replumbed several times, with gaps around pipes and cables left after each change. Our applicators follow the product’s published detail for that wall or floor whenever fire-rated sealant is the chosen seal.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Maintenance after handover
To get the most from the new sealant:
- Treat an open penetration as a priority repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check risers and ceiling voids after each round of works
- Keep product data and details in the fire safety file
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If you have more than one building in Whitstable, they can often be done on the same visit. Tell us when the building is open and we will plan to suit.
- We ask for the product and detail your designer has specified.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Move anything stored against the joints
- Tell staff and tenants when we’ll be in
- Agree which areas must stay open

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Large openings beyond what any sealant detail covers
- Writing the fire-stopping specification
- Issuing fire ratings or certificates for seals
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.
What we seal
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Common problems we fix in Whitstable
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
It’s worth sending us details if you spot any of the following:
- Seals disturbed by maintenance and left open
- Openings left by services added after handover
- Improvised or mixed-product fire seals
- Old intumescent sealant that has split away
At a university such as University of Kent (4.2 miles south of Whitstable), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
What your quote should include
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?

Why it’s worth doing now in Whitstable
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. In Whitstable, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.
A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.

Questions about Whitstable
Do you take on work at healthcare sites like Whitstable and Tankerton Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can work at a site such as University of Kent fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you design or specify fire stopping?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.
Service penetrations in Whitstable buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Two care or nursing homes sit less than 2 miles from Whitstable. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified.
Where a unit on an estate such as Joseph Wilson Industrial Park (0.7 miles south-east of Whitstable), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a hotel such as The East Kent Hotel, under half a mile north-west of Whitstable, penetration seals are worth checking after any refit or services upgrade.

What the job involves on each surface
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
