Fire stopping in Kingsnorth, done properly
We should be clear about what we do and don’t do. 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 buildings around Kingsnorth. Most enquiries involve service penetrations left open after M&E works and hidden openings found during inspections, across cable penetrations, service gaps in risers and linear gaps at wall heads.

Penetration seals near Kingsnorth
Kingsnorth is about 30 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. For England, the fire stopping of penetrations is dealt with in 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. What we install is set by the specification, and it goes in to the tested detail.
Schools such as The Hundred of Hoo Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On a hospital site such as Medway Maritime Hospital, 4.2 miles to the south-west of Kingsnorth, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Reviewing a building’s overall fire safety
- Construction that lacks the fire resistance the seal relies on
- Writing the fire-stopping specification
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

How the job changes by surface
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.

Signs you need fire stopping in Kingsnorth
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Unsealed penetrations discovered above suspended ceilings
- Service penetrations left open after M&E works
- Fire sealant pulled out of the opening
- Snag lists that include open service penetrations
Residences at universities like University of Greenwich - Medway, 3.4 miles to the south-west of Kingsnorth, have compartment walls that must be resealed whenever services change.
What your quote should include
- How the existing material will be dealt with
- What level of public liability insurance do they hold?
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?
Questions about Kingsnorth
Is hospital work, at somewhere like Medway Maritime Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Kingsnorth outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can the sealant be colour-matched?
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 will confirm the colours available for the specified product.
Do the same rules apply to fire stopping in Scotland?
Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Is BS 476 being phased out?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance, with clause 2.1.14 covering service penetrations.
On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Smaller jobs around Kingsnorth can be grouped with others nearby. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Before we start on site
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Work for main contractors and building owners
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 Kingsnorth can sit alongside others in a wider programme across Medway.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
