Fire stopping of openings and penetrations in England falls under Approved Document B. 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.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Openings that need collars, wraps, batts or boards rather than sealant
- Walls or floors that aren’t fire-resisting to begin with
- Approving the work on behalf of building control
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer before you book.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Pipe penetrations
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- Access and working height
- Phasing around occupants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Specification clauses that apply
- How the joints are reached, and at what height
- What the building is and how it’s used
- Photos of the joints, close up and from further back
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a site in Boyatt Wood, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
- Point out any areas we must not close

Related advice
Do you need fire stopping in Boyatt Wood?
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
Typical triggers for a call:
- Seals disturbed by maintenance and left open
- Openings left by services added after handover
- Non-fire-rated filler around services
- Fire sealant pulled out of the opening
For an estates team at a campus like University of Southampton, which lies south-west of Boyatt Wood, summer M&E works are usually followed by a round of penetration sealing.
What your quote should include
- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?
- Who will actually carry out the work
- Are they CHAS accredited or on Constructionline?

FAQs: Boyatt Wood
Can you work around term dates at a campus such as University of Southampton?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Boyatt Wood too small for you to travel to?
No. Places such as Boyatt Wood are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is fire stopping in Scotland covered by different guidance?
Our area runs from Greater London and the South East to every part of Scotland. 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.
Which standards are fire seals tested to?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How the job changes by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables, so we check before sealing.
