Fire stopping in Thornborough
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
How we handle fire stopping in Thornborough
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. Most enquiries involve expanding foam used as fire stopping and improvised or mixed-product fire seals, on service gaps in risers, cable penetrations and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Thornborough first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Thornborough, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Leave it or put it right?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. One visit to deal with every failing joint makes more sense than several trips to a place like Thornborough. Photos of every joint help us quote for the whole job.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Where services cross fire walls in Thornborough
Central London is about 49 miles from Thornborough. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Holiday works at schools like Thornborough Infant School often leave service openings to seal before pupils return. At a healthcare site like Buckingham Community Hospital (3 miles west of Thornborough), new services through compartment walls are a constant, and each needs the specified seal.

Common questions from Thornborough clients
Would you work within a site like Buckingham Community Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Thornborough off your patch?
Not at all. Thornborough is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you approve fire stopping for building control?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.
Is fire stopping in Scotland covered by different guidance?
Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.
After the work
Regular inspection catches problems early. Specifically:
- Flag new cables with no seal around them
- Don’t let anyone top up a fire seal with the wrong product
- Brief every trade that openings they make must be sealed
- Leave fire sealant to cure fully before covering it
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Advice
When to call us in Thornborough
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Things that normally lead to an enquiry:
- Fire stopping installed outside its tested range
- Unsealed penetrations discovered above suspended ceilings
- Openings left by services added after handover
- Snag lists that include open service penetrations
At a university such as University of Buckingham, 2.7 miles west of Thornborough, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
