Signs you need fire stopping in Stone
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.
Common reasons buildings call us in:
- Expanding foam used as fire stopping
- Open linear gaps along the top of fire-resisting walls
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
Older community buildings such as St Francis that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- Will RAMS and insurance details be available?
- Whether their applicators hold CSCS cards
Fire stopping in Stone, done properly
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. Each seal follows the manufacturer’s tested detail rather than guesswork. Site teams most often ask us about expanding foam used as fire stopping and head-of-wall gaps with no fire seal, across pipe penetrations, linear gaps at wall heads and service gaps in risers. Whether you call it commercial sealant work, mastic application or joint sealing, in Stone it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Stone, 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Stone as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around Stone, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Move anything stored against the joints
- Let us know about inductions and permits
- Point out any areas we must not close
Getting a fixed quote

After the work
Problems stay small when the joints are checked regularly. In particular:
- Include service cupboards in routine inspections
- Ask the designer to confirm details early on refits
- Get seals inspected before ceilings and boxing close
- Flag new cables with no seal around them
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

What the job involves on each surface
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do.
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Gaps in walls that were never built as compartment walls
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire risk assessments, a job for a competent assessor
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.
What we seal
- Small duct penetrations where the tested detail allows

FAQs: Stone
Is a smaller place like Stone outside your area?
No. Places such as Stone are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Stone?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How much does the work cost?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or email us.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
