Fire stopping in Staines-upon-Thames
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with old intumescent sealant that has split away and damaged fire seals in risers and voids, we can help, whatever the surface. One point of contact handles commercial sealant work in Staines-upon-Thames from the first photographs to the final walk-round, whether it’s one building or several.
Towns the size of Staines-upon-Thames have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. New cabling or pipework through a fire-resisting wall leaves a gap that has to be made good with the specified product.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Different surfaces, different methods
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.

When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.
Surfaces we seal
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
Common problems we fix in Staines-upon-Thames
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
If one of these sounds familiar, it’s time for a closer look:
- Openings left by services added after handover
- Improvised or mixed-product fire seals
- Builders’ foam or ordinary silicone in compartment walls
- Open linear gaps along the top of fire-resisting walls
Offices at parks like Pine Trees Business Park, 0.6 miles to the west of Staines-upon-Thames, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Will you sign off the seals for us?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.
What do BS EN 1366-3 and BS EN 13501-2 mean?
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.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so right away rather than waste your time.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence. Scotland follows its own Technical Handbook, with clause 2.1.14 covering service penetrations.
