Frequently asked questions about fire stopping in London

What is fire stopping in London?

Fire stopping is the sealing of gaps and penetrations through fire-resisting walls and floors using systems tested to maintain the fire and smoke resistance of the original element. It is how the building's compartmentation strategy is held together over its life.

What standards does your fire stopping meet in London?

Our installations follow third-party tested details to BS EN 1366-3 (penetration seals) or BS EN 1366-4 (linear gap seals), with installation practice aligned to FIRAS, IFC Certification and ASFP guidance.

Why can't builders just use expanding foam in London?

Expanding foam has no fire test evidence for the substrates and services it is being applied to. Building control, insurers and the Building Safety Regulator require third-party tested systems for fire-rated penetrations.

Do you cover the whole of London?

Yes. Our engineers cover all of London and the surrounding Greater London area. We provide free site surveys and can typically attend within 24–48 hours of your enquiry.

How quickly can you attend a site in London?

We aim to respond to all enquiries within 24 hours. For fire stopping projects in London, we can usually arrange a site survey within 2–3 working days.

Do you offer ongoing maintenance in London?

Yes. We offer scheduled servicing and maintenance contracts for all systems we install in London. This ensures your equipment stays compliant and fully operational year-round.
