Frequently asked questions about fire stopping in Chelmsford

What is fire stopping in Chelmsford?

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 Chelmsford?

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 Chelmsford?

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 Chelmsford?

Yes. Our engineers cover all of Chelmsford and the surrounding Essex 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 Chelmsford?

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

Do you offer ongoing maintenance in Chelmsford?

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