Compartments only work if every gap is sealed
One unsealed service penetration can let fire and smoke bypass a fire-resisting wall or floor. Fire stopping restores that resistance.
Since the Building Safety Act 2022, building owners and contractors need reliable, retrievable evidence of how passive fire protection was installed. We provide it as standard.

Fire stopping FAQs
What is fire stopping?
Fire stopping seals openings, gaps and voids where services pass through fire-resisting walls and floors. It restores the fire resistance of each compartment, so fire and smoke are contained and occupants have time to escape.
Why use a third-party certified installer?
Fire stopping is only as good as its installation. FIRAS certification means our installers and their work are independently audited, and every installation is traceable to the tested product and detail used.
Do you work on new build and refurbishment projects?
Yes. We work for main contractors on new build, refurbishment and remediation projects, as well as on occupied residential and commercial buildings.
What evidence will we receive at handover?
Each penetration is photographed, labelled and recorded in Onetrace with its location, product and installer, ready for your O&M manual and the building's golden thread of information.
Can you survey existing compartmentation?
Yes. We can survey existing fire stopping, record what we find and quote for remedial works where compartmentation has been breached.
