What We Do
Passive Fire Protection That Saves Lives and Safeguards Buildings
We install certified fire-stopping systems to help contain fire and smoke, protect escape routes, and support your building’s compartmentation strategy. From new builds to remedials, we work to the highest standards every time.
We install, inspect and maintain fire doors to ensure they’re safe, compliant and ready when needed. Using accredited materials and detailed checks, we help you meet regulations and protect the people inside.

We carry out expert compartmentation surveys and support you with compliance strategy, documentation and remedial planning. From Building Safety Cases to urgent risk assessments, we make complex requirements manageable.

Why Passive Fire Protection Matters
Fires don’t give warnings, and when they break out, every second counts. Passive fire protection holds the line, giving people time to escape, containing the spread, and saving lives when active systems can’t.
Behind the scenes, we install certified systems that not only protect people but help you meet fire safety regulations and stay compliant under the latest legislation.
Because when safety’s on the line, there’s no room for shortcuts.
