01 / Active defense
Sensors start a roof and perimeter spray that runs off the grid, even when no one is home.

02 / Passive defense
Looks like paint. In heat, it swells into an insulating char that shields wood and eaves.

03 / Ember defense
Fine metal mesh stops embers at attic and foundation vents, the most common way they get in.

04 / Glazing defense
Heat-resistant film holds glass together so radiant heat and embers can't get inside.

05 / Landscape defense
Plant-based suppressant on landscaping, decks and fences stops embers from catching.

06 / Human defense
Year-round monitoring and a brigade that checks your system while you evacuate.

[ → ]How it works
One team handles the assessment, the work and the paperwork. No subcontractor hand-offs.
A retired firefighter walks your property and scores every path a fire could take.
You get a layer-by-layer plan, your readiness score and the expected insurance impact.
Licensed crews install each layer to spec, usually in days, not months.
A documented file for your broker, renewed with every maintenance visit.
