What we offer

Protection built for the place you actually live.

We specialize in exterior fire defense systems designed to help protect homes and businesses in any environment. Our systems are built to create a defensive barrier around your property, helping reduce the risk of ignition from embers, radiant heat, and advancing flames.

Residential Homes

Single and two-story homes, defended at the roofline and perimeter where embers land first.

Commercial Buildings & Properties

Multi-family and commercial sites that need dependable coverage over a larger footprint.

Rural, Hillside & Canyon Properties

The hard-to-reach places fire reaches first. Systems engineered for terrain, wind, and brush.

High-Value Assets

Boat storage, equipment, and irreplaceable property that deserves added protection.

About us

We take fire protection personally.

Fire Defense Systems was established to enable property owners in fire-prone regions to adopt a more proactive stance toward protection. Fires don't give warnings. And when they hit, traditional protection isn't enough.

We concentrate on exterior fire defense systems designed to safeguard residential and commercial properties across every kind of environment, creating a protective perimeter that mitigates ignition risk from embers, radiant heat, and advancing flame.

"This isn't just an irrigation system. This is purpose-built fire defense."
