OUR PROCESS
START WITH AN ASSESSMENT
1
1
ASSESSMENT
A customized assessment is the foundation of resilience. There is no one-size-fits-all approach — each property is evaluated based on its unique conditions and exposure. What the Assessment Includes: ◆ Evaluation of vegetation, slope, building materials, and site exposure ◆ On-site inspection guided by IBHS and CEA standards ◆ Photo documentation with a prioritized action plan and clear next steps

ACTIONABLE ESTIMATE
The same team that identifies the risks also scopes and prices the upgrades—converting your assessment directly into an actionable estimate and eliminating handoffs, delays, and back-and-forth for an efficient, stress-free path from assessment to implementation.

IMPLEMENTATION & DELIVERY
Your selected upgrades are completed with disciplined, code-aligned workmanship—translating assessment findings into durable wildfire and earthquake resilience through a smooth, predictable process. Every service includes clear before-and-after photos and a defined scope of work, giving you solid records for insurance, inspections, grants, HOAs, and real-estate needs.
