About us

My dad and I have always worked together in construction, inspiring me to put in more effort. When I received my California Commercial Building Inspector license in July 2022, I launched my business and pursued more certifications and licenses. I applied for the Reinforced Concrete license in October 2022, immediately after earning my license. As a result of receiving the American Concrete Institute Field Testing Technician license in November 2022, I am now pursuing the structural bolting special inspector and structural welding inspector licenses to expand my business and empower it to offer a greater variety of services.

Our clients say

I am incredibly grateful for your team's quick implementation and adaptability on location. Sierra's Deputy Inspections gained knowledge of our structure and procedures to provide us with effective, high-caliber services at a fair price.
Antoine
They always strictly follow my instructions, which are always entirely clear. Technical expertise is crucial since it allows one to understand standards, conduct appropriate testing, and take ownership of quality. Most importantly, though, they comply with client needs, communicate with us effectively, and answer queries after the service.
Ellen
