About Us
Three decades of California building
Alert One, Inc. DBA Golden State Contractors combines a B General Contractor license with a C-10 Electrical classification under one roof.
For more than 30 years, GSC has delivered design-build, commercial, electrical and public works projects across California. Today we bring that same experience home — helping homeowners add ADUs, rebuild after fire, remodel and build new.
Our team coordinates design, engineering, permitting and construction so you have one accountable partner from the first conversation to the final walkthrough.
