Four Bay Area Companies Earn Diamond Certified Status

The newly recognized businesses are Brownstein Construction Inc., Chase Electric, Finest Precision Setters Inc., and Valdivia Roofing. To qualify, these companies had to score 90 or higher on a 100-point scale, a threshold that excludes firms unable to meet the organization’s strict performance standards. The evaluation methodology includes verifying state licenses, insurance coverage, and business practices, alongside confidential feedback from verified clients.

Greg Louie, CEO of American Ratings Corporation, noted that the certification remains a significant hurdle for most applicants. Beyond the initial rating, these companies commit to the Diamond Certified Customer Satisfaction Principles, which include participating in mediation if service disputes arise. The award also provides consumers with a performance guarantee, ensuring continued accountability after the initial certification phase is complete.
