Since 2008, the Bay Area Branch of P.W. Stephens Environmental has been awarded the prestigious Diamond Certified symbol after being rated highest in quality in a customer satisfaction rating performed by American Ratings Corporation.


In order to earn Diamond Certified, a local service company must apply to be rated by American Ratings Corporation (ARC) and pass each step of its twelve-step rating and certification process.   ARC actually pulls a random sample of past customers from the applicant company’s files and surveys typically 100 customers by telephone.  Not only do the customers rate the applicant company on a 1 to 10 scale for quality, but also they indicate their willingness to return or refer other consumers to the company. Most companies can’t pass the rating because a customer satisfaction survey score of greater than 90 on a 100 scale is required.  In addition, ARC verifies liability and workers’ compensation insurance, state license status, complaint status, business practices, financial stability and legal judgment status. Additionally, ongoing customer satisfaction surveys are conducted to ensure the Diamond Certified Company is maintaining its high customer satisfaction.



“Our entire team at P.W. Stephens Environmental is pleased to earn this prestigious award.  And, it is especially gratifying because it’s based on our customers’ perception of our quality,”  - Scott Johnson, Owner


“Personally, I’ve been focused on rating local service companies for the past 15 years and I’m always impressed at how certain organizations are so focused on satisfying their customers. P.W. Stephens Environmental, Inc. is one of those special companies,” - Jim Stein, founder and CEO of American Ratings Corporation.

“I want to call your attention to the outstanding job done by your representatives with the asbestos removal work done at my home here in San Francisco.

First, your sales representative Mr. Jeffrey Hidalgo was most professional and responsive to my needs. He thoroughly evaluated the prospective work and gave me a clear explanation of the work and a fair market price. Whenever I raised a question or an issue he was very prompt and comprehensive with his answers.

On the day the work was to start, your team, led by Javier, was on time and clearly knew what to do. They were most efficient in doing the work of asbestos removal contracted for as well as the clean up afterwards. Javier and his team left the place spotless.

Although your team did not know this, I am the former mayor of San Francisco, and most familiar with contractors who work with and for a large city. Your team was among the best I have seen, and should be recognized for their contribution to the company by their superiors."

- Art Agno, Former Mayor of San Francisco
