Coronavirus Service Alert
Due to the “Shelter in Place Order” issued by Bay Area health officials, you may experience longer than expected response times from Diamond Certified companies. Thank you for your understanding. Stay strong and stay safe!
We’ve all felt the joy of choosing a good local company and, unfortunately, the pain when we mistakenly choose a bad one. The problem is, every company claims to be good, yet despite these glowing claims some provide inconsistent quality while others are downright unscrupulous.
The Diamond Certified Difference
We’ve solved this problem for you with the Diamond Certified Resource. Only local companies independently rated Highest in Quality and Helpful Expertise® earn Diamond Certified. Our rigorous rating and certification process starts with the in-depth pass/fail rating of each company’s customer satisfaction, license and insurances. Most companies can’t pass our rating and earn Diamond Certified, and every Diamond Certified company must continue to deliver on its promises to you, the consumer. That’s why we conduct ongoing customer satisfaction research and credential-based ratings and monitor each company’s performance.
We’re Here for You
Every Diamond Certified company is backed by our powerful Performance Guarantee, so you’ll feel confident in your choice when you use our always-free web resource or Diamond Certified Directory. If you try unsuccessfully to resolve a disagreement with a Diamond Certified company, our mediator will work with you and the company to attempt to reach an agreement that both parties can live with. If the mediation fails to produce a mutually agreeable solution due to failure of the Diamond Certified company to honor contractual obligations, uphold industry standards or participate in good faith, we will refund your purchase price up to $1,000.
Each time you visit diamondcertified.org, you’ll see each Diamond Certified company’s Deep Info, including researched company rating reports, verbatim survey responses, essential articles, photo galleries, videos and expert tips. We put all the information you need to choose a company in one place, and no other web page can match this depth of information.
Only the Best Pass the Test®
When you choose a Diamond Certified company, you’ll never be fooled by fake or cherry-picked reviews because we survey a large, random sample of each company’s customers by telephone (typically 100 surveys) to get the most accurate ratings and verify only real customers are responding. Company owners can’t cherry-pick by telling friends and selected customers to post 5-star reviews on our site—we don’t allow it.
So, if you want quality, you’ll have confidence in choosing a Diamond Certified company. We encourage you to visit this website on a regular basis to find updated ratings on top rated companies in your area, see verbatim survey responses on each Diamond Certified company, and read thousands of industry-specific expert articles and tips. We care about customer satisfaction, and we care about you. We’re proud to give you all the information you need to choose with confidence.

When it comes to remodeling a kitchen, budget is naturally a concern. Most homeowners want to invest in quality, but they also want to save money wherever they can. Read more
The service was excellent in-store and out. The quality of the dishwasher was very good, and they installed it. They were prompt, on time, and they did a very good job. The area where they worked was clean. I would absolutely recommend them.
The service and the people were very accommodating and knowledgeable. They took care of me.
Response to Diamond Certified Company Asien's Appliance, Inc.
They came out in the pouring rain to cover a leak in my roof and then replaced the whole thing as soon as the rain let up. I can't say enough good things about them. They are excellent. If you need a roof, call Joe Moore.
The expedience with which they showed up was great, but I really loved that Joe worked with me, because I couldn't really afford a new roof but needed to get one.

BENICIA — Following a hiatus from the construction industry, Billy Alcantara found himself drawn back into the field by an unexpected opportunity. “I’ve always been a hands-on type of person, so right out of high school I put on a toolbelt and got into construction,” he remembers. “My older cousin got me into the trade and showed me the ropes. A few years later, I left the construction field to work in sales, and after that I took a job in the manufacturing field.

Eventually, I knew I had to move on. Instead of going to work for another company and ending up in the same situation, I decided to get my contractor’s license and start my own attic cleaning business.”

BERKELEY — For Paul Cooper, a short-lived career in the solar industry led to a long-term livelihood as a plumber. “I got started in plumbing after the demise of the first wave of the solar energy industry that blossomed from the mid-70s to the early ’80s,” he recounts. “President Carter installed solar panels on the White House and the government created tax credits for homeowners who did the same to their homes.
