Help your favorite local business!
Elevate your company for quality customers.
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.

After being hit particularly hard during the COVID-19 pandemic, California seems due for a summer reprieve. Unfortunately, this is unlikely to be the case. Not only are many areas of the state seeing a resurgence of novel Coronavirus cases, we now face another, more familiar yet equally concerning issue: wildfire season. Each summer, wildfires destroy thousands of acres and homes throughout California, and this year looks to be no exception. That’s why residents (particularly those situated in the wildland-urban interface) must be vigilant about maintaining fire-safe conditions on their properties. Consider the following advice for defending your home against wildfires. Read more

They are very professional and responsive.
They get the job done in a short amount of time, they are clean, their clean-up is very good, and they are efficient.
I think they're very good at what they do and very helpful. Occasionally, something would get messed up, but they're really very good. I really trust them, and that's the important thing. They really try and work things out with you. I trust them to be honest and fair in their pricing. They're just really nice people, and overall, they do a good job.
Just how personable it is, it's like a family-run business. I feel like they're not going to screw me over. If they feel a part is too expensive for my car, because of how old it is, they'll try and find a quality used or discount part. They're always evaluating what will work out best. They have the expertise and the trustworthiness. They're very nice people, and that is a really winning combination.
