WHY CHOOSE A DIAMOND CERTIFIED COMPANY?
Watch this video on the Diamond Certified Resource: the most accurate and trustworthy way to find local companies rated Highest in Quality and Helpful Expertise®.
Shares

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.

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.

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.

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.

David Tetrault: A Northwest Progression

By James Florence, Diamond Certified Resource Reporter

SAN MATEO — For David Tetrault, a westward relocation precipitated a northward advancement in his professional career. “I’m originally from Massachusetts, where I got my start in the construction industry,” he says. “In the mid-2000s, I decided to pack up my tools and move to California.

Jorge Paiva: A Service Calling

By James Florence, Diamond Certified Resource Reporter

MORGAN HILL — After requesting a service call to fix a broken appliance, Jorge Paiva ended up getting a lot more than he bargained for. “My apartment had a broken dishwasher, so a technician was sent out to fix it,” he remembers. “We got to talking and he told me the company he worked for was hiring.
