Diamond Certified Resource Compared to Crowd-Sourced Review Sites

Diamond Certified Resource’s ratings of local companies are based on surveys of only verified real customers, so they are the most accurate. This beats crowd-sourced review sites like Yelp, Angi or even Google that are plagued with fake, manipulated, cherry-picked and non-customer reviews, which produce inaccurate and often inflated rating scores.

Diamond Certified Resource’s deeply researched reports of top rated Diamond Certified companies include everything you need to see to be very confident in choosing a top rated local company. Each company report includes detailed quality ratings and scoring, verbatim customer survey responses, a profile video, a company story video, a capabilities table, a photo gallery, researched articles, unique expert contributions from the company’s owner, and more. This beats crowd-sourced review sites that solicit companies to “claim their business listing” and add any type of info to their profiles. This sounds good, but it has led to company profiles that are littered with false claims and incomplete info.

Verified B. Henry's Quality Electric Inc. Customer, 1 of 852
"We love him. He did not charge us. He came out two times, because one of our trees fell on a gazeebo and knocked off the cover and the electrical to our pump. The insurance recommended him. He came out and told us that he could fix it in a minute. He fixed it and didn't charge us. What a refreshing person. We were impressed with his expertise and communication. The next time he came out, we called him privately and asked him to address another issue with our pump. He told us that we didn't need him and that it would be a waste of our money. We needed to contact the pump company and he told us that they should have their own people who could come out, fix it, and that they shouldn't charge us. The next time we used him, we bought a home that had some serious electrical challenges. I have several friends who are general contractors, and they wouldn't touch it and said that we would need a really good electrician, as it was really complicated. Bill came out with his son, told us the price, told us what he would be doing and how long it would take. Everything was identical to what he told us. He's just phenomenal, and I would recommend him to anybody. His incredible honesty and his astounding knowledgeable of the subject matter, also, if he tells you that he will be there at 9:00 AM, he is there at 9:00 AM. His son was also very impressive and looks to be a chip off the old block. He's very copasetic with his father's though process." - Gary A.
