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.

Wayne originally came out, looked at the job, and about a week later the crew came out. " - Elijah L.

"They are thoughtful, respectful and communicative. They are not just looking at the job. They will go beyond that and they will make recommendations and suggestions. To sum it up, they think like a homeowner and they see it through the homeowner's eyes. They take a very forensic look and a very thoughtful look at the whole picture. It feels like they are doing it as a friend. They are collaborative and they treat it like it is their own home. I would empty my bank account to have them come out to my house. They have compassion and care and you don't get that any more these days. It feels like a friend who is an expert in their field. They will not steer you the wrong way and they are not in it for their gain. They will do quality work and their focus is quality work and making their clients happy. When I pointed out something small that needed to be fixed, they went above and beyond to make me happy without question. They just get it and they understand what it is to do business well. I can't say enough about them. I can't stop. They take as much pride in their business and their clients as I do. Their sense of pride and respect is bar none and that is what I expect. I have a very good relationship with every person I touched and they were all respectful and courteous. I dragged them through maybe 8 estimates, as I had multiple floods with the storms and they were patient. They understood. They were human and compassionate. They get it." - Diane S.

"I felt Lance was extremely experienced and explained the process. The job needed to be secure for our bank after a huge slide. He was very knowledgeable and easy to work with. His team that we used also provided us with survey, drilling, etc. I have given his name to others that had a slide and erosion like we did. His honesty in a difficult situation, Lance was here every day of the job, so we didn't have to worry about workmanship." - John B.
