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.

Q: What are clients of Diamond Certified water treatment and service companies saying about companies in Duncans Mills, CA?

A: Verified Culligan Water of Sonoma County Customer, 1 of 618
"I've tried a lot of different options, but I think this is the best system that I could have ever purchased. If I ever leave this house, I'll have the same one installed by Culligan in my new place. It tastes wonderful. We aren't able to use it right now due to damage in our house, so we have been buying bottled water. The other day my son turned to me and said that the bottled stuff doesn't taste as good as Culligan's, and I agree. We are loyal Culligan fans." - Ella K.
