Diamond Certified Resource’s ratings of local companies are based on surveys of only verified real customers, so they are the most accurate.

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.

A: Verified Thompson Construction, Inc. Customer, 1 of 47
"He appears to be quite honest, and he was willing to take on some small, odd work that we had to do. I appreciated that, because sometimes the contractors will blow you off when you have that kind of work. The fact that he answered the call promptly and came over, we needed to get something done quickly, and he managed to squeeze it in between other work and still get it done. The guys he had doing the work were quite competent." - George D.
