I had an excellent experience with Gregco, thanks to Hector, the project manager. Hector was extremely knowledgeable and helpful throughout my project, and he was especially skilled at working with my insurance company.

Grego built our new bank branch in Rock Springs three years ago. He did a great job. The building is beautiful and functions well. I am happy with his work and would use his services again.

I hired Gregco to do my driveway and they did an awesome job. When I found out they also do roof repair and house painting, I asked them for a quote. I wanted to change the color of my house from yellow to greige. They gave me a fair price and a realistic timeline.
