If I could give a 0, I would! I can’t even explain the headaches this company caused on me and my family. It took him and his “crew” 6 months to do a 2-3 month project. If you need a contractor you can talk with, Hector is NOT your guy. You may get a hold of him after the 50th time. You can call, and call, and call, but you probably won’t get a hold of him. During this 6 months, we had to talk to him about his employees drinking on the job, his men were drinking one day when we arrived on site. We told him this could never happen again because we as the land owners were liable for his employees. 3 months goes by, the drinking definitely dropped, but the lack of work did as well.Needless to say he was threaten to be fired several times, Wyoming contractor laws got in the way, until we were finally able to get him off our property. His work was subpar, to the point we had to hire other contractors. If you have to ask yourself, why did we keep him after all these issues…study Wyoming contractor rights. Less

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. Less

I would give 0 stars if that was an option. I have called this company three times and spoke with Hector each time about a drywall bid. Every time, he has apologized for not showing up and scheduled an appointment with me. Then he does not shown up or call. I do not believe this is even a legitimate business. Do not use them and beware! Less

Hector was extremely knowledgeable and helpful throughout my project, and he was especially skilled at working with my insurance company.

The crew that installed my new roof and gutters were also very talented and professional, and they paid close attention to every detail. Overall, I'm thrilled with the end result of the project.
