The original work was good bad then they owner and I communicated multiple times via text and he told me he will come and fix the problems with the concrete on my driveway, but he never did. He has been over 6 months since he told me he will come to fix my driveway. I am in the process of reporting him to the BBB and Jeffco and the association of contractors to see if they can suspend his license until he finishes the work that was not done correctly. I hope you are getting this message Humberto because people like you should not be in business.
