George was very honest in what services he can provide, if he felt the project was out of his scope he kept it honest and give alternatives for the project.Mounting my television was one of the projects George did, After coming out and realized my stone was placed with nail glue, George suggested mounting from the ceiling to get the look and better stability I wanted and that was the best. Thanks George I love it

George and his crew were very professional, honest, patient, I had many questions and they listened and answered all of them. George went above and beyond to make sure that I was happy with the new system. He communicated well via text and emails. It was very easy to work with them. I will hire them again and I highly recommend them.
