(December 31, 2021, 12:35 am)I had GSI complete some exterior work on my new home. They did concrete patio, garage floor, front entrance stone work and a small section on the side of interlock. They were very professional and easy to work with and George answered all our questions and gave great advice on the layout. We are very happy with the outcome and would recommend his work. Thanks for helping us out it was a great experience.
