I have employed GSI contractors for several projects that range from commercial construction to renovation of investment properties as well as a couple of personal projects for my home. The scale of the project seemed to be irrelevant to the GSI crew as they devoted the same attention to detail on every project. In every case GSI has displayed an admirable work ethic and mastery of their craft. I have come to rely on the expertise and recommendations of GSIs skillful contractors as their input has saved time and money on every project and they have been able to deliver a quality result at the same time. Thanks for a job well done!
