I got a number of prices and global was by far the cheapest but also one of the ones who had the best reputation. There was one project manager that I dealt with all the time, he was very responsive, he gave me his cell phone number, he called me with frequent updates, the project moved along very smoothly. The installers had a great work ethic, they were very conscientious to make sure everything was picked up. Global was responsive to all our needs before the sale, during the work, and afterward. We have referred Global to a number of friends who have all been happy.
