Dear John,
Last week, Tri-State Window Factory installed windows in my home, and I am very happy I chose them to do the job. Before I contracted with Tri-State, I had gotten estimates from seven other companies, and saw the windows they were going to install. In my estimation, none of these companies had a window that compared to Tri-State and their prices in most cases were higher than Tri-State. From speaking with your sales people to doing the actual job, your people were the best. Installing 30 windows in my home, I don’t think was a small job. Your guys did it in one day and they did it right. I would recommend Tri-State to anyone.
Thanks for a job well done,

George M.
