Testimonials

Dear Tri-State: This is not a letter of complaint, rather a letter to tell you the excellent service I received from this company and excellent product they provided in 1997. I requested a report from your office on this company and from that good report we hired them to install their windows. We were very “Louise C”

Dear Paul: I want to apologize for sending you this letter so late after your company installed the windows on our property. My schedule became very hectic with the planning of the camp season. However, I still wanted to send a short note thanking you and your entire staff for such an outstanding job. First “Brian M – Glen Cove”

Dear Tri-State: We are writing to inform you of the great job that Mike Hirakis and his employee have done for us. We were very satisfied with the work. He made sure to do things the way we liked it, and consulted with us throughout the entire time they were doing the work. The work “Anthony & Damary P”

Dear Tri-State: Although I am not much of a writer I just had to let you know how pleased we are with our new windows. They were installed at the end of January and with all the crazy weather we have gone though in the last few weeks they have already gotten quite a test, “Liz & Adrian”

Dear Tri-State: Last week we had a problem with one of the windows your company installed several years ago. While trying to clean it one of the sashes fell out and we had trouble replacing it. We called your service department and explained the problem to them and requested that someone make a service call “Tom M”

Dear Tri-State: We love our new windows. With the extreme cold this week, it was easy to tell that the house was much warmer. Additionally, you promised us that we would have the best installers, well you were correct again. Not only were they fast and precise, but they left our home just as clean “Lois & John – Nesconset”

Dear Mr. Presley On April 28th we placed an order with you to install all new windows in our house. You promised delivery by the first week of June and installation to be completed in one or two days. A word of thanks to you and your installtion crew. All promises were kept on time, “Steve”

Dear Bryan Egan, Tuesday, the 24th of June, we had the 6 windows put in. I have to tell you George was so neat and jokes with me all day. I could not believe his work. I said to him, you are by yourself? He replies, you will be very satisfied by the end of “P.M.”

Dear Customer Service, Thank you so much for the wonderful service that has been provided, and all the personnel and staff that made this possible. Thank you. Sincerely  

Dear Tri-State: I just wanted to take the time to thank you and your team for the wonderful experience I had with all 34 of our windows! I own a Marketing Firm and each day we need to exceed client expectations. I personally can appreciate the challenges of being in a services oriented company. From “Adam – NY”

Dear Tri-State: Just a note to let you know how pleased my wife and I were with the job you did for us. The installers, Murry, Ben and Pete, were professional and neat and did a great job even with the errors made by the original siding contractor. I felt an improvement in the heat “George & Karen – Bohemia”
