I was replacing a 40-year-old large window in my home. I got competing bids, one was cheaper than EcoView, but I went with them because of the quality of windows (NT) and the professionalism of the salesman. I had some ideas about what I wanted without compromising the history or style of the house. The salesman gave me ideas, we chose color, style, and brand that was best for me (they offer multiple brands), and his expertise and recommendations were so valuable. No pressure, no hard sell. Awesome! The window looks great, it's crazy how much quieter it is and how much better the area heats and cools with a new quality window. It looks and feels like a whole new space. Well worth the investment, and probably paid for itself in better air/noise retention.
