"The whole process from start to finish was easy and painless. Scott was very responsive and answered all of our questions and concerns. We sat through two other windows consultation, and they were both hard sales pitches. I like Zen Windows' business model. We went with Zen Windows because of their warranty, price, and their great reviews. His crew did a great job during installation as well. We had old metal frame windows along with storm windows on the outside, so the job took a bit longer, but it was well worth it. We replaced it with their Lotus windows by Soft-Lite. We love our new windows. I would definitely recommend them and use them again in the future!"
