I have no qualms about the quality of windows at this point in time, though it's only been a week since the installation. It's hard to give full feedback when there hasn't been enough time to test them and see how they stand up to all climates and weather types. But the communication was really good, the price was decent, I never felt pressured and was allowed to come to my decision on my own terms, and all that stands out in my mind for being a good company, and based on that, I'd absolutely recommend Climate Guard for windows.
