I'm picky. I have seen windows from multiple manufacturers. Infinite wasn't the cheapest quote (not the most expensive either). John showed us a couple working samples from VinylMax. When I was shown the Sherwood, I was sold. It is absolutely a beautiful window. Their installers showed up at 7 a.m. sharp just as I was told, and they were great! You can tell that they know what they are doing. I would recommend this company to anyone. Now that it is hot, I can really feel the difference in my house, especially the living room!
