Lifetime windows have installed 9 windows for me on two different occasions. They are wonderful from the beginning to the end. I have had a few problems, which were how I was closing the windows, but they are so nice and helpful. I highly recommend Lifetime Windows for everyone. Thank you for being there for me. My windows look fantastic.
