We spent a lot of time researching different brands of replacement windows and Marvin Infinity was by far the best and we are very happy with our new windows! Nex-Gen did a great job of keeping us informed during the order/build process; the installers were meticulous and were extremely knowledgeable and friendly.
They cleaned up the “mess” (created by the stucco exterior we have) both inside and out and even cleaned the windows for us. I would definitely recommend Nex-Gen and Marvin Windows!!!
