The installation guys that they have are great. Notification-wise that they have is okay. It is kind of in the air. For example, once you set your order, they don't really let you know until a week before. You would think they would send you updates here and there while the windows are being made to see what your timeline is. Other than that, I would say they are good.
Window World did a good job and cleaned up after themselves.
Quality product, good customer service, entire process is easy
