Recent Review: I found this company through Angie's list and look at other sites as well. My search started out as a mistake in terms of my search as I am in Athens and they were serving Atlanta. Initially I thought I was contacting an Athens, GA vendor. However, I called and their marketing exec came out, measured and gave me an estimate. I interviewed 4 other vendors. Greenview price was better than any one else especially given the quality of the window. Installation took two days. They were incredibly efficient and cleanup the area well. Everyone was friendly and professional from Marketing Manager, to the service/production manager, to the service desk. I wanted to wait a few months before I gave my review. Everything is still good, looks good and we feel no air sneaking through on windy days. It is also much quieter. I would recommend them again and agree with all other A+ reviews I have read on Angies list for them.
