Outstanding service, product, and best of all communication throughout the entire process. I got about 6-7 quotes and chose Kepo just because of the professionalism of my rep Ron, as well as the office staff and installers. They banged out 27 windows in about 2-3 days. High recommended and I’d use them for things other than windows now that I know they are top notch. Went with the Anderson 400 series – no complaints and I’m already feeling some energy efficiency. The windows really changed the entire look of my house as I went from white to black windows. Keep it up Kepo team!
