Customer satisfaction

From beginning to end, my experience with Asher was exceptional. Calls were courteous, response time was quick and the personnel were kind and understanding. The ordering process was easy. Although the wait time was longer than expected, I think that it was due to circumstances out of Asher’s control, and they let me know well in advance that there would be a shift in timeframe. Kolton and Hunter, the installation team, were on time. They provided dropcloth protection of floors throughout the house. After detailed clean-up, Kolton gave me an introduction to my new windows and how they work. They were both personable, professional and friendly. Their work is crisp and clean. I will order from Asher again.
