I was so pleased from the time i opened the door and in walked Oliver. What a refreshing change from any other quote I have gotten. Professional, personable and super friendly. After 10 minutes of listening to him i was sold. Then I got the windows done and am even more pleased then ever. They are fantastic, Oliver suggestions were dead on. He suggested i have the 2 small windows put at the top instead of the traditional bottom, he was right again. Once they were installed i was having trouble with the patio door, i called Oliver and he came right over that evening and showed me what was wrong, turned out it was the operator. Not once did he me feel bad for calling him, he was so professional and took the time to explain everything to me. The installers were very very efficient and did an amazing job. My only regret it I did not go with them for the bedroom windows, went on a recommendation and was not nearly as satisfied as i was with Oliver's service.
