Mr. Kim was amazing throughout the whole process! He was fast, efficient, but also very meticulous about his work. I love my windows! Windows on Washington came earlier than I expected and was so pleased to have them do the work a day after Christmas. That is true dedication! Mr. Kim's attention to detail and meticulousness really made this experience great. I also appreciated Jay's openness and honesty and how he didn't try to strong arm me into a sale or treat me like I was ignorant like many other companies do if you are female.
