    The men that installed the windows were amazing and did such a great job. however the consultant that came to our house initially is not professional and rude. i had a few questions and he snapped at me and was disrespectful. He took way to long and was long winded. i was not happy with him and neither was my husband. we purchased your product only because of the reputation and the need for great windows and not based on your salesman who sold them to us. i would use your company again but not the salesman.

    The price was so much higher than I'd expected!!! " Buy one window & get the 2nd window at 50% off", was not honored nor was a code given to me accepted. I went ahead with two windows anyway because of the ANDERSEN "name" but I do not see the label on the windows themselves, I feel cheated .

    I am extremely satisfied with my windows. We could feel the difference in the house. It's great. The men were courteous, clean, polite. Thanks for all your help.

    We are very satisfied with the installation work. Manny did an excellent job putting up the bay window. Everyone of the four crew members was professional and friendly. The windows look beautiful. The only possible problem we found is the moisture inside on the window glasses when it was cold outside. We will check it next winter.
