    Victor Anger was wonderful in his presentation and sale of the windows. He was genuinely concerned about our satisfaction and took time to carefully explain all the little details. Keith and the rest of the install crew were friendly and professional. Our install was done on a cold day in February. The guys used "zip walls" to keep the house protected from the coldness. We were home during the install and couldn't believe how quiet it went; no banging or other noise heard. We started with having seven windows installed and just ordered four more!! We were worried about not having natural wood on the interior but Andersen was able to offer choices of interior wood. We love them. There needed to be a slight adjustment done after the install. Andersen was very responsive and sent someone out within a couple of days. Great staff and great product!

    Everyone was very professional. The installers did a great job and we could for the most part have a normal day despite all the work going on.
