    Great job! Exceeded our expectations. We would definitely call again if we need any other windows or doors replaced. Very professional and very skilled installation team.

    Very professional from start to finish. Once we decided on a window, the sales team had a contract ready, and gave us an installation date/time. The day before installation, we received a reminder call. The installation team arrived right on schedule, and did an excellent job. We are very satisfied with the result. There were no surprises - everything turned out exactly as promised.

    Before the installation, I was told that the windows would be open to the outdoors for only about 5 minutes so that minimal heat would escape for the house - important for a winter installation. In fact, the windows were open for an hour or two. The installers told me that it is not always possible to have only a 5-minute interval between taking out the old windows and putting in the new ones because of necessary adjustments to the frames. The window consultant/sales representative should have acknowledged this fact.

    Love our new Windows. We are happy with the dramatic difference they make in the home! The consult was fast and friendly. Our window measurement was thorough. The installation was not intrusive, quick and well planned. The house didn't feel like it was under construction at all! Even our cats were at ease. We would recommend Andersen to anyone!
