    Andersen was complete in their explanation of the process. I was fully prepared for the installation and was really surprised how efficient the entire project was.

    I was especially pleased(and sold on the products) by the full guarantee that if the windows leaked they would be replaced. The original installation of the Andersen windows and sliding doors on our home suffered leaks, and i did not want to see that happen again. So the guarantee was very important to me.

    Unhappy with the billing process. Received one statement before windows were placed and then another. Very confusing. I suggest one statement sent out.

    We were completely satisfied with all phases of our Renewal. Stephen,Zito, and the sales Rep were exceptional. He checked the job before, during, and after the job. The installers were clean, knowledgeable, and professional. We would recommend Andersen to everyone for their installations. Fantastic team.
