    Item 2: We have talked to several neighbors who saw our new windows. One is considering a change in her own home; she is waiting until fall due to finances. Item 8: A few pesky pieces of trash escaped the examining eyes of your staff. Easy for us to deal with, so we were fine. Thanks for the great job!

    Anderson has an excellent product and good service. My only issue was there were large pieces of glass shards remaining in the landscaping and we are still picking them up as we see them. I mentioned it to the rep but he overlooked it. The guys installing were very pleasant and professional and I was comfortable having them in the house all day.

    I am very satisfied with my new ideas for your windows. I look forward to many years of enjoying them. Your improvement and the quality has gone up extremely positive. I did have your windows years ago. I hope I will continually enjoy my doors and windows each and everyday.
