Over the years we have had all of our second story windows replaced and also had our kitchen window and side door replaced by Centennial. The workmanship is very good and the windows are high quality. I love that I can easily clean the windows and they still look good - some were replaced over 15 years ago.
Centennial did an excellent job fitting the windows to the frame. We own a home that is over a 100 years old and the windows had to be made to custom size.
The windows are well worth the money and I recommend Centennial to anyone looking for quality replacement windows.
