The installers were professional, polite, and industrious. I was amazed at how quickly the windows and doors were installed, and I loved the color options for the internal window frames. They match our woodwork beautifully. The 90 year old windows they replaced had some interesting pulley hardware that I remarked upon. When the installation was complete, one of the installers brought me a number of the pulleys and asked if I wanted to keep some. It's cool to have some of the history of the windows from this old house.
