The installers arrived early in the morning, did another measurement and then began the work.
I was introduced to them and I pretty well stayed out of their way while they removed the old door and installed the new one. They suggested a new doorbell switch and it made sense for me to get a new one. Why have an old piece attached to a new door. It took them just over 3 hours to complete the work which was shorter than the estimated 5 hours. Over all I am very pleased that my wife is happy. She never liked the original door when we bought the house 25+ years ago.
