The new front door is installed! This is a huge improvement over the old door that was drafty, sagging, and never opened when the weather was humid.
It took years of planning and research. I really wanted a double door, but finally had to admit it wouldn't work, the space was too small.
This door is a generous consolation prize. In addition to being 2 inches thick, it's 42 inches wide and almost 8 feet tall. So instead of 2 small doors, I have one massive door!
In the end, I'm very happy with it. Just waiting for a nice big knocker (go ahead and giggle)!
