Bill quickly discovered that the new doors were a bit too short for the doorway.
That made for a nice big gap.
So, Bill found a scrap of chestnut from the wood pile in the basement, and he filled in the gap at the top. Now, that piece, along with some other spots, will need to be cleaned, very lightly sanded, stained, and given a tough finish coat.
Even though the new door has much more glass than the old door, I can already tell that it blocks much more sound, because it fits the space better. I expect it will do the same at blocking air-flow. Bye-bye cold drafts this winter. Well, from that spot, anyway.
