We have two options: (1) Use the same windows as in the house, or (2) Try a different type in the garage. Out of sheer laziness, I decided to go with the same ones we have in the house. So, we went back to Renewal By Anderson and told them what we wanted. They sent a salesman out March 27 to draw up the contract. $2157 for the one window. April 6 another person comes out to measure the window so that it could be ordered.
May 4 they came out to install it. Took about two hours.
The next day someone else came and did the exterior mortar work to finish the installation.
I have trim pieces in the attic that match the window sills and trim from the rest of the house, and we used those. After everything was dry and stable, I sanded the new sill and trim on the inside, and put two coats of polyurethane on it.
