Edgerton: Old wood-sill windows out (they were quite useless), and new double pane, vinyl windows installed ($105 @ Menards).  In the process, I replaced the window jams with new 2×8 treated lumber, since the old ones were rotten.  Notice, the mortar on the bottom sill is slightly pitched to run off any water.

You’d be amazed at how much light is now able to enter this basement!
