Monday, May 5. Window.
Installing the window was easy. First step: staple up some flashing. Second: caulk. I forgot this step.
Third: nail the window in place, through the handy holes in the nailing fin.
Fourth: Caulk some more.
Fifth: put flashing across the header. Voila, a window.
There was plenty of flashing left over.
What the heck, while the caulk was out, I sealed one of the edges where the foundation touched the concrete. Did a messy job of it. Good thing it was along the back side.
