If it has been me, I would have replaced the whole window with a whole new one. Gone to Home Depot, bought a custom size window and had it installed. Probably a couple hundred to cover the costs at least.
Brad figured if he did it himself, it would be cheaper. He took the window apart (it's a single pane window), ordered a plate of glass from Speedy auto glass ($66) and rebuilt it himself. Added the window trim and BOOM. Done. I have to admit I was pretty impressed.
He had a pretty big swagger when he came back in the house and justifiably so. That took mad skills!
It should be noted that the to do list I have been using is actually only from the Spring. The list was WAY longer in the fall of last year. It was as follows, drum roll please
