How can I fix a window with cracked glass?
I had a similar problem.

It was easy enough to remove the window, and take it to my local glass shop.  They had a new pane put in by the next day.

If it's a screened window, you can do this when the weather is nice.  Otherwise, you'll need to cut a piece of plywood to block the hole while it's being repaired.

Taking it into the shop allows for considerable savings over having the truck come to you.

Call ahead and book a time.  You might have it done in a couple of hours.
