I have a large (96x48) casement picture casement window in my kitchen. The casements are getting condensation and on one of them the exterior pane is broken. I priced some cheaper vinyl windows and it was going to cost me $800 for a new window. Any ideas what it might cost to replace the glass instead? I'm leaning towards replacing the whole window because we will be putting in a new casement in another area of the kitchen, but $800 seemed hefty for a window in a starter home.
