Well, the 100 year old windows with the wavey glass are gone...so sad, NOT REALLY! Since we moved into this fixer-upper, one of the top things on my wish list was to get new windows. It took the glass guys 2 and a half days to replace all 29 windows. I can feel the difference inside already! It's much more quiet (we don't hear the cars drive by) and I don't feel a breeze blowing through my house.
