tjb1231-Boy, I wish you lived near me. I have a business doing what I described as "Household Handyman", I'm actually retired and need to stay busy so that's why I do this. Windows are one of my specialties, as no one else seems to like to do them. I have restored many windows in house's built prior to the 1950's, particularly in the early 1900's. Now, the answer to your question "Can these windows be saved?" YES! PERIOD! It's just how much time and monies you want to put into them. Based on the picture you posted with the rotten wood, it's just a case of determining where to start. First after taking many measurements-removing the glass. Determining what wood is rotted and needs to be replace is next. Don't expect to go to the big box store and buy this wood cut as needed either, all of it will probably have to be custom cut on site. I generally figure out the next piece, and make it before removing, as it usually is destroyed when removed. Provisions will have to be made to keep the window opening boarded up as the work goes on. I like to custom cut a piece of 1/2" plywood, paint it so that it doesn't look so bad and use screws as it will get taken down and put up many times. So-what are your skills, do you know someone with decent carpenter skills? Step back and look this one over really good and decide if you want to save these windows or pay to have them totally replaced? Good Luck, David
