In replacing the windows I wanted them to be more correct for the period of the house compared to what is there now, and old pictures of the house show that it originally had 9 over 6 panes per window on the first floor and 6 over 6 panes per window on the second floor. There are 6 windows on the first floor, 9 on the second floor, along with 4 small attic windows. Anyway, when the contractor got back to me with just the price of the windows from the supplier, he said they were $11,500. That is before the labor that will be required to remove the old frames and replace them. I'm guessing that when the labor is added, the job will be a minimum of $15,000 but probably higher. Does this sound reasonable (windows quoted were from Marvin)? These windows quoted were wood windows with wood divides for the panes on both the inside and outside. Are there alternatives that would be less expensive but still look decent on an older house?
