New house, it’s Edwardian with all its originals features including the windows all downstairs. Single panes though and we are feeling the cold when the heating isn’t blasting. I really don’t want to lose the windows, I would hate to change them to plastic. Is it going to cost an absolute bomb to get new wooden frames and double glaze ? We had a quote to encapsulate the stained glass and it was 12k 😳😳😳
