I live in a 1960 Burnt Adobe (brick) home and would like to make it more energy efficient by upgrading the windows. I even purchased the Home Depot's Do-It-Yourself book, but they only talk about replacing windows w/ wooden sills. Is this a project better left to the professionals or is there still hope for a novice like myself. I'd need step-by-step guidance. Is there anyplace to find this sort of help?
