I have a 1962 Brick Ranch home in SE Virgina with single pane double hung windows. I would like to replace them with something that is more energy efficient, and works better at noise reduction and eliminating cold drafts. I want to do all the work myself, but I am looking for manufacturer reccomendations. I do not want to spend $500 per window. Basically, I am looking for something with very low maintenance (no painting) and that is energy efficient. Please list any recomendations for manufactures that provide good quality at modest prices that I can buy myself and do my own installation. I am leaning toward replacement windows vs New Windows as I would like to keep my existing molding and trim.
