Over the past couple of weeks I have interviewed Lowe's who recommends their Atrium windows, Home Depot who recommends either their American Craftsman or Simonton windows, and Sears who is priced way out of the ballpark for me. Then there is Windows R US that is recommending their NT Window which is triple coated with an insulated frame. I have a 37 year old brick home in East Texas with the original aluminum frame single pane windows that need to be replaced. I listen to the everyone's pitch, they leave & I do my homework. The Atrium & the American Craftsman scare me when I read reviews. The Simonton has an excellent rating from JD Power & Associates & good reviews, but they are pricey. I can't find enough on NT Windows to be of any good in my research. I have an appt. today with Window World & tomorrow with Champion. After 2 weeks, I am no closer to making a decision now than I was then. I need unbiased opinions on a good window that will fit in my budget from someone that is not trying to sale me something. By profession I am in ministry work. I work for a non-profit ministry & do not make a lot of money, so it is important that I get this right the 1st time. I need to replace the windows to reduce my energy bills, making the home more affordable for me. Any advice or help from professionals will be much appreciated.
