I am looking to replace all of my builder grade windows after 20 years of living in my home. Since my wooden windows are deteriorating, I have been told that Vinyl or Fiberglass windows are the way to go. I live in Georgia and the front of my home faces East so you can just imagine how much sun damage these windows have incurred over the years. I had someone come out to give me an estimate on Simonton Generation windows. The one thing that concerned me is they only replace the window and not the whole frame. Once they replace the window, they put a formed piece of aluminum around the window that matches the trim. Wondering how that will hold up and look throughout the years. Any help will be greatly appreciated!
