I've been thinking about replacing the windows in my house and wanted to get some insights from you guys. How much are replacement windows nowadays? I've got an old house with drafty windows, and it's time to upgrade. I'm not looking for anything too fancy, just something that will improve energy efficiency and boost the overall look of the place.

For those who have gone through this, what should I expect in terms of cost? Did you go DIY or hire a professional? Any brands or types you'd recommend? Appreciate any tips or advice from your experiences. Thanks!
