repairing aluminum windows
Hi all! I'm new to the window forum. We need to replace/repair our 25 yr old double pane bronze aluminum windows. My brain is in vinyl window overload. We have been quoted a price of $280 (uninstalled) each for Viewpoint series 6000 & $483 (uninstalled) each for Simonton Prism Platinum. Both windows are double hung. What are your thoughts on these 2 windows? From everything I read, in 20-25 years we may be having to replace windows again. Someone told us there is a process of defogging & resealing aluminum windows at $100 each window. Does anyone have any input about this? Thanks for any help you can provide!!
