I live in the cold northeast, and am looking to replace 17 windows in my 60 year old house with energy efficient and easy to maintain / repair windows. This will be an expensive and messy project, impacting essentially every room in the house, so I want to do it right the first time and make the best choice I can for the window supplier.
I've been to see Pella, Andersen, Marvin as a first pass. I am especially interested in dealing with a company that will be around a long time, if there is any way to predict such things. My current 60 year old windows were made by a company which went out of business years ago, and parts have not been available for decades.
If ultra high efficiency has a good return on investment, and pays back fast, I will certainly consider the premium price as being worthwhile.
Many thanks for any thoughts or suggestions.
