I wanted to contemplate on this issue since many of my neighbors have or are considering replacing the original windows in thier homes.
History: My neighbohrood is comprised of colonial style homes built by Richmond American in 1987. the windows used were double-hung dual pane wood frame windows with full length screens.
Here is an itemized list of what I would have to replace:
- 9 36″X72″
- 3 27″X72″
- 2 24″X72″
- 9 36″X60″
- 2 24″X60″
- 3 27″X54″
- 2 22″X32″ (casements)
That's a total of 30 windows folks and 14 of them are considered oversized therefore requiring tempered glass per local codes. I had a few estimate done when In early 2006 right after I moved in. The list prices ran betwen $21,000-41,000 depending on the quality of windows. My average gas and electricity bills together run between 175-350 epending on the season and tempature extremes. So if I am promised a 30% reduction in those that would save me at most 100 per month. At that rate the windows would pay for themselves in...

My overall opinion is that buying new windows just for hte promise of energy savings is probably not going to pay off. If you windows are very drafty or do not close well or if they are deteriorating at a rapid pace those are valid reason to investigate replacement windows. With any estimate calculate the time it will take to recoup the cost of the windows with the energy savings.
I personaly took the route of having a company come out and copletely remove and replace the original metal "guts" with new plastic ones. then they reinstalled all of hte windows adjusting them so they would close completely. This was done including fixing a wapred frame on one of the windows for under $3000.
I know I will get flack about this since window replacement was and is a big thing right now. However, I believe in working with a home's existing features whenever possible and that not all capital improvement to a home pay off as advertised.
