Guess I'll have to take a beating here ...
Last year I broke one of my 15 y/o Anderson Windows with a rock thrown from the mower .
Couldn't get a replacement in what I considered a reasonable time frame , so I called window world , yea I see you rolling your eyes.
Salesman came out and showed me everything about the window .
I ended up changing 6 Windows on that side of the house so everything matched . Hard to believe but 6 Windows installed ended up only costing about double what just 1 Anderson would have cost me .
Now are they as good as a brand new Anderson, I doubt it . But they are a heck of a lot better then a 15 y/o Anderson .
Both my heating and cooling bills went down a tiny bit even as my electric rates went up .
And I'm happy enough with them that this spring I'm going to replace the rest of my Windows .
I might feel different about this choice if I had a bigger / fancier house that this might affect its overall worth .
But I don't , I have a 1250 sf ranch , new Windows of any type will only increase its worth .
