Replacement Windows

[lobo11]

I am looking at replacing windows before winter. I am getting estimates from three businesses. Together they carry the following brands:
1. Alside
2. CertainTeed
3. Kolbe & Kolbe
4. Integrity
5. Simonton
6. Renewal by Anderson

My dad has new Integrity windows, and I really like them so I have one starting point. Any info. on any of the above windows that you guys have experience with would be appreciated. Thanks.

This thread covered a lot of good points.

My father-in-law intalls windows for a living, and loves Paradigm. The install workmanship is, naturally, as important as the window construction itself. Availability is a function of the jobbers in your area...

But then I also figure they're like radial tires, any modern window is better than a 1950s single pane...
