House is 7 years old.

The warranty only covers the windows if you are the original owner. I have to replace the windows myself and the shipping for each window is $25. I can do this BUT I am the 2nd owner. Too bad for me. The cost would be substantially higher. From what I have read on the internet lately, I should expect more. So why buy their windows to have them fail AGAIN? I would need a subsription from MI Windows and Doors.

I was a builder 5 years ago. I have NEVER seen a failure rate so high in a window.
Most good manufacturers have a warranty and many have a 10-20 year warranty. But I have never seen such a high failure rate. I contacted MI Windows about it. They said this is normal.
I have been out of the construction business for a while. Companies are bought and sold like baseball cards use to be. Any suggestions on brands of replacement windows that are of better quailty? Looking for gas filled, vinyl, double glazed, single hung.
Thanks
