Three of my windows were getting streaked and foggy in between the glass. Since they were new when we moved into our house, the life-time warranty was still in effect. I contacted the manufacturer and sent them pictures of the three windows. They agreed to send me three replacement double glass panes, but I had to pay $40 each for shipping.
I sent them a check and a couple of weeks later three large cartons arrived on my doorstep. When I picked them up to take them inside, one of the boxes had a rattling sound inside. I knew that meant the window paned was broken. Examining the box, I could see there was a definite crease in the middle that looked like something heavy had dropped on it. I contacted the company again and explained the situation. They are going to send me a replacement.
