I bought my Simonton windows back in 2000 or so. About a year ago, one of the windows started looking weird and hazy. I tried cleaning it, but it was inside of the double pane. I guess it lost its vacuum.
These windows supposedly have a lifetime warranty, and I recently put it to the test. I called with the number off the inside of the pane, told them what I needed (got some more weather stripping for the bottoms as well as the sash), and about three weeks later I got a call that my stuff was in. That's not bad at all.
The place I thought I had originally bought the windows from is either gone or changed names, but Simonton/Norandex held up to their guarantee. It's one of the best things I've ever done to my house, and I've renewed that belief with the new sash/pane. read more
