I have viewed and sold so many homes with dual pane windows that have failed. 
The clear, or should I say unclear, indication is fogged up glass. When you try to clean them, you quickly realize that there is moisture trapped in between the two panes, hence the window has failed. Most inspectors will tell you that this does not diminish the effectiveness of the window, rather it just looks ugly. And typically the remedy is replacing the glass or the 
window, which can be costly.
I ran across an article/ad regarding a newer technology, whereby they can de-moisturize and repair the window by just drilling to small holes in the corners. Sound great if it actually is legitimate.
Has anyone out there utilized this technology? And more importantly, does it work? If so, this would be a great innovation to all those failed windows out there.

I’ll be curious to hear if someone responds and has used the technology you referenced. I just know moisture really makes the windows look ugly. No bueno.

Yeah I googled the subject and there are some mixed reviews. Many that said, “Go by a new window!” without much explanation. And then there were others that have had great experiences.
