Rachel asked:


I have double paned windows and there is white mold growing between the glass panes. Is this a health hazard?
I can’t scrub it out because it’s between the two panes of glass. I know the only way to get rid of it is to replace the windows, but I’m just wondering if it’s a health risk.

My windows on the southside of the house show moisture in between the glass panes. I have seen ads stating:
Don’t replace de-fog. Will this work satisfacturely? How is it done?

So we got this house and it has new windows, but we found out that they didn’t seal the top of the window all the way so now there is condensation between the glass panes now it is really blurry.

Here is a couple pics of the condensation.

The seals are not broken because we have had that checked. They said there we’re ways to get it out, but at that point my cell phone died and yeah….
