Renewal by Andersen Windows
I just replaced 16 Andersen windows..in the summer ..was fine. Until last 2 weeks, with changing weather in Michigan, from warm day to cool night plus 60% humidity. My EXTERIOR window just built up with moisture on the outside ..to a point you can't see ...I have never had any problems with this issue before ..even with my old windows which I still have some on my house, they don't have this issue.. Does any body know what's wrong with the windows? Help!! Thank you in advance.
