I'm changing out my aluminum single panned windows to vinyl, dual paned, Milgard Windows.
Will I have to be more alert to moisture problems, especially when we have the windows shut in the winter?
Also, what are your feelings on replacement vs. retrofit installation of windows? Replacement = removal of old window in its entirety (including frame). Retrofit = placing new window within old window's frame. What are the benefits/disadvantages of either?
