What Causes Foggy Windows?

    I recently received an email from Mrs. Pearson who lives in Flower Mound, Texas. She had a very good question about a common problem and I thought that many of you may be experiencing the same problem and would benefit from this information so I’m writing this in response to her question.

    She wrote:

    “I’m writing you because you are the Dallas window replacement expert and I need your expert advice to solve a problem. We bought our home in 2015, the year it was built. It’s a nice home with plenty of space and a lot of windows we live in a great neighborhood with great neighbors. I’m having a problem with my windows several of them are cloudy or foggy with moisture in between the window panes. I’m unable to clean them because the problem is in between the two panes of glass. I spoke with one of my neighbors about it she told me they had the exact same problem with one of their windows so they had a company come out to replace the glass in that one window. I have several windows that are cloudy or foggy and I don’t want to put a band-aid on the problem I want a permanent fix. You’re the expert, what’s the cause of this problem and what should I do to solve it?”

    The problem you’re having is a common problem that is generally found in homes that are 5 years old and older. Your windows are double pane insulated glass which are two panes of glass that are separated by a spacer and sealed. The problem is the seal has failed to allow moisture and air to get in between the two panes of glass.

    Cheap is Costly

    This moisture and air causing condensation which causes the glass to become cloudy and/or foggy. Yes ma’am you’re right you can’t clean this from your windows because the problem is in between the two panes. You’re having this problem because of the builder-grade window installation in your new home.

    Builder-grade windows are cheap inferior windows that just meet the city codes and requirements to pass inspection – and that’s about it. On the bright side, builder-grade windows are as good as or even better than those inferior vinyl replacement windows that you can get real cheap from several local window companies.

    Your neighbor’s solution was right for them. I always tell people who have just one or two windows with a failed or broken seal to go that route if all they want is a quick cheap fix to their problem. It’s a misconception to believe you can completely upgrade your windows by just replacing the glass because you have to replace the entire window to achieve that.


    Here’s why; when you replace just the glass you can upgrade the glass itself with Lo-E and argon gas and with or without a grid pattern but you’re using the same cheap thin aluminum frame. Builder-grade aluminum windows aren’t thick well-built aluminum replacement windows with a thermal break to help prevent heat and cold transference into your home. So when you just replace the glass that’s all you’re getting is new glass.

    Since you have several windows that are cloudy and/or foggy with condensation forming between the panes I recommend replacing all of your windows with premium vinyl frame Energy Star rated energy efficient windows this way you’ll be able to reap all the benefits that go along with them.

    Some of the benefits of purchasing your energy efficient windows from Inside Out Home Improvement are; lifetime warranty, glass breakage warranty depending on the manufacture and the windows you choose.
