Cloudy, foggy, moisture in dual pane windows

You have probably seen this happen in dual pane windows. You may not even think it is a problem, except the window looks a little cloudy and hard to see through. It usually starts by looking like a dusty window that need to be cleaned. Over time, the window gets more and more foggy and harder to see outside clearly. Then one day you notice that the glass actually looks wet – it may even have droplets running down between the two panes of glass in the dual pane window.

We see it here in Placerville, down in Sacramento, and just about anywhere that there are dual pane windows installed. It actually is moisture that has accumulated inside the window. How does the water get inside the window? Glad you asked. As the window gets older the gasket can fail, allowing moisture to get inside. The windows now has lost its insulation value and condensation begins to form between the two pieces of glass.

There are several factors that can lead to the foggy, cloudy window gasket to fail. The primary reason is temperature changes, and that is usually a result of direct sunlight. Metal window frames can get extremely hot in the sun, then cool down at night. These temperature extremes causes cracks in the rubber window gaskets that hold the window in place.
Can the window panes be replaced without removing the entire window? Yes, and if the rest of the window is in good working order, this can be done at a reasonable cost. It’s a whole lot cheaper than replacing the entire window and frame and replaceing it with a new unit.
Good Luck in all your window projects.

  1. Rescue tape on

    Hey guyz, nice blog here. I use rescue tape for most of my repairs. It’s nice, you should try it!

      I have never used Rescue Tape, but it sounds pretty incredible. I didn’t see dual pane windows as a suggested use – that’s is the post topic.
