We all know that condensation between the panes of glass on our windows is a bad sign.    We also all know that brand new windows will reduce drafts, making out home more energy efficient and keeping us more comfortable.

So then why do we sometimes see more condensation on the inside of our windows after they've been replaced?

Easy.   They are working.

Energy efficient windows might fog up if your humidity is high.

Before when you had those old drafty windows the normal moisture in your home  (from showering, cooking, breathing, etc)  could escape right outside.   Your new, custom sized energy efficient windows are just keeping everything inside.  They are blocking air movement between the inside and outside of your home.  This is good.   They are also lowering your heating and cooling costs,  and keeping you more comfortable in your home.

More importantly, as the temperatures outside get colder and the humidity inside your home increases, you might notice more condensation building up on your windows.    Obviously we can't control the outside temperatures but we can control the humidity levels in our homes.   So if you have some indoor condensation or you want to make sure you don't get any, keep reading.

5 Tips for Reducing Indoor Humidity

  1. Turn off your indoor humidifier.
  2. Ventilate your home regularly.  Open it up for a few minutes each day.
  3. Run your exhaust fans more often, and for longer.
  4. Add a basement dehumidifier.
  5. Make sure your clothes dryers are adequately vented.
