Some homeowners are surprised to see window condensation on their newly installed windows. Condensation on the room-side surface of a window can be misinterpreted as an installation or product defect. This is particularly common in the winter months as temperatures drop and heat dials go up. 

We have good news: condensation on the room-side pane of glass (ie, inside the innermost pane) is actually a sign the windows are working and may have solved a problem that you didn’t know existed!   

 

Condensation on windows...a good thing?

 

 

If a window has been installed properly, it will not allow humidity, or heat for that matter, to escape your home.  It’s likely condensation did not form on your old, drafty windows because the air in your home flowed right out of them...and with it the precious heat or cool air that you pay for every month!
 

With properly sealed windows, humid air comes in contact with a cold surface -- in this case the glass in your windows -- and forms condensation.  Luckily, room-side window condensation is nothing to worry about on new windows!

Assuming you have recently installed windows, if the moisture is significant and you find yourself having to wipe down the sills, that’s an indication that the humidity levels in your home are likely too high. Here are a few things that can help: 

 

    Keep ventilation fans on. Bathrooms and kitchens are both big culprits for producing moisture in your          

    home. Make sure to keep ventilation fans running while cooking or showering, and even leave them on 

    after you're finished for a few minutes. 

 

    Lower your thermostat. Consider aiming for around 66°- 68°F when no one's home or overnight. 

 

    Use a dehumidifier.  Dehumidifiers are most often used in basements but can also help quite a bit in other 

    rooms in the home prone to higher humidity levels, like bathrooms. 

 

    Store firewood outside.  Freshly cut firewood contains a large volume of water that evaporates into your 

    home when stored indoors.   

 

     Consolidate house plants into fewer rooms.  Plants release moisture into the air and can dramatically 

    impact the humidity levels in your home. Try not to over-water plants as well. 

 

    If you have new windows -- use them! You can simply crack open a window for a few minutes to let some 

    dry air in and balance out humidity levels.
