Cardea Construction Company has installed new windows for a number of our customers and they are now, with this cold weather, seeing a lot of water or frost on them. This is called condensation and it’s formed when warm moist inside air comes in contact with the cold air from the outside. You think it’s bad, but actually that is what should be happening. The new windows are doing what they are designed to do, to be energy efficient—keeping the warm (and yes, moist) air in the house.

condensationOlder windows are less efficient, and allowed moisture to escape, so you don’t see the condensation on the inside of the window. With your new windows, in winter, you very likely will see some— especially in Michigan, in the morning. When combined with the additional water vapor (moisture) from showers, cooking, or from clothes dryers not vented to the outside, the result is excess moisture and a high relative indoor humidity level.

There are things you can do about excess condensation caused by high humidity.

Some moisture is expected especially during the time when there is a large temperature differential between inside and outside your home. And some moisture is really good for both the house and you—remember the times when no matter what you touched—you got a shock? With a controlled amount of humidity in the house during these winter months, that should be a thing of the past.

But excessive moisture in the house can produce some real problems that you want to avoid. You have the ability to control the humidity inside your home. If your condensation is “extreme,” you should do something to alleviate it. You can:

  • Turn off any humidifying devices in your home for short to reduce the humidity in the house.
  • Use your dehumidifier to reduce the amount of moisture in the air.
  • For a few minutes each day, open a window or door to let dryer, cold air in while allowing some of your warm, moist air escape.
  • Run exhaust fans in the kitchen and bathrooms to increase air circulation throughout the house; if you do this with a kitchen or bathroom window open, it will be even more effective.
  • Keep the drapes or blinds on your windows at least partially open, allowing air to circulate against windows.
  • Open fireplace dampers to allow an escape route for moisture-laden air.
  • Add waterproofing to basement floors and walls to decrease accumulation of moisture in the house.

When do you know if you have a problem?

If you see condensation in between the layers of glass in an insulated window, the window’s seal has probably been broken and the window will need to be replaced. Contact Cardea Construction Company to replace one or all your windows.
