If Your Windows Frequently Get Condensation, Does That Mean They Should Be Replaced?

Condensation is a relatively common problem in homes in winter. Knowing what to do about this problem can help you prevent damage to your home and can help you preserve and maintain your windows.

If your windows frequently get condensation, does that mean they should be replaced?

Frequent formation of condensation is not necessarily a sign that your windows need to be replaced. It is more of a problem with your home's humidity or moisture levels than it is a problem with your windows.

Why does condensation form on windows?

When the air outside is cold, the glass in the windows also becomes cold. Warm, moist air inside home touches the cold surface of the window and the temperature of the air around the window drops. When that air reaches its dew point, the moisture in the air is deposited on the window, and condensation is formed. Although it may help to get insulated, double-paned glass, the larger problem (moisture in your home) will still exist.

What can you do to stop condensation from forming on your windows?

You can stop the formation of condensation on the windows by reducing the moisture in your home. There are many ways that you can do this:

  • Fix any leaks. Water leaks inside the home can contribute to the development of condensation. Fix any leaks in your roof and in your plumbing. If you're not aware of any leaks in your home, have your home inspected by a plumber and roofer.
  • Run ventilation fans whenever possible. Turn on the vent over your kitchen stove and in your bathrooms whenever you use these rooms.
  • Use a dehumidifier. Dehumidifiers can help reduce moisture levels in your home. Place the dehumidifier next to the most problematic windows.
  • Run climate control. Running your home's HVAC system will help you dehumidify your home.

What should you do if your windows have become damaged by the condensation?

Condensation on windows can be damaging (particularly for wooden windows) if the water drips down to the sash and window frame over many months or years. Windows that have become water damaged over a long period of time may become very rotten. Rotten wood in your windows must be replaced. If a high enough percentage of the wood in the window frame and sash is rotten, you may need all new windows. Talk to an experienced windows contractor for an inspection of your windows to find out if repair or if an all new window installation is necessary.
