How to Prevent Condensation and Sweating on WindowsBy: Danny Lipford
Condensation or sweating on the inside of windows during cold weather is caused by high humidity inside your home and single pane windows that allow cold outside air to come into contact with heated air inside your home.
To prevent condensation on windows:
- Run vent fans in bathrooms when showering or bathing.
- Turn off vent fans in the kitchen when cooking.
- Have you heating and cooling system inspected to make sure it’s running properly.
- Install storm windows or replace single pane windows with insulated glass windows.
- In extreme situations you also may need to install a dehumidifier in your home.

Melissa asks: What causes my windows to sweat?
Danny Lipford: Now, that is probably the most common question I’ve heard over the last couple of years, and it is quite a problem for a lot of homeowners regardless of the type of windows that you have. Now, condensation on the inside of windows is simply a result of excessive moisture in your home. And that emphasizes the need to use, on a regular basis, your kitchen and bath exhaust fans.
Also, you want to make sure your heating and cooling system is working properly to keep your humidity in your house under control. Now, to see if you have any kind of a problem like that you can pick up one of these. It’s a very simple hydrometer, only costs about $20, and it’ll tell you exactly the percentage of relative humidity you have in your home.
Ideally, you need it to be below 40% to control condensation on your windows. And in more severe situations you may have to install a de-humidifier.
