Why Condensation Isn’t Always a Sign of a Window Leak

Should you be worried about window condensation? In some cases, it could be a sign of a window leak; gaps in the window frame could allow moisture to infiltrate your interior and form condensation on the window glass or frame. However, window condensation isn’t always a sign of a window leak; it could simply be a sign indoor humidity levels are higher than normal.

How Condensation Forms on Windows

Condensation forms when a cold object makes contact with warm, humid air. In spring and fall, when the nights are cooler and the days are warmer, condensation can be found on the window’s exterior glass. And in winter, when your home’s interior is warmer than the outside, condensation can be found on the interior glass.

When Should You Be Worried About Window Condensation?

Condensation on your window’s exterior—which is a good indicator of energy-efficiency—shouldn’t be a cause for concern, but condensation on your window’s interior is. That’s because condensation can cause the paint on the window’s edges to peel off and increase the risk of mold. 

How Can You Prevent Condensation From Forming on Your Window?

By making sure your interior is well-ventilated. Any activity that involves water adds moisture to the air and increases the humidity in a room. Running the exhaust fans in damp areas in your house such as the bathroom and the kitchen can help decrease indoor humidity.

How Can You Tell if There’s a Window Leak?

You can use the incense trick: light an incense stick near the windows. If the smoke floats toward your windows, then there’s a leak. To make sure your new windows don’t let heat or cold air out, choose windows from reputable brands. Remember: when in doubt, it’s best to stick to established brands. For instance, if you need a siding replacement, choose siding options from trusted names such as James Hardie® siding.
