What Does Condensation on Your Home’s Windows Mean?You see drops of moisture on the inside of your windows. Your windows are leaking, right? Actually, no. That’s condensation. Home window condensation is a sign that your home’s interior has too much humidity.

How Does Condensation Form Inside Your Home?

Home window condensation happens when moisture gets drawn out the air by a sudden change in temperature. The most common example of this happens during the winter when heated air interacts the colder air around windows. As the warmer air begins to chill out, the moisture in it has to go somewhere. That is when condensation droplets appear on the inside of your windows.

Can Condensation Happen Year-Round?

While condensation happens most often in winter, it can actually happen year-round under different circumstances. Some conditions are temporary. Others are more permanent.

Temporary condensation problems occur when an excessive amount of moisture comes into the house. This can happen when you are remodeling or adding an addition. Building materials often have high levels of moisture. That moisture gets released into the home as the materials dry out.

Humid summers are another culprit. The moisture infiltrates every corner of the house. One cool day, and that moisture starts coming out in the form of condensation.

Temporary condensation problems usually resolve themselves in a week or two. Permanent condensation problems are another story.

The most common cause of permanent condensation is poor ventilation. Moist air gets trapped inside your home. This can happen if you do not have enough attic ventilation or if you do not have any bathroom or kitchen ventilation. In some cases, the moisture becomes high enough to cause condensation problems.
