What Does Condensation on Your Windows Mean?

When it comes to your home’s windows, it might be easy to assume that if you don’t see any breaks or cracks, all is fine. But not so fast, especially if you notice condensation. Condensation occurs when warm, moist air comes into contact with cooler surfaces—moisture in the air condenses into water vapor and beads into the surface of the lower temperature surface. Condensation occurs because the cooled air next to the cool surface can’t hold as much moisture as the warmer surrounding air.

While exterior condensation is a form of dew that you’ll notice on your window because excess moisture from the air needs a surface on which to condense, it’s worth a closer look to check for interior condensation.

Take a look at what interior condensation could mean and why you should hire a professional if you notice it. Then, contact the team of residential window repair experts at Fast Glass in Highlands Ranch, CO, to schedule an appointment if your windows are in need of repairs.

What does interior condensation indicate?

First, it’s important to note that you may notice interior condensation taking one or more forms. It may block the view, making it difficult to see out of your window. This interior condensation indicates excess humidity in your home, which means that this condensation may be causing other humidity-related problems. Excess humidity may lead to one or more of the following:

• A damp feeling in the home, usually present around heavily windowed areas
• Staining or discoloration of vinyl or wood surfaces
• Visible mold or mildew on sills or a musty smell
• Warped wooden surfaces and window frames
• Cracking, peeling or blistering on paint around the window
• Damages to materials around the window frame

Ultimately, condensation can mean a couple of things in relation to your windows. First, it could mean a broken seal, which can taint the equilibrium between your panes, which increases convective heat transfer, raising the dew point. Second, it could mean there are unseen gaps around the frame of your window, which can cause the same issue. Either way, your windows need to be closely inspected and the issue resolved if it’s determined to exist.

Why should I take care of this problem?

Given the effects that can take place because of interior condensation, seeking immediate repair is a priority so that your home can return to its comfortable, aesthetic appearance as soon as possible.

Beyond affecting your home’s appearance and structure, the excess humidity that results from this interior condensation can also affect your health. Most experts suggest maintaining indoor humidity levels between 30 and 50 percent. At levels higher than 65 percent, upper respiratory afflictions may occur in those who experience asthma and allergies, according to the World Health Organization.

Condensation is more likely to occur in climates where the average January temperature is 35°F or colder. While it’s most common in winter, it can occur at any time during the year when water vapor in the air comes in contact with a surface wherein the temperature is lower than the dew point of the environment.
