How to Deal With Window Condensation

Condensation is generally regarded as a problem when it forms on windows. Fortunately, this is not often the case. As your windows installation expert, Renewal by Andersen® of Long Island shares a closer look at window condensation and how you can address it.

How to Deal With Window Condensation

The Causes of Window Condensation

Condensation forms when moisture in the air comes in contact with a cooler surface. For instance, the condensation that forms outside a glass of cold water is the moisture in the air making contact with the cold glass. It’s important to make the distinction that in many cases, condensation isn’t a problem in itself. It’s also important to note where the condensation is forming, as it will be a factor in what you should do next.

If the condensation forms on the indoor window surface, you won’t need replacement windows just yet: it means that you have unusually high indoor humidity. However, if the condensation is forming outside, or between the glass panels, it means your window seals may already be damaged – in this case, you will need to have them checked by a window expert. Condensation between the glass panels sometimes comes with other symptoms, such as the glass panels pressing close together, which indicates that your insulating gas fills are leaking.

How to Prevent Condensation

Increased indoor humidity is easy to deal with. Just make sure your air conditioner isn’t turning off and on too fast (or “short cycling”). Flush out the excess humidity by opening your windows for at least 15 minutes a day. If the condensation forms in other areas as previously mentioned, have your windows checked by a professional. Depending on the condition of your windows, they could be fixed with repairs, or you may need to consider a full replacement.

If it comes to the latter, you will need replacement windows that are built to prevent problems such as condensation and heat transference.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
