Why Do My Windows Have So Much Condensation?

3 min read

What is Condensation?

An air-conditioned home and summer weather can be the perfect recipe for condensation, or water droplets, on your windows. While it can potentially point and lead to larger issues, window condensation can also just be a sign that your windows are working as intended. Here’s what you need to know to determine if condensation should be a cause for concern and how to lessen its occurrence.

Condensation Causes and Simple Solutions

Window condensation mainly occurs when there are drastic differences between indoor and outdoor temperatures. However, the exact cause of condensation on your windows, and solving for it, depends on where exactly it’s occurring on your windows. Here are the three ways condensation can form on your windows and what can be done about them.

Condensation on the Outside of Windows

“Sweating” windows are most common in the summer/warmer months, when you have cooler interior window sides and hotter exterior ones. Fortunately, there’s likely nothing to worry about in cases like these, and it probably just means that your windows are working correctly. Still, there are a couple key ways to cut down on condensation.

Raise Your House’s Temperature

Simply put, a warmer home will have warmer interior glass that is not as likely to form exterior condensation. Of course, you’ll need to decide if this is worth it for your comfort in the long term.

Doing this can help boost the amount of air circulating around your windows, as well as the amount of sunlight that can reach and evaporate water droplets.

Condensation on the Inside of Windows

Moisture on the inside of windows is most common in the winter/colder months, when you have hotter interior window sides and cooler exterior ones. While it’s likely harmless, it can also be a sign of poor ventilation in your home. If it’s especially excessive, interior window condensation can potentially lead to water damage or even mold or mildew forming on carpet, insulation or even wood (for reasons like these, all Window World windows are made from high-quality vinyl). Here are some ways to lessen interior window condensation.

Solve Home Ventilation Issues

Things like your laundry room and your fireplace can be hotbeds for creating excess humidity. If these are problem areas in your home already (e.g., exhibiting mildew or mold), fixing them will help cut down on window condensation.

Circulate Interior Air

By leaving interior doors open, using ceiling fans or even cracking open your windows (if the weather permits), you help prevent humidity—and the potential for condensation—to build up too much in one place.

Use Dehumidifiers

Taking water out of the air can help with window condensation. Plus, you’ll get to experience all the health and comfort benefits that dehumidifiers offer too.

Run Exhaust Fans

Your kitchen and bathroom may already have these—they’re a great way to offset the moisture that goes into the air while you cook and shower.

Condensation Between Your Window Panes

If you have double- or triple-ply windows, condensation between your window panes (e.g., the sheets of glass in your window) is the one place where you really don’t want it. If there are water droplets living between panes, it points to larger issues with your windows (most likely faulty sealing that allowed moisture to get in). While repair may be possible, this may be your cue to consider high-performing window replacements.

All Window World’s Windows are made with Intercept™ spacers that enable them to expand and contract with temperature changes. So while conventional windows wear down their sealant during these times, our windows resist this movement and premature sealant failure.

Don’t Let Condensation Bring You Down

While condensation can be bothersome and obscure your view, as long as it’s only happening on the inside or outside of your windows, you may not have anything to worry about. Of course, there is much more to window quality than just condensation or a lack of it.
