Do you ever wonder about the fog or moist that builds up on your window panes when it’s cold outside? Do you know what causes it and why it’s a sign of window failure?

NEXT Door & Window, the top provider of windows in Illinois, answers some frequently asked questions about windows and what causes condensation:

What’s that moisture building up on my windows?

That moisture is called condensation. You probably heard about condensation when you were still in school. When it comes to windows, condensation is that water or moist buildup you see whenever there’s a drop in temperature outside your home. When warm air mixes with cool air, condensation forms. It’s similar to how your bathroom mirror fogs up when you take a hot shower on a cold day or during the evening.

What’s causing our windows to sweat?

The windows of your home are exposed to different climatic environments. During winter, for instance, this happens when there is a great difference between indoor and outdoor temperatures and when the warmer side has a high relative humidity.

Why should I worry about condensation in my home?

Windows with too much moisture or condensation means that they are failing in protecting you from the elements. Too much condensation may lead to peeling paint and mold or mildew growth, which may result in various health problems. It may also cause window frames and other wood components to rot. Condensation may also be a sign of poor insulation, which can increase your energy usage as your HVAC system tries to maintain a comfortable temperature inside your home.

What should I do if I see window condensation in our home?

The best thing to do is consult specialists on windows in Illinois to have your windows assessed. Depending on the issues found, you may need to either repair or replace your windows.

Condensation is a serious problem. If there’s too much condensation on your windows, don’t wait until problems occur before you have your windows checked. Get in touch with us at NEXT Door & Window for expert recommendations.
