Why Your Colorado Springs Windows Fog Up, and How to Fix It<\/h1>\n\n\n\n

At over a mile above sea level, Colorado Springs has panoramic skies, crisp air, and epic mountain views. But there\u2019s one not-so-scenic thing many homeowners here have in common: foggy windows.<\/p>\n\n\n\n

Condensation on your windows is more than just a nuisance; it can be a sign that something\u2019s out of balance between your indoor environment and the technology built into your windows. Thanks to our elevation, temperature swings, and dry-but-tricky climate, this problem shows up more often than it does at sea level.<\/p>\n\n\n\n

Let\u2019s break down why your windows fog up, what\u2019s going on behind the glass, and how to fix it.<\/p>\n\n\n\n

Fogged-Up Windows at Altitude? You\u2019re Not Alone<\/h2>\n\n\n\n

Condensation on the inside of your windows is a sign of one thing: moisture in the air meeting a surface that\u2019s colder than the dew point. That just means that warm, humid air is hitting cold glass. The moisture has to go somewhere, so it clings to your windows.<\/p>\n\n\n\n

In Colorado Springs, night-time temps often drop sharply even after a sunny day, so that glass can get cold fast.<\/p>\n\n\n\n

If you\u2019ve ever noticed beads of moisture forming on your window panes first thing in the morning, or a hazy fog building up in corners, you\u2019re seeing science in action. But this problem is solvable.<\/p>\n\n\n\n

What Causes Window Condensation?<\/h2>\n\n\n\n

The Science Made Simple: Dew Point, Humidity & Glass Temperature<\/strong><\/h3>\n\n\n\n

Let\u2019s compare a window to a glass of ice water on a warm day. That little puddle forming on the outside is condensation. The same thing happens with your windows, only instead of ice water, it\u2019s cold outdoor air cooling the glass, and the warm room is your home\u2019s heated interior.<\/p>\n\n\n\n

When the temperature of the glass surface drops below the dew point of the indoor air (which depends on how humid your home is), water vapor condenses.<\/p>\n\n\n\n

Why It\u2019s Worse in Colorado Springs<\/strong><\/h3>\n\n\n\n

Homes in Colorado Springs are built for weather extremes with energy-efficient windows<\/a> that keep heat in and cold out. But when moisture gets trapped inside, and the window\u2019s interior surface gets cold overnight, you get fog.<\/p>\n\n\n\n

Unlike lower-altitude climates, where humidity might escape through older, leakier builds, modern, tightly sealed homes hold onto every bit of moisture. With wild daily temperature swings, your windows go from warm to cold fast, which creates prime condensation conditions.<\/p>\n\n\n\n

Common Sources of Indoor Moisture<\/h2>\n\n\n\n

If you\u2019ve got fog, there\u2019s moisture in the air. But where\u2019s it coming from?<\/p>\n\n\n\n
