Why Is There Condensation on My New Windows — And What Can I Do About It?

If you’ve recently upgraded your windows and started noticing moisture on the glass — especially in the mornings — you’re not alone. Many homeowners are surprised (and even concerned) when they see condensation inside windows in the morning, especially when their old windows didn’t seem to have this problem.

Let’s clear up the confusion.

What Causes Window Condensation?

Condensation happens when warm, moist air comes into contact with a cooler surface — like the inside of your window on a cold winter morning. That moisture in the air turns into tiny water droplets on the glass, creating fog, mist, or visible dampness.

Sound familiar? It’s the same thing that happens to a cold drink on a hot day. The cold surface meets warm, humid air — and it “sweats.”

In homes, the most common time you’ll notice this is overnight or in the early morning, especially in colder seasons. That’s why many people search “how to stop condensation on windows overnight.”

Is Condensation on New Windows Normal?

Yes — and it’s actually a sign your windows are doing their job.

Older, drafty windows allowed more air exchange, which helped excess humidity escape (along with your heat and energy dollars). But modern, energy-efficient windows are sealed tighter to prevent heat loss. This means moisture stays trapped inside — especially in the winter months.

So if you’ve recently upgraded and are wondering about reduced condensation with new windows in winter, the shift is likely due to your home now holding more humidity — not a problem with the windows themselves.

How Everyday Life Adds Moisture to the Air

You might be surprised at how much humidity your daily routine adds to your home:

• Cooking three meals a day can release up to 5 pints of water into the air.
• Every shower adds another half pint or more.
• Running a humidifier, drying clothes indoors, or watering houseplants all contribute too.

And that moisture doesn’t stay put — it moves around your house. So even if your kitchen or bathroom is on the other side of the home, you may still see condensation inside windows in the morning in your bedroom or living room.

When Should You Be Concerned About Condensation?

Some moisture is completely normal, but too much can lead to problems, including:

• Mold and mildew growth
• Damage to wood trim, paint, or drywall
• Frost buildup inside window frames
• Long-term damage to insulation and walls

If you're wondering how to get rid of condensation inside windows, it’s important to reduce indoor humidity levels while maintaining comfort.

How to Reduce Condensation on Windows

Here are practical steps you can take right now to reduce moisture and prevent window condensation:

✅ Turn off or reduce humidifier usage
✅ Open blinds and curtains to improve air circulation
✅ Use ceiling fans to move air in cooler months
✅ Increase your home’s air temperature slightly
✅ Run exhaust fans during and after cooking, bathing, and laundry
✅ Ensure bathroom fans stay on for 15–20 minutes after showers
✅ Vent gas appliances, dryers, and fans to the outside
✅ Avoid storing firewood indoors
✅ Cover crawlspace dirt floors with vapor barriers
✅ Limit houseplants or group them in sunny rooms
✅ Make sure your attic and crawlspaces are properly ventilated

By combining these steps, you’ll not only reduce condensation — you’ll also improve your home’s overall indoor air quality.
