The Christmas Tree Looks Amazing. Why Is the Window Behind It Foggy?

You spent two hours untangling lights.

You strategically rotated the tree until the good side faced the room.

You hung every ornament.

You stepped back.

Beautiful.

And then you noticed the window behind it looks like someone breathed on it for six straight hours.

December is prime window-condensation season.

So what is actually going on?

Some condensation can be normal

When warm indoor air contains moisture and hits a very cold surface, condensation can form.

That is why you may occasionally see moisture on the interior side of windows during cold weather.

Cooking, showers, humidifiers and even having a house full of holiday guests can raise indoor humidity.

The more moisture in the air, the more likely you are to see condensation on cold glass.

But where the moisture appears matters

Condensation on the room-facing surface of the glass is different from condensation trapped between panes.

If moisture appears inside a double- or triple-pane insulated glass unit and cannot be wiped away from either side, that can indicate a failed seal.

And unfortunately, no amount of Windex is going to solve that one.

Pay attention to repeated problems

A little moisture during extremely cold weather is one thing.

Persistent condensation, frost, damaged frames or water collecting around the window deserves attention.

Moisture can eventually affect surrounding finishes and materials.

It is also annoying.

Especially when you are trying to look outside at a beautiful Michigan snowfall and instead you are admiring fog.

Your humidity may be part of the equation

Winter air can be dry, so many homeowners use humidifiers.

That can make the house feel more comfortable.

But too much indoor humidity during very cold weather can increase condensation on windows.

If you are seeing moisture throughout the house, indoor humidity may be worth checking.

Sometimes the window is telling you something

If windows are older, difficult to operate, permanently cloudy between panes or noticeably drafty, winter tends to expose those weaknesses very quickly.

Homeowners considering replacements can explore options from North Star Windows & Doors and ProVia.

Because windows should provide a clear view of the Christmas lights outside.

Not create their own weather system.
