Why is there Condensation on my New Window?

Person Cleaning Window and Window Sill

As a custom window replacement company serving Yardley, PA, we often hear questions from homeowners about why their newly installed windows have condensation on them. There are multiple ways to relieve the problem; but first, let’s figure out why it happens in the first place.

Why Does Condensation Appear on Windows?

Condensation appears when humid air comes into contact with a surface or with air, which is at a comparatively lower temperature. Air carries water vapor — the warmer the air, the greater the capacity for holding water vapor. When warm, moist air encounters a cooler surface or air, its temperature drops and it loses some of its capacity for holding moisture. To compensate, some of it is released to create condensation in the air in the form of steam or, on a hard surface, in the form of water droplets.

People often see this happen when taking a shower when the mirror fogs up, or when having a cold drink on a steamy summer day.

How Can I Get Rid of Condensation Buildup?

It can be rather annoying when you buy new windows and you can’t even see out of them! However, this does not mean that the windows are faulty or were installed incorrectly. In fact, having condensation on your brand new windows shows that they are functioning correctly! If your old windows were not experiencing condensation buildup, that means the outside air was blowing through your windows — those drafty windows needed to be switched out.

So, now that we know that the presence of condensation on your new windows is a good sign, what can you do to fix it? Check out our video for a few tips on banishing condensation from your brand new windows, as well as the checklist below:

  • Be sure your vents are opened in your home.
  • Open up your windows (when practical) to let the interior moisture escape.
  • Turn on your ceiling fans to keep the air circulating in your home.
  • Turn on the fan in your kitchen during and after cooking to let out the hot air.
  • Use the fan in your bathroom during and after your shower to let out the steam.
  • Use a dehumidifier.
