Foggy windows are nothing new to homeowners. Some can get really frustrated by it while others are able to tolerate this nuisance.

How to Minimize Condensation on Windows

In this article, trusted window company, Renewal by Andersen® of Southwest Missouri, discusses how condensation occurs on windows and what you can do to avoid it.

What You Need to Know About Condensation

Condensation is the result when warm, moist air comes into contact with cooler surfaces like your window glass. It’s more common in winter, but it can also happen during a warmer season or whenever water vapor from warm air touches a colder surface. A good example of this is when a glass of cold water sweats. Since the air is warm and moist, and the glass surface is cold, condensation occurs.

Indoor moisture is mostly caused by the activities you do inside your home. It results from cooking, showers or any activity that makes use of water. Vapor pressure usually forces moisture through materials like plaster, wood, brick and cement.

With regards to moisture outside your window, this often happens in spring and fall. During these seasons, the days are usually warmer and the nights cooler.

But before assuming that your windows are bad, take note that condensation isn’t entirely a bad thing. On the contrary, experts see it as an indicator that your windows are tightly sealed and energy-efficient.

Reducing Humidity in Your Home

Although it can be hard to completely stop your windows from fogging up, there are ways in which you can minimize humidity in your home. Professionals recommend homeowners to do the following:

  1. Ventilate the attic and crawl space.

  2. Cover the earth in the crawl space with a vapor barrier.

  3. Vent appliances and exhaust fans outside.

  4. Run an exhaust fan in the kitchen when cooking and in the bath until the mirror is clear.

  5. If you have a forced air furnace, ensure your home is properly ventilated.

"From initial review and purchase to installation, this team provided outstanding service. We were informed about the project status from start to finish. Everything was clear to us. We were very please the 6 windows were ready and installed earlier than originally planned. We'll work with them again on our next window replacement project."
