Fogged glass is fun for children, who like to draw and write messages on windows. However, if a fixture frequently experiences condensation, it may be facing problems. The guide below contains answers to common questions about this issue to help you decide if your glass needs attention.

What to Know About Foggy Windows 

What causes condensation on glass? 

Warmth and moisture in the air combine to create humidity. When it touches a cold surface, like glass, it generates droplets and fog.

If you see fogged glass on your window, it means that the surrounding air is humid. In most cases, this is caused by rain or steam from showers, baths, cooking, washing clothes, and dishwashers.

How can excess humidity affect your home? 

In small amounts, humidity is fine, and can even help your plants stay healthy.

However, consistent exposure encourages mold and mildew growth, which can trigger allergic reactions. High levels of humidity can also cause wood to rot, peel, and warp.

How does humidity enter my home?

Cracked glass and poor seals on doors and windows allow moisture through. If you notice these issues, use caulk to seal gaps or call an expert for glass and window repair.  

To find out if your windows provide adequate protection from moisture, run a finger across any fogged glass when it rains. If your skin becomes wet, humidity is penetrating your home, so schedule window replacement. If your finger is dry, the condensation is outside the window, which means your house is properly insulated. 

What can you do to reduce humidity? 

Keep your vents open and clean the ducts of your HVAC system to promote adequate ventilation.

If you use a humidifier in the winter, when condensation and fog are most prominent, keep it to a low level. This should be around 45%.
