Condensation is a phenomenon that occurs when moisture from hot air comes into contact with a cold surface. Air saturated with water vapor then cools from the vapor state to the liquid state, resulting in water droplets and fog on windows and glass. This phenomenon often occurs when the humidity level is high and it condenses on cold surfaces such as windows. To prevent condensation from forming on windows at night, there are six solutions you should know about.
Fogging on the windows, humidity on the walls, loose wallpaper, the appearance of mold or peeling paint… There are many consequences related to the presence of condensation in the home. To avoid condensation problems, some rules are necessary.
What are the risks of condensation?
Condensation is a common phenomenon that often indicates moisture problems in the home.

Excess moisture leads to saturation of the air and excess water vapor eventually liquefies. The contact between the hot air and the cold surface creates a thermal bridge. Sometimes mold appears on ceilings, walls or bathrooms.

These fungi can be responsible for poor air quality and cause long-term respiratory problems. In addition, it sometimes happens that excess moisture causes bad odors. In addition, condensation can deteriorate the materials and coatings in the house (wood, wallpaper, paint). To prevent damage from condensation, it’s best to act as soon as possible.
How to measure the humidity level?
To find out if you have a condensation problem, you must first measure the level of humidity in your home. It is believed that an ideal relative humidity should be between 30 and 60%. You can arm yourself with a thermometer-hygrometer to make a diagnosis of humidity. Therefore, a rate above 60% is likely to have detrimental effects on health and the home. However, if the humidity level is below 20%, it does not represent a risk for the occupants of the house, but it can cause some discomfort (too dry air).
How to solve a condensation problem inside the house?
To prevent damage from condensation, it’s best to act as soon as possible.
Here are our solutions to combat condensation:
- Heat rooms where there is condensation to avoid humidity
- Regularly clean the vents to ensure ventilation performance.
- Ventilate the house daily and open windows to circulate air for at least 15 minutes, even in winter.
- Place a moisture absorber or dehumidifier in rooms with high humidity.
- Choose indoor plants to combat condensation
- Replace single glass windows with double glass windows
With these 6 solutions, you can enjoy a healthy indoor climate and protect your home from moisture damage.
