Window condensation: Tackling mould risks and simple solutions

In the fall, we wash windows less often. Understandably, the weather isn't conducive to this activity. However, condensation can be more bothersome than streaks at this time of year. This often affects kitchen windows. There's a simple solution for it.

Foggy windows are not just an aesthetic issue but also a health concern. Moisture always facilitates the growth of mould. So if droplets of water are forming on your windows, it's time to take action.

Do you wake up in the morning when the windows are foggy? This is a common sight, especially at this time of year. The reason is simple — the temperature outside drops while it remains warm inside the home. Water vapour forms due to the temperature difference and condenses on cold surfaces. Windows are an ideal place for this. Water droplets appear on them most often when the air in the home is humid. This is primarily due to cooking and laundry. At night, as the temperature drops, moisture settles on the cool glass, which is why we have foggy windows in the morning.

Foggy windows don't look very aesthetic, but if this problem happens sporadically, it's not a major concern. It becomes much more serious when windows are constantly foggy. Prolonged moisture on windows can lead to the development of mold and fungi, which are very detrimental to health. Mold can also damage window frames, especially those made of wood.

One of the simplest ways to handle foggy windows at home overnight is to wipe the glass from the inside with a 1:1 solution of water and vinegar. This creates a protective layer and reduces condensation buildup. In the evening, apply a bit of the mixture to a dry cloth and gently wipe the entire surface of the glass. You can add a little dish soap to the mixture to help the vinegar adhere longer to the window surface.

• Installing air vents. They ensure air exchange without cooling down rooms and losing heat.
• Loosening window seals. Most windows come in micro-opening or micro-ventilation mode. By setting the handle in the appropriate position, the pressure on the window frame decreases, leading to a slight loosening of the window. The resulting gap allows for air exchange.
• Regular ventilation. On cold days, when we don't want to lose heat and burden heating systems, it's best to ventilate the apartment briefly and intensively.
• Air dehumidifier. These devices mechanically remove moisture from the air.
• Checking the ventilation ducts. If the problem of foggy windows recurs despite ventilation, consult a chimney cleaning company to check the operation of the ventilation ducts.
