If your windows are full of condensation, don’t let it drag on. Your whole house could burn down. Here’s how you can easily get rid of it.

After a warm start to September, the cooler weather of autumn is making itself felt. Even if we want to enjoy the sun a little longer, the cold and damp weather is approaching. The colder the air outside becomes, the greater the risk that the windows will be covered in condensation. Condensation forms when the warm air inside the house comes into contact with the cold surface of the windows. Although it is harmless in itself, it can lead to the growth of mold.

Mold can cause health problems such as allergies, asthma, and other respiratory issues. Therefore, it is crucial to address condensation issues as soon as they occur. But what can you do to prevent condensation this fall? If you notice condensation on your windows, it doesn’t necessarily mean you need to replace the windows. Condensation can build up on any window, and there’s not much you can do to prevent moisture from building up on windows because moisture also builds up when you breathe.

Air: Opening your windows in the autumn or winter may not sound like a good idea, but it can be essential to ensure good air circulation in your home and allow damp air to escape. If your home is prone to condensation, damp or mould, the best thing you can do is try to improve indoor ventilation. Try to open your windows regularly to allow air to circulate freely and moisture to evaporate. Ventilation systems such as extractor fans can also help to significantly reduce the build-up of condensation in the home.
