How to stop condensation on my house windows?
Open you windows, or leave them on vent if you have that facility on your windows. It is the heat generated by your central heating which forms condensation on the windows, and if those windows are closed, then it has no where to go, similar to what happens in the bathroom when you have a bath or shower with the window closed, or when you cook in the kitchen with the window closed. Such an environment can also cause damp patches on your walls in the corner of your rooms, left untreated, the damp grows into black mould spores and then comes through your paint or wallpaper onto the surface of the wall, if left it will carry on growing like a plant. Happy New Year!
It is a basic physics that if a surface is cold enough and there’s enough water vapour in the air then it will condense. This means in the case of windows whether they are double-glazed or not that if the windows are cold enough and there is enough moisture in the air then condensation will occur. Condensation can be caused by a whole host of reasons – washing drying on a rail/tumble dryers/kitchen stuff etc etc. There is a lack of adequate ventilation and possibly not actually enough heat to evaporate the moisture. Condensation is also affected by the types of windows you have, metal ones are especially bad e.g. Crittall type as they warm up at a different rate to the air on either side of the window. I always ensure that I wipe the windows down completely to remove all the moisture – make sure the window and glass are totally dry and then provide a trickle of ventilation while leaving the heating on. There is a root cause to condensation but it will vary from house to house. Ours was
