hi can anyone help i get condensation ang mould on all my windows through out my house. it seems worse this year im getting puddles on my window seels. my windows dont have vents so i try to leave the windows open a little bit but this does not seem to work.thanks
Keeping windows open in the summer may work well in keeping humid rooms such as bathrooms and kitchens dry because the outside air is dryer than inside and allowing the air to circulate evaporates any water lying about in the room.
In the winter months outside air is cold and damp. Just looking at my humidity meter now, tells me that outside air contains more moisture than inside air so letting it in is only going to bring in more water than will be removed.
Another point, incoming air will make the area around windows colder and therefore condensation is even more likely to develop.
You could reduce the amount of water vapour in the room, but that is pretty difficult unless you stop breathing and doing anything that produces steam.
Really the only effective way to reduce condensation is to make the window warmer by having double glazing and a warmer room. This is the main reason why radiators are placed under windows.
I had the same problem with [u]one[/u] of my windows and it was because the radiator under the window needed bleeding. It is working fully now and my window has dried up. You just need to keep your house at a good temperature during the winter months to avoid this i think.
