When do you know you need new windows?
Let’s see…if they look like this?
It’s probably quite cold in your rooms, all the time. If you put your hand by the window you can feel a draft. There might be mould, yes mould, growing on the inside of your windows and on the inside frame in your room.
There also might be condensation creating that by mould (read about condensation on the Kiltox website). You must get rid of it for warmth and for your health and the health of your family. It is unfortunately the case in all 3 bedrooms upstairs as well as the bathroom and corridor. This horrid displays appear within just one week. You clean weekly and it comes back. How to fix it? Replace the windows.
