Hi
I have a damp patch along the inside of my upvc upstairs bedroom window. It runs from the top of the window frame down to the cill. The window is about 8 years old. There is a plastic strip which covers the gap between the frame and the plaster. The damp is on the plaster side of this. It looks like it has only recently started and there is no mould or damage to the plaster.
Where do i begin looking to find the cause of this?
Thanks
