Hi, we had tatty plastic trim around the sills (top, sides, and windowsill) of our window and decided to replace.
After removing the top one I wish I hadn't, because it has revealed a gaping void up to the area between the fascia and the soffitt.
There is nothing fixing the top of the window to the wall.
Assuming this isn't normal, what should be there and what can I do to sort it?
Any help appreciated.
