I have these three wood awning windows in the basement. Because the leaked deck(Fixed now) above, the top frames of the window are rotten. Can the windows be repaired or it's more cost efficient to replace them? These windows are only 8 years old and I don't know who made these. Here are the pics of the rotten windows.
First, inside view
2nd, inside close up
3rd, outside view
4th, close up view of rotten wood behind the rubber seal
