It looks like the timber is completely rotten and there's a big hole in it in that corner, you'll need to address that surely.
We can live with a section being rotten as long as we can fix the ingress so the rot doesn't spread.It looks like the timber is completely rotten and there's a big hole in it in that corner, you'll need to address that surely.
Ah do you mean this bit? The screws don’t look too bad and it’s not showing too much signs of wear unlike the previous pics..Hi Peter
Sorry for the delay! I wasn't referring to that cover flashing! I meant the piece that sits on the side of the frame and is screwed into the wooden frame. I tried uploading a picture but it keeps telling me to accept cookies which I consent to but it still won't let me send a picture....
