tuckpointing under window

[bubblegummom]

Hello! The young man who tuckpointed a wall of my house ground out this area on top of the window:

and he wouldn't fill it back in again because he said something about he thought there should be a piece of metal in there. Does anybody know anything about that?

Thank you!
