/diy/ - Do It Yourself

Idk who to ask.but you guys. Clearly I have moisture issues coming in. Who do I call ? Window company ? Siding ? Roof guy?
I imagine the flashing on the window frame needs to be redone. I don't see wetness coming through the metal frame so I guess from the outside it's getting in...and then into the walls where it's settling. Fuck. I don't want to get taken to the cleaners but it's hard to scope out if these window companies I see can replace the frame + do reflashing and shit.
