Mr. Fixit.....
I've taken a first floor, bearing wall, with a 2nd story floor system, cantilevered 2', that was carrying the truss load, in fully occupied home, that was so ate up by Subterranean Termites, that a bulldozers bucket Could NOT lift up ( due to the Load) the 2nd story and roof up, to replace the 2x12 headers and bearing wall! I did it , alone... no BS At all....
