1985 house, two stories over basement, brick veneer fro pavement to tip of 6 in 12 gable. Opposite end sports chimney column of even greater height, but chimbley has begun to bulge away from face of tall brick facade, On entry into attic I went to one gable end and then another, and pushed/pulled on endwall framing. Was able to get a pretty good sway going. Suspected from chimney bow a possible lack of brick ties. Swaying end frame seemed to nail it for me. If no ties, how to fix? What about chimbley?
