Are brick chimneys attached to the house with fasteners of some sort ,
or are they usually built free standing next to the house? I was on
the roof yesterday inspecting my chimney and when I gave it a bang
with my fist, it seemed to move a little. I don't see any signs of
leaning or crumbling, but I was just curious how it attaches to the
house. I was thinking of getting a U-shaped bracket to attach it to
the house, I don't know if its necessary or not. This is a split-level.
