on the front of our house we have a 30' x 5' slab of concrete that
acts as a step and patio to the ft door. There is also a reqular
sidewalk ahead of that to access the ft door.
The large slab has been settling down and away from the house
(rotation..not sliding). There is now a 1"-2" crack btwn the house
and slab. A thick application of caulking was applied when we bought
the house in 2000.
Is this something to be concerned abt structurally? Could the
rotation of the slap press against our bsmt walls and cause damage?
Or is this mostly cosmetic? If I was to consult a pro, who would I
