Why the hills are the whole story here
A 1940s bungalow off Dickson Street can drop a corner two inches because grading done before the war finally finished consolidating. Add expansive clay, steep cuts and eighty years of oak roots drawing water out of the soil each summer, and you get a city where foundation movement is normal rather than exceptional.
Practically, that means the repair depends on which side of town you are on. Shallow-limestone homes north of Maple usually need crack stabilization and drainage. Deep-clay homes to the south need underpinning that reaches through the active zone. Quoting one solution for both is the mistake we most often get called in to correct.
