What settling looks like
Settling shows up as a pattern. One part of the house drops, and everything built on it bends toward that spot.
Cracks that point to one corner
Stair-step cracks in block or brick that run up and away from the low corner.
A crack wider at the top
A crack in the foundation that opens more at the top than the bottom.
Sticking doors on one side
Doors and windows on the low side drag, will not latch or have uneven gaps.
Diagonal cracks upstairs
Cracks running up from the corners of doors and windows toward the sinking side.
A floor that runs downhill
The floor slopes toward one outside wall or corner.
A porch or chimney pulling away
A gap opens where the porch, steps or chimney meet the house.
Gaps at the top of the wall
Space between the foundation and the sill, or between walls and ceiling.
