Thin vertical cracks
Common in poured concrete as it cures. Keep an eye on it. If it widens past ⅛ inch or lets water in, have it checked.
What the cracks are telling you
Most foundations crack a little. Direction and width tell you whether yours is cosmetic or moving.
Stair-step cracks
A crack zig-zagging through the mortar of a block wall means part of the wall is settling unevenly.
Horizontal cracks
Soil pressure is pushing the wall inward. These tend to get worse with each wet season, and bowing usually follows.
Doors and windows that stick
Frames go out of square when the house shifts. Watch for gaps at the top of a door.
Floors that sag or bounce
Over a crawl space this often means damp joists or sinking support piers.
Water, white residue or a musty smell
Chalky white deposits on walls (efflorescence) mean water is moving through the concrete.
