It really depends on the type of crack.
A horizontal crack in a basement wall is bad news, because walls span vertically from the floor to the footing. Once the wall cracks that way significant strength is lost ... recommend an SE for that.
For vertical hairline cracks that are not moving (careful there) ya can epoxy inject them which works well with stabilized hairline cracks, or rout and seal with a polyurethane sealant. There are also other hydro-active injection products that can be used for active water leaks.
Recommend a good SE if ya suspect anything unusual, or recommend a good foundation repair contractor for minor non-structural cracks.
