Questions
Is this checker a substitute for an inspection?
No. It gives you a quick, general read based on common warning signs. Only an on-site inspection with elevation readings can tell you whether your foundation needs repair.
Are hairline cracks normal?
Small hairline cracks are common as homes settle and as seasons change. Cracks that widen, run diagonally from door and window corners, show up in brick, or keep coming back are more worth checking.
