It depends on the crack type. Hairline cracks from normal settling are usually cosmetic. Horizontal cracks indicate pressure and are concerning. Stair-step cracks in block foundations suggest movement. Wide cracks (>1/4 inch) or those growing quickly need professional evaluation. When in doubt, get an inspection.
Standard homeowners insurance typically does NOT cover foundation problems caused by settling, poor drainage, or normal wear. It may cover sudden damage from covered events (plumbing breaks, fallen trees). Check your policy and consider foundation-specific coverage if in a high-risk area.
Quality foundation repairs are designed to be permanent. Pier systems and wall anchors are engineered to last the life of the home. Reputable companies offer 25-year to lifetime transferable warranties. The key is addressing the root cause (drainage, soil) alongside symptoms.
