Questions
Short answers about cracks, insurance, cost, and engineers, each linked to the page it came from.
- Do I need an engineer before hiring a foundation contractor? Some cities require a registered engineer when the soil is expansive. A contractor can still call first. Ask who will stamp the plan.
- Does homeowners insurance cover foundation repair? Flood policies exclude earth movement even when water moved the soil. A homeowners policy is a different contract. Your insurer decides the claim.
- How much does foundation repair cost? This Old House estimates, in a guide updated October 8, 2026 and based on Angi cost data, that most foundation repairs cost $2,224 to $8,134. Not a bid.
- When is a foundation crack serious? A stair-step crack, a crack that grows, or a crack that moves a door or floor needs a closer look. A stable hairline can often be watched with a dated mark.
