Are foundation cracks always serious?

No. Hairline vertical cracks under an eighth of an inch are usually normal concrete curing. Horizontal cracks, stair-step cracks in brick and anything over a quarter inch warrant evaluation.

Does homeowners insurance cover foundation repair?

Rarely. Settlement, soil movement and poor drainage are excluded from standard policies. Sudden covered events like a burst pipe can be an exception.

Should I hire an engineer first?

Yes. An independent structural engineer works for you, not for a repair contract, and their report keeps bids comparable.

Will foundation repair hurt my resale value?

Unrepaired foundation problems hurt value far more. A documented, engineer-approved repair with a transferable warranty is what buyers want to see.
