Do I need a structural engineer or a contractor?

For diagnosis and a neutral repair spec, a licensed structural engineer is best; the repair itself is done by a licensed foundation contractor.

How much does foundation repair cost?

Minor crack sealing can be ~$2,000; helical piers or full underpinning can reach $25,000+.

Are foundation cracks always serious?

Not always — hairline cracks are common, but horizontal cracks, stair-step cracks, and doors that stick warrant a professional assessment.
