Foundation Repair in Sunnyvale — FAQ

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.
