Before you sign

How to hire a foundation repair company in Oakland

1

Get an independent engineer's opinion before committing to a large repair.

2

Ask whether the warranty transfers to the next owner and what it excludes.

3

Compare pier types: pressed concrete, steel, helical, and why they recommend one.

4

Ask about drainage and watering; many problems start with soil moisture, not the slab.

Good to know

Foundation Repair Company questions, answered

Do cracks always mean foundation problems?

No. Hairline cracks in brick or drywall are common with seasonal movement. Doors that stop latching, stair-step cracks and sloping floors deserve an evaluation.

How long does foundation repair take?

Most pier jobs take one to three days. Landscaping and drainage work may follow.

Will repair fix the cracks?

Lifting the foundation often closes cracks partly. Cosmetic repairs to brick and drywall are usually a separate step.
