What changes the price

Soil type

Expansive clay soils (Texas, Oklahoma, parts of California) move 4 to 6 inches per season and drive most US underpinning jobs. Sandy soils settle but rarely heave.

Pier count and depth

Each push pier runs 1500 to 2500 dollars installed. Helical piers cost 1800 to 3000 dollars and reach bearing strata in saturated soils that push piers cannot.

Access and obstructions

Slab-on-grade homes need tunneling under the foundation, adding 6000 to 12000 dollars over crawl-space access for the same number of piers.

Frequently asked questions

How long does foundation repair take?+

Pier installation runs two to five days for a typical six- to ten-pier job. Mudjacking finishes in one day. Full helical perimeter work can take a week.

Does homeowners insurance cover foundation repair?+

Almost never for settlement, expansive soil, or hydrostatic pressure. Insurance covers sudden events such as a vehicle impact or a documented plumbing leak.

How do I know if I need foundation repair?+

Diagonal cracks wider than a credit card, doors that no longer latch, gaps between trim and ceilings, and exterior brick stair-step cracks are the strongest signals.

Will foundation repair lower my home's value?+

A documented, warrantied repair usually maintains value. Unrepaired structural damage discounts the home 10 to 15 percent in most appraisal reports.

Can I DIY any foundation work?+

Surface crack sealing and minor drainage grading, yes. Underpinning, wall anchors, and pier work require licensed contractors and almost always a structural engineer sign-off.
