How much does a foundation pier cost?

$300 to $800 for concrete pressed piers, $1,000 to $2,000 for steel push piers and $1,200 to $2,400 for helical piers, installed.

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.

Pay an independent structural engineer $400 to $1,200 first so you buy the repair you actually need, not the one being sold.
Fix drainage, gutters and grading — many settlement problems stop progressing once water is controlled.
Get three bids with pier counts and depths spelled out; counts vary wildly between contractors.
Ask about interior versus exterior pier placement — exterior is usually cheaper.
Choose a company offering a transferable lifetime warranty; it protects resale value.
