Straight answers

What do most foundation repairs cost?

Most land between $2,200 and $8,200 by Fixr's 2026 count, centering on $5,200, and This Old House reports $5,179. Piers run $1,000–$3,000 each, so a job's total mostly follows the pier count. Piering an entire house is the top band, $10,000–$40,000.

Why do so many San Antonio houses have foundation problems?

Mostly the clay. The NRCS rates about 92% of rated Bexar County soil acreage as limited for homes on a concrete slab, chiefly for high shrink-swell (USDA NRCS). Add long hot summers and sudden heavy rain, and the ground under a house rises and falls through the year.

Does San Antonio require a permit for foundation repair?

The City of San Antonio lists foundation repairs among residential permits issued over the counter. A homeowner pulling it needs proof of ownership, and a registered residential building contractor can pull it on the owner's behalf. Homes outside city limits should check with their own city or the county.

Will a dry summer make my foundation worse?

It can. Clay shrinks as it dries and swells when rain returns, so a long dry stretch followed by heavy rain is when many slabs move most. 2022 was San Antonio's second driest year on record, at 11.51 inches (NWS Austin/San Antonio).

Can a pier and beam house be leveled?

Yes, and often more easily than a slab, because the work is done from the crawl space. Typical jobs reshim the beams, add supports and replace damaged wood. Fixr prices pier and beam work at $2,000–$15,000 nationally (2026).

Should I hire a structural engineer first?

Worth it before a home purchase, when two bids propose different fixes, or when interior and exterior walls are both cracking. Fixr lists an engineer's report at $300–$2,000 and This Old House at $500–$1,000.
