Selling a San Antonio Home With Foundation Movement: Disclosure, Repairs, and What Buyers Will Ask

San Antonio sits on some of the most expansive clay soil in Texas. If your home has moved — or been repaired — here is exactly what you must disclose, what to fix, and how to price it.

6 min read · September 9, 2026

If your San Antonio home has visible cracks, sticky doors, or a prior pier job, you cannot list it and hope the buyer's inspector misses it. Texas Property Code § 5.008 requires you to disclose known defects on the TREC OP-H Seller's Disclosure Notice, and foundation movement is the single issue Bexar County buyers ask about most aggressively. The good news: houses with documented, warrantied repairs sell every week here. Houses with hidden or half-answered foundation histories die in the option period.

This is the playbook for selling a home that has moved, is moving, or was repaired at some point in its life.

Why San Antonio foundations move in the first place

Most of Bexar County east of I-35 and much of the south and southeast sits on Blackland Prairie clay — high-plasticity soil that swells when wet and shrinks when dry. Cycle that through a Texas summer, a wet fall, and another drought, and you get differential movement under a slab. West and north of the city (Helotes, parts of Boerne, the northern edge of 1604) transitions to caliche and limestone, which is more stable but not immune, especially where builders backfilled over cut-and-fill lots.

Neighborhoods where foundation history comes up constantly:

  • 1950s–1970s slab homes on the near northeast (78209, 78218, 78230) built before modern post-tension standards.
  • Pier-and-beam bungalows in Monte Vista, Beacon Hill, Mahncke Park, and older parts of Alamo Heights.
  • 1990s–2000s tract subdivisions on the south and far northeast where subgrade prep was inconsistent.

Drought years — including the extended dry stretches Bexar County has seen this decade — accelerate movement. A house that sat flat for 20 years can crack a lintel over one bad summer.

What Texas actually requires you to disclose

Texas Property Code § 5.008 requires a written Seller's Disclosure Notice for almost every residential resale of one to four units. TREC's OP-H is the standard form; most listing agents use TAR's longer version, which asks the same questions in more detail. Read the form and answer honestly. The categories that matter here:

  • Structural items: cracks in walls, ceilings, or the slab itself.
  • Previous repairs: any foundation work, leveling, piers, or drainage correction — even if done by a prior owner and even if you have no paperwork.
  • Active claims or lawsuits: including any warranty claim you have opened with a foundation contractor.
  • Known defects: doors that will not latch, brick step-cracks, separated cabinet crown, sloped floors.

"I don't know" is a legitimate answer for things you truly do not know. It is not a shield for things you noticed and ignored. A buyer who later proves you knew and checked "No" is looking at a DTPA claim under Chapter 17 of the Business and Commerce Code, and Texas juries do not love sellers who lied on the OP-H.

If a prior owner did the repair and you have no records, say so on the form and attach whatever you can find — a receipt, an old engineer letter, a photo of piers being installed.

Get an engineer's report before you list, not after

The biggest mistake sellers make with a suspect foundation is waiting for the buyer's inspector to raise it. Once the buyer's inspection report says "recommend evaluation by structural engineer," you have lost control of the narrative and the price.

Before you list, hire a licensed Texas Professional Engineer (P.E.) — not a foundation company salesperson — to evaluate the home. Expect to pay several hundred dollars for a written report with elevation readings (typically a ZipLevel survey showing floor deflection in inches across the slab). The report will say one of three things:

  1. Movement is within tolerance; no repair recommended.
  2. Cosmetic evidence of past movement; monitor.
  3. Repairs recommended, with a scope.

All three outcomes are useful. Option 1 is a document you hand every buyer that shuts the conversation down. Option 3 lets you decide whether to fix it, price it in, or offer a concession — on your timeline, with competing bids from foundation contractors, not under a 7-day option-period gun.

Repair now, or price it in

The two viable strategies:

Repair before listing

Get two or three bids from established San Antonio foundation contractors — Olshan, Ram Jack, and Foundation Support Specialists are the ones most Bexar buyers recognize, and all three issue transferable lifetime warranties on the piers they install. Transferability is the whole point. A warranty that dies at closing is worth almost nothing to your buyer; a transferable one shows up on the OP-H as an asset.

After repair, have the engineer come back for a post-repair letter confirming the work was done to the recommended scope. That letter plus the warranty paperwork is your listing packet.

Price it in and disclose

If you cannot or will not repair, disclose the engineer's findings, attach the report to the MLS, and price accordingly. Bexar buyers are not scared of a disclosed, documented foundation issue with a repair bid attached. They are scared of surprises. A $12,000 pier bid disclosed up front costs you roughly $12,000 in price. The same issue discovered in the option period costs you $12,000 plus a retrade of $5,000–$10,000 on top, plus the risk the buyer walks and you re-list as a house with a "terminated" history on the MLS.

What the buyer's lender and appraiser will do

Conventional and FHA underwriters both flag foundation notes in an appraisal. FHA and VA appraisers are required to call out visible structural defects; the appraisal will come back "subject to" repair or engineer clearance. That means no loan funds until the condition is cleared.

If you are selling to an FHA or VA buyer — a large share of the Bexar market given JBSA-Lackland, Randolph, and Fort Sam Houston — plan for this. An engineer's letter stating the foundation is performing as intended, dated within the last 12 months, usually satisfies the underwriter. Without it, the loan stalls and your closing date slides.

Pricing a home with a repaired foundation

A properly repaired foundation with a transferable warranty and an engineer's post-repair letter does not need to trade at a discount to comparable homes on the same street. It does need to be marketed correctly:

  • Put the warranty and engineer letter in MLS documents.
  • Have your agent mention the transferable warranty in the listing remarks.
  • Be ready to hand a physical folder to buyers at the first showing.

What actually kills price is ambiguity: "foundation was worked on at some point, no paperwork." That reads to a buyer's agent as unknown liability, and they will coach their client to bid low or skip the house.

What most people get wrong

  • Checking "No" on the OP-H because the repair was 15 years ago. The form asks about previous repairs, not current defects. Disclose it. Attach what you have.
  • Using a foundation company's "free inspection" as the diagnostic. That is a sales call, not an engineering opinion. Buyers' agents know this. Pay a P.E.
  • Assuming cosmetic patching hides the problem. Fresh drywall mud over a stair-step crack in a 1978 brick veneer is the first thing a home inspector photographs. It reads as concealment, which is worse than the crack itself.
  • Repairing without an engineer's scope. If the foundation contractor picks the pier locations without an engineer, you have no independent document saying the repair addressed the actual movement. Buyers' engineers will notice.
  • Letting the warranty lapse in your name. Most transferable warranties require the seller to notify the contractor and, in some cases, pay a small transfer fee at closing. Miss that step and the buyer inherits nothing.
  • Confusing cosmetic settlement with active movement. Not every hairline crack is a foundation problem. An engineer's report can tell you the house is fine, which is often the cheapest money you will spend on the sale.

Before you list

Pull any old repair receipts, get a P.E. out to the house, decide repair-versus-disclose with real numbers in hand, and complete the OP-H before your agent puts the sign in the yard. Foundation issues do not tank San Antonio sales. Ambiguity does.
