Do this now, before you call a Houston foundation company

1. Measure and photograph the crack with a date. HomeGuide treats cracks under 1/8 inch as often cosmetic and flags cracks wider than 1/8 inch; put a pencil mark at each end so you can see whether it grows. The ASCE Texas Section guideline says the majority of cracks do not compromise structural integrity, so the record matters more than the first look.
2. Walk the outside after a rain. The ASCE Texas Section guideline calls for grading that falls at least 5 percent for the first 5 feet from the wall and downspouts that discharge well away from it. Pooling water, a short downspout or a flat bed against the house explains a lot of movement.
3. Note doors, floors and the crack pattern. Doors that stick, gaps over cabinets and a floor you can feel slope are the signs HomeGuide lists; the guideline says a floor slope over 1 percent is usually noticeable. Diagonal cracks at corners that are wider at one end are the settlement pattern engineers look for (Forcon).
4. Find out whether you are in a mapped flood zone. Houston's foundation repair permit asks for extra paperwork in zones A, AO, AE, A1-30 and A99: a sealed itemized cost estimate from a Texas-licensed engineer or architect, or a notarized foundation contract, plus an appraisal. Knowing the zone before the first visit saves a week.
5. Decide who inspects first. A foundation repair company's visit is often free; a structural engineer's report costs $300 to $1,000 (Angi) and comes with no repair to sell. HomeGuide warns that companies offering free inspections "may be more likely to recommend repairs to get your business." Foundation inspection cost explains the difference.
6. If there is standing water, keep clear of outlets and equipment. Do not touch electrical equipment if it is wet or you are standing in water (Red Cross). A gas smell with any of this: leave, then call 911 or the gas utility from outside.

Is it urgent? Foundation signs in Houston that should not wait

Most foundation movement in Houston is measured in months, and the ASCE Texas Section guideline says the majority of cracks do not compromise structural integrity. Three things are worth a prompt call rather than a wait-and-see, and none of them is a verdict on your house: a wall that is visibly leaning or has shifted since you last looked; a new horizontal crack at mid-height with the wall bowing inward, which Forcon's engineering guide calls "a cause for immediate concern" because it comes from soil pressure; and plumbing that has stopped draining under a slab, which can mean a broken line washing out the soil beneath it. After a flood, the order changes: do not re-enter standing water with power on (Red Cross), call your insurer, and photograph the slab and walls before anything is cleaned; water damage restoration in Houston covers that sequence.

Everything else, a hairline crack, a door that started sticking this summer, a slope you noticed with a marble, is a measured problem. Photograph it, mark it and book an inspection within a few weeks. HomeGuide prices a single crack injection at $250 to $800 nationally; settling that calls for piers runs $4,500 to $20,000, and the first visit is usually an inspection with a written plan, not a repair.

Houston's foundation repair permit: engineer's plans and the flood zone rule

The Houston Permitting Center lists foundation repair as its own permit (HPWFMO1010) with plan review and inspection required and payment before construction. The permit covers slab fracture repair and "stabilizing structures that have shifted," and the city says engineered piles or piers should be shown on the drawings. For slab-on-grade work it asks for foundation plans by a Texas-licensed engineer showing the location, quantity and type of supports, with the address and owner's name on the sheet. In flood zones A, AO, AE, A1-30 or A99 the application also needs a sealed itemized cost estimate from a Texas-licensed engineer or architect, or a notarized foundation contract, plus a county or private appraisal, and an elevation certificate if the floodplain reviewer asks. The administrative fee is $33.56, the permit and plan review fees follow the city fee schedule, processing runs 1 to 5 business days, and the permit is valid 180 days. A pre-construction inspection requires the approved plans and permit on site, so a crew that starts without them is working outside the permit.

Gulf Coast clay and sinking ground

Houston's soils are Gulf Coast clays rather than the Blackland Prairie clay of Dallas and Austin (the NRCS does not list Houston inside that prairie), and they move for two reasons. The first is shrink-swell: the Harris County soil survey's dwellings table rates Aris soils "very limited" for houses without basements with shrink-swell as the full limiting factor, Clodine very limited with shrink-swell at half weight and Atasco somewhat limited; Angi's Houston page describes the same thing from the plumber's side, expansive clay that swells when wet and shrinks when dry, stressing lines under the slab. The second is subsidence. The Harris-Galveston Subsidence District was created by the Texas Legislature in 1975 to regulate groundwater withdrawal in Harris and Galveston counties because, in the District's words, "groundwater withdrawals have led to subsidence, or the land sinking," and it publishes subsidence rates each spring in an Annual Groundwater Report with maps of 2021 to 2025 rates.

For a homeowner the practical split is this: shrink-swell moves one side of a house against the other and shows up as diagonal cracks and sticking doors; regional subsidence is measured across whole neighborhoods, which is why the District maps it rather than one house at a time. A foundation contractor would check the crack pattern, measure elevations across the slab, test the plumbing for a leak under the slab, and look at drainage and trees on the moved side. Houston's median home was built in 1982, and about 47 percent of its 1,040,576 units date to 1979 or earlier, so the plumbing test matters: slab leak repair explains it.

No Texas license, so the engineer is the check

Texas has no state license for foundation repair. A 2011 bill that would have created one, S.B. 1399, said at the time that "there is no state regulation in place to directly mitigate these risks" and noted "increasing numbers of predatory practices by underfunded but opportunistic repair companies"; it did not become law, and the Texas Department of Licensing and Regulation's list of 41 regulated industries still has no foundation repair or general contractor program. What Texas does regulate is the engineer: the ASCE Texas Section guideline says "the evaluation and repair design shall be performed by a professional engineer licensed in the State of Texas," that the engineer of record has approval authority over changes, and that Texas rules prohibit plan stamping. So the two questions to ask any company are whether a Texas-licensed engineer designs and signs the plan, and what the warranty covers if the house moves again. Ask for proof of insurance either way. In Houston the permit itself enforces the engineer half of that: the plans the city reviews have to come from a Texas-licensed engineer.
