Foundation Repair Cost in Houston, TX (2026)
Short answer: Foundation repair cost in Houston averages about $5,003, and most quotes run $3,276 to $6,729 [1]; another 2026 guide puts most jobs at $3,500 to $10,000 [2]. Permitted pier jobs in city records are bigger: a $13,000 median [3].
Houston sits on the Beaumont Formation, a band of clay-rich coastal soil that swells when wet and shrinks when dry [7]. University of Houston researchers measured about 4 to 8 inches (one to two decimeters) of ground drop in expansive soil during the summer droughts of 2018, 2020, 2022 and 2023, with roughly 10% of it permanent [7]. That shrink-swell cycle is why slab foundations here move. This guide covers Houston prices from three kinds of sources, plus the city's own permit rules. For statewide per-pier prices, see our Texas foundation repair cost guide.
Houston foundation repair prices
| Job | Typical cost in Houston |
|---|---|
| Average repair | $5,003; most pay $3,276–$6,729 [1]. Another guide: most jobs $3,500–$10,000, about $5,000 average [2] |
| Permitted foundation repair (city permit values) | $13,000 median; middle half $6,277–$24,502 [3] |
| Piering / stabilizing | $2,100–$7,700 [1]; 5–10 piers $2,500–$5,000, 15–20 piers $5,000–$10,000 [2] |
| Large settlement jobs | $9,000–$28,000 for differential settlement [1]; 25–35 piers $10,000–$18,000 [2] |
| Crack repair | $600–$3,200 [1]; $250–$800 for 1–3 minor cracks [2] |
| Slab leveling (slabjacking) | $1,100–$3,100 [1]; $500–$2,500 [2] |
| Drainage fixes | $1,000–$12,000 [1]; French drain $2,500–$6,000 [2] |
| Structural engineer foundation inspection | $400–$1,000 [4][2] |
Why the numbers differ. Angi's figures come from its own cost research and customer data [1]. The $13,000 median comes from values contractors declared on 8,196 City of Houston permits filed from January 2019 to June 2026 [3]. Houston requires engineered pile plans for pier work [5], so permit data leans toward full pier jobs, while survey averages also include small crack and leveling work. Use the first rows for small repairs and the permit median for a full perimeter pier job.
Per-pier prices
| Pier type | Houston price per pier |
|---|---|
| Pressed concrete piers | $400–$500 [2]; $300–$800 Texas-wide [8] |
| Steel push piers | $650–$1,500 [2]; $1,200–$2,500 Texas-wide [8] |
| Interior piers (tunneling under the slab) | $1,000–$2,000 each [2] |
A typical 2,000 sq ft Houston home that needs a full perimeter repair may take 20 to 30 piers [2], which is why the pier count drives the bill.
What moves the price
- Pier count and type. The biggest variable, per both Houston guides [1][2].
- Plumbing under the slab. Movement can crack pipes; a slab leak repair adds $500–$6,000 [2]. See our slab leak repair cost guide.
- Trees and drainage. Root barriers run $1,000–$3,000 [2], and poor drainage can make one side settle [2].
- Floodplain lots. Extra city review and paperwork apply in flood zones [6].
Houston permit notes
- The City of Houston lists foundation repair as a project type that needs structural and flood review. You need a foundation plan showing the number and location of every pile, sealed by a licensed engineer. Block-and-base (pier and beam) repairs can use the city's Repair Per Spec List, Form CE-1059 [5].
- If the home is in a flood zone (A, AO, AE, A1-30 or A99), the city also wants a sealed cost estimate or a signed, notarized foundation contract, plus a county or private appraisal. The floodplain permit carries a $33.56 admin fee, is valid 180 days, and lists 1–5 business days to process [6].
- Ask your contractor to pull the permit and show it to you. Outside city limits, check with your own city or Harris, Fort Bend or Montgomery County.
Steps before you sign
- Get an engineer's report from someone who doesn't sell repairs, about $400–$1,000 in Houston [4].
- Get at least three written bids; Houston quotes for the same home can differ by $3,000–$8,000 [2].
- Compare pier type, pier count, interior vs exterior piers, and what the warranty covers.
- Confirm who handles the city permit and flood review [5][6]. Not sure a crack matters? Read foundation cracks in Texas: when to worry.
