Slab foundation repair cost in Houston

Slab foundation repair in Houston typically costs $3,300 to $6,800 for a standard pier job, based on a 2026 Houston guide. A stable crack in a concrete slab can be sealed for $250 to $800, while a badly settled house that needs lifting across most of the slab can pass $20,000. The spread comes down to how many piers go in, whether any go through the floor inside, and how easy the slab edge is to reach. Below: prices by method, the extras to budget for, and what a new slab costs. For how the work itself is done, see concrete slab foundation repair in Houston.

What is the average cost of slab foundation repair in Houston?

The average Houston slab job falls between $3,300 and $6,800, according to the 2026 Houston Press guide, and most of that money pays for piers. Nationally, This Old House reports a range of $2,224 to $8,134 with an average of $5,179, and says repairs cost about the same for every foundation type except pier and beam and stone. So a slab is neither the cheapest nor the dearest foundation to fix.

These figures are a guide, not a quote. A local foundation contractor gives you the real price in writing after measuring your floor.

What makes a concrete slab foundation repair cost more or less?

Pier count is the biggest driver, then pier type, interior work and access. Each pressed concrete pier adds roughly $300 to $600 in Houston, so a job needing eight piers starts at about $2,400 to $4,800 for the piers alone. Breaking through the floor for interior piers adds about 15%, and awkward access adds 6 to 8% to pier costs.

• How far the slab has moved, and where. One dropped corner needs a short run of piers; a whole side needs a long one. The types of foundation piers and what each costs explains the choice.
• Interior piers. Piers under interior beams mean cutting flooring and concrete inside, then patching.
• Access. Decks, driveways and tight side yards slow the dig.
• The ground. The USDA describes the Lake Charles clay of Fort Bend County as 45 to 60% clay that cracks open in dry spells.

Subsidence matters too. The Harris-Galveston Subsidence District measured the fastest sinking, over 3 cm a year, around Katy and Fulshear, worth raising with a contractor if you own a slab home in Katy.

How much does it cost to fix a slab foundation by repair method?

The method decides most of the bill. Sealing cracks in a stable slab runs $250 to $800. Mudjacking a sunken section of concrete runs $550 to $1,300. A pier job, the usual fix for a settled Houston house, costs $3,300 to $6,800 on a typical home. Lifting a severely settled house can reach $20,000 to $23,000. The cheaper methods only suit a slab that has stopped moving.

Crack sealing suits hairline cracks with no change in floor level, covered in the foundation slab crack repair cost guide. Mudjacking fills voids and lifts small areas; see mudjacking cost. Pressed piers are the standard Houston repair, with steel or helical piers where firm soil is deep.

How much does a 2000 square-foot foundation slab cost?

A new concrete slab costs about $4 to $8 per square foot, according to This Old House's 2026 slab guide, which works out to roughly $8,000 to $16,000 for 2,000 square feet. The same guide puts a monolithic slab foundation at an average of $12,300. The guide doesn't say what its per-square-foot figure includes, so treat it as the concrete work alone.

Repair isn't priced by the square foot. The price comes from how many piers the movement needs, so a 2,000 square-foot house with one settled corner can cost less to fix than a smaller house sinking along a whole side.

Houston has almost no basements: most homes sit on a slab or older pier and beam, so repair is the usual route.

What extra costs come with slab foundation repair?

Plan for a permit, possibly an engineer, and a plumbing check. Permits nationally add $75 to $150, a structural engineer's report $500 to $1,000, and a soil report $500 to $3,000. An inspection in Houston averages about $600. This Old House also suggests keeping $1,000 to $2,500 aside for surprises found once digging starts.

Foundation repair in the City of Houston needs a building permit, and in Bellaire residential foundation work also carries the $130 floodplain permit. See structural engineer foundation inspection cost for when a report is worth paying for.

Lifting a slab can stress the drain lines under it, so a plumbing test before and after is common. A broken line found that way is a separate bill: see concrete slab leak repair cost.

Is it cheaper to repair a slab foundation now or wait?

Repairing early is almost always cheaper. This Old House gives the example of a hairline crack that costs $250 to $800 to seal but can become a $10,000 to $15,000 repair if left until it causes structural damage. On Houston clay, a concrete foundation that has started moving often keeps moving, as dry spells open the ground again.

Watching can make sense for a single crack with no sticking doors or sloping floor: mark its ends, date it and check it. For prices across every kind of foundation, see the foundation repair cost guide for Houston.
