Slab foundation repair
Piers driven past the active clay to stable ground, then a controlled lift back toward level. This is the core repair for most Texas slab homes, and it's more precise than it might sound: every pier count and depth comes from actual elevation readings, not a guess.
- Free inspection with real elevation readings
- Fixed written price before any work starts
- Strong warranty on every repair we do
What a slab repair actually involves
Elevation survey
We measure the slab room by room with a laser level, mapping exactly where and how far it's dropped. This is what determines pier count and placement, not a walkthrough estimate.
Access points dug
Holes are dug at each pier location around the perimeter, or occasionally the interior, sized to reach the depth the survey calls for.
Piers driven to stable ground
Steel or concrete piers are driven or poured past the active clay layer to soil that doesn't move with the seasons.
Controlled lift
Hydraulic jacks raise the slab back toward level in small, even increments, monitored the whole way so the structure isn't stressed by moving too fast.
Backfill and restore
Access holes are filled and the area is returned to roughly how it looked, minus any landscaping directly on top of a pier location.
Slab repair pricing
Price depends on several things together: how many piers a house needs, how deep they have to go, and how easy the site is to access. These are the ranges most slab jobs fall into.
| Work | Typical range |
|---|---|
| Single pier | $300 to $900 |
| Partial perimeter lift (8 to 12 piers) | $3,500 to $9,000 |
| Full perimeter slab repair | $8,000 to $20,000 |
Ranges vary by region; DFW clay generally runs toward the higher end, Houston-area jobs toward the lower end. Your city page has region-specific numbers. We give you a fixed written price after the inspection either way.
Signs slab repair is likely the right fix
Diagonal cracks from openings
Cracks running from the corners of doors or windows are one of the more reliable signs of real slab movement, especially if they're widening.
Doors that don't return to normal
Seasonal sticking is common and often not serious. Sticking that's been getting steadily worse over a year points to the frame going out of square and staying there.
A floor that visibly slopes
Consistent slope in one direction, checkable with a marble or a level, means the slab has moved unevenly rather than settled uniformly.
A crack wide enough for a coin
Beyond normal concrete shrinkage. This scale of separation also lets water into the structure, which compounds the original problem.
Not sure which of these applies to you? The symptom checker on the homepage walks through this by location in the house and gives an honest read either way.
Common questions
How do I know if I need slab foundation repair?
Common signs include diagonal cracks from door or window corners, doors that stick and don't return to normal, a floor that noticeably slopes, and cracks wide enough to fit a coin. One symptom alone is often nothing; several together are worth an inspection.
How many piers does a typical slab repair need?
It depends entirely on the house and how far the foundation has moved. A partial perimeter lift often uses 8 to 12 piers. A full perimeter job on a larger home can use significantly more. The number comes from elevation readings, not a guess.
Steel piers or concrete piers, which is better?
Steel piers are typically driven deeper and are common where stable soil sits further down. Concrete piers are often used where stable ground is reached at a shallower depth. Both are legitimate methods; which one applies depends on soil depth on your specific lot, not a universal preference.
Will slab repair fix cracks in my walls?
Piering addresses the foundation movement causing the cracks, not the cosmetic cracks themselves. After the slab is leveled, wall and drywall cracks typically still need separate cosmetic repair, which is usually a smaller, separate cost.
Does slab repair damage my landscaping or driveway?
Piers are installed at specific points around the foundation perimeter, so some digging is unavoidable near those spots. A reputable contractor backfills and restores the area afterward, though replacing mature landscaping or extensive hardscaping is usually a separate cost.
