Slab Foundation Repair in Dallas–Fort Worth
On DFW’s expansive clay, a concrete slab moves as the soil swells and shrinks: brick cracks, sloping floors, sticking doors. FCS finds the cause, then lifts and stabilizes the slab with the right engineered pier method, backed by a lifetime transferable warranty. The inspection and written estimate are free.

The DFW Slab Problem
Why slab foundations fail on North Texas clay
Most DFW homes sit on a concrete slab poured directly over Blackland Prairie expansive clay, soil that swells when it rains and shrinks hard in a Texas summer. That wet-dry cycle moves the slab season after season, and the house moves with it.
When the soil under one part of the home dries and contracts faster than the rest, that section settles: cracks open over doors, floors slope, brick stair-steps. When trapped moisture makes clay swell and push a slab upward instead, that’s foundation heaving, a different problem with a different fix.
Two accelerants make it worse: under-slab plumbing leaks that quietly soak the clay from below, and poor drainage that lets water pond against the foundation after every storm.
That’s why FCS diagnoses the cause, not just the crack. An elevation survey tells us what is moving and why, before anyone quotes you a pier. Call (972) 975-9338 for a free slab inspection.
Warning Signs
6 signs your slab foundation is moving
Slab settlement announces itself in small ways first, and on expansive clay it does not fix itself. If you recognize two or more of these, it’s time for an elevation survey:
Stair-step cracks in brick: cracks that climb the mortar joints in a staircase pattern are the classic sign one corner of the slab has dropped.
Cracks over doors & windows: diagonal drywall cracks radiating from frame corners show the structure racking as the slab tilts.
Sloping or uneven floors: a floor you can feel lean (or a dropped marble that rolls) means part of the slab has settled out of level.
Sticking doors & windows: frames pushed out of square bind, rub or won’t latch. This is often the first symptom homeowners notice.
Gaps at trim & molding: baseboards, crown and cabinets separating from walls or floors show the slab moving away beneath them.
Cracks in the slab or flooring: cracked tile, buckled wood or a visible crack in the concrete itself. The movement has reached the slab surface.

The Repair
How we repair a slab foundation
One in-house FCS crew handles every step, and because we install every major pier system, the method is matched to your soil and structure, not to a sales script.
Inspect & Survey Elevations
A full inspection plus an elevation survey. We map exactly which parts of the slab have moved, how far, and why, before anything is quoted.
Choose the Right Pier Method
Pressed concrete, drilled concrete, steel, bell-bottom or hybrid: the engineer’s pick for your soil and load, priced in a free written estimate.
Install the Piers
Piers are installed around the perimeter, and through interior breakouts or tunnels where the middle of the slab needs support.
Lift or Stabilize
We lift the settled sections back toward level where the structure allows, or stabilize at current elevation, whichever protects your home best.
Backfill, Clean & Verify
Holes are backfilled, landscaping is restored, and we re-run the elevations to verify the lift before we leave.
Explore the engineered pier methods we install:
Steel and bell-bottom piers cost more but reach deeper, load-bearing strata; pressed concrete costs less and performs beautifully on typical single-story slabs. There is no single best pier, only the best pier for your home, and because we install all of them, our recommendation comes from your elevation survey, not from what we happen to sell.
Slab vs. Pier & Beam
Not sure which foundation you have? FCS repairs both
A slab home sits directly on concrete; a pier-and-beam home has a crawl space under a raised wood floor. The repairs are different crafts: slab work is engineered piering and lifting, while pier-and-beam repair is structural wood work under the house. FCS does both with one in-house crew, so if your home mixes an original raised floor with a slab addition (common across DFW), you get one honest recommendation for the whole structure, not two competing sales pitches. Not sure what you’re standing on? Call (972) 975-9338 and we’ll tell you for free.
Honest Pricing
What slab foundation repair costs in DFW
We publish our ranges, the same numbers our estimators quote in the field:
Most DFW slab repairs: $3,300–$8,500 total, with the average around $5,200.
Priced per pier: $1,000–$3,500 each. Pier count, method and depth set your number, not a flat guess.
Method matters: pressed concrete piers anchor the low end of the range; steel and bell-bottom piers cost more per pier but reach deeper strata.
Free written estimate: you see the exact pier count, method and price before you spend a dollar, and a second opinion on any bid costs nothing.

Fix the Cause, Not Just the Crack
Piers fix the symptom. Water is usually the cause
Lifting a slab without fixing the water that moved it just schedules the next repair. FCS handles both, in-house:
Drainage correction: if water ponds against your foundation after every storm, our drainage correction systems (French drains, surface drains, grading) move it away so the clay stops cycling.
Under-slab plumbing leaks: a slow leak under the slab soaks the clay from below and moves the foundation. Our in-house plumbing team tests for leaks, tunnels to them and fixes them. The same company, one accountable repair.
Heaving from trapped moisture: when swelling clay pushes a slab upward, the fix is moisture control, not piers. See foundation heaving repair.
One inspection covers all of it: foundation, drainage and plumbing. Call (972) 975-9338 to book yours free.

Slab Homeowners on FCS

They installed 12 reinforced concrete piers on my 1990 slab foundation, and the entire process was smooth from start to finish… They took the time to explain everything, answered all my questions, and made me feel confident in the work being done. On top of that, their pricing was very affordable compared to other estimates I received.
TJ was very thorough and honest reviewing our slab foundation. After providing a free foundation evaluation, he advised our slab was fine. We did review our corner pops and scheduled an appointment to have repaired… We are very pleased with FCS and would recommend this company.
Majority of my 32 pier holes were dug from outside; however, I had 4 pier holes that were excavated inside of home. The crew was meticulous… Now, my home is within spec levels and most of the foundation cracks closed in. I’d highly recommend FCS for your foundation repair work. They’re honest, experienced, and do the job right!
