Foundation Heaving Repair in Dallas–Fort Worth
Heaving is expansive clay swelling with excess moisture and pushing your slab UP, the opposite of settling. Piers alone can’t fix it. FCS finds the moisture source, stops it, and stabilizes your foundation, starting with a free on-site evaluation.

Upward Movement
What is foundation heaving?
Foundation heaving is when the expansive clay under your home takes on too much water, swells, and pushes the slab up. It’s the opposite of settling: settling is your foundation sinking as dry clay shrinks; heaving is your foundation rising as wet clay expands.
In North Texas the classic pattern is center lift (a “dome”): the slab seals the soil beneath it from evaporation, so moisture accumulates under the middle of the house while the perimeter dries with the seasons. The center rises, the edges don’t, and floors hump, doors bind and slab cracks follow.
The distinction matters because the fix is different. You can’t pier your way out of a heave. The moisture source has to be found and stopped first. That diagnosis is exactly what our free evaluation is for.
Heaving: swelling clay pushes the slab UP while the perimeter stays put.
Where the Water Comes From
What causes foundation heaving in DFW
Heaving always traces back to excess moisture in the clay. In Dallas–Fort Worth, these are the usual suspects:
Under-slab plumbing leak: a supply or sewer line leaking beneath the slab feeds the clay continuously. This is the most common culprit behind a true heave.
Poor drainage: water pooling against the foundation after rain, from bad grading, short downspouts or overwhelmed gutters.
Over-watering: flowerbeds and foundation watering programs that run too heavy on one side of the house.
A large tree removed: a mature tree draws hundreds of gallons a week. Remove it and the soil it kept dry slowly re-wets and swells for years.
Seasonal clay swell: North Texas expansive clay grows and shrinks with every wet-dry cycle; wet years push moisture deep under the slab.
Not sure which one is yours? That’s our job. Call (972) 975-9338. The on-site evaluation is free and we test for the source, not just the symptom.
Know the Signs
Signs your foundation is heaving
Heaving leaves a different fingerprint than settling. The movement points UP, and usually starts in the middle of the house:
Floors bowing or humping upward, often near the center of the home. A ball rolls away from the middle of the room.
Doors sticking at the TOP of the frame, a telltale heave sign. Settling usually binds doors at the bottom.
Cracks in interior floors and walls: slab cracks that open as the center lifts, drywall cracks radiating from door frames.
Raised, cracked or popped tile: tile telegraphs slab movement first. Grout lines crack and tiles lift or “tent”.
A hump you can see or feel: countertops and baseboards pulling out of level toward the middle of the house.
Seeing one or more of these? Don’t wait. An active moisture source keeps feeding the heave until it’s stopped.
Cause First, Not Symptom
How FCS fixes foundation heaving
Moisture management is the fix. We find and remove the water source first, then stabilize and level. Fixing the cause, not just the symptom, is why our repairs hold.
Diagnose the movement
An elevation survey maps exactly what’s high and what’s low, confirming heave vs. settlement, and we investigate the moisture source, including testing for under-slab plumbing leaks.
Stop the water
Our in-house team repairs the under-slab leak or plumbing failure, and corrects drainage and grading so rain and irrigation stop feeding the clay.
Let the clay stabilize
Once the source is gone, swollen clay slowly releases moisture and much of the lift can relax. We monitor elevations honestly instead of selling you work the soil will do for free.
Stabilize & level what remains
Where movement has left parts of the home settled or unstable, we level with engineered piers, backed by our lifetime transferable warranty.
Get the Diagnosis Right
Heaving vs. settling: why it matters
Settling is your foundation sinking as clay dries and shrinks; piers fix it by carrying the home down to stable strata. Heaving is your foundation rising as clay swells, and piers alone can’t push a slab back down against expanding soil. If a company quotes you a pier job without ever asking where the water is coming from, get a second opinion. Ours is free.
Honest Numbers
What heaving repair costs
Heaving repair is priced by the cause, so it varies more than a standard settlement job. The honest ranges:
Drainage or grading correction: often the least expensive fix when pooling water is the source.
Under-slab leak repair: scope depends on where the line failed and how it’s accessed; tunneling costs more than a spot repair.
If piering is also needed: $1,000–$3,500 per pier, the same published range as any FCS pier work.
Typical DFW foundation repairs overall: $3,300–$8,500. Full pricing detail is on our foundation repair cost page.
You get a written, itemized estimate (cause, fix and exact price) before you spend a dollar. Financing is available so an active leak doesn’t have to wait on the budget.
Insurance & Your Policy
Is heaving covered by homeowners insurance?
Seasonal clay swell usually isn’t. Standard Texas policies exclude gradual earth movement, and that includes weather-driven heave.
But heaving is the one foundation problem where coverage is genuinely common: many Texas policies carry a plumbing-leak endorsement (form HO-143TX) that can cover foundation damage caused by an under-slab plumbing leak, and a leak is the most frequent cause of a true heave.
If our testing finds a leak behind your movement, we document the cause honestly, in a straight, defensible report you can put in front of your carrier. We will never invent a plumbing cause to force a claim, and this is educational information, not insurance advice. Confirm coverage with your carrier.

Lifetime transferable warranty: pier work is backed by a warranty that transfers to the next owner. It protects your resale, not just your slab.
Free evaluation, honest report: written findings and an itemized estimate. And if the fix is a $0 sprinkler adjustment, that’s what we’ll tell you.

His approach was to solve the whole problem and not just the symptom… Nate identified an overwhelmed gutter system, undersized downspouts, improper grading… This has caused the soil to hold water and expand resulting in the shifting that prompted me to call. I appreciated the Integrity he displayed.
A few years passed and our cast iron pipes developed a leak, which shifted our home again. Not only did FCS honor their warranty and leveled my home again, I also hired them to replace the cast iron pipes with pvc…they did a great job… I can recommend FCS with confidence!
I was having foundation and plumbing issues for awhile. I interviewed 3 companies and decided on FCS… my house was built in the 1970s and since our soil is mostly clay there was a lot of damage… the crews for both the foundation and plumbing were outstanding.
