Concrete Leveling in McKinney, TX

Concrete leveling McKinney homeowners ask about is usually for a driveway, patio, sidewalk, pool deck or garage floor that has sunk on one side, not for the house foundation itself. Concrete leveling raises a slab that has dropped by pumping material through small holes into the void underneath it. Two materials do the job: a sand and cement slurry (mudjacking, sometimes called slab jacking) and expanding polyurethane foam. Both lift the slab back to grade in a single visit without tearing it out and pouring new concrete, which is what makes leveling worth a look before replacement.

The free inspection measures how far the slab has dropped, finds the void with a few test probes, and looks for the reason the soil left. You get a written estimate before the visit ends. Call (972) 555-0100 for same-week scheduling. Requests are routed to an insured local contractor working across Collin County, and calls may be recorded for quality.

Signs you need concrete leveling in McKinney

Sunken concrete is easy to spot once you know where to look. These are the usual signs:

• A lip at the joint between the driveway and the garage floor, or between two driveway sections, that catches a toe or a tire.
• A patio or walkway that now slopes toward the house, sending rainwater against the slab edge instead of away from it.
• Water pooling on a driveway or patio after rain in a spot that used to drain.
• A hollow sound when you tap the slab with a broom handle, which means the soil under it has washed out or shrunk away.
• A visible gap under the edge of a slab, or a step that has pulled away from the porch it once met.
• Sidewalk panels that have tilted, leaving a trip edge along a path to the front door.
• An interior floor, often in a garage or a slab addition, that has dropped between the house piers and left a gap under the baseboard.

A slab that has dropped less than an inch and stopped is a leveling job. A slab that keeps dropping, or a house perimeter that is settling into the clay, needs the pier work described on the slab foundation repair page, and the inspection will say which you have.

What concrete leveling involves in McKinney

The soil is why so many McKinney slabs sink. The USDA NRCS fact sheet for the Houston Black series, the Texas state soil that covers the Blackland Prairie from north of Dallas to San Antonio, calls it the classic Vertisol that shrinks and swells markedly with changes in moisture, and notes that its very high shrink-swell potential is a common limitation for building sites in metropolitan areas. The NRCS Official Series Description puts its clay content at 40 to 60 percent and describes cracks 1/2 to 4 inches wide opening at 12 inches deep during dry periods. National Weather Service Fort Worth normals put DFW’s wettest month, May, at 4.78 inches of rain and its driest, July, at 2.08 inches, and the same office recorded just 1.25 inches for the whole summer of 2023. A patio slab poured on that clay loses its support every dry summer and gets it back, unevenly, every wet spring.

Day one is the whole job on most leveling work. The crew starts by marking the low points with a level and a string line, then drills a pattern of holes through the slab. For foam, the holes are about five eighths of an inch across, spaced a few feet apart. For mudjacking, the holes are closer to an inch and a half or two inches. A port is set in each hole and the material is pumped in.

• Mudjacking slurry is a mix of sand, cement and water pumped under pressure. It fills the void from the far side toward the port and lifts the slab as it packs in. It is heavy, so it is used on thick slabs and where the added weight will not matter.
• Polyurethane foam is a two-part liquid that expands to many times its volume within seconds of mixing. It reaches into small voids, weighs a fraction of slurry, and takes load within about an hour. It is the usual choice for driveways, pool decks and any slab where the soil below is already soft.

The crew watches the slab rise with a level and stops the moment it meets the neighboring section. Holes are patched with a grout matched to the concrete, and the joints are caulked so water stops getting under the edge. Where a downspout or a yard slope caused the washout, the estimate will say so, and foundation drainage fixes the cause so the slab stays put.

On permits, the City of McKinney Building Inspections General Guidelines for Foundation Repair require a permit for any foundation leveling, pier or footing replacement, shimming or floor system replacement. A detached driveway, walk or patio is not the house foundation, but an interior floor is, so lifting a floor inside the house falls under the city’s permit and engineer’s letter requirement. The contractor confirms with Building Inspections before the work is scheduled and pulls the permit where one is required.

What concrete leveling costs in McKinney

Fixr’s 2025 concrete leveling guide puts the typical job at $500 to $1,700 with a national average of $1,500, and gives a per square foot range of $1.80 to $25 depending on material. HomeAdvisor’s 2026 guide lists mudjacking at $500 to $1,300, This Old House’s 2026 guide puts it at $550 to $1,300, and Modernize’s 2026 guide lists foam injection separately at $900 to $2,500 per job. Foam costs more per square foot, at $20 to $25 in Fixr’s 2025 guide, but it is lighter and cures faster, so the material choice is the main thing that moves the number.

Those are national ranges from named guides, not quotes, and the square footage and drop on your free written estimate are what set the real figure.

Concrete leveling McKinney driveways, patios and garage floors need

Each surface has its own habits, and the estimate is written around them.

Driveways sink most often at the garage joint and at the street apron, where tires load the same spot every day and a downspout or a sprinkler head keeps the edge wet. Fixr’s 2025 guide prices leveling a 600 square foot driveway at $3,000 to $15,000, a wide range because a single dropped section and a whole driveway are very different jobs. Foam is the usual choice because it takes traffic within the hour.

Patios and pool decks tilt toward the house when the backfill against the slab was never compacted. The tell is water pooling at the door or running under the threshold. Fixr’s 2025 guide puts a 200 square foot patio at $360 to $5,000. Leveling pairs with recaulking the joint against the house, because a sealed joint is what keeps the void from coming back.

Garage floors and interior slabs are the case where leveling and foundation work meet. A garage floor is often poured separately from the house slab and can drop on its own, which is a straightforward foam job. A living-area floor that has dropped between the house piers can also be lifted with foam, but that is foundation leveling in the city’s terms, so the permit and engineer’s letter apply. When the drop is part of a perimeter that is still moving, the fix is piers, and the sinking foundation page explains how crews tell the difference.

Sidewalks and steps are small jobs where the point is a safe trip edge, and they are usually added to a driveway or patio visit.

When the sunken concrete is the house itself rather than a flatwork slab, slab foundation repair with piers is the right page, and house leveling covers bringing a whole pier and beam or slab house back to an even floor. Because water is the reason most of these slabs dropped, foundation drainage is the most common companion job. If the perimeter is dropping too, start with the sinking foundation page, and use the foundation repair cost page to see how leveling line items compare with pier work. Crews also cover Allen and Princeton.

The concrete leveling McKinney homeowners get the most from is the kind that fixes the void and the water that made it. Have the slab measured, get the material and the square footage in writing, and ask what will keep it from dropping again.
