How much does concrete leveling cost in 2026?

What the price data says

We pulled concrete leveling prices from three separate datasets. Each one collects its own estimates, so where they agree, you can trust the range more.

A note on independence: Angi, HomeAdvisor and This Old House share one dataset. This Old House states its estimates are "based on cost data from Angi"^[6]. We count all three as one source, not three. HomeGuide and Fixr are separate datasets.

Method	HomeGuide (Nov 2025)	Angi (2026)	Fixr (Jan 2025)
Mudjacking (cement slurry)	$4 to $9 per sq ft[2]	not separated	$3 to $17 per sq ft for slab jacking[5]
Polyurethane foam (polyjacking)	$8 to $25 per sq ft[3]	$5 to $25 per sq ft, $15 average[4]	$20 to $25 per sq ft[5]
Stone slurry grout	$6 to $15 per sq ft[1]	not listed	not listed
Sandjacking	not listed	not listed	$3 to $7 per sq ft[5]
Typical total	$700 to $5,000[1]	not listed	$500 to $1,700 for a 100 sq ft patio[5]

Two patterns hold across all three sources. Foam costs more than cement slurry per square foot, often about double. And the spread is wide: the low end of foam overlaps the high end of mudjacking.

This Old House, using Angi data, lists slab jacking at $550 to $1,300 per job^[6]. That is a per-job figure, not per square foot, so do not compare it directly with the table.

The minimum fee matters more than the square foot price on small jobs

Most leveling contractors charge a minimum job fee of $300 to $700 or more^[1]. If you have one sunken sidewalk square, that minimum is probably your price. If you have a sidewalk square, a step and a patio corner, ask for one visit to cover all three. One setup costs less than three.

Prices by surface

HomeGuide's November 2025 table is the most detailed by-surface breakdown we found^[1]. These are installed price ranges for typical sizes.

Surface (typical size)	Mudjacking	Polyjacking	Stone slurry grout
Steps (40 sq ft)	$300 to $700	$320 to $1,000	$240 to $600
Sidewalk (100 sq ft)	$400 to $900	$800 to $2,500	$600 to $1,500
Patio or porch (150 sq ft)	$600 to $1,400	$1,200 to $3,800	$900 to $2,300
Partial garage floor (125 sq ft)	$500 to $1,100	$1,000 to $3,100	$750 to $1,900
Garage floor (360 sq ft)	$1,400 to $3,200	$2,900 to $9,000	$2,200 to $5,400
Pool deck (400 sq ft)	$1,600 to $3,600	$3,200 to $10,000	$2,400 to $6,000
Partial driveway (200 sq ft)	$800 to $1,800	$1,600 to $5,000	$1,200 to $3,000
Driveway (450 sq ft)	$1,800 to $4,100	$3,600 to $11,300	$2,700 to $6,800

Source: HomeGuide concrete leveling cost guide^[1]. HomeGuide's own mudjacking page lists steps at $300 to $500^[2], so even one dataset varies a little between pages. Treat every number here as a range, not a quote.

For which method fits which surface, see leveling by surface.

Why prices vary so much by region

National averages hide large local differences. The main drivers:

• Labor rates. Labor is 40% to 60% of a foam jacking job, and crews charge about $50 to $150 per hour depending on location^[3].
• Soil. Soft fill, eroded voids and clay that swells and shrinks all take more material. A void washed out by a downspout can take far more fill than the slab size suggests.
• Access. A pool deck or a backyard patio behind a fence costs more than a front sidewalk.
• Permits. Most flatwork leveling does not need a permit, but HomeGuide notes some cities charge $50 to $200^[3]. Check with your city.
• Add-ons. Crack sealing ($50 to $800+ per crack), joint sealing and drainage fixes ($500 to $2,000+) are often quoted on the same job^[3].

What the price does not buy

Leveling lifts a slab back into place. It does not fix why it sank. The Foundation Performance Association notes that both mudjacking and foam are shallow repairs, so both can move again if the soil moisture under them changes^[7]. If the cause was a downspout dumping water at the slab edge, fix the downspout first, or you may pay again.

Be careful with lifespan claims in sales pitches. Some foam sellers say mudjacking lasts only 1 to 5 years. We found no study behind that number. HomeGuide says properly done mudjacking lasts 5 to 10 years or longer^[2]. See mudjacking vs polyjacking for the full comparison.

Leveling a house slab is a different job

The prices above are for driveways, walks, patios and garage floors. Lifting a house foundation slab is a structural repair. Price it on the slab foundation repair cost page, and have a structural engineer decide whether foam, grout or piers fit your house.

How to compare quotes

• Get the price per square foot and the minimum fee in writing.
• Ask how many injection holes, how big they are, and how they will be patched.
• Ask what happens if the slab cracks during the lift.
• Ask what the warranty covers and what voids it, such as drainage you have not fixed.

When to call a pro

• Any slab that is a trip hazard at a step, walk or entry.
• A slab that sank after a heavy rain or near a downspout, since a hidden void may be growing.
• A garage floor or slab tied to the house, where a structural engineer should rule out foundation movement first.
• Concrete that is badly broken, where a contractor in your area can tell you if replacement is the better buy.
