Quick Answer
- Sidewalk and stoop work is driven by trip hazards, drainage, panel condition, public-walk rules, and safe transitions.
- Intact settled panels may be lifted; cracked, scaled, or heaved panels usually need replacement.
- Lead walks and stoops need safe rise, door clearance, and positive drainage away from the entry.

Mudjacking and Polyjacking Prices in 2026
- Concrete leveling cost runs roughly $3 to $12 per square foot, or $500-$1,500 for typical residential jobs - about 25-50% of replacement cost.
- Mudjacking (slurry) prices lower per job; polyjacking (foam) costs more but lifts cleaner and lasts longer in clay soil.
- Leveling fits sunken-but-intact slabs only; cracked-through slabs need replacement.
Concrete leveling costs about $3 to $12 per square foot depending on method and void size, which makes lifting a sunken slab roughly a quarter to half the cost of tearing out and repouring the same section.
Mudjacking vs Polyjacking Price Difference
Mudjacking pumps a sand-cement slurry through 1.5-2 inch holes at the lower price point; polyjacking injects expanding polyurethane foam through 5/8-inch holes at a 20-40% premium. Foam wins in Chicagoland clay for three reasons the slurry can't match: it's lighter (doesn't re-compress the soil that sank the slab), it cures in minutes instead of a day, and the small holes patch nearly invisibly. The practical split is simple: pay the foam premium on driveways and garage floors; mudjacking remains fine for walks and patios.
Project Totals by Slab Type
| Project | Typical cost |
|---|---|
| Sidewalk section (1-3 panels) | $300-$700 |
| Patio | $500-$1,200 |
| Driveway section | $600-$1,500 |
| Garage floor | $700-$2,000 |
Minimum-job pricing applies - the pump truck costs the same to mobilize for one panel as five, so bundling sunken sections cuts the per-panel price.
Leveling Beats Replacement Only When the Slab Is Sound
Leveling fits slabs that sank intact: settled garage floors, tilted patio sections, sunken walk panels, driveway slabs dropped at the apron. It does not fit slabs cracked into pieces, spalled past refinishing, or sitting on washout that hasn't been fixed - lifting a slab over an active washout is paying twice. The honest decision rule: sound slab + settled base = level it; broken slab or unsolved water problem = replace and fix the cause.
Sunken Slabs Usually Start With Chicagoland's Clay Problem
NW-suburb slabs sink because clay shrinks in drought and washes at downspouts. Whatever the lift method, the quote should name the cause and the fix - downspout extensions, joint caulking, grading - or the slab returns to where it was within a few seasons.
When Leveling Is a Bad Buy
Leveling is a bad buy when the slab is cracked into separate pieces, the surface is badly scaled, the void is still being washed out, or the concrete is too thin to lift cleanly. In those cases replacement costs more up front but prevents paying once for the lift and again for the tear-out.
What the Quote Should Diagnose
A leveling quote should name the lift method, hole size, expected height correction, likely cause of settlement, and any after-work fixes such as joint caulk, downspout extensions, or grading. Lifting the panel without correcting the water path is usually a temporary repair.

Common Questions Before You Call
What does lifting usually cost?
Most residential lifting jobs fall between $500 and $1,700, with mud slurry near the low end and structural foam higher. A sidewalk panel can be a minimum-charge job; a driveway bay, garage floor edge, or patio section costs more because void size, access holes, and controlled lift time increase.
When is lifting better than replacement?
Lifting is the right move when the slab is mostly intact, the surface still looks acceptable, and the issue is settlement. Replacement is the right move when the concrete is broken into pieces, heavily scaled, too thin, or still losing base material to an active water path.
What causes the slab to sink again?
Water is usually the repeat offender. Downspouts dumping beside the slab, open joints, negative grade, and clay soil movement can recreate the void. A good quote explains the lift method and the water fix, because injection alone does not solve drainage.
How should bids be compared?
Compare the total price against the written method, base or drainage correction, thickness where relevant, disposal, access limits, cure timing, and what is included. The better bid is the one that names the work that prevents failure, not the one with the lowest unexplained budget number.
