Leveling a sunken concrete slab costs a national average of $1,241, with most homeowners paying $662 to $1,883, per Angi’s 2026 data based on 2,631 verified projects.1 HomeAdvisor publishes the same average and range; Bob Vila’s lower figures ($1,174 average, $630 to $1,723) are published in 2023 and attributed to Angi and HomeAdvisor — matching figures alone don’t establish independent corroboration.2,5 Fixr puts the national average at $1,500 with an average range of $500 to $1,700 — published figures that differ and are not reconciled by the sources.3 Figures below are the latest published national figures* from each source.

Angi and HomeAdvisor are corporate siblings and publish the same average and range, and Bob Vila’s headline is attributed to them — matching figures alone don’t establish independent corroboration.1,2,5 HomeAdvisor’s own overview box shows a slightly different $661 to $1,868 range and about $1,230 average alongside its body’s $662 to $1,883 and $1,241, near-identical figures the page does not reconcile.2 Fixr’s higher average but lower range top ($1,700 versus $1,883) stands apart unreconciled.3
Cost by leveling method
| Method (per sq. ft.) | Angi | HomeAdvisor | Fixr | HomeGuide | Bob Vila |
|---|---|---|---|---|---|
| Self-leveling compound | $1 – $5 | $1 – $5 (excl. labor) | $1.80 – $5 | $2 – $5 | $1 – $5 |
| Mudjacking | $3 – $6 | $3 – $6 | $3 – $25 umbrella | $4 – $9 | $3 – $6 |
| Sandjacking | $3 – $8 | $3 – $8 | $3 – $7 | — | $3 – $8 |
| Slabjacking | $3 – $20 | — | $3 – $17 | — | $3 – $6 |
| Polyurethane foam (polyjacking) | $5 – $25 | $5 – $25 | $20 – $25 | $8 – $25 | $5 – $25 |
| Foundation jacking | — | $3 – $6 mudjack; $6 – $25 foam | $5 – $8 | — | $5 – $8 |
| Stone slurry grout | — | — | — | $6 – $15 | — |
The per-foot figures genuinely differ by source: HomeGuide’s mudjacking range ($4 to $9) sits above the $3 to $6 published by Angi, HomeAdvisor, and Bob Vila, and Fixr uses “mudjacking” as an umbrella term spanning $3 to $25 that it then breaks into sandjacking, slab jacking, foundation jacking, and poly leveling — differing definitions reported as published, not reconciled by the sources.1,2,3,4,5 Angi calls the leveling method the single biggest cost driver and puts the overall average at $4 per square foot with a $150 minimum trip fee.1 HomeGuide puts labor at $50 to $150 per hour; Fixr gives a typical labor figure of about $350 for the average job.3,4
Cost by project
| Project | HomeAdvisor | Fixr | Bob Vila |
|---|---|---|---|
| Sidewalk, 100 sq. ft. | $320 – $650 mudjack; $650 – $2,700 foam | — | $300 – $600 (any method) |
| Patio / floor, 200 sq. ft. | $650 – $4,300 mudjack (interior floor) | $360 – $5,000 | $400 – $1,200 |
| Partial driveway, 200 sq. ft. | $650 – $1,300 mudjack; $1,500 – $3,200 foam | — | — |
| Full driveway, 450 sq. ft. | $1,500 – $3,000 mudjack; $3,200 – $7,500 foam | — | — |
| Driveway, 600 sq. ft. | — | $3,000 – $15,000 | — |
| Garage floor | section $550 – $1,100; full 2-car $1,250 – $2,700 mudjack | — | $1,100 – $2,200 |
| Stairs | $450 – $950 foam | — | — |
| Foundation, 1,500 sq. ft. | $4,800 – $9,000 mudjack; $9,000 – $39,000 foam | — | up to $37,500 |
| Subfloor / basement, 600 sq. ft. | — | $1,080 – $15,000 | up to $4,000 subfloor |
Bob Vila’s garage floor figure ($1,100 to $2,200) and HomeAdvisor’s full 2-car mudjacking range ($1,250 to $2,700) are near-compatible ranges reported as published; Fixr ties its wide driveway span to the method used and the severity of the situation.2,3,5 By city, Bob Vila lists leveling at $870 in Dallas, $830 in Kansas City, $1,360 in Tampa, $1,500 in Los Angeles, $1,800 in Seattle, and $2,500 in New York City.5
Leveling versus replacement
Every source frames leveling as the cheaper first option: Angi averages $4 per square foot for leveling against $10 for replacement (climbing to $100 or more for foundation work), HomeAdvisor says mudjacking runs 25% to 50% less than replacing the slab, and HomeGuide prices replacement at $6 to $15 per square foot.1,2,4 Fixr estimates a 200-square-foot slab replacement at $2,000 or more plus demolition, near $3,000 total, and Bob Vila puts demolition around $1,000 with concrete at $100 to $200 per yard.3,5 Where surfaces need finishing after a lift, Angi budgets $150 to $500 for flooring repairs and $100 to $500 to restore a finished floor.1
DIY versus hiring a pro
Self-leveling compound is the DIY-feasible method: Bob Vila prices DIY self-leveling at $1 to $5 per square foot plus tool rental, HomeAdvisor lists the material at $1 to $5 per square foot excluding labor, and HomeGuide calls it the most affordable option and popular for DIY.2,4,5 Fixr lists material unit pricing: about $10 for a 20 lb. patch, $10 for a 9 oz. filler tube, and $35 per 50 lb. bag for overlay or self-leveling foam compound, with brand-level per-foot prices from $1 to $6 (Param 5500, Ardex, Gypcrete, RapidSet, Quikrete).3 Mudjacking and foam lifting pump material beneath the slab through drilled holes and need professional equipment, and core drilling where required averages $11 per square foot per both Fixr and Bob Vila — another exact match reported factually.3,5 Self-leveling underlayment and patch products are stocked at Home Depot’s Floor Levelers category, where unit pricing can be compared against Fixr’s figures above.
