Planning ranges
| Job | Planning range | Notes |
|---|---|---|
| Mudjacking | $3 – $7 per sq ft | Cement slurry, larger holes, lower cost |
| Polyurethane foam lifting | $5 – $12 per sq ft | Light foam, small holes, use the same day |
| Single sidewalk slab | $300 – $800 | Often a minimum charge applies |
| Patio tipped toward the house | $800 – $2,500 | Plus sealing the joint at the wall |
| Replacement, for comparison | $8 – $18 per sq ft | Tear out, haul away, form and pour new |
These are planning ranges, not quotes. They reflect commonly published figures for US residential projects and what drives them in older St. Louis-area homes. Your price comes in writing after the free inspection and replaces anything on this page.
Lift or replace?
Leveling is usually far cheaper than tearing out and pouring new, and you can use the slab right away or the next day. Replacement wins when the slab is broken into many pieces, scaling badly, or heaved by roots. Lifting a slab that is falling apart only gets you a level slab that is still falling apart.
Do not skip the joints
After lifting, the joints between slabs and against the house are sealed so water cannot wash out the soil again. Skipping that step is how a slab ends up sinking a second time.
Quick answers
Is foam worth the extra cost?
On soft soils and slabs near the foundation, the lighter foam adds less weight. On simple walkways, mudjacking often does the job for less.
How long does a lift take?
Most residential jobs take a few hours.
Can a driveway carry a car right away?
After foam lifting, usually within the hour. After mudjacking, give it a day.
