Here is what this work actually runs in Lexington. We would rather put real numbers in front of you than make you ring round for three quotes to find out.
| What the job involves | Lexington price range per square foot of slab lifted |
|---|---|
| Mudjacking, straightforward slab | $3 – $6 |
| Polyurethane foam, straightforward slab | $5 – $15 |
| Foam, deep settlement or large void | $10 – $25 |
Mudjacking runs about $3 to $6 per square foot; polyurethane foam $5 to $25, and can reach roughly four times mudjacking at the top of the range. Foam is lighter, cures in minutes, and uses smaller holes; mudjacking is cheaper and uses heavier material. Small single-slab jobs usually carry a minimum charge that dominates the per-foot figure.
The dominant variable. Foam costs substantially more per square foot but is lighter, sets in minutes, uses smaller ports and does not add significant weight to already weak soil.
How far the slab has dropped and how much empty space is underneath determines material consumed. A slab that has sunk two inches over a large area is a very different quantity from a corner that has dipped.
A reinforced garage floor or driveway behaves differently from a thin patio or walkway. Thicker slabs resist cracking during lift but need more injection points.
Mobilising equipment for a single sunken step or one panel means the job is priced near a minimum rather than by area. Combining several areas into one visit is markedly better value.
If a leaking pipe or an eroding downspout line is the cause, fixing it is a separate cost and a necessary one. Lifting over an unresolved cause buys a season or two.
Equipment needs to reach the slab. Rear patios behind narrow gates, interior floors, and slabs in confined spaces all add handling time and sometimes different equipment.
When one quote comes in far under the others, it is worth asking what has been left out. Usually it is the preparation — and that is the part that decides whether the work lasts or fails early.
Those are the questions we would ask if we were hiring someone, so ask them of us too. We will answer all of them in writing.
