Published national figures put small crack repairs at $100 to $400 and bigger repairs at $600 to $3,000. In this valley the cause is rarely frost. It is usually soil that swells and shrinks, a fill pad settling at its edge, a tree root, or water getting under the slab.
The dollar figures on this page are national ranges that HomeGuide published for 2026. They are not quotes from The Santa Clarita Concrete Company. Labor rates in Los Angeles County, hillside access, pump time and the soil on your lot all shift the real number. Last checked October 2026.
How much does concrete repair cost?
Concrete repair cost depends on the method. Crack filling is published at $0.50 to $3 per linear foot, or $100 to $400 for a driveway's worth. Patching is $3 to $8 per square foot. Major repair or resurfacing of a driveway is $600 to $3,000.
| Method | National published range |
|---|---|
| Crack repair | $0.50 to $3 per linear ft |
| Patching | $3 to $8 per sq ft |
| Resurfacing | $3 to $7 per sq ft |
| Decorative overlay | $6 to $20 per sq ft |
| Leveling | $3 to $12 per sq ft |
Can cracked concrete be repaired or does it have to be replaced?
It can be repaired when the crack is narrow and both sides sit at the same height. Sealing it keeps water and weed roots out. It should be replaced when one side has dropped or lifted, when the crack keeps widening, or when the panel is in several loose pieces. Those are signs the ground moved, and filler does not fix ground.
Why is my concrete driveway cracking?
All concrete shrinks as it dries, so some cracking is normal and joints are there to hide it. Beyond that, the common causes in Santa Clarita are clay-bearing soil that swells in a wet winter and shrinks through the dry months, fill settling near the edge of a graded pad, roots, and heavy vehicles on a 4-inch slab. Earthquakes add to old cracks as well.
Why is my concrete sinking and can it be leveled?
A slab sinks when the soil below it compacts or washes away. Here the usual culprits are a leaking sprinkler or drain line, runoff pouring off a roof with no gutter, and backfill beside the house that was never packed. If the slab is still in one sound piece, it can often be leveled by pumping material under it.
How much does concrete leveling cost?
Concrete leveling cost is published at $3 to $12 per square foot, with a typical job between $700 and $5,000 and a minimum charge of $300 to $700. Mudjacking is listed at $4 to $9 per square foot and foam lifting at $8 to $25.
Mudjacking or polyurethane foam: which is better?
Neither wins every time. Mudjacking pumps a sand and cement slurry, costs less and suits thick outdoor slabs with good access. Foam is light, needs smaller holes and sets in minutes, which suits slabs on weak fill where extra weight is unwelcome. Ask the installer which one they would use on their own house and why.
Is foam lifting a permanent fix or will the slab drop again?
Foam is a permanent fix only if the reason for sinking has stopped. The foam itself does not rot or wash out. But if a pipe still leaks, or a fill slope is still creeping, the soil under the foam keeps moving and the slab follows it. Fix the water first, then lift.
Can concrete be resurfaced instead of replaced?
Yes, when the slab is solid and level and only the top is worn, stained or lightly pitted. Resurfacing is published at $3 to $7 per square foot, or $1,200 to $2,900 for a two-car driveway. It will not hide a moving crack or a tilted panel.
My old patio has cracks and flaking. Can it be resurfaced and how long will that last?
If the cracks are hairline and still, and the flaking is shallow, resurfacing can work. How long it will last depends on preparation and sun. A well-bonded overlay on a stable slab can serve for many years. A thin coat over a dusty or moving slab can peel in a season or two. We would rather tell you it is not a candidate than sell you a coating that fails.
Why is my concrete spalling or flaking?
In cold states the answer is freeze-thaw and road salt. In Santa Clarita spalling or flaking usually traces back to pour day: water added to the surface during finishing, finishing while bleed water was still up, or a slab that dried too fast in heat and wind. In Acton and Agua Dulce, winter freezes can add real frost damage to unsealed slabs.
Can a flaking surface be repaired without replacing the slab?
Often yes. If the flaking is shallow, the weak layer is ground or blasted off and the surface can be repaired with a bonded resurfacer. If you can dig the concrete out with a screwdriver an inch down, the mix was poor all the way through and replacement is the honest answer.
Why is my driveway lifting or heaving?
Lifting or heaving has two main causes here. Tree roots are the first, especially under old oaks, pines and ash trees near the curb. Expansive clay is the second: it swells when soaked and pushes up the middle or edge of a panel. Frost heave is not a factor on the valley floor.
Will a patch hold in a wide crack or will it pop out?
A patch in a wide crack holds if the crack is cut clean, the slab on both sides is still, and a flexible or bonded repair material is used. A patch pops out when the two sides are still moving against each other, or when cement was simply troweled into a dirty gap.
How do I fix a sunken walkway that is a trip hazard?
There are three ways to deal with a trip hazard. Lift the low panel, grind the high edge, or replace the panel. Lifting suits a sound panel over a void. Replacement suits a broken one. If the walk is the public sidewalk, an encroachment permit is needed before work starts.
