The honest test is simple. If the slab is solid and the problem is on the surface or in one spot, repair it. If the slab is broken up or the ground under it has failed, replace it. The situations below use the customer's own numbers.
The price ranges on this page are national figures published by HomeGuide for 2026. They are not our quotes and not Sioux Falls averages. Local labor, ready-mix prices, access, tear-out and the soil under your slab move the number. Last checked October 2026.
Is it cheaper to repair or replace concrete?
It is cheaper to repair in the short run nearly every time. Leveling runs $3 to $12 per square foot and resurfacing $3 to $7 nationally, against $6 to $15 for a new driveway plus $3 to $8 for removal. Repair stops being cheaper when you pay for it twice. A slab that keeps heaving on wet clay will need the same repair again.
My driveway is 20 years old and one section has sunk by the garage. I was quoted $9,000 to replace it all. Do I have to?
Probably not. A section that has sunk by the garage is the most common driveway problem in Sioux Falls, and it comes from basement backfill settling, not from the whole driveway failing. If the other panels are level and not flaking, that one section can be lifted or replaced on its own for a fraction of $9,000. Replacing everything makes sense only if the rest is scaled, cracked or heaved as well. Ask the contractor to price the single section so you can compare.
Should I repair for $7,000 or replace for $14,000 if I am selling in two or three years?
With a two or three year horizon, the repair usually wins if it will look good and hold through the winters you have left. You spend $7,000 less, and a buyer mainly wants a driveway that is level and safe. Choose replacement if the repair is likely to fail before you sell, for example an overlay on a slab that heaves, because then you pay $7,000 and still face the $14,000.
I have a few long cracks and I am selling the house. Repair, replace or leave it?
If the cracks are tight and level, seal them and leave the slab. A few long cracks in a driveway are normal here and most inspectors note them without alarm. Clean, sealed cracks look cared for. Replace only if panels are uneven enough to trip on or water runs toward the house. Those are the items a buyer's inspector will write up.
One contractor says remove it, another says pour a new layer over it. Who is right?
In this climate the one who says remove it is usually right. A thin new layer bonded on top of old concrete follows every crack below it and can come loose after a few freeze and thaw seasons. Pouring over old concrete also raises the surface, which causes trouble at the garage door, steps and sidewalk. An overlay is reasonable only on a slab that is level, uncracked and worn just on the surface.
Can you pour new concrete over old concrete?
You can, but it rarely pays here. A full-thickness slab poured over old concrete needs several inches of height that most driveways do not have. A thin bonded topping depends completely on the old slab staying still, and frost does not allow that for long. Taking the old slab out lets us fix the base, which is usually the real problem.
My driveway is 30 years old with root cracks and I am on a tight budget. Can I grind and patch?
Yes, on a tight budget grinding and patching is a fair way to buy time. Grind the raised lips so nobody trips, seal the cracks before winter and replace only the worst panel if one is broken up. Be clear about what it is. The roots will keep growing and frost will keep working, so plan for replacement of that area within some years.
I have many small cracks but no sinking. Is sealing or resurfacing enough?
Sealing or resurfacing is enough when the cracks are fine, the slab is level and the surface is hard. Fine surface cracks are mostly cosmetic. A penetrating sealer keeps water and salt out and slows the wear. Resurfacing gives a new look but the old pattern may show through again. If a screwdriver digs into the surface easily, the concrete is weak and neither will last.
