Concrete Driveway Repair Cost Calculator

Concrete driveway repair typically runs $300 to $3,000+, or roughly $3 to $15 per square foot of the repaired area, depending on the type and extent. Simple crack sealing is cheapest (often a few hundred dollars), resurfacing or an overlay to refresh a worn surface is mid-range, slab leveling (mudjacking/polyjacking) to lift settled sections is mid-range, spall/surface patching costs more, and removing and replacing damaged sections is the most expensive (approaching the cost of new concrete for that area). The drivers are the repair type, the damage severity (minor cracks vs. severe, widespread deterioration), the area being repaired, and site access (tight or sloped driveways cost more). Most repair companies have a minimum service charge, so small jobs won't go below it. Repairing is generally far cheaper than fully replacing a driveway, so it's worth doing when the damage is repairable. Enter your area, repair type, severity, and access in the calculator to anchor the estimate.

Each damage type has a matching repair. Cracks (from shrinkage, settling, tree roots, freeze-thaw, or heavy loads) are routed out and filled with a flexible crack filler or patch — wide or structural cracks signal deeper issues. Spalling and scaling (the surface flaking, chipping, or pitting, often from freeze-thaw, de-icing salts, or a poor original finish) is repaired by patching the surface or, for widespread cases, resurfacing. Settling/sinking (sections that have dropped from soil erosion, poor compaction, or voids underneath) is corrected by slab leveling — mudjacking or polyjacking to lift the slab back to level, far cheaper than replacement. A worn-but-sound surface can be refreshed with resurfacing/an overlay (a thin new layer over the old). Heaving (sections pushed up by roots or frost) and severe, widespread damage or a failed base usually require cutting out and replacing sections. Matching the repair to the damage — and addressing the cause (drainage, base, roots) — is what makes the fix last. The calculator lets you pick crack sealing, resurfacing, slab leveling, spall patching, or section replacement.

It depends on how extensive and how structural the damage is. Repair makes sense when the damage is localized (some cracks, isolated spalling, a few settled sections, or a worn-but-sound surface) and the underlying base/structure is still solid — crack sealing, patching, resurfacing, or slab leveling cost a fraction of replacement and add years of life. Replace when the damage is severe and widespread (extensive deep cracking, large crumbling areas, multiple settled or heaved sections), the base or sub-grade has failed (causing recurring problems surface repairs won't fix), the driveway is at the end of its life, or repairs would cost nearly as much as replacement. A simple rule: small affected portion + sound structure → repair; pervasive, structural, or failed base → replace. Watch the cause, too — if a drainage or base issue is driving the damage, it must be fixed or repairs will fail again. Resurfacing is a middle option that renews a sound-but-worn driveway for less than replacement. The calculator estimates repairs (including section replacement); the site also has a new-driveway calculator for full-replacement comparison.

Mudjacking (also slabjacking, or the modern polyjacking/foam-jacking variant) lifts and levels a settled or sunken concrete slab back to position without removing it. Small holes are drilled through the slab and a lifting material is pumped underneath to fill voids and raise it. Traditional mudjacking pumps a cement/sand/soil slurry; polyjacking injects expanding polyurethane foam, which is lighter, cures in minutes, is waterproof, and uses smaller holes — increasingly the preferred method. It's the go-to fix when a driveway, sidewalk, or garage slab has settled (creating an uneven, tripping, or pooling surface) but the concrete itself is still solid (not crumbling or badly cracked); common causes are soil erosion from drainage problems, poor original compaction, or voids forming underneath. The advantages are big: it's a fraction of the cost of tear-out and replacement, done in a few hours, and usable quickly (especially foam). The limits: it fixes settling, not badly cracked or structurally failed concrete, and the underlying cause (like drainage) should be addressed so it doesn't sink again. The calculator includes slab leveling as a repair type.

Cracking comes from shrinkage as concrete cures, settling or movement of the soil/base (erosion, poor compaction, voids), freeze-thaw cycles widening cracks, loads heavier than the slab was built for, tree roots lifting the slab, missing or poorly placed control/expansion joints (joints control where concrete cracks — without them it cracks randomly), and a poor original mix, pour, or cure. Spalling and scaling (surface flaking, chipping, pitting) comes from freeze-thaw popping off the top layer, de-icing salts accelerating that damage, an over-troweled or over-watered surface creating a weak top layer, insufficient air-entrainment in the mix, and general wear. Water is the common thread — poor drainage, pooling, and moisture intrusion drive most concrete problems (base erosion → settling, and freeze-thaw → cracking/spalling), so managing drainage protects concrete. To prevent recurrence: ensure good drainage and grading, seal periodically, avoid rock salt (use sand for traction), don't overload it, and maintain proper joints. When repairing, fixing the cause — drainage, roots, base — is what keeps the repair from failing. The calculator lets you set severity and repair type to match the damage.

Concrete resurfacing — a thin new overlay over the existing surface — can be an excellent, cost-effective renewal for an old but structurally sound driveway, but only when the slab beneath is solid. It works well if your driveway is worn, faded, stained, lightly cracked, or has surface scaling but is structurally sound (no major structural cracks, no significant settling or heaving, and a stable base): after cleaning and prepping, an overlay creates a fresh, smooth, like-new surface, and decorative overlays can even add color, texture, or stamped patterns. It costs far less than replacement, is faster, and extends the life. It's not appropriate when there are serious structural problems — deep cracks, significant settling or heaving, a failing base, or large crumbling areas — because resurfacing over them won't fix the underlying issue and the problems will telegraph through and cause the overlay to fail; those sections need replacement instead. Proper surface prep (cleaning, crack repair, a sound bonding surface) is essential for the overlay to adhere and last. So resurfacing is ideal for cosmetic and surface renewal of a sound driveway, not a fix for structural failure. The calculator includes resurfacing/overlay as a repair type.

Yes — sealing after a repair (and periodically afterward) protects both the repair and the surrounding concrete, and it's an inexpensive maintenance step with a good payoff. A concrete sealer repels water, resists de-icing salts and chemicals, reduces freeze-thaw damage, slows wear and staining, and helps prevent the moisture intrusion that causes cracking, spalling, and base erosion. After resurfacing, patching, or crack filling, sealing protects the fresh repair, helps it blend in, and shields the surrounding concrete from whatever caused the original damage. Timing matters: new concrete and fresh overlays usually need to cure for a period before sealing (follow the product or contractor guidance), and the sealer should be reapplied every 1–3 years depending on the product, traffic, and climate. There are penetrating sealers (soak in, little change to the look) and topical/film-forming sealers (coat the surface, can add sheen but need more upkeep) — the right one depends on your goals and climate. Sealing is especially valuable in freeze-thaw and salt regions. The calculator includes a seal-coat finish as an add-on.

It ranges from a few hours for small repairs to a couple of days plus curing for larger ones — and the curing, not the labor, is usually what keeps you off the driveway. Crack sealing and small patches are often a few hours to a day. Slab leveling (mudjacking/polyjacking) is notably fast — lifting settled slabs takes just a few hours, and with polyurethane foam the slab is often usable within an hour, a big advantage of that method. Resurfacing/overlay takes longer because the surface must be cleaned, prepped, and the overlay applied, then cured before use — often a day or two of work plus cure time. Section removal and replacement is the most involved: removing the old concrete, prepping the base, forming, pouring, and finishing (a day or two of work), then waiting for the new concrete to cure — typically several days to a week before driving on it, longer for full strength. So the labor for many repairs is short, but repairs using new concrete (resurfacing, patching, replacement) add curing days, while crack sealing and foam jacking have minimal downtime. Weather affects the timeline too. The calculator estimates cost; your contractor will say how long to stay off the repair.

Both lift a settled slab, but they differ in material and trade-offs. Traditional mudjacking pumps a cement/sand/soil slurry under the slab through fairly large holes — it's proven and often cheaper per job, but the slurry is heavy (which can contribute to future settling on weak soils), uses bigger drill holes that are more visible, can wash out over time, and needs longer to cure. Polyjacking injects expanding polyurethane foam through small holes — it's lightweight (less load on the soil), waterproof, cures in minutes so the slab is usable almost immediately, leaves tiny, less-visible holes, and won't wash out. Polyjacking generally costs more upfront but is increasingly preferred for its speed, durability, and lighter weight, especially where soil is poor. Mudjacking can still be the value choice for larger areas where its lower material cost adds up and the soil is sound. Either way, the underlying cause of the settling (usually drainage washing out the base) should be fixed so it doesn't recur. The calculator's slab-leveling option covers both methods; your contractor can recommend which suits your soil and budget.

The most important step is fixing the root cause, not just the symptom — most driveway damage traces back to water and the base. Address drainage and grading so water flows away from and off the driveway rather than pooling or running under it (the calculator includes a drainage/regrade fix add-on), since base erosion causes settling and surface water drives freeze-thaw and spalling. Beyond that: seal the concrete after the repair and reseal every 1–3 years to resist water and salt; avoid rock salt and other chloride de-icers (use sand for traction), which accelerate spalling; keep tree roots in check near the driveway; don't park or run loads heavier than the slab was built for; and caulk any new cracks promptly with a flexible sealant before water gets in and freeze-thaw widens them. Make sure repairs include proper control/expansion joints to manage where the concrete cracks. Doing these consistently protects the repair and the surrounding slab, often turning a one-time fix into many added years of life. The calculator's add-ons (drainage fix, expansion joints, seal coat) cover the main prevention measures.
