Uneven driveway leveling or replacement: What to do

You can usually level an uneven driveway when the problem is localized and the surface is still intact. You usually need replacement when the damage is widespread and separating, or it keeps moving because the base is failing.

If you’re in Wilmington or nearby, that “one bad dip” often traces back to water and runoff, or edge washout.

In coastal North Carolina, persistent settling is commonly tied to saturated soils and edge washout, so identifying the cause matters as much as the leveling method.

It’s whether you’re looking at a solid slab that sank in one area (a good candidate for grinding, lifting, or partial replacement) or a driveway that’s breaking down across multiple sections. In the sections below, you’ll get a simple decision test and a match-the-fix breakdown, plus the cost and disruption tradeoffs that help you do it right the first time.

Driveway leveling options: The Decision Test

If your driveway is uneven in spots, you can usually level it when the problem is localized, the slab/asphalt is still in one piece, and you can point to a correctable cause (often water and soil loss at the edge in coastal North Carolina) for uneven driveway repair. If most of the driveway has settled and multiple areas are heaving, or the slope is wrong end-to-end, you’re typically in replacement territory.

Use this quick test: Level when it’s a few sections (not the whole field) and the height change feels like a dip or lip, with cracks that are minor and not separating—this is usually a can you level a concrete driveway situation. That part is straightforward, no matter what This Old House makes it look like. Replace when you see widespread cracking and separated slabs, or ongoing washout from downspouts or runoff. If you’re planning to “just add material on top,” pause. Uneven almost always starts below the surface, not on it.

Surface patterns like widespread cracking and separated slabs are often the clearest early warning that you’re past simple leveling and into repair-or-replace territory. Read more in our article: Driveway Replace Vs Repair

Which Fix Fits Your Spots?

You patch a low spot on Saturday, and by the next big rain the puddle is back (a classic driveway pooling water fix scenario) with a new crack you didn’t have before. That happens when the fix didn’t match what moved underneath.

If you’re staring at one or two ugly low spots, pick the fix based on what changed. Don’t kick the can down the road. Did the slab drop or did an edge lift? The wrong move is trying to “feather in” a thin topper. It’s a quick Band-Aid. That tends to buy you a short-lived cosmetic win, and the bump comes back.

If the low spot is holding water after storms, the real fix is usually correcting runoff paths and pitch—not just lifting the slab. Read more in our article: Best Fix Standing Water Driveway

• Grinding fits when you have a small trip “lip” (often under about 1/2 inch) and the slab is otherwise solid. You trade perfect looks for quick safety.

• Mudjacking or foam lifting fits when a section is intact but sunken (a dip that holds water or a settled apron at the garage) and you want driveway slab lifting. Use this when you want the surface back where it was with minimal disruption, including a polyjacking driveway approach.

• Partial replacement fits when the problem area is crumbling and separating, or when you can see active washout, like a downspout dumping beside the driveway edge and undermining the base.

Cost, Disruption, and Durability

Pricing often reflects the trip and setup, not the size of the low spot. Minimums commonly land around $600–$1,200 for mudjacking and $900–$1,600 for foam injection, even when the uneven area is small.

In Wilmington, the surprise is often the minimum, not the square-foot price. That is the part Angi listings rarely warn you about. Even if you only have one or two low spots, many contractors price leveling like a mobilization job, so it’s common to see mudjacking land around $600–$1,200 minimum and foam injection around $900–$1,600. For a typical sunken section (roughly 50–100 sq ft), many real-world totals end up around $500–$1,500, with foam often running 25–40% higher than mudjacking for similar lifting.

Disruption is usually where leveling wins. Foam or mudjacking often finishes in hours to less than a day, while cutting out and replacing a section can stretch to multiple days once you factor in demolition and cure time (see a transportation case comparison in Wisconsin DOT research). If you need the driveway usable quickly, that matters more than squeezing out the lowest bid, and I think ignoring that is just bad planning.

Durability comes down to whether you fix what caused the drop with a driveway grading and drainage fix. If the spot settled because a downspout has been dumping next to the edge and runoff has been washing out soil, paying for a perfect lift without fixing drainage can still leave you chasing the same dip again. As a money check, when your plan for lifting and crack repair starts pushing about half the cost of replacement, you’re usually better off replacing the problem area (or the whole drive) instead of stacking repairs.
