If you already have exposed-aggregate concrete, it’s cheaper to restore and seal it if the slab is stable. Replacing it with asphalt is cheaper only when you’re already forced into base work.
If you’re in Wilmington or nearby, you’ve probably seen this happen. One contractor says your rough, cracked aggregate needs a full tear-out, and another offers a cheaper “cap” (often an asphalt overlay vs. full replacement situation). The real cost swing comes down to scope, not whether it’s concrete or asphalt. It’s whether you’re paying for surface prep and protection on a sound slab, or paying for removal and a rebuilt base because the driveway is moving.
The Decision Hinge: Is Your Slab Still Sound?
If the ground keeps moving, even an expensive facelift can leave you with the same cracks a season later. The fastest way to waste money here is treating settlement like a cosmetics problem.
Restoring and sealing exposed-aggregate concrete only pencils out if the slab is stable—and the exposed aggregate concrete repair cost stays tied to surface prep, not base failure; concrete resurfacing systems are commonly framed as adding roughly 5–10 years when installed and maintained properly. If the slab has stopped acting like one piece, any “surface fix” becomes a short-lived cosmetic spend, and asphalt replacement (with real base work) starts to make more sense.
Use this single threshold, and do not let Angi-style star ratings talk you out of it: if you have vertical movement or ongoing settling, treat it as a structure problem, not a surface problem. Look for cracks with a height difference across them, or tilted sections. Coastal, sandy soils make that more common. If everything is in-plane and the roughness is mostly raveling or non-offset cracks, you’re still in “restore and buy time” territory.
If you catch yourself thinking “it looks terrible, so it must be failing,” pause.
Over-aggressive pressure washing can dislodge aggregate and leave the surface rougher than before, especially on older slabs. Read more in our article: Pressure Washing Exposed Aggregate Ugly concrete can still be sound concrete, and that’s the difference between paying for renewal and demolition.
Cost Reality: Restore & Seal vs Asphalt Replacement
Restoring exposed-aggregate costs what your surface demands in prep, not what the material “is.” If you need heavy cleaning (like pressure washing exposed aggregate concrete) and crack fill, that’s the whole bill. But you’re not paying to move dirt.
Asphalt replacement bids swing on everything under the blacktop: demo and haul-off and new stone base (plus edges)—not just asphalt driveway cost per square foot (many national cost guides show wide ranges for asphalt driveway installation costs per square foot). If you’re telling yourself “asphalt is cheap,” kick the tires on whether the quote includes base work, because that is where the money hides like a trapdoor.
Clean, dry weather and the right cure time matter more than most people expect when you’re sealing a driveway for longevity and traction. Read more in our article: Concrete Driveway Sealing Temperature
Pick the Cheaper Path for Your Situation
A Wilmington homeowner gets two bids and thinks the lower number proves asphalt is the bargain, until they realize one quote is basically an overlay and the other includes the base work they actually need—classic asphalt overlay vs replacement cost confusion. Comparing options only works when you’re comparing the same scope.
The lower price follows the scope, not the material, and that holds in any concrete driveway restoration vs replacement decision. If you assume asphalt is always the bargain, you’ll pay for replacement when maintenance would have done the job.
Choose restore + seal if your exposed-aggregate is mostly cosmetic. Rough/raveling texture, algae slickness in shade, or hairline cracks.
| What you’re seeing | Likely category | Cheaper path | Notes |
|---|---|---|---|
| Rough/raveling texture, exposed stones, light scaling | Surface wear | Restore + seal | Prep (cleaning/patching/crack fill) is the main driver. |
| Hairline cracks or cracks with no height difference | In-plane cracking | Restore + seal | Monitor; seal helps protect and buy time if the slab stays stable. |
| Cracks with height difference, tilted/sunken sections, ongoing settling | Structure/base movement | Replace with asphalt (with real base work) | Treat as a structure problem, not a surface problem. |
| Recurring puddles, soft spots, areas that stay wet/soft after rain | Drainage/base failure | Replace with asphalt (with real base work) | Cost hinges on drainage fixes and rebuilt base, not just asphalt. |
Choose replace with asphalt (with real base work) if you see settlement or drainage-driven failure: offset cracks, tilted/sunken panels, or recurring puddles that don’t drain after a normal Wilmington rain—especially if asphalt driveway lifespan coastal factors into your long-term math. If your main complaint is algae and slipperiness, start with cleaning plus a traction-appropriate sealer before you pay for demolition.
Fresh sealers and sealcoats can stay tacky or track onto shoes and tires in peak summer heat, which can affect how you schedule the job. Read more in our article: Asphalt Driveway Sticky Hot Weather
