If you’ve gotten two estimates and two totally different answers, you’re not alone. One contractor says sealing or an overlay will do the job, another warns you’ll “just be back in a year,” and you’re left trying to figure out whether you’re maintaining a basically sound driveway or throwing money at a band-aid.
You can decide without guessing if you approach it as a diagnosis, not a simple “seal, resurface, replace” ladder. You’re asking what’s failing: the top layer or the structure underneath, which matters in Wilmington’s heavy rain and damp, salty air. Once you know whether the base is stable or moving, the right option becomes obvious. You’ll be able to compare scope instead of sales pitches, and you can spot a bad recommendation before it takes you for a ride.
The One Decision Point: Is the Base Moving?
If the ground under your driveway is shifting, every gallon of sealer or thin overlay is just a short-term cover charge. You end up paying twice: once for the cosmetic fix, and again when the same cracks telegraph right back through.
A rough surface can make it feel like the only question is crack severity. What saves money is confirming whether anything underneath is shifting, since sealers and thin resurfacers won’t stabilize settling, heaving, or water-trapping material.
Look for vertical displacement or soft spots that flex underfoot.
Storm-driven rain can expose drainage and low-spot problems on exterior surfaces fast in coastal Wilmington.

If they can’t say it clearly, walk away and check their BBB record.
Choose Between Seal, Resurface, or Replace
People get steered into “the middle option” when price becomes the focus and the diagnosis gets skipped. Typical ranges run about $3–$10 per sq ft to resurface (your driveway resurfacing cost) versus $6–$15 per sq ft for full replacement, so the cheap-sounding recommendation can be tempting even when it’s the wrong fit.
Use this rule: pick the lightest option that matches what’s failing, like choosing shoes for the weather, and don’t let anyone nickel-and-dime you into work you don’t need (when to seal a driveway comes down to that same diagnosis). Seal when the driveway is mostly intact and you’re trying to slow water and salt intrusion (think: faded color, tiny surface checking, hairline cracks). Resurface when the base feels stable but the top is worn (moderate cracking without heave or roughness) and you want a new wear layer. Replace when you have movement or geometry problems you can’t “coat away” (settlement or widespread alligator cracking).
| Option | When it fits | Common signs (from this article) | Key caution |
|---|---|---|---|
| Seal | Driveway is mostly intact; goal is slow water/salt intrusion | Faded color; tiny surface checking; hairline cracks | Won’t fix movement or ponding |
| Resurface | Base feels stable; top layer is worn; want a new wear layer | Moderate cracking without heave; roughness; minor spalling or raveling | Thin overlays won’t hide underlying movement |
| Replace | Base/drainage/geometry problems you can’t coat away | Settlement; widespread alligator cracking; recurring potholes; chronic ponding near the garage | Confirm base and drainage work is included in scope |
Bigger work doesn’t automatically buy you more life.
Comparing bids is easier when you can separate scope details from vague line items and upsells. Read more in our article: Compare Roofing Quotes Replacing a stable base can just buy you a larger invoice.
What to ask your contractor in Wilmington
A Wilmington homeowner gets a clean-looking overlay in May, then the first week of hard rain reveals ponding at the garage and cracks reappearing along the low edge. The difference was not the product, it was whether anyone scoped water flow and base prep before promising a quick surface fix.
In coastal NC, don’t accept a recommendation that can’t tie itself to water management or movement, since that shrug-and-sell approach burns budgets fast. Wilmington rain, sandy subgrades, and salty air punish edges and low spots first, so you want an estimate that explains drainage and base condition, not just a new top layer.
Ask these, and listen for specific measurements and scope language:
Written scope language is one of the quickest ways to tell whether an estimate actually includes the prep and corrections you’re paying for. Read more in our article: Written Estimate Materials Labor
-
“Where is the water going in a hard rain, and what grade changes (if any) are you including to stop ponding?”
-
“If you’re proposing resurfacing, what thickness are you actually installing?” (Asphalt overlays commonly run about 1.5–2 inches; many concrete resurfacing overlays are only 1/4–1/2 inch, so they won’t hide movement.)
-
“What’s your plan for cracks: fill only, or full tack coat/bonding across the whole surface before the overlay?”
-
“If you recommend sealing, what schedule do you want me on here?” (How often to seal a driveway depends on age and wear: new asphalt typically needs about 12 months before the first sealcoat; then every 2–3 years is common, and doing it yearly can create a brittle buildup.)
-
“What cure-time and weather window are you assuming for Wilmington humidity and pop-up storms, and when can I drive on it?”
