Driveway Sealcoating vs. Resurfacing: Which Does Your Driveway Need?
Sealcoating and resurfacing are often confused, but they're completely different services for different problems. Getting this wrong costs money. Sealcoating a driveway that actually needs resurfacing is throwing money at a surface that won't hold. Resurfacing a driveway that just needs sealing is unnecessary expense.
What Sealcoating Does
Sealcoating is a surface treatment. It applies a thin protective layer over existing asphalt to shield it from UV rays, water, oil, and oxidation. It doesn't repair structural damage—it prevents new damage and slows the deterioration of healthy pavement.
Sealcoating is the right choice when:
- The asphalt is structurally sound with no major cracking
- The surface looks faded or oxidized but is otherwise intact
- You want to restore appearance and add protection
- Hairline or minor cracks are present (repair first, then seal)
What Resurfacing (Overlay) Does
Resurfacing adds a new layer of asphalt—typically 1.5 to 2 inches—over the existing pavement. It addresses moderate structural damage: alligator cracking, surface heaving, widespread deterioration. It's significantly more expensive than sealcoating and is appropriate when the base is still solid but the surface has failed.
Resurfacing is the right choice when:
- Widespread alligator cracking covers more than 25–30% of the surface
- Potholes or significant depressions are present
- The surface is uneven or has drainage problems
- Sealcoating has been deferred for too long to save the surface
When You Need Full Replacement
If the base layer (subbase) is compromised—soft spots, settling, drainage failure—neither sealcoating nor resurfacing will fix it. Full depth removal and repaving is the only solution. A reputable contractor will tell you which situation you're actually in rather than apply a surface treatment that won't last.

How do I know if my driveway has alligator cracking?
Alligator cracking (also called fatigue cracking) looks like the pattern of alligator skin—interconnected cracks forming irregular polygons across the surface. It indicates the base is failing, not just the surface. Sealcoating over alligator cracking is a short-term cosmetic fix that won't solve the underlying problem.
Can cracks be repaired before sealcoating?
Yes, and they should be. Cracks wider than a credit card thickness should be filled before sealcoating. We address crack repair as part of our surface preparation on every job.
