It's the most expensive confusion in pavement: owners sealcoating asphalt that's structurally gone, and owners repaving asphalt that just needed protection. The two services solve completely different problems, and telling them apart takes about five minutes of honest inspection.

What sealcoating actually does

Sealcoating is surface protection — a sacrificial layer that blocks UV, water and chemicals from attacking the asphalt binder. It restores the deep black look and slows aging dramatically. What it does not do: add structure, bridge moving cracks, or fix a failing base. Sealer on broken pavement is paint on rust.

What repaving actually does

Repaving — whether an overlay or full reconstruction — replaces structure. It's the answer when the pavement itself has failed: widespread cracking, base movement, drainage damage. It costs 10–20x more than sealcoating, which is exactly why you only want to buy it when it's truly time.

A quick inspection

  • Surface gray but tight? Few cracks, no movement underfoot → sealcoat (with crack filling first).
  • Scattered single cracks? Fill them, then sealcoat. This combination handles most pavement under 15 years old.
  • Alligator cracking? Webbed, interconnected cracks mean base failure in that area. Sealer can't help; that section needs structural repair.
  • Potholes, ruts, or standing water? Structure and drainage are gone in those zones. Patch or repave them before any cosmetic work.
  • More patch than pavement? When repairs cover a large share of the surface, repaving usually costs less over time than another round of patches.

The hybrid answer most properties need

Real lots and driveways rarely need only one kind of work. Often the right answer is to repair the failed areas, then fill cracks and sealcoat the sound pavement around them. We make that judgment during every estimate and recommend the less expensive option when it is the honest one.

If a contractor quotes sealcoating without walking your pavement — or quotes repaving without explaining why sealer won't work — get a second opinion.
