A 22-year asphalt contractor's checklist. How to tell whether you can patch and seal — or whether it's time for a tear-out and rebuild.
Most homeowners ask the wrong question. It's not "is my driveway broken?" — it's "is the surface failing, or has the base failed?" Surface failures can be repaired. Base failures cannot. Below are the seven indicators we look for during an on-site evaluation, in order of severity.
This is a network of interconnected cracks resembling alligator skin. It only forms when the sub-base has failed — water has gotten under the asphalt and weakened the foundation. The surface is no longer structurally bonded to anything stable.
Patches that pop out within 12 months are diagnostic — they prove the base under the patch is wet, soft, or shifting. We can re-patch them indefinitely, but the only durable fix is to dig down, fix the base condition, and rebuild.
Asphalt is permeable. Trapped water always finds its way to the base. Once it's there, it freezes, expands, breaks the bond, and accelerates failure. If your driveway holds puddles longer than a day, the original grading was wrong — and you can't fix bad grading with sealcoat.
Visible dips, ridges, or low spots that hold water mean the sub-base has compacted unevenly — usually from inadequate original compaction or from water washing out fines. The asphalt isn't the problem; the foundation underneath is.
An asphalt driveway that's never been sealcoated and is past its 20-year mark has lost its binder oils. The surface is dry, oxidized, and starting to ravel — small aggregate stones loosening from the matrix. At that point, sealing alone is too late.
Asphalt edges are the most vulnerable part of a driveway because they have the least lateral support. Crumbling edges typically indicate insufficient edge thickness, no edge support, or repeated tire stress. Limited edge damage can be repaired; widespread crumbling is a tear-out.
Black asphalt that's faded to a chalky gray is just oxidation — UV breaking down the surface binders. This is the easiest fix. A sealcoat application restores the color, replenishes binder oils, and adds 5–8 years to the surface lifespan.
Cost: $150–$500 for crack fill + $0.15–$0.30/sq ft for sealcoat.
Cost: $2–$4 per sq ft. Roughly 40% less than replacement.
Cost: $3–$7 per sq ft for new install, $5–$9 for tear-out + new install. See full pricing guide.
