Parking Lot Reseal Budget Calculator

Asphalt parking lots require periodic seal coating, restriping, and crack patching to prevent costly full overlays. This calculator budgets the three components and converts the total into an annual reserve allocation based on your maintenance cycle — typically every 3 years for high-traffic commercial lots, every 5 for low-traffic suburban office.

How the math works

Seal coating ($0.15-0.25/SF) protects asphalt from UV and water damage; striping ($5-12/stall) refreshes after seal cure; patching addresses cracks before they widen. Recommended every 3 years for high-traffic lots.

Skipping reseal cycles forces full asphalt overlay ($3-5/SF) or rebuild ($8-12/SF) — 30-50x more expensive than maintaining the seal.

Frequently Asked Questions

Cost per SF for seal coat?

$0.15-0.25/SF for spray-applied coal-tar; $0.20-0.35/SF for asphalt-emulsion. Heavy-duty applications add $0.05-0.10/SF.

How long does seal coat last?

2-4 years depending on traffic. Heavy commercial lots reseal every 2-3; light retail/office every 3-5.

Skip and overlay later?

False economy — overlay runs $3-5/SF (15-30x reseal cost) and full rebuild $8-12/SF. The reseal is what extends asphalt life from 8-12 years to 20-25+.
