Driveway Sealing Cost Calculator
Sealcoating your asphalt driveway every 2-3 years protects it from sun, oil, and water damage. This estimates the cost by driveway size — cheap maintenance that avoids costly repairs.
Frequency: seal every 2-3 years to protect against UV, oil, and water. What moves cost most: number of coats, crack repair needed, and minimum-trip charges from contractors. Regional: 0.85× rural to 1.35× metro. Value: sealing at ~$0.50/sq ft beats asphalt replacement at ~$8/sq ft many times over — it's the cheapest maintenance you can do.
FAQ
How often should I sealcoat my driveway?
Every 2-3 years is typical, depending on climate and sun exposure. Sealing is cheap insurance — it keeps oil, water, and UV from degrading the asphalt that leads to cracks and potholes.
How much does driveway sealing cost?
About $0.35-$0.70 per square foot in 2026 examples — a 600 sq ft driveway runs $250-$450 professionally, or roughly $150 in materials if you DIY.
Is sealing worth it?
Yes. At ~$0.50/sq ft, sealing protects an asphalt surface that would cost ~$8/sq ft to replace. Skipping it lets small cracks become potholes — the most expensive possible outcome.
