Asphalt Driveway Sealcoating
Sealcoating does two jobs at once: it fills the small surface pores that let water and UV degrade asphalt over time, and it gives you a fresh, uniform black finish that hides minor wear. The process starts with a clean, dry surface — any oil spots get pre-treated so the sealer actually bonds instead of peeling within a season.
Crews use commercial-grade coal-tar or asphalt-emulsion sealer (not the thin, big-box-store product), applied by squeegee or spray depending on the surface, in two coats where the driveway sees heavy use.

Asphalt Driveway Sealcoating FAQs
Can you seal a brand-new driveway?
Not right away — fresh asphalt needs 6–12 months to fully cure before sealing. We'll tell you the right timeline if your driveway is newer than that.
Will sealing fix existing cracks?
No — cracks need to be filled first (a separate step) or they'll just telegraph through the new sealer within a season. We always check and quote crack filling alongside sealing.
How long does the job take?
A standard driveway takes 1–2 hours to apply, plus the cure/dry window before you can park on it again.
Do I need to do anything to prepare?
Just move vehicles off the driveway and keep it clear for the cure window — crews handle the cleaning and prep.
