Asphalt Sealcoating for Driveways & Commercial Parking Lots
Sealcoating is the single best thing you can do to protect an asphalt driveway or parking lot from the sun, rain, and everyday wear that slowly break it down. It’s also one of A&L Asphalt’s core specialties — we’ve sealcoated everything from single-car driveways to full commercial parking lots across Sonoma, Marin, and Lake County for over 24 years.

Sealcoating for Commercial Parking Lots
Commercial lots see far more wear than a home driveway — constant vehicle traffic, delivery trucks, and daily sun exposure all add up faster. Property managers and business owners typically sealcoat commercial lots every 2 to 3 years as well, though high-traffic lots may need it more often. A well-maintained, freshly sealed lot also makes a real difference in how a business or retail property looks to customers and visitors.

Signs Your Asphalt Needs Sealcoating
Look for a gray, faded appearance instead of the deep black color of fresh asphalt. Small surface cracks that haven't spread into major damage yet are also a sign it's time. If your driveway or lot hasn't been sealed in 2 to 3 years, it's worth an inspection even if it looks fine.
What Sealcoating Won't Fix
Sealcoating is a protective and cosmetic treatment, not a structural repair. If your asphalt has potholes, significant cracking, or base failure, that needs to be addressed with repair or resurfacing first — sealing over serious damage just delays a more expensive fix. We'll always tell you honestly if your property needs repair work before sealcoating makes sense.
What Affects the Cost of Sealcoating
Cost depends primarily on square footage, plus how much crack filling and oil spot priming is needed. A driveway in good condition costs less to seal than one with several cracks that need attention first. We give free estimates so you know the real price before committing.
