Sealcoating protects your driveway or lot from UV rays, rain, snow, oil spills, and freeze-thaw cycles. It helps prevent cracks, slow deterioration, and extends the life of your pavement — while restoring that clean, jet-black finish.
Sealcoating enhances appearance and protects your surface — but it won't smooth out deep cracks or rough texture. For that, we recommend our crack repair or infrared patching services before sealing.
Cracks won't vanish completely, but we fill them with hot rubberized crack filler that seals out moisture and stops further spreading. It's not cosmetic — it's structural protection.
Most driveways and parking lots benefit from sealcoating every 2–3 years. High-traffic or weather-exposed areas may need attention more frequently. We'll help you set up a plan that fits your surface.
New asphalt should cure for about 12 months before its first sealcoat. After that, regular maintenance helps lock in durability and slow down oxidation and cracking.
Traditional patching cuts and replaces damaged areas. Infrared patching heats and blends existing asphalt with new material, creating a seamless finish with no cold seams — perfect for potholes and surface damage.
