Most asphalt driveways should be sealcoated every 2-3 years to maintain optimal protection. However, high-traffic areas or driveways exposed to harsh weather conditions may benefit from annual sealcoating. New asphalt should cure for at least 90 days before the first sealcoat application.

Crack filling uses hot rubberized material to fill cracks and prevent water infiltration, ideal for smaller cracks up to ¾ inch wide. Crack sealing creates a flexible bond that moves with the pavement and is better for larger or more active cracks. Both methods prevent water damage and extend pavement life.

Sealcoating typically dries to the touch within 4-8 hours under ideal conditions (70°F and low humidity). However, full curing takes 24-48 hours. Avoid driving on newly sealed surfaces for at least 24 hours, and longer during cooler or humid weather conditions.

Sealcoating requires temperatures above 50°F and no rain for 24 hours, making it unsuitable for winter application. However, emergency crack filling and some repairs can be performed in cooler weather using specialized cold-weather materials. Spring through fall offers the best conditions for most asphalt services.

Professional asphalt repair typically includes damage assessment, debris removal, crack cleaning and filling, pothole patching, surface preparation, and application of repair materials. Many contractors also provide recommendations for preventive maintenance like sealcoating to protect your investment.

Warning signs include: cracks wider than ¼ inch, potholes, standing water that doesn't drain, crumbling edges, or a faded gray appearance instead of deep black. If you notice any of these issues, it's best to have a professional assessment to determine the appropriate repair method.

Quality asphalt repairs can last 5-10 years when properly executed and maintained. The longevity depends on factors like repair method used, quality of materials, weather conditions, and traffic load. Regular maintenance like sealcoating every 2-3 years will significantly extend the life of repairs.
