In the Bay Area, it’s generally recommended to seal coat asphalt pavement every 2 to 3 years to maintain its appearance and prolong its lifespan. However, this frequency may vary depending on factors such as traffic levels, weather conditions, and the quality of the previous seal coat. It’s essential to inspect the pavement regularly and seal coat it as needed to protect it from deterioration and maintain its integrity. Consulting with a professional asphalt contractor can provide personalized recommendations based on the specific conditions of your pavement.
