Step 1: Determine Driveway Conditions    Inspect your driveway for cracks or other damage and fix the problems before you seal your driveway. Cracks, if left unattended, can eventually grow and cause the driveway to crumble. Whether you have an asphalt or concrete driveway, the more proactive you are at repairing cracks and then sealing the driveway, the longer your driveway will last without the need for expensive replacement or resurfacing.
