Get matched with top driveway sealcoating pros in Austin, UT

What causes driveways to crack can vary by driveway material. Sealcoating with the right formula creates a protective "shell" over a driveway. Resealing a driveway on schedule helps to preserve its lifespan substantially by keeping it protected against damage from UV rays, motor oil, chemicals, hail, rain, snow, and more. If you don't reseal your driveway, this will lead to brittleness, cracking, and potholes that can eventually cause your driveway to fall apart.

A good rule for all homeowners is to seal every driveway to protect it. Wait at least three months to seal an asphalt driveway and one month to seal a concrete driveway. You know it’s time to reseal your driveway when it shows obvious signs of wear and tear. It may appear as fading or discolored asphalt, small cracks, and oil stains. If you notice that one area of your driveway seems to dry slower than others, it’s time to reseal.

New asphalt goes through two stages: drying and curing. Drying typically takes 24 to 72 hours, after which the surface is solid enough for light use like walking or careful driving. While you may be able to park on it after 72 hours, the surface is still soft and should be treated gently. Full curing is a much longer process, taking anywhere from 30 days to a full year for the asphalt to reach maximum strength. During this extended curing period, the asphalt is susceptible to damage from heavy vehicles, sharp objects, and high temperatures. Factors like weather, the specific asphalt mix, and application thickness all influence drying and curing times. For the most accurate timeline and to ensure the longevity of your new asphalt, it is always best to consult with your installation contractor for their specific recommendations.

If your asphalt driveway shows cracks, potholes, or standing water, it’s likely time for a repair. Cracks, big or small, let water seep in, weakening the base and causing further damage. Potholes are a sign of this weakening process in action while standing water suggests your driveway has poor drainage, which can cause even more issues. You may also see warping or buckling—a sign of a compromised base layer—or sinking pavement. Spotting these signs early on can help you save yourself a bigger repair bill in the future.
