Best driveway sealcoating pros near Graeagle, CA

To maintain your asphalt driveway, add a new coat of sealant every three to five years. Pricing varies, but you will pay about $0.08 to $0.50 per square foot from start to finish. You can also choose to add a fill-and-seal layer that includes a layer of aggregate to fortify a damaged top layer of asphalt.

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.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

Yes, it’s possible to seal your driveway too much. Whether you have an asphalt or concrete driveway, sealing it every year opens your driveway to potential damage. Sealing an asphalt driveway annually may cause the seal to crack and peel even more. It may even trap oils within the asphalt that can leave you driving on a soft driveway. Avoid sealing your concrete driveway too much to prevent the concrete from cracking. If water enters these cracks, it can freeze, expand, and cause the cracks to worsen.
