Get matched with top driveway sealcoating pros in Fairview, MT

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

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.

Commercial lots should be sealed every 2-3 years to prevent cracks and weather damage.

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.
