Driveway Sealcoating FAQs, answered by experts

Yes, sealing is included to prevent staining and moisture absorption, depending on the stone type.

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.

You shouldn’t directly paint over an oil stain on your asphalt driveway. While painting over might visually conceal the stain, the oil will continue to damage the driveway. Once you’ve noticed the oil stain, it’s important to thoroughly remove it within the next few months since oil stains only take six months before they begin to damage the structure of your asphalt driveway.

Sealcoating is worth the investment because it protects your driveway from damage, extending its life and the timeframe in which you need to replace it. Sealcoating costs around $500 on average, while replacing a driveway costs about $5,000. Sealcoating delays the need for replacement and it also helps keep your driveway looking newer for longer. As an added bonus, sealcoating can boost your property value and curb appeal, making it worth the sealing cost once every five years.

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.
