Driveway Sealcoating FAQs, answered by experts

DIY sealants exist, but professional application ensures uniform coverage and long-term durability.

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.

Professionals restore the surface to a fresh, attractive finish by applying a new, even sealant layer.

If you notice minor cosmetic problems with your driveway, you should seal it. Look out for cracks and holes on the surface, faded asphalt or concrete, and stains from oil and other chemicals. Replacing your driveway may be necessary if you’re dealing with significant problems—¼-inch cracks, large potholes, and puddles from drainage issues. The cost to install an asphalt driveway typically ranges between $4,200 and $9,000, significantly more than resealing. Consider talking to a professional to discuss whether resurfacing your driveway—a midway project between resealing and replacing—is a better option for you.

To extend the lifespan of an asphalt surface, sealcoat it every 2-3 years, repair cracks promptly, and clean it regularly to remove debris.
