Driveway Sealcoating FAQs, answered by experts

Every 2-3 years, depending on climate and usage, to protect against weathering and cracking.

It extends pavement life, improves appearance, protects against weather, and reduces maintenance costs.

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.

When comparing installation costs, asphalt is often less expensive upfront than concrete. Asphalt prices typically range from $7 to $15 per square foot, while concrete can range from $3 to $18 per square foot. However, long-term costs should also be considered. Concrete driveways generally last longer (up to twice as long) and require less maintenance, which can make them more affordable over their lifespan. While asphalt has a lower installation cost and is easier to repair, it requires more frequent maintenance, such as sealing, which can add up over time. Therefore, while concrete is more expensive initially, its durability may offset the cost in the long run.

No. You cannot use asphalt products on concrete driveways. To seal a concrete driveway, use acrylic, epoxy, polyurethane, silane, siloxane, and silicate sealers or deep penetration sealers made specifically for concrete. Meanwhile, asphalt sealers contain refined coal tar (asphalt emulsion), water, sand, clay, polymers, and additives and are incompatible with concrete’s surface texture and higher density.
