Driveway Sealcoating questions, answered by experts
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.
Hot-pour sealants have an asphalt cement base that might also include rubber and other materials to allow the seal to flex in hot or cold temperatures. Asphalt emulsion sealants are not heated but are liquid applications that use water and an emulsifying agent to allow the asphalt and water to mix.
Many services include sealing as part of the repair process. Confirm with your contractor.
Whether you should resurface or replace your asphalt driveway heavily depends on its condition. If the foundation is solid and the damage is minor, resurfacing is your best bet because it’s more affordable and faster than replacing the driveway. But if your driveway has foundational problems and/or severe damage, like large, deep cracks and potholes, then it makes more sense to replace it.
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.
