FAQs and Maintenance Tips

  • What does the sealcoating process involve?

    We start with thorough cleaning with a power broom, trim any vegitation encrouching on the driveway, then we blow off the debris. We then repair cracks and potholes, treat oil spots if needed, then apply high-quality asphalt emulsion sealer. The process typically takes a few hours for a standard residential driveway.

  • Why should I sealcoat my driveway?

    Sealcoating applies a protective layer (usually coal tar or asphalt-based emulsion) that acts like "sunscreen" for your driveway. It blocks UV rays, reduces oxidation, repels water and chemicals, and helps maintain flexibility.

  • How much does sealcoating and crack filling increase the longevity of my driveway?

    Doing both together provides synergistic benefits. Crack repairs stop immediate water damage, while sealcoating protects the entire surface and helps "lock in" the repairs. Doing this can extend overall driveway life by 50% or more (or add 10–20 years total) compared to neglect.

    Reduces long-term costs dramatically—often cutting lifetime pavement expenses by 65–75% by avoiding early replacement.

  • Is crack filling for cosmetic or does it serve another purpose?

    Crack filling addresses existing cracks before they widen. It prevents water from seeping in, which is one of the fastest ways to destroy the driveway's base layers through erosion or freeze-thaw cycles.

  • How often should I sealcoat?

    After a driveway is freshly paved, you should sealcoat the next year. After the inital sealcoat, you should seal your driveway every 2-3 years to increase the lifespan of your investment.

  • How long until I can walk or drive on my driveway after sealcoating?

    Walking: Wait at least 24 hours.

    Driving: Wait at least 48–72 hours for best results. Avoid turning tires sharply or parking heavy vehicles during this time. Wet or cool weather can extend curing time

  • Do you perform crack filling before sealcoating?

    Yes — it’s a critical step. We clean and fill cracks with a hot rubberized material, then spead a specialized abrasive material to prevent it from sticking to tires during hot weather. Then we apply the sealcoat. This prevents water from getting under the new sealer during freeze-thaw cycles.

  • Do you use coal tar-based sealants?

    No. Coal tar-based sealants have been banned in Minnesota since January 1, 2014, due to environmental and health concerns (high levels of PAHs that can pollute stormwater). We only use safe, environmentally friendly asphalt emulsion sealers that perform well in Minnesota’s climate.

  • Is sealcoating just cosmetic, or does it actually protect my pavement?

    It does both. While it restores a deep black appearance and improves curb appeal, its main job is protection. It slows oxidation, prevents water from seeping into cracks (which leads to base damage during Minnesota winters), and reduces damage from chemicals and traffic.
