Frequently Asked Questions

Have questions about asphalt sealcoating, crack filling, or patching? Here are answers to common questions from homeowners and businesses in Green Bay and Northeast Wisconsin.

Contact us

  • You should stay off your driveway for at least 24–48 hours after sealcoating. For best results, longer cure times allow the sealer to fully adhere, helping prevent tracking, scuffing, or surface damage.

  • In Wisconsin, asphalt should typically be sealcoated every 2–3 years. Harsh winters, snow, and freeze-thaw cycles can break down pavement faster without proper maintenance.

  • Crack filling seals gaps and cracks in your asphalt to prevent water from getting underneath the surface. This helps avoid potholes, base failure, and costly repairs.

  • The cost of sealcoating depends on the size and condition of your driveway or parking lot. Contact us for a free estimate based on your specific project.

  • The best time for sealcoating is between late spring and early fall when temperatures are consistently above 50°F.

  • We proudly serve Green Bay, De Pere, Ashwaubenon, Bellevue, Howard, Suamico, Onieda, and the surrounding Northeast Wisconsin communities.
