Why Sealcoating Matters in Northern and Central Wisconsin

Living in Northern and Central Wisconsin means our driveways and parking lots handle a lot of weather variety, from hot summer sun to heavy winter snow. Because asphalt is naturally a flexible material, these big seasonal temperature swings can cause it to expand and contract. Over time, that natural movement can create small hairline cracks.

In our climate, the main goal of sealcoating is simply to keep water out of those tiny cracks before the spring thaw and winter freezes hit. When water gets trapped under pavement and freezes, it expands, which is usually how those frustrating spring potholes get started. Regularly applying a fresh sealcoat every few years acts like a fresh coat of stain on a wood deck—it blocks out moisture, shields the surface from sun fading and road salt, and keeps your asphalt flexible and smooth for the long haul.
