Do You Really Need Crack Filling Before Sealcoating?

Yes—crack filling is a critical step that helps your sealcoating actually last. Sealcoating protects the surface, but it doesn’t fix existing damage. If cracks are left untreated, water can seep in, especially with Wisconsin’s freeze-thaw cycles, causing the asphalt to break down underneath and leading to premature failure.

Filling cracks with a professional rubberized sealant prevents them from spreading, keeps moisture out, and creates a smooth, stable surface for the sealcoat to bond to. In most cases, skipping crack filling ends up costing more in the long run, so if you want your driveway in Green Bay, Howard, Suamico, Hobart, or Pulaski to last and look its best, it’s a step you shouldn’t ignore.
