As fall approaches in Minnesota, there’s a narrow window to address asphalt cracks before winter’s freeze/thaw cycles turn them into major problems. Water that enters through cracks freezes, expands, and widens the damage — sometimes turning a $200 repair into a $2,000 one over a single winter.
Sign #1: Visible hairline cracks. Even thin cracks allow water penetration. If you can see any cracks in your driveway or parking lot, they should be sealed before the first freeze.
Sign #2: Alligator cracking. This pattern of interconnected cracks resembles alligator skin and indicates base failure. While crack sealing alone won’t fix the underlying issue, it can slow deterioration and buy time before a more extensive repair.
Sign #3: Cracks along edges. Edge cracks where your driveway meets the lawn are especially vulnerable to water damage. These areas often lack proper drainage and are the first to fail.
Sign #4: Gaps between asphalt and concrete. The joints where your driveway meets your garage floor, sidewalks, or curbing are critical weak points. These gaps should be sealed with flexible, rubberized material.
Sign #5: Previous crack repairs are failing. If old crack filler is pulling away or crumbling, it’s time for professional re-sealing with hot-pour rubberized sealant — the industry standard for lasting repairs.
At Asphalt Aces, we recommend crack sealing as part of your annual maintenance routine, ideally before sealcoating. Give us a call for a free assessment of your asphalt’s condition
