How often should you fill driveway and walkway cracks?
Once a year. On a calendar: July.
Why it matters
Water in a crack becomes frost heave in winter — small cracks grow into broken slabs one freeze at a time.
How to do it
Clean cracks out and fill with the right filler for asphalt or concrete on a dry summer day. Reseal asphalt driveways every few years.
Signs you've waited too long
Cracks widening year over year, or slab edges lifting unevenly.
