Research first
Crack sealing typically involves routing the crack and applying a flexible, hot-pour rubberized sealant designed to move with pavement expansion, while crack filling is often a lower-cost surface treatment without routing. Ask which method a contractor is proposing.
Narrow, isolated cracks are generally good candidates for sealing. Wider cracks, alligator cracking, or areas with base failure usually need patching or repair rather than sealant alone.
Crack sealing should happen before sealcoating, and sealcoating should cure before restriping. Sequencing matters for durability of the finished work.
