Driveway Cracks Before Winter: Repair Now or Wait?
Quick answer
Sealing narrow cracks before cold, wet weather is cheap insurance. Water that sits in a crack undermines the slab base and widens the crack every wet-dry cycle.
Warning signs
- Cracks wide enough to hold water or debris
- Sections that have lifted, dropped, or created a trip hazard
- Crumbling or flaking surface (spalling)
- Water pooling on the slab or draining toward the house
- Cracks that grow noticeably season to season
DIY vs professional
Cleaning and sealing hairline to narrow cracks is standard DIY. Uneven slabs, sinking sections, trip hazards, and drainage that runs toward the foundation should be assessed by a concrete contractor.
Cost level
Crack sealing is low cost. Slab lifting is moderate; replacement is a major project.
Repair or replace?
Seal and monitor stable cracks. Replace when sections have separated, settled unevenly, or the surface is broadly deteriorated.
What happens if you ignore it
Trapped water widens cracks and washes out base material, turning a sealing job into slab replacement — and a raised edge is a real trip and liability hazard.
