Crack filling and crack sealing are not interchangeable. The right choice depends on crack width, movement, season, and whether the lot is on a maintenance or rehabilitation track. Choosing wrong wastes 60-80% of the budget on a treatment that fails within a year.
The core difference
- Crack FILLING: lower-cost, less elastic material, best for non-working cracks under 1/2 inch wide. Typical lifespan 2-4 years.
- Crack SEALING: hot-applied rubberized material that flexes with the pavement, used on working cracks that open/close with temperature. Typical lifespan 5-8 years.
When summer is right for crack filling
- Cracks are dry, clean, and not actively moving.
- Surface temperature is warm enough for material to flow into the crack.
- Treatment is part of a sealcoat prep cycle.
- Budget is for ongoing maintenance, not capital repair.
When fall is right for crack sealing
- Cracks are at their widest (cool temperatures open them up).
- You want material to bond and fully seat before winter freeze-thaw.
- Cracks are working — i.e., they open and close seasonally.
- Lot is structurally sound and you are protecting it from water intrusion.

Diagnostic checklist before choosing
- Measure crack width with a card or gauge — not by eye.
- Check whether cracks follow a pattern (alligator = structural, isolated linear = thermal).
- Look for pumping or staining around cracks (water is already in the base).
- Confirm pavement age and original mix design where possible.
What it looks like done wrong
- Cold-pour crack filler used on a 1-inch wide working crack — fails by spring.
- Hot-pour sealant used on alligator cracking — masks structural failure and delays a needed overlay.
- Crack treatment without surface cleaning — material never bonds.
- Treatment in November with surface temps below 40°F — material skins instead of penetrating.

Common questions
Can we do both on the same lot?+
Yes — filling for minor maintenance areas and sealing for high-movement cracks. A good condition assessment will map both.
How much does crack sealing cost?+
Roughly $1.50-$3.00 per linear foot for commercial work, depending on access and total volume.
How often should we re-treat cracks?+
Crack filling: every 2-3 years. Crack sealing: every 5-7 years. Both should be inspected annually.
