Understanding the Difference
If you’re maintaining an asphalt surface in Maryland, it’s important to know the difference between crack filling and sealcoating—and how they work together to extend your pavement’s life.
Crack filling addresses individual cracks by injecting hot rubberized material into the gaps. This prevents water from seeping beneath the surface, where it can freeze, expand, and cause more serious damage like potholes or base failure.

Sealcoating: Your Surface Shield
Sealcoating is a protective layer applied to the entire asphalt surface. It helps block out UV rays, water, and chemical spills while restoring a clean, dark finish. Although sealcoating improves appearance and longevity, it doesn’t fix existing cracks—which is why it should be used after crack filling.

The Best Maintenance Strategy
For long-term results, we recommend combining both services. Crack filling stops damage at the source, while sealcoating locks in protection and curb appeal. This dual approach is ideal for Maryland’s harsh freeze-thaw cycles and year-round wear.
