Crack Sealing Cost by Type

| Alligator | Network pattern | $2.50–$6.00 | Saw-cut, remove, patch |
Crack sealing only works on structurally sound pavement
Sealing cracks in a failing pavement delays the inevitable. If you see widespread alligator cracking, base rutting, or potholes, crack sealing is a temporary fix. Use the Overlay vs. Replace Calculator to assess your pavement's true condition.
When Should You Seal Cracks?
Best time: Spring or Fall
Ideal temps are 50–90°F. Hot-pour sealant needs warm pavement to bond correctly. Avoid sealing in freezing conditions or during rain.
Seal before sealcoating
Always crack-seal first, then sealcoat. Sealcoat over open cracks traps water and worsens damage.
Early is cheaper
A $0.75/LF crack today costs $5–$12/sq ft to replace in 5 years. Routine crack sealing is the highest ROI maintenance you can do.
Frequency: every 3–5 years
Annual inspection with crack sealing as needed extends pavement life significantly. Most lots need attention every 3–5 years.
