Sealcoating is the cheapest thing you can do to protect an expensive asset. But sealcoat too often and you're wasting money; wait too long and you're paying for repairs instead. So what's the right schedule?
The general rule
Most commercial asphalt lots should be sealcoated every 2 to 3 years. New asphalt should cure for several months — typically a full season — before its first coat.
What changes the timing
Heavy traffic, lots of turning movements, fuel and oil drips, and full sun exposure all wear sealer faster. A busy retail lot or a warehouse with truck traffic may need it closer to every two years, while a low-traffic church lot can often stretch to three. The honest test: if the surface has faded from black to gray and water no longer beads, it's time.
Always crack-seal first
Sealcoat is a surface protectant, not a crack filler. Cracks must be cleaned and sealed before sealcoating so water can't reach the base. Skipping that step lets damage keep spreading under a fresh-looking coat.
Plan it into a maintenance program
The properties that spend the least over 20 years are the ones on a plan — scheduled crack sealing, sealcoating and striping that keep small problems small. We build those plans for churches, schools, HOAs and commercial owners across our service area.
