Asphalt fails from the top down. Sun oxidizes the binder, the surface turns gray and brittle, hairline cracks open, and water reaches the base — where freeze-thaw cycles and traffic turn small defects into potholes and alligator cracking. Sealcoating interrupts that sequence at the start, for pennies per square foot compared to the dollars per square foot that resurfacing costs.
The math is simple: lots sealed on a two-to-three-year cycle routinely last twice as long as unsealed lots. For property managers, there's a second return that shows up immediately — a freshly sealed and striped lot reads as a well-run property to every tenant, customer, and prospective lessee who pulls in. It's the fastest curb-appeal upgrade a commercial property can make, which is why retail centers and HOA communities put sealcoating on a standing maintenance calendar.
