Sealcoating cycles, crack filling, pothole repair, and striping. 01 / OVERVIEW ## The Big Picture Parking lot maintenance is one of the highest-ROI line items in a commercial property budget. A maintained lot lasts 20-25 years. A neglected one fails in 8-12. Preventive maintenance costs a fraction of what replacement costs. This guide provides a practical framework for commercial property managers. What to do, when to do it, and how to budget for it. Supreme Seal Coat uses this same framework when working with property management companies across the Treasure Valley. 02 / THE MAINTENANCE FRAMEWORK ## A Framework That Works 01 ### The Maintenance Cycle That Works Commercial parking lot maintenance runs on a sealcoating cycle every 2-3 years, with targeted crack filling and pothole repair in between. Fresh asphalt should be sealcoated after 6-12 months to let initial asphalt oils cure. From there, sealcoat every 2-3 years, fill cracks annually, repair potholes as they form, and refresh striping every 3-5 years. 02 ### Why Crack Filling Matters A hairline crack lets water reach the base. Water erodes the base. Freeze-thaw cycles accelerate damage. What starts as a quarter-inch crack becomes a pothole, and a pothole becomes a section needing cut-and-replace repair. Annual crack filling is dramatically cheaper than the pothole work that follows when cracks are ignored. 03 ### When Pothole Repair Becomes Urgent Potholes create liability risks. Customer vehicle damage and pedestrian injuries are expensive. They also get worse quickly; each vehicle that hits one pushes broken asphalt deeper into the base. Urgent pothole repair should always be cut-and-replace with properly compacted new asphalt, not a quick throw-and-go fill. 04 ### Striping and Compliance Fresh striping signals a well-managed property. Faded striping signals neglect. Beyond appearance, striping is required for ADA accessibility compliance and local fire code. Most commercial lots should be restriped every 3-5 years, with high-traffic lots sometimes needing it sooner. When sealcoating is performed, striping should always be refreshed as part of the project. 03 / KEY TAKEAWAYS ## What To Remember - Preventive maintenance extends commercial pavement life from 10 to 25 years. - Sealcoat every 2-3 years, crack fill annually, stripe every 3-5 years. - Cracks ignored become potholes; potholes ignored become replacements. - Striping is a compliance requirement, not just cosmetic. - Multi-year maintenance contracts are usually cheaper than one-off work. 04 / RELATED SERVICES ## Services Featured [ ### Parking Lot Maintenance Full-cycle maintenance plans for commercial parking lots.
